How can I temporarily disable a foreign key constraint in MySQL?

Is it possible to temporarily disable constraints in MySQL? I have two Django models, each with a foreign key to the other one. Deleting instances of a model returns an error because of the foreign key constraint: cursor.execute("DELETE FROM myapp_item WHERE n = %s", n) transaction.commit_unless_managed() #a foreign key constraint fails here cursor.execute("DELETE FROM myapp_style WHERE n = %s", n) transaction.commit_unless_managed() Is it possible to temporarily disable constraints and delete anyway?
