    <p>So I have a polymorphic favorite model that allows users to favorite all kinds of different things (and currently works ok methinks). I'm now trying to destroy their favorites but having difficulties selecting the favorite to destroy, I don't know how to start the form_for. </p> <p>My create looks like this:</p> <p>units_controller.rb - here I create the @favorite for the form_for</p> <pre><code> @favorite = Favorite.new @favorable = @unit </code></pre> <p>_favorite.html.erb</p> <pre><code>&lt;%= form_for([@user, @favorable, @favorite]) do |f| %&gt; &lt;div&gt;&lt;%= f.hidden_field :favorer %&gt;&lt;/div&gt; &lt;%= f.submit "Favorite", class: "btn btn-large btn-primary" %&gt; &lt;% end %&gt; </code></pre> <p>favorites_controller.rb</p> <pre><code> def create @user = User.find(params[:user_id]) @favorite = @favorable.favorites.new(params[:favorite]) @favorite.favorer = current_user @favorite.save # Favorite id: 1, favorer: 2, favorable_id: 1, favorable_type: "Unit" respond_to do |format| format.html { redirect_to :back } format.js end end </code></pre> <p>Here's what I've got so far on delete but I'm unsure how to call the form_for:</p> <p>_unfavorite.html.erb</p> <pre><code>&lt;%= form_for([@user, @favorable, @favorite], # problems here as @favorite is Favorite.new html: { method: :delete }, remote: true) do |f| %&gt; &lt;%= f.submit "Unfavorite", class: "btn btn-large" %&gt; &lt;% end %&gt; </code></pre> <p>favorites_controller.rb</p> <pre><code>def destroy @favorite = Favorite.find(params[:id]) @favorite.destroy respond_to do |format| format.html { redirect_to @user } format.js end end </code></pre> <p>My follow model uses this, but I'm not sure how to nest it under /users/1/units/1/favorites</p> <pre><code>current_user.relationships.find_by_followed_id(@user) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
