Here's a sample of the kinds of question people seem to often ask about old Rails migrations: - https://stackoverflow.com/questions/20119391/delete-old-migrations-files-in-a-rails-app - https://www.reddit.com/r/rails/comments/4ayosd/compacting_migrations_files_or_delete_them/ - https://stackoverflow.com/questions/4248682/is-it-a-good-idea-to-purge-old-rails-migration-files - https://stackoverflow.com/questions/707013/is-it-a-good-idea-to-collapse-old-rails-migrations - https://stackoverflow.com/questions/1981777/rails-remove-old-models-with-migrations - https://stackoverflow.com/questions/3343534/rebase-rails-migrations-in-a-long-running-project The common theme seems to be: "I've got old migrations, should I keep them around on an old project?". My personal stance is that as long as migrations run and don't take too long do so, you should keep them around since it allows people working on the Rails project with you to seamlessly upgrade their local development database without having to do a `db:drop db:schema:load` and lose all their seed data. While writing down this suggested new section it felt like I was describing a very cumbersome process that could be address with a rake task like: ```bash rails db:migrate:remove VERSION=20121201123456 ``` It rollback to the version just before `20121201123456`, delete the migration file, and run `db:migrate` to get back to the latest migration. This of course doesn't address a situation when someone would want to delete or merge all migrations prior to a certain date, which is addressed by [squasher](https://github.com/jalkoby/squasher). I'm not sure this is something we want to encourage people to do. Although I feel like with more and more production Rails apps over 5-years old, it's definitely a concern we should address.

| | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed in #33203 rails command already looks for, and runs, bin/rails if it is present. We were mixing recommendations within guides and USAGE guidelines, in some files we recommended using rails, in others bin/rails and in some cases we even had both options mixed together.

* Update schema.rb documentation [CI SKIP]Derek Prior2018-04-241-45/+35
| | | | | | | | | | | | | | | | | | | | | The documentation previously claimed that `db/schema.rb` was "the authoritative source for your database schema" while simultaneously also acknowledging that the file is generated. These two statements are incongruous and the guides accurately call out that many database constructs are unsupported by `schema.rb`. This change updates the comment at the top of `schema.rb` to remove the assertion that the file is authoritative. The documentation also previously referred vaguely to "issues" when re-running old migrations. This has been updated slightly to hint at the types of problems that one can encounter with old migrations. In sum, this change attempts to more accurately capture the pros, cons, and shortcomings of the two schema formats in the guides and in the comment at the top of `schema.rb`.

| | | | | | | | | | | | | | | | | | | | | | | | | | Comments are specified in migrations, stored in database itself (in its schema), and dumped into db/schema.rb file. This allows to generate good documentation and explain columns and tables' purpose to everyone from new developers to database administrators. For PostgreSQL and MySQL only. SQLite does not support comments at the moment.

* Use a deliberately-invalid migration version in all doc examplesMatthew Draper2015-12-151-19/+19
| | | | | | | | | | If we use a real version, at best that'll be an onerous update required for each release; at worst, it will encourage users to write new migrations against an older version than they're using. The other option would be to leave these bare, without any version specifier. But as that's just a variant spelling of "4.2", it would seem to raise the same concerns as above.
