Question

All of the tutorials I’ve seen so far for RoR have shown me generating models like:

rails generate User name:string placeofbirth:string

This generates a class for the model, and only actually references an attribute if I apply a validation of some kind.

So my question is, how do I use a ‘code’ first approach when creating my models. Or is it the rails way to just right down on paper the attributes you want, run the generate command with each attribute you want and it’s type, then run the rake db:migrate command?

I’d love some more proven patterns on this subject because so far the way I’ve seen seems too empty.

Answer 1

Yes, this is the rails way- migration comes first and generates the code and the database- and the model class inspects the database to see what fields are there and make accessible via methods.

You can do gem install annotate_models if you want to get some comments in your model class with the attribute names and types.
