Pass in dynamic href using Django include template tag AND url tag
I'm trying to reuse a component and invoke it multiple times using the include tag. But when I want to pass in a url, I can't figure out the syntax. Usually it would be something like: <a href="{% url 'slug' %}">{{link_title}}</a> But as I'm already using an include, I want to do something equivalent to: # parent template: {% include 'my-template.html' with slug='someslug' link_title='My Link Title' %} # include template: <a href="{% url '{{slug}}' %}">{{link_title}}</a> I currently get django.urls.exceptions.NoReverseMatch from this code -
nginx+uwsgi stops responding after auto reload
I have a docker container based off Alpine 3.16 It runs nginx/uwsgi with supervisord for a django based app. This Dockerfile has been pretty much the same for several years now.

How to create a django generic relation to the same model like foreignkey to self
I am building a comment model which i made generic using the django recommended way like so class GenericRelationship(models.Model): content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey() date_created = models.DateTimeField(default=timezone.now) class Meta: abstract = True class Comment(GenericRelationship): created_by = models.ForeignKey( "account.User", on_delete=models.CASCADE, related_name="comments", related_query_name="comment", ) mentions = models.ManyToManyField( "account.User", related_name="mentions", related_query_name="mention" ) content = QuillField() text_content = models.TextField() likes = GenericRelation(Liked, related_query_name="comment") class Meta: ordering = ["-date_created"] indexes = [ models.Index(fields=["content_type", "object_id"]), ] def __str__(self): return self.created_by.username but in my case a comment can also have comments and i want a reverse relationship(related_query_name) with itself and wont be able to refer to the Comment class like so class Comment(GenericRelationship): ... comments = GenericRelation(Comment, related_query_name="comment") i dont know if i could use a string with self inplace of concrete class i tried using the self but i dont know if its correct cause no real migrations can be made since it's just a reverse relationship: therefore i wont be able to see errors -

How to debug a dockerized django in Visual Studio Code?

Inertia Link not redirecting on click (this.resolveComponent is not a function)
I'm trying to get Django, Inertia and Vue running. I followed this doc (including the referred ones inside that): https://pypi.org/project/inertia-django/ While it works basically (the Vue pages/components render, pages load), I can't use the <Link> component. It renders and shows the correct destination on hovering, but when you click on it, the console shows Uncaught (in promise) TypeError: this.resolveComponent is not a function and it's not redirecting. Although it's changing the page, I can see the corresponding get request in the django server console.

Django: Internal error popped in the first page of list view but normal in other pages
My project has an Order model and a corresponding ListView integrated with a Paginator. I run the code successfully in local development. There is no problem rendering the first and other pages of orders. Also, even after I deployed my project on Heroku, it rendered perfectly. However, the ListView now popped out internal error when I was viewing the first page but no problem at all in case of other pages (e.g page 2, 3 etc). Having checked all the codes in the template, view and model, I still couldn't find the problem. Any insights on this please? What other part am I missing? Thank you. -
Django duplicate column name after dropping and re-creating table
I'm new to Django and am working on my first project. I have multiple tables in the project (I'm using the default sqlite3). One of the tables 'C' is empty. All of the other tables have already been populated with data. Among them table 'M' has a foreign key that is linking it to C's id field (c_id). At some point I changed the max_length of C's id field (c_id) from 5 to 4. I run migrations after that and got an error: django.db.utils.IntegrityError: The row in table 'myapp_M' with primary key '00001' has an invalid foreign key: myapp_M.c_id contains a value '' that does not have a corresponding value in myapp_C.c_id. the field 'c' in 'M' table that is a foreign key has blank=True. I tried adding null=True and running migrations again but it did not help. I decided that maybe dropping the C table, since it's still empty, and creating it again might solve the problem. I have dropped it manually using SQL DROP TABLE, and then used this tutorial to re-create it: https://techstream.org/Bits/Recover-dropped-table-in-Django When I'm running the migrations I am getting the error: django.db.utils.OperationalError: duplicate column name: c_id (which is the first column defined in my model) … -

Test email does not arrive in mail.outbox when sent by Django-RQ worker
I've set up a test within Django that sends an email, in the background, using Django-RQ. I call the code that enqueues the send_email task, then, I get the django-rq worker, and call .work(), with burst=True. In my console, I can see the django-rq worker picking up the job, and confirming that it's been processed successfully. However, the email never arrives in Django's test mail.outbox.

Django shipping method
I have a question about shipping in django. I would like to automate shipping so that automatically when the courier delivers the package the status in the database changes to delivered, etc.... Someone could direct me to some reading on how to do this. Or is it a good standard to just make the shipments in django-oscar and give an admin-panel that will quite transparently change them non-automatically? Or is it standard to capture emails and pull the data you need from them and based on that make a django-celery-task that will do that? -
