What steps will reproduce the problem?
1. Install the App engine SDK
2. Download the Google App Engine Helper for Django
3. Create a project, copy the appengine_django helper into it, start the
test server


What is the expected output? What do you see instead?

I expect it to find the App Engine SDK, but that is not the case, I did NOT
like the suggested workarounds mentioned in the README.


What version of the product are you using? On what operating system?

Mac OS X, initial versions of SDK and google-app-engine-django. 


Please provide any additional information below.

To work around the issue I set in appengine_django/__init__.py the SDK_PATH
to the actual value (/usr/local/google_appengine for my OS)

What steps will reproduce the problem?
1. create template/404.html
2. set DEBUG = False in settings.py@line 19
3. browse to a page not supported by urls.py 

Should see whatever is contained in the 404.html template, instead get a
"<type 'exceptions.AttributeError'>" error page.

This error is avoided if you override TEMPLATE_CONTEXT_PROCESSORS in
settings.py and comment out 'django.core.context_processors.auth':

TEMPLATE_CONTEXT_PROCESSORS = (
#    'django.core.context_processors.auth',
    'django.core.context_processors.debug',
    'django.core.context_processors.i18n',
#    'django.core.context_processors.request',
)

I don't know what new side effects this change might cause though.

When using the manage.py startapp <name> command the generated files are read 
only:

-r-xr-xr-x   1 alex  alex   0 May  3 11:06 __init__.py
-r-xr-xr-x   1 alex  alex  57 May  3 11:06 models.py
-r-xr-xr-x   1 alex  alex  26 May  3 11:06 views.py

What steps will reproduce the problem?
1. run "python manage.py test" on standard app-engine-helper

What is the expected output? What do you see instead?
The expected output is all tests completing successfully.

The actual output is 7 failed tests from commands_test.py. All of them fail
with a message stating that "%1 is not a valid win32 application".

What version of the product are you using? On what operating system?
appengine_helper_for_django-r30, Windows XP, python 2.5

Please provide any additional information below.

It appears that out of the box you cannot call subprocess.Popen on a py
file directly. A simple change to add python as the executable will work on
windows:

    child = subprocess.Popen(["python", "./manage.py", command] + args,
stdin=infd,
                             stdout=fd, stderr=fd, cwd=os.getcwdu())

this of course requires that python is also in the path. If this is changed
 then there is still an error with the test "testRunserver(self)" because
os.kill is not implemented in python on Windows. 

Also, testLoadData is defined twice in that file.

What steps will reproduce the problem?
1. create some fixtures and load them with testserver
2. attempt to access the data
3. not there

What is the expected output? What do you see instead?

the data you added

Please use labels and text to provide additional information.

the problem appears to be that 0.96 calls

    def save(self, save_m2m=True):
        self.object.save()
        if self.m2m_data and save_m2m:
            for accessor_name, object_list in self.m2m_data.items():
                setattr(self.object, accessor_name, object_list)

while 0.97-pre calls:

    def save(self, save_m2m=True):
        # Call save on the Model baseclass directly. This bypasses any 
        # model-defined save. The save is also forced to be raw.
        # This ensures that the data that is deserialized is literally 
        # what came from the file, not post-processed by pre_save/save
        # methods.
        models.Model.save(self.object, raw=True)
        if self.m2m_data and save_m2m:
            for accessor_name, object_list in self.m2m_data.items():
                setattr(self.object, accessor_name, object_list)

this second approach does not actually save the data (and mysteriously
throws no errors)

a workaround is to have appengine_django.serializer.python use it's own
version of DeserializedObject that overrides save() to use the technique
from 0.96, I'm not sure what other issues arise there though

What steps will reproduce the problem?
1. using the existing code upload an app that depends on 0.97-pre, or any
local version of django
2. access your app

What is the expected output? What do you see instead?

expected is the app output, what you get is an error related to loading the
standard appengine django library

Please use labels and text to provide additional information.

the following (from the docs) is necessary to remove the appengine version
of django from the module search path

# Remove the standard version of Django.
for k in [k for k in sys.modules if k.startswith('django')]:
  del sys.modules[k]

generating a base64 of a key that doesn't exist is rather difficult and
poorly portable during development and testing, being able to use just the
"name" part of the key in a fixture is very useful

What version of the product are you using? On what operating system?
r30

Please provide any additional information below.

What steps will reproduce the problem?

