How to delete a record in Django models?

Question

I want to delete a particular record. Such as

delete from table_name where id = 1; 

How can I do this in a django model?

Answer 1

There are a couple of ways:

To delete it directly:

SomeModel.objects.filter(id=id).delete() 

To delete it from an instance:

instance = SomeModel.objects.get(id=id) instance.delete() 

Answer 2

MyModel.objects.get(pk=1).delete() 

this will raise exception if the object with specified primary key doesn't exist because at first it tries to retrieve the specified object.

MyModel.objects.filter(pk=1).delete() 

this wont raise exception if the object with specified primary key doesn't exist and it directly produces the query

DELETE FROM my_models where id=1
