Description:
This generator compares your existing schema against the
schema declared inside your fields declarations in your
models.
If the generator finds differences, it will display the
migration it has created, and ask you if you wish to
[g]enerate migration, generate and [m]igrate now or [c]ancel?
Enter "g" to just generate the migration but do not run it.
Enter "m" to generate the migration and run it, or press "c"
to do nothing.
The generator will then prompt you for the migration name,
supplying a numbered default name.
The generator is conservative and will prompt you to resolve
any ambiguities.
Examples:
$ rails generate declare_schema:migration
---------- Up Migration ----------
create_table :foos do |t|
t.datetime :created_at
t.datetime :updated_at
end
----------------------------------
---------- Down Migration --------
drop_table :foos
----------------------------------
What now: [g]enerate migration, generate and [m]igrate now or [c]ancel? m
Migration filename:
(you can type spaces instead of '_' -- every little helps)
Filename [declare_schema_migration_2]: create_foo
exists db/migrate
create db/migrate/20091023183838_create_foo.rb