With the current configuration any view that uses RequestContext will fail. 
Example:

    render_to_response('entry.html', {'entry': entry}, RequestContext(request))

because django.core.context_processors.auth is not supported (depends on User 
models). If TEMPLATE_CONTEXT_PROCESSORS is copied from the global_settings.py 
to settings.py with  
django.core.context_processors.auth  disabled, then RequestContext will work 
for the other 
processors (MEDIA_URL, etc)

to skip google_appengine if it is there, the django contrib stuff is less
important though certainly is useful if you've brought in trunk

App engine supports memcache now, so should we

Needed to patch sys.modules so that django.middleware.cache.CacheMiddleware
works out of the box

What steps will reproduce the problem?
1. set APPEND_SLASH=True in settings (this should be default condition)
2. uncomment 'django.middleware.common.CommonMiddleware', line in settings.py
3. go to a url that does not end in a slash, where a slash is required by
your urls.py.  For example go to http://localhost:8080/mypath. 
append_slash should redirect this to http://localhost:8080/mypath/ if
needed.  it does not.

I looked through the code and all django middleware and installed apps are
yanked out.  CommonMiddleware seems to work fine in Google App Engine
except for the mail_manager notification on 404s - i *assume* that is not
consistent with the Google Mail api.  This should be pretty easy to fix (or
even not so horrible a thing to let fail) in favor of nice functionality in
commonmiddleware

Options (assuming email is the reason CommonMiddleware is removed):
1 Force settings.SEND_BROKEN_LINK_EMAILS to be false.
2 Create new implementation of commonmiddleware that doesnt send emails
3 Create new implementation of commonmiddleware that uses Google's email API.

Let me know if this syncs with what y'all know and I can send code for #3.

BTW - I am using django trunk.

What steps will reproduce the problem?
1. Copy or link a recent checkout (r7631 in my case) into your project
2. Try running ./manage.py shell
3. Get errors and traceback.

What is the expected output? What do you see instead?
Expecting python shell, get errors and traceback:

There is already a great feature in BaseModel that exists that lets django
use the Model class and serialize the data.  Is there any way the Expando
Model could be featured and integrated with django as well?

I have a plan to translate the following introductory article into Japanese
language.
http://code.google.com/appengine/articles/appengine_helper_for_django.html

Is there any problem for me to make it public?

What steps will reproduce the problem?
1. Map a static directory named "templates" in app.yaml
2. Create a "base.html" django template and an html file that extends it
using this line: {% extends "templates/base.html" %}
3. Test in SDK, it will work. 
4. Deploy using app launcher
5. Attempt to view at appspot will display following error:
TemplateSyntaxError: Template 'templates/base.html' cannot be extended,
because it doesn't exist 


What is the expected output? What do you see instead?
It renders fine in the SDK, throws error once deployed.

What version of the product are you using? On what operating system?
Using App Launcher V. 1.1.0, on Mac OS X Leopard

Please provide any additional information below.
It seems that the SDK is not accurately simulating conditions of the
deployed application. 

What steps will reproduce the problem?
1. Build an app using this framework
2. Include a current copy of django svn trunk
3. attempt to upload the app to GAE

What is the expected output? What do you see instead?
App should be loaded to GAE and able to run.

Applications are apparently restricted from uploading more than 1000 files.  A 
copy of the django 
python module contains 2100 files by itself.  Therefore it is not possible 
(please prove me wrong 
as I am a Python (though not web dev) noob) to upload an app with up-to-date 
django following 
the instructions in this package.  See the output below:

I'm writing some doctests for Rietveld.  I figured I'd just try stuff from
the Django testing docs.  They have a nify Client class that lets you make
requests to your app (without involving HTTP).  They promise that it will
return specially enhanced Response objects.  So I expected that this would
work:

>>> resp = c.get('/mine')
>>> resp.status_code
302
>>> resp.headers['location']
('Location',
'http://testserver/_ah/login?continue=http%3A//DjangoPants%3A8080/mine')

However I get a complaint that the object doesn't have a headers attribute;
I end up using _headers instead.  Are you guys perchance monkeypatching the
Client class in a way that could explain this? Or should I complain to the
Django folks? I'm using Django 0.97.pre and reading the docs for that version.

What steps will reproduce the problem?
1. Putting in code on a page:
from django.core import serializers
data = serializers.serialize("xml", SomeModel.objects.all())  

What is the expected output? What do you see instead?
serialized data of object model. Instead I see error type object
'SomeModel' has no attribute 'objects'

What version of the product are you using? On what operating system?
version 24

Please provide any additional information below.
I'm not sure this is the correct platform for this, but is there any way
someone could post up a tutorial on how to serialize data to and from json
and xml? It would be very helpful to see how it is used with app engine

Seems fairly useful in saving people a step, might be redundant if they
have it installed already

( svn co http://googleappengine.googlecode.com/svn/trunk/ google_appengine )

What steps will reproduce the problem?
1. I setup the environment on the Mac like it is supposed to be
2. I create models and views and do url matching
3. My models are created like on the Google App Engine Introductory
tutorial
(http://code.google.com/appengine/docs/gettingstarted/usingdatastore.html)
4. I import the models into my views and request the web page

What is the expected output? What do you see instead?

