So I have a class called 'Racks' which is a sub class of other super classes. One of the attributes which was previously inherited (but has now been deleted) was the 'make' attribute which had a not null constraint.
Since deleting this attribute I have attempted to create a card within my 'Racks' class, unfortunately I am receiving the following error:
SQL error: ERROR: new row for relation "rack" violates check constraint "_NotNull_make"
Is there any way for me to get around this? Other attributes which have been deleted are still showing within the database when I select the table.
Thanks,
Jamie
