Django - annotation produces duplicate joins
The following annotation produces duplicates .annotate( **{ f"{key}_bundle_id": F('item__child_link__parent_item__bundle__id'), f"{key}_bundle_name": F('item__child_link__parent_item__bundle__name') } ) Both of these annotations join across a many to many table to get the id and name of the joined table. I would expect this to produce a join, and select both the id and name from the join. Instead it duplicates the join and selects the id from 1 set and the name from the other. Is there a solution to work around this or do annotations always produce their own joins? Here's the sql it generates: SELECT T8.id as x_axis_bundle_id, T12.name as x_axis_bundle_name .... INNER JOIN "item" ON ("gmdts"."item_id" = "item"."id") INNER JOIN "link" ON ("item"."id" = "link"."child_id") INNER JOIN "item" T8 ON ("link"."parent_id" = T8."id") INNER JOIN "bundle" T9 ON (T8."id" = T9."item_id") INNER JOIN "link" T10 ON ("item"."id" = T10."child_id") INNER JOIN "item" T11 ON (T10."parent_id" = T11."id") INNER JOIN "bundle" T12 ON (T11."id" = T12."item_id") -

Cascade delete of model with GenericForeignKey without using GenericRelation
I'm creating a reusable django app which includes a model with GenericForeignKey which I need to be cascade deleted. This model may be attached to any other. I have no control over target model class as it is outside of the app. This means I can not add GenericRelation field to it and can't force user to add it as target might be in another third-party app. Assuming we have such models (having NO control over Post and PostGroup): class Tag(models.Model): content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() object = GenericForeignKey() class PostGroup(models.Model): title = models.CharField(max_length=255) class Post(models.Model): title = models.CharField(max_length=255) group = models.ForeignKey(PostGroup, on_delete=models.CASCADE) Is there a way to delete Tag in case of PostGroup queryset is being deleted? E.g. not only post_group.delete() but also PostGroup.objects.delete(). -
how can I add a django array element into a js array using an if condition

How can I query data from two tables in Django, when some of the data is conditional
We have multiple data tables, the 'main' one is Player with the primary key Player Name, which is a foreign key to a few other tables, and a foreign key Team Name which is a foreign key to a table called Team, with Team Name being that primary key. We have this query in SQL: SELECT p.TeamName, AVG(b.G) as avg_games_for_team, AVG(b.OPS) FROM Players as p JOIN batter as b ON p.PlayerName = b.PlayerName GROUP BY p.TeamName ORDER BY avg_games_for_team LIMIT 15; And we can't translate this into Django ORM. I know you're supposed to give some of the code you've tried, but we really aren't able to put anything down into paper. The only thing we can get is something like Players.objects.select_related('Teams').get(TeamName).filter(...) using this as a start. We also know to use .annotate() but can't discover where or how.

Database considerations when writing a Django app for personal use only in a local server
I am a Django developer for a startup. The project is about to finish and I will start looking for a new job soon. I would like to use my skills do write a simple app to keep my job search organised and I would like to keep my database running on my localhost. I don't want to spend money and effort hosting the website online as I can simply run it with a local database. The problem is that as I develop my apps I usually nuke my database when some migration didn't go as planned or sometimes when PostgreSQL acts out (as in updates). So I would like to know what are the best options for developing and app with a development database while I have an actual database with valuable data that I don't want to lose. If anybody ever faced this problem I would like to know possible solutions. Thanks! -

Django - best way to manage existing, auto increment fields with existing data?
This is still in dev, so I am relatively flexible in how to approach this. So I'm importing data (via fixtures, the import works fine) from an existing database into a django application. The source data is not uniformed in how it manages ID & primary keys. Some tables use what seems to be an auto-increment (similar to what django would produce by default). Others use some sort of integers. The relationships in the data dump are established based on those fields. Seems I can keep on using auto-increments in all cases. They are conveniently not named uniformly: id, pk, pk_sometablename, etc. The fixtures I use to import look like this (I generated them using a script based on the datadump, so this can be changed if needs be): { "model": "admin_account.client", "pk": "168", "fields": { "pk_client": "168", My django model: class Client(models.Model): pk_client = models.IntegerField(verbose_name='Pk_client', blank=True, null=True) I need to be able to import the data in such a way that this field, the pk_client field is used as the primary key (it can still remain as an auto-increment). So I tried to change to this: class Client(models.Model): pk_client = models.AutoField(primary_key=True, verbose_name="pk_client", default=-9999) However if I try this migration … -

In my app, I have created a context_proccessors.py to show the form to base.html file. I am able to show the form in the base.html file. But the problem I am facing is I have no idea how to save that form data from base.html since there is no view for the base.html. Below is my code: models.py class Posts(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='user_posts') post_pic = models.ImageField(upload_to='post_pic', verbose_name="Image") post_caption = models.TextField(max_length=264, verbose_name="Caption") created_date = models.DateTimeField(auto_now_add=True) edited_date = models.DateTimeField(auto_now=True) def __str__(self): return f"{self.user.username}" forms.py from django import forms from post_app.models import Posts class PostForm(forms.ModelForm): class Meta: model = Posts exclude = ('user',) context_proccessors.py from post_app.forms import PostForm def post_form(request): form = PostForm return { 'post_form': form, } I want the form to be displayed on every page so that the user can submit data from anywhere
