Websocket server is part of Django Code for provider is mentioned below late final WebSocketChannel _fpdSockets; Map _webSocketMessages = {}; Map get webSocketMessages { return _webSocketMessages; } WebSocketStreamProvider() : _fpdSockets = IOWebSocketChannel.connect( Uri.parse('ws://127.0.0.1:8000/ws/socket-server/'), ); Stream<Map<String, dynamic>> get dataStream => _fpdSockets.stream .asBroadcastStream() .map<Map<String, dynamic>>((value) => (jsonDecode(value))); void sendDataToServer(dataToServer) { print("Sending Data"); _fpdSockets.sink.add( jsonEncode(dataToServer), ); } void closeConnection() { _fpdSockets.sink.close(); } handleMessages(data) { print(data); _webSocketMessages = data; // notifyListeners(); } } -

Django Model Exception on Pre-existent Database: Cannot resolve keyword 'user' into field. Choices are: organization_id
I'm currently building Django model classes for an already existing database. We have three tables: Organization, User, and UserOrganizationMap. This is because there is a Many-to-Many relationship between the tables Organization and User (a user can belong to multiple organizations and an organization has multiple users). I had to explicitly create the UserOrganizationMap model class since it exists in the database already and I cannot use the one that would be created by Django.

Stripe; Webhook that triggers when the current subscription gets ended (not cancelled)
I know that there is a webhook type customer.subscription.deleted that gets triggered when a user cancels the subscription (that is they don't want the subscription to be auto-renewed after it ends) so at this webhook event, we just update the users subscription state to cancel but they still have the subscription active (and that is expected) but is there any webhook event that gets triggered when the subscription ends or we have to do that manually? I saw this webhook event but i'm not sure if this is the one I'm searching for subscription_schedule.completed Any guidance would be helpful, thank you :) -

It doesn't look very pretty though. What I want to do is to replace my form in customer_register.html with new form in which I wouldn't use widget_tweaks but just html. -
Django media url from model
I'm working on a simple blog, I have this model for the blog post: class BlogPost(models.Model): title = models.CharField(max_length=150, unique=True) body = models.TextField() cover_image = models.ImageField(upload_to='blogposts/') created_on = models.DateTimeField(auto_now_add=True) modified = models.DateTimeField(auto_now=True) category = models.ManyToManyField('PostCategory', related_name='posts') slug = models.SlugField(null=True, unique=True) def __str__(self): return self.title def get_absolute_url(self): return reverse("blog_detail", kwargs={"slug": self.slug}) In the settings file, I have the following configuration for static and media files: STATIC_URL = '/static/' MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') STATIC_ROOT = os.path.join(BASE_DIR, 'static/') I'm creating the blog models and views in a separate app I named "blog" I'm using a Django classed-based list view to display the posts on the page: class BlogListView(ListView): model = BlogPost template_name = "blog/blog_list.html" And I have the URL files working just fine: The problem is in displaying it in my template view, primarily for the post's cover image: {% for post in object_list %} <!-- Single Blog Item --> <div class="single-blog-item style-2 d-flex flex-wrap align-items-center mb-50"> <!-- Blog Thumbnail --> <div class="blog-thumbnail"> <a href="{{ post.get_absolute_url }}"> <img src="{{ post.cover_image }}" alt=""> </a> </div> <!-- Blog Content --> <div class="blog-content"> <a href="{{ post.get_absolute_url }}" class="post-title">{{ post.title }}</a> <p>We'll come back to this...</p> <div class="post-meta"> <a href="#"><i class="icon_clock_alt"></i> {{ post.created_on }}</a> … -
Django - One to One field bug not saving data without error
I am currently experiencing an issue with a one-to-one field in Django where the data was not stored after assigning value and save call is successful without any error. class Model1(models.Model): field1 = models.OneToOneField(Model1, on_delete=models.SET_NULL, null=True, blank=True, default=None) # Some other fields here def link_item(self, model2_id): field1 = Model2.objects.get(id=model2_id) self.field1 = field1 self.save() When I use the link_item of the model from the python shell it was updating the field but when it was used on the normal process the save call is successfully called but when I checked the value again in the shell it didn't update the field1. I have almost 10 million rows of data for Model1 and Model2, I'm not sure if it related to the issue but maybe it could help.
