Description:
|
||||
The migration generator creates a stub for a new database migration.
|
||||
|
||||
The generator takes a migration name as its argument. The migration name may be
|
||||
given in CamelCase or under_score.
|
||||
|
||||
The generator creates a migration class in db/migrate prefixed by its number
|
||||
in the queue.
|
||||
|
||||
Example:
|
||||
./script/generate migration AddSslFlag
|
||||
|
||||
With 4 existing migrations, this will create an AddSslFlag migration in the
|
||||
file db/migrate/5_add_ssl_flag.rb
