Django render page with context does not work
I like to re-render my page, after a document was uploaded using Djanog. I like to change context['FileName'] = 'Test' to context['FileName'] = 'Test2' in the HTML page.

Python Websockets handles one time use only

Django create user Direct assignment to the forward side of a many-to-many set is prohibited. Use groups.set() instead

Cross-database relationships in Django with MySQL
Is there a primer on how to develop systems that segregate auth information from other information across multiple databases using Django without foregoing FK to User in another db? Django doesn’t currently provide any support for foreign key or many-to-many relationships spanning multiple databases. If you have used a router to partition models to different databases, any foreign key and many-to-many relationships defined by those models must be internal to a single database.

Merging Django-CMS Edit and Publish Mode created two different Database entries with the same values
My CTO asked me to fix an "issue." Apparently, whenever I add any plugin in the locally run DRF-based Django CMS project, it creates two database entries. One for edit mode, and the other when I hit publish. My CTO asked to find if there were any way to dynamically merge the edit mode entry with the merge mode and vice versa when switching between those modes. Our website is very heavy. But is doing this even necessary for Django-CMS? Here is the model.py code for an example plugin. Models.py: class TechnologyVideo(ck_CMSPlugin): Video_thumb = models.ImageField(upload_to="technology_video", null=True, blank=True) video_url = models.URLField(help_text='Please enter your video url', validators=[URLValidator], null=True) # video_title = models.CharField(max_length=100, blank=True, null=True, ) # video_description = HTMLField(null=True, blank=True, configuration="VIDEO_POST_TEXT_CKEDITOR") class Meta: verbose_name = "Technology Video Model" def __unicode__(self): return f'{self.Video_thumb}' cms_plugins.py: class TechnologyVideoPlugin(CMSPluginBase): model = TechnologyVideo name = 'Technology Video Plugin' render_template = 'technology_video.html' def render(self, context, instance, placeholder): context.update({ 'Video_thumb': instance.Video_thumb, 'video_url': instance.video_url, }) context = super(TechnologyVideoPlugin, self).render(context, instance, placeholder) return context plugin_pool.register_plugin(TechnologyVideoPlugin) -
How to solve the problem of widgets.py on Heroku?

Calling Channels AsyncWebCoscketConsumer function from Signals Receiver doesn't work
Firstly, here's the code. I have checked it now I don't know how many times for any errors, and debugged step by step to find out why the function isn't called. # signals.py @receiver(post_save, sender=Ticket) def new_ticket(sender, instance, created, **kwargs): print("in receiver") if created: print("in created") channel_layer = get_channel_layer() print(channel_layer) async_to_sync(channel_layer.group_send( 'tickets_updates_group', { 'type': 'new_ticket', 'subject': "from receiver" })) print("after async_to_sync") All the print statements are always being called. # consumers.py class Tickets(AsyncWebsocketConsumer): async def connect(self): await self.channel_layer.group_add('tickets_updates_group', self.channel_name) await self.accept() async def disconnect(self, close_code): await self.channel_layer.group_discard('tickets_updates_group', self.channel_name) await self.close() async def new_ticket(self, event): print('in consumer.new_ticket') subject = event['subject'] print("subject: " + subject) await self.send(text_data=json.dumps({ 'subject': subject })) print("after send") Here, the new_ticket function is never being called, none of the print statements are being executed and my webpage isn't updated (as opposed to putting the group_send code in the connect funciton of the consumer class.

Django suddenly raises `OSError: [Errno 22] Invalid argument` and dev server doesn't work anymore
I made some changes to a html file and suddenly my django app stopped loading with the dev server returning OSError: [Errno 22] Invalid argument. I never had such situation in years of Django coding and don't know how to further investigate / fix this? I shut all sessions/tabs etc. and restarted the dev server without success. This is what I get when starting dev server: Watching for file changes with StatReloader Performing system checks... System check identified no issues (0 silenced).

Reverse resolution of URLs in Django with multiple url parameters
In my blog app I need to show articles based on the url: app_name = 'blog_app' urlpatterns = [ path('<int:user_id>/<int:year>/<int:month>', views.IndexView.as_view(), name='index'), path('<int:user_id>/<int:year>/<int:month>/<int:article_id>', views.DetailView.as_view(), name='detail'), ] The structure of the project is: myblog points to portal (for login); after login portal points to blog_app (which contains the articles list). So the steps to show articles are: mysite_index --> portal_login --> blog_app_index In portal app, after login, using a button I want to go to the index view of blog_app. So I need to specify all url parameters, and I'm trying to do it in this way: {% if user.is_authenticated %} <a href=" {% url 'blog_app:index' user_id = user.id year = {% now "Y" %} month = {% now "m" %} %} "> <button class="btn btn-secondary" type="button">Go</button> </a> {% endif %} I don't know why the URL becomes: http://127.0.0.1:8000/portal/%7B%25%20url%20'blog_app:index'%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20user_id%20%3D%20user.id%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20year%20%3D%202022%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20month%20%3D%2008%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%25%7D What I'm doing wrong? How I should do this type of reversing?
