Rails 3 plugin - Generate a custom migration file
- by moshimoshi
Hi,
On this article http://www.themodestrubyist.com/2010/03/16/rails-3-plugins---part-3---rake-tasks-generators-initializers-oh-my/ we can see the following codes which allow to invoke a migration file:
class ActsAsTaggableOnMigrationGenerator < Rails::Generators::Base
invoke "migration", %(add_fields_to_tags name:string label:string)
end
The command looks like:
$ rails generate acts_as_taggable_on User
invoke migration
invoke active_record
create db/migrate/20100529220831_user.rb
error "add_fields_to_tags name:string label:string" [not found]
I don't understand why I get this error... and I have 2 questions about:
1/ How can I do to customize the name of the generated file? Just like: 20100529220831_add_tag_field_to_users.rb.
2/ How can I pass in some args such as:
$ rails generate acts_as_taggable_on User tag1 tag2 tag2
in order to customize the generating file such as tag1:string tag2:string tag3:string...
Many thanks!
