That would then generate a file in db/migrate that…would be our migration, and it would call it create_subjects.…Plural, there would be a class name of that migration called create subjects.…Again, also plural.…And it would inherit from ActiveRecord migration.…It would populate it with code for creating…the table subjects and dropping the table subjects.…Or if it gave us that change method, it might only have the create table subjects.…