I expect the model to import. Instead I get the following error:

When submitting a form with enctype="multipart/form-data", the form fields
are not properly parsed before sending to the django view method.

What steps will reproduce the problem?
1. create a form with enctype="multipart/form-data"
2. map the form using django urls
3. try and get data from the form in the view via the request.POST[] or

Using django trunk.

Did some digging, but not sure if the problem is on the app engine or
django side.  File uploads work fine when working solely with the Google
webapp framework.

Support for:

* Toggling debug off when publishing and on when running development server
* Minifying Javascript/CSS when publishing

What steps will reproduce the problem?

 * Support for the skip_files option in app.yaml is not working in the current
-  SDK release. This means that if you have choosen to put a copy of the Google
+  SDK release. This means that if you have chosen to put a copy of the Google
   App Engine SDK inside your project at google_appengine/ you will need to
   remove it before running appcfg.py or you will upload the entire SDK to your
   account, taking up more of your file quota than is necessary.

What steps will reproduce the problem?
1. Create a project using one appengine account (e.g. [email protected])
2. appcfg update . (and enter your username and password so that it is
saved in .appcfg_cookies)
3. Create another project using a different appengine account (e.g.,
[email protected])
4. appcfg update . (in the new project) 

What is the expected output? What do you see instead?

It should ask me for my email address and password and store those separately.

Instead I get:

Loaded authentication cookies from /Users/aral/.appcfg_cookies

Error 403: --- begin server output ---
You do not have permission to modify this app.

The workaround, when you have more than one appengine account, is to use
--no-cookies for one of them and always enter your username and password.

I using the app engine helper with GAE and Django.  For my app, I need to
authenticate users.  

So when a user is logged in...

Should request.user == users.get_current_user() ?

What is the difference?  In my app, they are not ==  (Although you can get
the same display result using either command).  Also, I only can create an
UserReference instance via users.get_current_user().  

What steps will reproduce the problem?
1. Create a model with a required field and use the 'exclude' directive in
a Model form to exclude that field
2. Create a bound form object from the post data from that form
3. Call save(commit=False) on the form object (with the intention of
assigning a value to the required field later before saving)

What is the expected output? What do you see instead?

There is an exception because the required field is not present.

The form should not be validated with commit=False.

See the note near the bottom of this page:
http://www.djangoproject.com/documentation/modelforms/

If you specify fields or exclude when creating a form with ModelForm, then
the fields that are not in the resulting form will not be set by the form’s
save() method. Django will prevent any attempt to save an incomplete model,
so if the model does not allow the missing fields to be empty, and does not
provide a default value for the missing fields, any attempt to save() a
ModelForm with missing fields will fail. To avoid this failure, you must
instantiate your model with initial values for the missing, but required
fields, or use save(commit=False) and manually set any extra required fields...

Hi there,

sorry this is all pretty new to me. So maybe this is just an 
misunderstanding on my side. Here is what I want to do.

+ I use Django with Google AppEngine
+ I want to use Django flatpages to display static content
+ In my site setup I inherit from flatpages admin form and add TinyMCE to 
edit content (this works with Django)

As far as I understand in AppEngine the admin pages are different (only a 
subset is available). Are flatpages available at AppEngine-Django? How do 
I add the TinyMCE to the admin form?

Best regards,
Mark Fink

Along with issue 27, the memcached session backend can now be supported.
(This patch is against r30 and includes the patch for issue 27).

What steps will reproduce the problem?

2. runs 53 tests: get 7 errors
3.

What is the expected output? What do you see instead?
Expect the tests to succeed...

What version of the product are you using? On what operating system?
Version of Django Helper downloaded yesterday (31 May); version of Django
downloaded yesterday from svn trunk; python 2.5.2 (reinstalled it yesterday).


Please provide any additional information below.

The installation process was actually quite a hassle.  The Google SDK was
installed using the msi installer.  I had Python previously installed.  I
downloaded the Helper and tried to run manage.py.  It could not import
YAML, so I had to find it in the google sdk, and run the setup.  It could
not find webob, so I had to add a python path variable.  Finally got it to
work (more or less).

