rails generate - "Could not find generator"

I am following the Ruby on Rails tutorial by Michael Hartl. In section 6.3.1, I am trying to generate a migration file to add a Password field to my user model. Here is the code that I run:

rails generate add_passsword_digest_to_users password_digest:string

but this throws the error: Could not find generator add_passsword_digest_to_users.

i have used the rails generate command before and it worked perfectly. I'm not sure why I am getting this problem now.

version: Rails 3.2.8, ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

Solution

  • Try:

    rails generate migration add_passsword_digest_to_users password_digest:string

    You simply forgot migration which is the generator to use for the other arguments.
