After migrating an external pg db, all my tests failed because of "PG::ForeignKeyViolation"

I updated my app's db from sqlite to an external postgres already populated with tables. Now, when I run bundle exec rake test, I get this error on every test:

ActiveRecord::InvalidForeignKey:         ActiveRecord::InvalidForeignKey: PG::ForeignKeyViolation: ERROR:  update or delete on table "lessons_lesson" violates foreign key constraint "lessons_word_lesson_id_567928f32e967ac_fk_lessons_lesson_id" on table "lessons_word"
        DETAIL:  Key (id)=(1) is still referenced from table "lessons_word".
        : DELETE FROM "lessons_lesson"

I couldn't fix this simply by updating all the models to the table_name they are interacting with...

establish_connection :developmenet
self.table_name = 'lessons_lesson'

I suspect this has something to do with postgres??

did you notice your TYPO loool 'establish_connection :developmenet' rather than 'development'

Oops, I typed it wrong here, but there is no typo in the actual code.
