Invalid field name

[arikgelman]

Hi,

First I want to say thank you for this amazing package!

I am getting this error when trying to subscribe using chrome:

django.core.exceptions.FieldError: Invalid field name(s) for model SubscriptionInfo: 'expirationTime'.

I tried to remove the field 'expirationTime' from the dictionary under views:

`# We at least need the user or group to subscribe for a notification
if request.user.is_authenticated() or group_name:
# Save the subscription info with subscription data
# as the subscription data is a dictionary and its valid
print(subscription_data)
subscription_data.pop('expirationTime')
subscription = subscription_form.get_or_save(subscription_data)
web_push_form.save_or_delete(
subscription=subscription, user=request.user,
status_type=status_type, group_name=group_name)

        # If subscribe is made, means object is created. So return 201
        if status_type == 'subscribe':
            return HttpResponse(status=201)
        # Unsubscribe is made, means object is deleted. So return 202
        elif "unsubscribe":
            return HttpResponse(status=202)`

And it worked but sending notifications to the subscribed browser is not working.
By the way Firefox is working great.

Please help,
Thanks!

Hi @arikgelman, Sorry for the problem and the delay in replying.
I hope to look on it later today or tomorrow. Let me know if you have any more information regarding it.

Hi! I have the same problem, sending notifications to the subscribed browser is not working. Did you solve it?

[arikgelman]

No, still waiting for a fix

[safwanrahman]

Sorry, I could not manage time to work on this due to University and work pressure.
I am hoping to work on this in the holiday period, but cant promise.
Are you guys interested to find the underling issue?

[safwanrahman]

@arikgelman @DaveRev I have just fixed the issue you have mentioned. Some documentation is needed for sending notification to chrome, will do this shortly.

[safwanrahman]

@arikgelman Can you check the latest master version if its still raising error?

[arikgelman]

@safwanrahman , I am pressing the "Subscribe to Push Messaging" in chrome and I am not getting any request from the browser to approve, I can see in the database the "PushInformation object" and when I am trying to send a test message I am getting this error:
Push failed: <Response [410]>: {"code": 410, "errno": 106, "error": "", "more_info": "http://autopush.readthedocs.io/en/latest/http.html#error-codes", "message": "Request did not validate No such subscription"}

Firefox still working.

[safwanrahman]

@arikgelman I have updated the documentation. Can you please check again according to it?
Please be mentioned that GCM_KEYS are no longer in use.

[arikgelman]

@safwanrahman , Sorry, still not working, now its just hangs when I press the "Subscribe to Push Messaging" and nothing is added to database. This is the error from the Chrome console:
Subscription error. DOMException: Registration failed - missing applicationServerKey, and manifest empty or missing
Firefox still working

[safwanrahman]

Can you please put the browser console output?

[arikgelman]

@safwanrahman

Subscription error. DOMException: Registration failed - missing applicationServerKey, and manifest empty or missing

[safwanrahman]

Can you please uninstall and reinstall directly from github?

[arikgelman]

@safwanrahman , Still not working, same error.

[safwanrahman]

@arikgelman I have made a new release. Can you please check the latest one?

[arikgelman]

@safwanrahman I am getting installation error:

Complete output from command python setup.py egg_info:

[safwanrahman]

@arikgelman What did you run?

[arikgelman]

@safwanrahman : pip install django-webpush.zip

[safwanrahman]

@arikgelman please run pip install -U django-webpush
I do not have a windows machine to test your error! 😢

[arikgelman]

@safwanrahman OK, I found the problem, change in the setup.py file to this:

with open(os.path.join(os.path.dirname(__file__), 'README.rst'), encoding="utf-8") as readme: README = readme.read()

[arikgelman]

@safwanrahman , Sorry, still the same error, I also added manifest.json to my site but still the same error.

[safwanrahman]

@arikgelman Can you please let me know which version of chrome you are using?

[arikgelman]

@safwanrahman Version 65.0.3325.146 (Official Build) (64-bit)

[arikgelman]

It looks like Opera is not working either, Firefox is working on mobile and desktop. Chrome is not working on mobile and desktop.

[arikgelman]

@safwanrahman OK, I was able to fix the registration process in chrome, Now I was able to register with chrome but when I am trying to send a test message I am getting this error:
`
Exception Type: WebPushException at /admin/webpush/pushinformation/
Exception Value: Push failed: <Response [400]>:

<TITLE>UnauthorizedRegistration</TITLE>

UnauthorizedRegistration

Error 400

`

[jamaalscarlett]

Did you forget to include the credentials in the request?

[safwanrahman]

@arikgelman Have you setup WEBPUSH_SETTINGS as mentioned in the doc?

[arikgelman]

Yes

[arikgelman]

@safwanrahman Hi, any idea what could be the problem?

[safwanrahman]

@arikgelman I am actually investigating it. I barely use the test message.
Can you please check from the django shell?

[arikgelman]

@safwanrahman Hi, still the same error:

`
