"DO_NOTHING" is not defined django
To fix the error "DO_NOTHING is not defined" in Django, you can follow these steps:
- Open the file where the error is occurring. This could be a models.py file or a migration file.
- Look for a field that has a
ForeignKey
orOneToOneField
relationship defined. - In the relationship definition, there should be an
on_delete
parameter specified. This parameter determines what should happen when the referenced object is deleted. - If the
on_delete
parameter is not specified, or if it is set to a value that is not recognized, such asDO_NOTHING
, you will encounter the "DO_NOTHING is not defined" error. - To fix the error, you need to replace
DO_NOTHING
with a validon_delete
option. Django provides several options to choose from, such asCASCADE
,PROTECT
,SET_NULL
, andSET_DEFAULT
, among others. - Choose the appropriate
on_delete
option based on your requirements. For example, if you want to delete the referencing object when the referenced object is deleted, you can useCASCADE
. - Replace
DO_NOTHING
with the chosenon_delete
option in the relationship definition.
By following these steps, you should be able to resolve the "DO_NOTHING is not defined" error in Django.
