I have two models:
class Foo(models.Model):
foo_field = ...
class Bar(models.Model):
foo = models.ForeignKey(Foo, on_delete=models.CASCADE)
bar_field = ...
and I can access all Bar instances related to a Foo with:
Foo.bar_set.all()
Is there a way to change the 'reverse name', like in ManyToManyField, so that I can write:
Foo.bars.all()
?
Speaking of databases, Django simplifies most of the queries you can make while working with databases. One such query is the reverse look; an example is when we have to get all the objects of a table that are referencing a particular record of either the same table or a different model.
The related_name attribute specifies the name of the reverse relation from the User model back to your model. If you don't specify a related_name, Django automatically creates one using the name of your model with the suffix _set.
To handle One-To-Many relationships in Django you need to use ForeignKey . The current structure in your example allows each Dude to have one number, and each number to belong to multiple Dudes (same with Business).
yes, using related_name
class Foo(models.Model):
foo_field = ...
class Bar(models.Model):
foo = models.ForeignKey(Foo, related_name="bars", on_delete=models.CASCADE)
bar_field = ...
