Add multiple category for one post (drf+React)
I have a blog website built with Django and React. I'm currently working on adding a new blog post feature, and I want to allow users to select one or multiple categories for their blog post.

Django first() for every item
Suppose I have a model EventParticipant, which stores participant data for a given Event. Now I want to retrieve the next event participance for a list of users. The following: EventParticipance.objects.filter(user__in=userlist, start__gte=timezone.now()).order_by(start) would give me all event participances for all users in userlist that start in the future. However, I only want the first one for each user. In Postgres, this could be achieved (I think) by this: EventParticipance.objects.filter(user__in=userlist, start__gte=timezone.now()).order_by(start).distinct('user'). However, this does not work for sqlite or mysql. Obviously, as shown here, this would work, but I suppose it'd be very slow: next_occurrence_ids = [] for user in userlist: id = EventParticipant.objects.filter(user=user, .....).order_by(start).values('id').first() next_occurrence_ids.append(id) return EventParticipant.objects.filter(id__in=next_occurrence_ids Is there any other strategy I could employ? -

Modifying DJANGO_SETTINGS_MODULE in environment variables
I've come across a very dumb yet irritating problem when running my Django server. When running the server it says: ModuleNotFoundError: No module named 'apolo_client.setting' I don't know where in hell I've set this variable to apolo_client.setting. Obviously it's supposed to be "settings" with as s at the end. I tried manually setting the variable in windows and even in python itself, but it doesn't work. I tried retrieving the variable in init.py file in django's conf folder and it says apolo_client.setting! However running os.environ anywhere else in windows gives the current output. Is there a way I could reset the value or maybe search for the bit where it's being set the wrong valule? -

How to get the "overall" counter of an object in a group in a Django template?
I'm using Django's regroup template tag to group a series of objects. Let's say these are the objects: cities = [ {"name": "Mumbai", "population": "19,000,000", "country": "India"}, {"name": "Calcutta", "population": "15,000,000", "country": "India"}, {"name": "New York", "population": "20,000,000", "country": "USA"}, {"name": "Chicago", "population": "7,000,000", "country": "USA"}, {"name": "Tokyo", "population": "33,000,000", "country": "Japan"}, ] In my template, I'm grouping them like this: {% regroup cities by country as country_list %} <ul> {% for country in country_list %} <li>{{ country.grouper }} <ul> {% for city in country.list %} <li>{{ city.name }}: {{ city.population }}</li> {% endfor %} </ul> </li> {% endfor %} </ul> Which results in India Mumbai: 19,000,000 Calcutta: 15,000,000 USA New York: 20,000,000 Chicago: 7,000,000 Japan Tokyo: 33,000,000 I would like to show an "overall" index for each object, so that it looks like this: India 1: Mumbai: 19,000,000 2: Calcutta: 15,000,000 USA 3: New York: 20,000,000 4: Chicago: 7,000,000 Japan 5: Tokyo: 33,000,000 I'm not asking for an HTML solution; my use case is a series of grouped questions and I would like to add a question counter. Is there a way to do this in the template, or should I write the necessary code in my view? -

Django ORM, How to join a dropped table, with multiple conditions
class Post(Common): author = models.ForeignKey(User, on_delete=models.CASCADE) content = models.TextField() class Comment(Common): post = models.ForeignKey(Post, on_delete=models.CASCADE) author = models.ForeignKey(User, on_delete=models.CASCADE) comment = models.TextField() class Test(Common): post = models.ForeignKey(Post, on_delete=models.CASCADE) tester = models.ForeignKey(User, on_delete=models.CASCADE) category = models.ForeignKey(Category) class Category(Common): pass I want to find a query (Inner JOIN test ON Test.post _id = Comment.post _id AND Test.tester_id = Comment.author_id) to specify two conditions for the join syntax when executing the query based on the following Comment table, but I leave a question because it is hard to find.
