STI, one controller

by

First. Add some new routes:

resources :highlights, :controller => "ads", :type => "Highlight"
resources :bargains, :controller => "ads", :type => "Bargain"

And fix some actions in AdsController. For example:

def new
  @ad = Ad.new()
  @ad.type = params[:type]
end

For best approach for all this controller job look this comment

That’s all. Now you can go to localhost:3000/highlights/new and new Highlight will be initialized.

Index action can look like this:

def index
  @ads = Ad.where(:type => params[:type])
end

Go to localhost:3000/highlights and list of highlights will appear.
Same way for bargains: localhost:3000/bargains

etc

URLS

<%= link_to 'index', :highlights %>
<%= link_to 'new', [:new, :highlight] %>
<%= link_to 'edit', [:edit, @ad] %>
<%= link_to 'destroy', @ad, :method => :delete %>

for being polymorphic 🙂

<%= link_to 'index', @ad.class %>
