Hey guys I''m new here, I hope, theres someone who can help me because I asked this question on a lot of different platforms on the internet and there was noone who could give me a helpful answer. My problem is actually very simple: I know there is the command "rails g model" or rather "rails g migration" for changing or creating tables. But how can I let my controller AUTOMATICALLY create or change tables? Is there a ruby command that can create new tables such as "CREATE TABLE" in SQL? I''m looking for an answer to this question for so long, if there is someone who knows the answer, please write a comment.

Run sql directly from Rails or don''t you know the sql to create a table? Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You can execute SQL statements in a rails application with the command:
ActiveRecord::Base.connection.execute(''your sql'')
