bogdal / django-gcm Goto Github PK

It would be really awesome if it had support for bulk push. If its already implemented, where can I get docs on using it.

Thanks,

Hi, thanks for making this app!

Just wondering why there's a forced queryset ordering on the lastupdated field for a device? If I have an incredibly large number of devices and I need to evaluate them in a queryset for any reason, there's an unnecessary expensive sort placed on them. I get why you'd want to do it for maybe the admin form but at the model level I'm not sure it's worth the performance hit?

From the change 3 days ago but it only showed up today in our Jenkins builds :-(

Error in migration: vcm:0002_auto__chg_field_device_reg_id__add_unique_device_reg_id
STDERR: FATAL ERROR - The following SQL query failed: ALTER TABLE gcm_device ADD CONSTRAINT gcm_device_reg_id_1d569ade4b517e81_uniq UNIQUE (reg_id)
The error was: (1170, "BLOB/TEXT column 'reg_id' used in key specification without a key length")

I think it has to be turned into a varchar field first...

This project needs better test coverage in that section, more specifically, all of the handling on the server. Especially error handling, but even success verification.

since dependency on tasty, the gcm is not compatible with 1.9 due to django-tastypie/django-tastypie#1395

Moreover, as disscussed there, get_cache has been removed from django, which is used by tasty

It does work with version django-tastypie-0.12.2.dev0 which is not in the pip repo. The dependencies could be updated.

How to use gcm with topic subscribing support?
If i put in send_message() to parameter, i get error bad request.

I would like to add a few optional arguments to the

    values = {
        'registration_ids': regs_id,
        'collapse_key': collapse_key,
        'data': data
    }

How can I do that ?. Is there an easy way to override this ?

Hi,

Currently the unregister endpoint is saving the dev_id for marking them inactive. Now the issue is:
If some user decides to send false dev_id (without reg_id) to unregister endpoint, The dev_id will be stored with reg_id = null. Now if the same user again send the false dev_id, this will cause IntegrityError: duplicate key value violates unique constraint "gcm_device_reg_id_key" DETAIL: Key (reg_id)=() already exists., which will send repeated mails to django site admin.

I want to know your views on this.

I have installed django-gcm and the android client. The android app is already install and I can see in admin page it was register but how can I send message to the android client? Sorry if i miss the documentation.

In model why dev_id is unique but reg_id is not? And what is dev_id for?
And reg_id is TextField, why?

I have tried to install django-gcm but it's failing due to a dependency on django-tastypie. I also tried to install django-tastypie first but django-gcm still fails to install. Currently, django-gcm 1.0.6 is working and installing. It's just 1.0.7 that is failing for me to install.

$ pip install django-gcm
Collecting django-gcm

Requirement already satisfied (use --upgrade to upgrade): django>=1.6 in /home/vagrant/virtualenvs/nextdrop/lib/python2.7/site-packages (from django-gcm)

No matching distribution found for django-tastypie>=0.12.2-dev (from django-gcm)

I may be being dumb, Is it possible to somehow extend the model to store additional data about the user without modifying the package? Or would the best way be to modify the package? Say if I wanted a link to a User or something?

django.conf.urls.patterns() is deprecated and will be removed in Django 1.10. urlpatterns should be updated to be a list of django.conf.urls.url() instances instead.

Shouldn't the AbstractDevice model have a M2M field mapping to users from the auth_user table? I believe this app should have a built in way of mapping to users.

Currently there is nothing logged in entire repository. There are only 2 singals and that are for register and unregister. I want to add Logging at various points like message sent, failure received, device_id and failing reason mapping etc.

I'll create a PR if required.

The requests provided in the documentation won't work when adding user field to device. Instead of:
curl -X POST -H "Content-Type: application/json" -d '{"dev_id": "test", "reg_id":"abcd", "name":"test device"}' http://localhost:8000/gcm/v1/device/register/
it should be:
curl -X POST -H "Authorization: apikey [email protected]:<api_key>" -H "Content-Type: application/json" -d '{"dev_id": "test", "reg_id":"abcd", "name":"test device"}' http://localhost:8000/gcm/v1/device/register/

GCM Application server in Django is definitely a great idea and it would be very useful if only I could understand how to use it.
Unfortunately, IMHO the documentation is too sparse to understand the usage completely.
Adding some detailed docs would be a great enhancement, and will also help some developers contribute to this project.

Some quick points on what the docs need.

(1) How django-gcm fits in the GCM architecture, http://developer.android.com/google/gcm/gcm.html?

(2) Giving a general idea of why is a GCM Application server necessary, and what are the gaps django-gcm fills up.

(3) A complete tutorial explaining the 3 step working (Registration, Sending Message and Receiving Message) of GCM with django-gcm and the sample app that you have created as a separate repository. (A PDF or online blog link that explains this with some snapshots will be nice)

I will add some nice docs if I understand how to use it.

Please, fix wrong pytz version dependency. Does it really works only with pytz==2013.8 and not with any later versoin???

Stable version of django-rest-framework supports Django 1.9 #41.

One functionality that is not currently supported by django-gcm is support for device groups. This would allow multiple devices to be registered on one notification key. Is this something that could be supported in the model of Django-gcm?

While registering a device with required parameters through angular, I get a 400 from the server.

var req = {
         method: 'POST', 
         url: base_url,
         headers: {
            'Content-Type': 'application/json',
            }, 
         data: data,        
        }

        $http(req).
        then(function(response){
            deferred.resolve(response);
        }, function(data){
            console.error(JSON.stringify(data));
            deferred.reject();
        });

This is the error response from the server:

{
    "data":{},
    "status":400,
    "config":{"method":"POST","transformRequest":[null],"transformResponse": [null],"url":"http://192.168.0.103:8000/gcm/v1/device/register/","headers":{"Content-Type":"application/json","Accept":"application/json, text/plain, */*"},
    "data":{"dev_id":"test","reg_id":"test","name":"Test"}},
    "statusText":"BAD REQUEST"
}

A valid POST request is being sent from the client side, it is possible that the data is available in request.data rather than request,POST, in this case, it is probably causing an error in de-serailisation.

