Guestbook

Guestbook is an example application showing basic usage of Google App Engine. Users can read & write text messages and optionally log-in with their Google account. Messages are stored in App Engine (NoSQL) High Replication Datastore (HRD) and retrieved using a strongly consistent (ancestor) query.

Products

• App Engine

Language

• Python

APIs

• NDB Datastore API
• Users API

Dependencies

• webapp2
• jinja2
• Twitter Bootstrap

E2E Test for this sample app

A Makefile is provided to deploy and run the e2e test.

To run:

 export GAE_PROJECT=your-project-id
 make

To manually run, install the requirements

pip install -r e2e/requirements-dev.txt

Set the environment variable to point to your deployed app:

export GUESTBOOK_URL="http://guestbook-test-dot-useful-temple-118922.appspot.com/"

Finally, run the test

python e2e/test_e2e.py

Deploy to App Engine

Deploy this from a terminal with the Google Cloud SDK installed.

The index.yaml needs to be built first by running:

 gcloud app deploy index.yaml

Wait for indexes to build in datastore then run:

 gcloud app deploy app.yaml

README.md

Without an "application:" stanza in app.yaml, Google App Engine Launcher considers the project invalid.

Launcher displays the project in red text and disables all of the buttons when that project is selected.

internal server error

I want to be friends with app engine but so far no luck. please help.

This is the error message

This is the input used to generate that message

I have deployed the application according to the tutorial : https://cloud.google.com/shell/docs/quickstart#use_your_home_directory

and getting error when I am acceing the appliation in browser:

README markdown not working

I think that renaming README to README.md will make the Markdown work.

Bootstrap error

When resizing a browser window the navbar behaves strangely - above 980 pixels wide there is a login button, but below 980 the entire navbar moves down, the login button disappears, replaced by a right toolbar expand icon that does nothing.

Bootstrap lint https://github.com/twbs/bootlint/wiki reports a number of warnings and one error: E013 - row children must be columns. Index.html has a container div with a row div, but the items under the rows (greetings, form, and logout button) are not in column spans. I don't know if that error has anything to do with the strange navbar behavior, but just on general principles the page should lint cleanly.

Can we have a Cloud Firestore version? Or maybe two?

I'm in doubt about which mode to use for a new app - the emulated datastore mode or the native mode. Examples using both would be pretty nice.

i'm a newer to GAE. And after googled the errors all day, i still had no idea how to deal with it. Anyone help?

Makefile refers to appcfg.py which has been replace by the gcloud CLI

See https://github.com/GoogleCloudPlatform/appengine-guestbook-python/blob/master/Makefile#L23

A minor typo (maybe)

I am a beginner at python so don't know for sure if its a typo or not .
In code of guestbook.py
application = webapp2.WSGIApplication([
('/', MainPage),
('/sign', Guestbook),
], debug=True)

Didn't it look it has extra comma after Guestbook.

My project

application needs to be app for this example to work

When it's application instead it gives me this error:
ImportError: <module 'main' from '/Users/***********/main.py'> has no attribute app
