As far as I know, models aren't associated with a controller. So you could just 'rails generate model ModelName field:type' three times for the Post, Catalog, and Tag models. Then in some controller, you can write:

class PostsController < ApplicationController   def new     @title = "Some page"     @val = 10

    @post = Post.new     @post.email = "xxx@yahoo.com"

    @catalog = Catalog.new     @catalog.name = "Pottery Barn"

    @tag = Tag.new     @tag.name = "dishes"   end

end

And then in new.html.erb, you can write:

<h1>Posts#new</h1>

<div>Post model: <%= @post.email %></div> <div>Catalog model: <%= @catalog.name %></div> <div>Tag model: <%= @tag.name %></div> <div>Val: <%= @val %></div>