Decided to run manage.py test and got the following output.  So far I've
only created a small 'hello world' app - so I don't know if the test result
indicates problems with my environment or just issues with Windows
compatibility (or with the SDK installer).

What steps will reproduce the problem?
1. With Publisher acting as base model, enter this code in url conf

from django.conf.urls.defaults import *
from django.views.generic import list_detail
from mysite.books.models import Publisher

publisher_info = {
    "queryset" : Publisher.all(),
}

urlpatterns = patterns('',
    (r'^publishers/$', list_detail.object_list, publisher_info)
)



2. When you hit the page based on the Generic Views of Objects on django's
chapter 9 book, you get an error 

'Query' object has no attribute '_clone'


What is the expected output? What do you see instead?
To output the content into an html page

What version of the product are you using? On what operating system?
Latest version on XP

Under Accessing the Google App Engine SDK

It says "On Linux or Mac OS you can use a command like the following..."

I cannot determine what the  /path/to/google_appengine replacement text
should be. 

Google provides a GoogleAppEngineInstaller that installs an application. 

How do I setup the Mac so I can use the terminal to run the commands you
instruct should be run?

What steps will reproduce the problem?
1. located django trunk and removed auth, admin and databrowse dirs as 
mentioned in the docs.
2. changed the main.py according to docs.
3. tried to runserver

I tried the first steps of the tutorial and ran into a lot of trouble;
basically, I got a big bad traceback saying django could not be imported
when I sent my first request to localhost:8080 -- even though the initial
bootstrap of manage.py successfully imported it!  (I used the technique of
linking the SDK to mysite/google_appengine.)

It turned out that this was due to my having a copy of django in the
site-packages directory of the Python version I was using (2.5).  Clearing
out site-packages made the problem go away.  You may want to mention this
caveat somewhere in your README or in the article.

(Also, the article skips the step of linking the SDK.  Without this nothing
works...)

cached methods sometimes lose global variables after exceptions are thrown 

this is evident when using django because it's routing function caches the
method object after the first lookup, when that method reports an exception
the behavior of the dev_appserver (and production) appears to be to clean
up the imported modules; however, since the reference to the function
object still remains but modules whose contents it referenced have since
been garbage collected, the next call to that function will have all its
global variables set to None

The comparsion functions __eq__ and __ne__ are missing in BaseModel.
Without these comparsions the templatetags {% ifequal ... %} anf {%
ifnotequal ... %} won't work.

The attached patch simply re-implements Django's Model.__eq__ and
Model.__ne__ for BaseModel using the already implemented _get_pk_val() method.

Alternatively the comparsions could be implemented in
google.appengine.ext.db.Model, but I'm not sure if this is the expected
behavior for db.Model instances - for using BaseModel with Django templates
these functions are required.

Please use labels and text to provide additional information.

Integration with the appcfg commands, just a shortcut so you can do things
like python manage.py update

We may want to change the command names, if that is the case the args will
have to be munged a bit, namely whatever the name of the command we use is
it will have to be replaced by the name of the appcfg.py command so that
its parser works properly.

Patch attached.

now, i have perhaps a less usual setup for my app as I had to touch
manage.py to get my environment running as I am running from the unzipped
google_appengine rather than some sort of "installed" version

in my manage.py I've added

sys.path.insert(1, "google_appengine")

and in my project's root dir I have the unzipped directory of the SDK

without this addition running `python manage.py` throws:

Traceback (most recent call last):

dropping the google directory from the sdk produces errors once runserver
is called

I am still digging through the code to find the root of this, the dev
server in general appears not to totally respect the sys.path for its imports 

the somehow related bits from google.appengine.tools.dev_appserver

  url_matcher.AddURL('/_ah/admin(?:/.*)?',
                     admin_dispatcher,
                     DEVEL_CONSOLE_PATH,
                     False,
                     False)


PYTHON_LIB_VAR = '$PYTHON_LIB'
DEVEL_CONSOLE_PATH = PYTHON_LIB_VAR + '/google/appengine/ext/admin'

the PathAdjuster will later on replace "$PYTHON_LIB" with google_appengine
in my case (the root of the SDK)

any attempts to poke that variable lead to failure as the path will be
taken as a literal import path

What steps will reproduce the problem?
1. run the command rst2html.py README > README.html

What is the expected output? What do you see instead?

it generates but with the following errors and warnings:

What version of the product are you using? On what operating system?

revision 13

Please provide any additional information below.

Attached is a patch to fix the errors

I just upgraded to the r30 version and chaining urls.py files using include() 
seems broken.  I'm 
not sure what version I was running previously, where this worked (I can't find 
a version # in any 
of the django helper files).

