Sending message and notification using Django channels
I am trying to implement a messaging system with live notification so that when a user is chatting with userA and userB messages the user it will update the chat messages live and it will update the user's contact list. I have two consumers, one is ChatConsumer, and another one is the UserChatNotificationConsumer which the latter is a connection for each user and server to a notification to them. And every user channel has a unique id (channel name). inside my ChatConsumer, I have a new_message() function which sends a new message from one user to another user in a private chat. After creating a message object in the new_message() function, I have two methods one which sends the message and another which sends the notification: def new_message(self, data): #create the message and other stuff. await self.send_chat_message_notification_user2(content) await self.send_chat_message(content) And my method for sending a notification to user is: async def send_chat_message_notification_user2(self, message): layer = get_channel_layer() await selg.channel_layer.group_send( self.user2_notification_layer, { 'type':'chat_message', 'message':message } ) Which self.user2_notification_layer is a string id of the second user in the chat notification channel. My issue is that the sockets are being connected successfully and I can see the CONNECT and HANDSHAKE process. however, after … -

Django - "Foreign key constraint is incorrectly formed"
I'm trying to add a new model to my database, but every time i create it, i get the following error: "Foreign key constraint is incorrectly formed" This happens both if i try from MySQL and Django. Here are my models: class MainApiKeys(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) key_name = models.CharField(max_length=20) public_key = models.CharField(max_length=100, blank=True, null=True) secret = models.CharField(max_length=100, blank=True, null=True) def save(self): # ALL the signature super(MainApiKeys, self).save() class Selected_key(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) used = models.ForeignKey(MainApiKeys, on_delete=models.DO_NOTHING) def save(self): # ALL the signature super(Selected_key, self).save() If i create the same table from MySQL i'll still get the error CREATE TABLE main_selected_key( user_id INT NOT NULL, used INT NOT NULL, FOREIGN KEY (user_id) REFERENCES auth_user(id) ON DELETE CASCADE, FOREIGN KEY (used) REFERENCES main_api_keys(id) ON DELETE CASCADE) The problem is not with the Foreign Key to User, i'm sure it's the second second key because if i remove that one my code will run just fine.

To my surprise, the following lines pass for a value that is an email address, such as test@example.org: url = 'test@example.org' URLValidator()(url) field = URLField() field.clean(url) Where I would have expected a ValidationError to be raised. Why are email addresses considered valid URLs? And what can I do to accept only domain-like strings other than making my own regex? -

Creating multiple types users in django rest framework, got an unexpected keyword argument 'last_login'
I am trying to learn Django, and I am creating various cases just to exercise and hopefully learn something new. Suppose that I am trying to create different users and assign different permissions latter, but first lets try to create them first.

Django: Javascript is not being imported to global functions
I'm developed a webapp using Django and all works fine. Now I wanted to add a Webseit Tour guide and im using https://github.com/iamdanfox/anno.js. Now to my problem: I downloaded all the files i need and added the files to my static files. I'm importing the js files in my HTML as follows: home.html / Local <script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script> <script src="{% static 'main/js/tour/anno.js' %} type="text/javascript""></script> <script src="{% static 'main/js/tour/jquery.scrollintoview.js' %}" type="text/javascript"></script> The javascript files are unedited and saved in the static files that are written using jquery: https://github.com/iamdanfox/anno.js/blob/gh-pages/dist/anno.js https://github.com/iamdanfox/anno.js/blob/gh-pages/bower_components/scrollintoview/jquery.scrollintoview.js If I'm on my Local machine then my file is imported and everything works as expected.

PKCE Parameters for Snapchat
I'm attempting to write a django-allauth Provider for Snapchat and I'm stuck at a road block. Snapchat requires PKCE parameters. I first changed the AUTH_PARAMS. 'AUTH_PARAMS': { 'code_challenge': 'state', 'code_challenge_method': "S256" } This has only resulted in invalid responses from the Snapchat API upon Access_Token Request, after I have the code response. This error the first error I got. {'error': 'invalid_request', 'error_description': 'Invalid code_verifier length.', 'state': ''} After overriding the SocialLogin.stash_state I receive this error. {'error': 'invalid_grant', 'error_description': 'Invalid code_verifier.', 'state': ''} From what I can dig through the code of all auth I can't find anything in the codebase on the PKCE parameters or base64 Url SHA256 encoding. I'm willing to implement the solution but I'm stuck finding where to subclass the state parameters then match it after. There are some issues around the Snapchat Docs with this as well. https://gist.github.com/CisarJosh/778485dc31d9f268da0339f715ab86fd This is a gist with some of my attempt.