There are few documentation issues/hurdle to get things working:

1. So once one installs django-gcm one has to run following commands right?

python manage.py syncdb
python manage.py migrate

1. In settings.py one should be entering key generated for server app, browser app or Android app for GCM_KEYS?
2. I compiled the associated android pager program and installed it on my system.
   I got what one needs to set GCM_SENDER project number from google app server.

But not clear what should value of API_URL should be?

static public String API_URL = "<url_to_your_application>/gcm/v1/device/";

If someone can show me how to get this working, I will be more than happy to update documentation.

Hi,

do you have any plans to integrate XMMP and some API for upstream messages?

Hi,
i register with reg_id and dev_id, and then call gcm register on my server, i get message SUCCESS, but:

status code: 500

and then GCM doesn't work..
how can i debug this?

Are there plans to support Google Cloud Messaging (GCM) Cloud Connection Server (CCS) as well?? Its XMPP based instead of HTTP. It has many advantages over sending messages via HTTP.

We already use this library in our app but after facing reliability/consistency issues with GCM, we're looking into an XMPP based solution.

I have a problem with extending the model, when I try to python manage.py makemigrations gcm, the console tells me there is no changes and I cannot migrate anything.

Above error while sending message to client. Any leads?

gcm/v1/device/register/ post request works perfect with default django-gcm model but if I extend device model to add user field and make POST request, it fails without any response.

My extended model is as follows,

####models.py

from django.conf import settings from django.db import models
from gcm.models import AbstractDevice

class Device(AbstractDevice):
user = models.ForeignKey(settings.AUTH_USER_MODEL)

####Added my app url in main urls.py

url(r'', include('contrib.device.urls')),

####my app urls.py

from django.conf.urls import patterns, include, url

from .resources import AuthResource

gcm_api = Api(api_name='v1')
gcm_api.register(AuthResource())

urlpatterns = patterns('',
url(r'^gcm/', include(gcm_api.urls)),
)

####resources.py

from gcm.resources import DeviceResource
from tastypie.authentication import ApiKeyAuthentication

class AuthResource(DeviceResource):

class Meta(DeviceResource.Meta):                                                                                                              
    authentication = ApiKeyAuthentication()

    qs = super(AuthResource, self).get_queryset()

#### Code added in settings.py

App added under INSTALLED_APPs

'contrib.device',
'tastypie',
'gcm',

Variables added

GCM_APIKEY = "My App key"
GCM_DEVICE_MODEL = 'contrib.device.models.Device'

What I am doing wrong? Please help.

Thank you.

When checking out the API-key project and attempting to register a device, I get a bad request
However, the data passed is OK. This is my first time using Django, I don´t know where to look for further information.

Also, a new ApiKey is not generated upon creating a new user. As far as I can see from the documentation, this should have happened?

I have followed the django-gcm documentation to setup gcm for my project. I was experiencing problems while sending message to gcm registered device, I was able to send something to the gcm registered device but on the android device it was coming as null. Here is the link I am following

http://django-gcm.readthedocs.org/en/latest/sending_messages.html

so I changed this line
my_phone.send_message('my test message', collapse_key='something')

to
my_phone.send_message({'message':'my test message'}, collapse_key='something')

and it got working fine for me and I am receiving a proper message so I am suggesting a little change in the documentation so that others won't get into problems.

Setting environment variables HTTP_PROXY is not appropriate.
Why is not provided in the advanced settings?

Canonical IDs are sent as a response by the GCM server in case the registration ID changes for a client. The number of canonical IDs are given by the "canonical_ids" key in the response JSON. For the corresponding recipient, the registration_id on the server should be replaced by this canonical ID.

The response body format is given here: https://developers.google.com/cloud-messaging/http#response

Please check the 2nd example from this link : https://developers.google.com/cloud-messaging/http#example-responses

Hi,

I'm sending a JSON payload of the following form

'{"reg_id": "<registration id>", "dev_id": "<device id>", "name": "A Device"}'

Running $./manage.py gcm_messenger --devices gives me the following.

(#1) None

The device is registered, but the name is set to None, for some reason. Any idea why that might be happening?

PS: Thanks for the great work :-)

I have problem, gcm is sending 4 messages when rest save object.
Does anyone else had this problem?

I am encountering an issue that when i send a message , the message string after a space is omitted.
e.g. if i send "check now"
Only check is being shown in the Dialog.

Edit : This is happening when i am sending messages from console.
There is no problem if i send messages from python manage.py shell.

Hi,

I am using this function to push messages to my devices and I've got some problems. The first 20 messages are received instantly but after 20, there is delays (like 30 secondes and more).
Device.objects.all().send_message({'id': '{}'.format(msg),})

This problem is not present when I push from "phpfiddle.org" for example.

Thank You

Hey,

I am able to register the device, but when I try sending a message even by django orm, I get this error.

It works when I use it with my development server. But when I try doing it from heroku this is the error I receive.

It is not clear from the documentation what sort of payload unregister accepts. What should be the contents of the JSON?

The GCM server has responses in JSON that need to be handled. I have the link here:
http://developer.android.com/google/gcm/http.html

error: String describing an error that occurred while processing the message for that recipient. The possible values are the same as documented in the above table, plus "Unavailable" (meaning GCM servers were busy and could not process the message for that particular recipient, so it could be retried).

Is this not supported? Couldn't find anything on the documentation for this.

I have it implemented locally on my side for this.
