Python channel too. Are you new to Django?
I had a error in my project, as I am a beginner with dev Django, I went to read the manual. But I remained a little confused. In my case I have the models called Clients and Hosts.
Every Host belongs to a Client, so I added the id_client field as a foreign key, in the Host table, in the templates when I have to access the client name through the Host table do so for example: {{host.id_client.name}}.
But when I was learning and trying to implement CRUD + AJAX on my project, when trying to create a new Hosts model record, I had to use id_client_id, for function "create ()" ...
In the Models documentation, I found the paragraph "Database Representation" that says Django adds "_id", but would you like to understand if this is editable? Or should you rename the column FK?
My models:
class Clients(models.Model):
id_client = models.BigIntegerField(primary_key=True, blank=True)
...
class Hosts(models.Model):
id_host = models.BigIntegerField(primary_key=True)
id_client = models.ForeignKey('Clients', models.DO_NOTHING, db_column='id_client', related_name='host_client_id')
...
id_client_id=id_client,
<others fields>
)

I am using Django Rest Framework and have a model with a timestamp field that I want to group by. The outcome I would like is to have something like {tournament_count: 2, start_date: datetime object, tournaments: [{...tournaments model representations}]} I currently have a queryset returning the tournament_count and start_date but now I want to drop in the actual tournaments as well.
queryset.annotate(
start_date=Trunc("time_stamp", "day", output_field=DateTimeField())
)
.values("start_date")
.annotate(tournament_count=Count("id")).order_by()I can't figure out a solution that will work well and scale well. Any thoughts?
