如何在Rails 4上生成模型字段？

Question

I have run

rails generate Model Profile name:string

It have worked and generated all the files. When I see the profile.rb file though it only has the class declaration not the fields.

class Profile < ActiveRecord::Base
end

Do I have to add all the fields manually ?

Answer 1

No, you don't to add fields manually. ActiveRecord will discover them at runtime from the table structure. This is part of rails magic :)
