get a list of ids from queryset django

To get a list of IDs from a queryset in Django, you can follow these steps:

  1. First, define your queryset. This can be done by using Django's ORM (Object-Relational Mapping) to query the database for the desired data. For example, you might have a model called "MyModel" and want to retrieve all instances of it:
my_queryset = MyModel.objects.all()
  1. Next, use the values_list() method on the queryset to retrieve a list of specific fields from the model. In this case, you want to retrieve the IDs, so you can specify the field name as an argument to values_list():
id_list = my_queryset.values_list('id', flat=True)

The values_list() method returns a list of tuples, with each tuple representing a single instance of the model. By specifying 'id' as the argument, you are telling Django to only retrieve the IDs. The flat=True argument flattens the returned list, so you get a single list of IDs instead of a list of tuples.

  1. Finally, if needed, you can convert the list of IDs to a regular Python list using the list() function:
id_list = list(id_list)

This step is optional, as the values_list() method already returns a list-like object. However, if you specifically need a standard Python list, you can convert it using the list() function.

That's it! Following these steps will give you a list of IDs from your queryset in Django.
