I was having a similar error yesterday, after adding another field to my
model I ran the migrations and was giving me an error as if I was
overwriting another field.
After a time searching for an answer for me ,the solution was (and I know
this is not a good practice) delete all the migration files and run the
migrations again.
Then again, If someone knows a better solution...