Here's my top-level urls.py:
urlpatterns = patterns('',
  (r'^island/', include('island.urls')),
)

and then the urls.py inside the island directory:
urlpatterns = patterns('',
  (r'^$',                  views.Index),
  (r'^create$',            views.CreateIsland),
  (r'^(\d+)$',             views.ShowIsland),
  (r'^(\d+)/(\d+)x(\d+)$', views.BulldozeSquare),
)

And the error message:
Using the URLconf defined in urls, Django tried these URL patterns, in this 
order:
^island/ ^$
^island/ ^create$
^island/ ^(\d+)$
^island/ ^(\d+)/(\d+)x(\d+)$
^$
^index.html$
The current URL, /island/create/, didn't match any of these.



It looks like it is doing a weird thing where it is concatenating the two 
patterns, poorly.  Was this 
an expected change?  I looked in CHANGES but didn't see anything that makes me 
think this was 
intentional.  

What steps will reproduce the problem?
1. On mac osx, install
http://googleappengine.googlecode.com/files/GoogleAppEngineLauncher-1.1.0.dmg.
From a new terminal, verify that dev_appserver.py command is available in
the path.
2. Download
http://google-app-engine-django.googlecode.com/files/appengine_helper_for_django
-r30.zip
and unzip. Go to the extracted directory. 
3. Run "python manage.py runserver"

What is the expected output? What do you see instead?
The above steps are according to article at
http://code.google.com/appengine/articles/appengine_helper_for_django.html

It is supposed to run the server.

But instead it says:
[vinay@osx-zen appengine_helper_for_django]$ python manage.py runserver
The Google App Engine SDK could not be found!
See README for installation instructions.


What version of the product are you using? On what operating system?
[vinay@osx-zen appengine_helper_for_django]$ cat VERSION 
VERSION=30
TIMESTAMP=1211291553

On Mac OSX 10.5.3

Please provide any additional information below.

What steps will reproduce the problem?
1. try to initialize djangoforms.BaseModelForm with existing model instance

What is the expected output? What do you see instead?
The data attribute in the dictionary for forms.BaseModel should be set
with object_data - but that never happens.

Please provide any additional information below.
Just fix the line in the BaseModelForm constructor
    kwargs = dict(data=data ...
with
    kwargs = dict(data=object_data ...

What steps will reproduce the problem?
1. Copy the django helper
2. copy google_appengine to the directory (windows environment)
3. run manage.py runserver as stated in article

Please provide any additional information below.
I followed the instructions from the article.
The page loads on the browser but I get all those warnings!

From KNOWN_ISSUES:

"To use a local copy of Django you can place it in the 'django' subdirectory
  of your project."

This works with revision 25 but not with revision 26.

Using r26, I still get django 0.96 (my local copy is the latest django svn)

What steps will reproduce the problem?
1. followed the tutorial at
http://code.google.com/appengine/articles/appengine_helper_for_django.html
2. entered `from motivator.models import Poll` in the textarea at
http://localhost:8080/_ah/admin/interactive

What version of the product are you using? On what operating system?
r30, windows vista 

this is my first django app, I don't know whether to use the django helper
or just modify the gift list till it suits me, but that doesn't seem like a
good idea. base the tutorial on that because my views aren't importing from
google.appengine.ext

What steps will reproduce the problem?
1. install django under app/django
2. try to use development features
3. FAIL

What is the expected output? What do you see instead?
Helper checks for PARENT_DIR/django, but does not add PARENT_DIR/django to
sys.PATH


What version of the product are you using? On what operating system?
SDK 1.1.0, Helper r30, OSX


Please provide any additional information below.

This works:
# Remove the standard version of Django if a local copy has been provided.
if os.path.exists(os.path.join(PARENT_DIR, 'django')):
  sys.stderr.write("Found local version of Django!\n")   
  sys.path = [os.path.join(PARENT_DIR, 'django')] + sys.path
  for k in [k for k in sys.modules if k.startswith('django')]:
    del sys.modules[k]  

I have written some middleware and helpers which integrate with Google's
Users API. I've based it somewhat around how Django's Authentication stuff
works.

I've attached a zip file of the code, I have a bzr branch up at
http://gnaw.yi.org/~ycros/bzr/google_auth/ (sorry, I don't use svn for my
own projects) and I have documentation up at
http://gnaw.yi.org/~ycros/docs/django-google-auth/

The only issue I have with the code at the moment is that I haven't written
any tests for it yet.

I was going to start my own project on Google code, but I thought I'd run
it past you guys to see if you wanted to integrate it.

I'm happy to license the code under the Apache License 2.0.
