Description
After creating a migration, via makemigrations
, I attempted to run sqlmigrate
, but received the following error. I have 3 migrations using the object referenced. It would be helpful to add the exact migration operation in the traceback. I think the migration traceback should, also, show the model/table and column that is part of the error.

Note: I have posted this error to the CleanerVersion team due to the exact error.
