Filter those rows that have most rows in in a related table, while also doing a distinct query
I have a Media model that has a many-to-many relationship to Artist (one Media can have many artists and one Artist can belong to many media). Also each user can rate each Media through a relational table named UserMedia, one Media can have multiple UserMedia. I want to do a query where I order by most ratings (UserMedia), while also filter the queryset for distinct Artist, such that each artist appears only once in the queryset and that Media is returned with the most UserMedia related rows (or counts). I can do the two things separately, order by most counts or do a distinct artists filter. Here's the query that I have right now: distinct_artists = models.Media.objects.distinct("artists__id") queryset = ( models.Media.objects.annotate( count_ratings=Count("usermedia"), ).filter( count_ratings__gte=F("count_ratings") ) .order_by("-count_ratings") .filter( id__in=distinct_artists ) ) The resultset returns distinct Artist, but not the Media with the most counts of UserMedia for this artist. -
Django group by and order by
I have comment table with following fields. Here, first row means, 3rd comment in the database belongs to post 1. Second and third row means, 3rd and 4th comments belongs to post 1 and they are also replies to the 2nd comment and so on. id post_id comment_id date 2 1 ... 3 1 2 ... 4 1 2 ... 5 1 ... 6 1 5 ... I would like to do a django group by query so such that, to get all the comments of post 1 and group them by the replies to a comment. So I would expect groups like this group1: comment2: comment3,4 group2: comment5: comment6 The group query should also be ordered by date field. How can I do this? -
Add a new item to a related fields within a form
I want a user to be able to select from an existing list of options. If the option is not within the ones already in the database, though, they need to be able to add a new item, while remaining on the main form, because after having added the new item they need to be able to save the main form I was using the JQuery library select2, which allows a tags:True option, thanks to which users can add a new item to a list if not present. Nevertheless, Django validates that field and if it finds an item which is not in the database is raises an error. My initial plan was that of capturing the new value in the view and then (saving first the form with commit=False), if it was not in the database, save it. But this is not doable without forcing Django not to validate the field, which I haven't managed to do. Another option, which I'm currently investigating, is that of adding a modal pop-up containing the sub-form. Of course I'd like to avoid opening the sub-form in another page, which would work but would be quite non-user-friendly. models.py: class Venue(models.Model): venue_name = models.CharField(max_length=30) … -

I want my Django program to check if my my entry is authorized and if it's either Manual or Auto. If it is authorized, then I want to prevent it from being deleted so basically disable the delete option for it and if it is Automatic, I want to prevent it from being edited when I click on the model object in the Django admin.

Django Wagtail Deployment Static File Server
After deployment today, for some reason, the project no longer shows style from items that would have been collected during the collectstatic process. I have full access to the files from any browser. I have checked all permissions. I have browsed to the site from the development server, and other machines to eliminate software\font possibilities. No idea what's going on here. I serve the files from a different server. Other django projects are unaffected. No other django projects use anything like wagtail though.
