Description:
This generator compares your existing schema against the
schema declared inside your declare_schema do ... end
declarations in your models.
If the generator finds differences, it will display the
migration it has created, and prompt you for the migration name,
supplying a numbered default name.
The generator is conservative and will prompt you to resolve
any ambiguities.
Example:
$ bundle exec rails generate declare_schema:migration
---------- Up Migration ----------
create_table :users do |t|
t.string :first_name, limit: 50
t.string :last_name, limit: 50
t.datetime :created_at
t.datetime :updated_at
end
----------------------------------
---------- Down Migration --------
drop_table :users
----------------------------------
Migration filename: (spaces will be converted to _) [declare_schema_migration_2]: create users
exists db/migrate
create db/migrate/20091023183838_create_users.rb
Not running migration since --migrate not given. When you are ready, run:
bundle exec rails db:migrate
