How to query directly the table created by Django for a ManyToMany relation?

问题

I have a model MyModel2 with a ManyToManyField related to another model MyModel1.

How can I get the pairs mymodel1.id, mymodel2.id, as represented in the table Django create for this relation? Do I have to do a raw SQL query on this table or is it possible through the object managers of this models?

class MyModel1(models.Model):
    name = models.CharField(max_length=50)


class MyModel2(models.Model):
    name = models.CharField(max_length=50)
    mymodel1 = models.ManyToManyField(MyModel1)

回答1:

This is the many to many field instance:

MyModel2.mymodel1

This is the intermediary table model:

MyModel2.mymodel1.through

This is the intermediary model manager:

MyModel2.mymodel1.through.objects

This returns a queryset for all intermediary models:

MyModel2.mymodel1.through.objects.all()

This part of django docs talk about through. You can make a through model yourself, else it is automatically generated.
