I have a has_and_belongs_to_many relationship between client "projects" and "features" that they selected through a collection_checkbox administered through a join table called projects_features.

So: each user is able to create projects, and these projects have features that they select and save using a checkbox list - awesome.

I am now trying to edit the show view when the customer wants to take a look at his project, and want to display a list of features his particular project has. How would you do this? Could I do it through a loop displaying from the table or would I need to store the matching features into an array and then display them?

The features are already an attribute of the project, so you can do in the view something like the following... 

<h4>Features</h4>

<% @project.features.each do |feature| %>
  <%= feature.name %><br>
<% end %>

This is very simple but you can enhance by using a HTML table or other presentation style.
