Django difficulty ORM annotate/aggregate query suggesion
I'm trying to come up with code for a fairly difficult query (for me at least). I'm not sure it's possible to do in the ORM. If not, dropping into SQL is fine, but I can't quite wrap my head around that either. Say I have these two models: class BlogArticle(models.Model): published_date = models.DateField() sentiment_score = models.DecimalField() Publication(models.Model): articles = models.ForeignKey() In the view, I want to accept Publication ids from query params. I then want to end up with a dictionary with a key for each publication, containing a value of a list of key-value pairs. The key will be a day (using TruncDay('publication_date')), and the value will be the average sentiment_score for that day. For example: { 'Some publication': [ '2021 01 31': 0.23, '2021 01 30': 0.31, ... ], 'Another publication': ... } The closest I've gotten is this: ids = request.GET.getlist('id', []) blog_articles = BlogArticle.objects.filter(publication__id__in=ids) blog_articles = self.perform_other_blog_filters(blog_articles) return blog_articles .annotate(day=TruncDay('publish_date')) .order_by('day').values('day').annotate(Avg('sentiment_score')) This doesn't work, because it will give the average per day for blog articles from all Publication ids passed in, whereas I need them separated by Publication. The kicker here is I need to start from a list of blog articles, not publications, because … -

Ajax/Axios cookies not being set, but still being included in following requests

How to display list items in descending order in django?
I've created a website that streams cartoons. On the first page, the user gets to see the entire list of cartoons. When clicked, a page showing the details of the cartoon as well its corresponding seasons loads. When a specific season is clicked. It shows the list of episodes that season has. Now what happens is that it displays the episodes normally, however, it shows them in a jumbled format. I want to show it in descending order. How am I supposed to go about doing that? Here are my files.

Changing db_table on Django doesn't work after migrations, and adding a user (AbstractUser) foreign key breaks __str__()
This is a 2 problem post, which i suspect are somehow connected. My posts app on Django doesn't migrate properly (I think), and adding the 'author' (Users AbstractUser model) breaks my code with the error: str returned non-string (type tuple) whenever I try to add a row. I changed the name of the table using db_table (so it will change Postss to Posts on the admin page) and added an output to the __str__ function, I tried a few variations of output for the str function but non of them worked. I even tried to comment it out. and still. no changes in the table name or the error. I tried changing my str functions a few times and got the same result. when deleting the str function, I still get that same result. I have a few wild guesses about this situation: it might not work with an abstract users class for some reason, and do not know to to work around this and why this happens at all. (removeing the author=... row resolves this problem but doesn't change the table name, but I do need the user fk there). it might not be migrating properly due to my … -
Django: Include template with constructed name if available
I have a one template say: default_form.html which receives in its context a variable, say variant. I can of course render the contents of the variable with {{ variant }} And here: https://stackoverflow.com/a/28076380/4002633 I see a wonderful way to load a template if it exists. It works nicely if I have a template called variant as follows: {% try_include variant %} But I am hoping to go one step further. I would like to use a constructed template name, in the example above and include if it exists a template named default_form_variant.html. I imagine something like this: {% try_include "default_form_{{variant}}.html" %} but even more general rather than encoding the current template's name, getting that, if possible, from the context itself or in a custom tag from the parser. I am struggling to see how and where in the custom tag definition I'd have access to three things at once: The name of the current template: default_form.html in this case. The argument to the tag: variant in this case The ability to construct a template name from the first two (easy enough with os.path) and inject it into the do_include handler. -
