Django errors (can't run the order_id without cause it is a foreign key)

Hello everyone.
I have been following Mosh tutorial videos on django.
Currently on the setting up the database( Generating Dummy Data)
After generating the database and i paste the codes that should be inserted into the database, it keeps showing me an error saying “cannot add or update a child row foreign key.” and i did exactly what he did.

Please what should I do?
