ruby on rails - Best Practice for DB Migrations that Affect Many Tables -

-

say have database of 50 tables. making change wording of 1 of columns relationship affects 20 of tables. how set migration? see @ least 3 possibilities

  1. a separate migration change on every table
  2. a single migration of them
  3. changing initial declaration of creation of tables.

i'm quite confident 3 worst approach because cannot migrate have rebuild entire schema. i'm stuck between 1 , 2. 2 best approach because creating 1 migration 1 change happens affect lot of tables. i'm leaning towards. on other hand, feels messy.

any resources on appreciated well. thanks

it makes more sense go option 2.

say take option 1 , x separate migrations. you'll end x migrations mess database's integrity, you'll have run them (or rollback them if want undo changes). if changes need made together, makes sense put them in same file
