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 = "[email protected]"

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

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

end

end

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

Posts#new

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

which is inserted in the layout: application.html.erb,

<%= @title %> <%= csrf_meta_tag %>

<%= yield %>
