copied!<pre><code>scope ":username" do resources :feedbacks end </code></pre> <p>From the <a href="http://guides.rubyonrails.org/routing.html#prefixing-the-named-route-helpers" rel="nofollow noreferrer">docs</a>:</p> <blockquote> <p>This will provide you with URLs such as /bob/posts/1 and will allow you to reference the username part of the path as params[:username] in controllers, helpers and views.</p> </blockquote> <hr> <p>UPDATE:</p> <p>I have tested and confirmed the accuracy of paozac's <a href="https://stackoverflow.com/questions/7297231/how-do-i-get-the-format-of-my-urls-to-be-username-controller-id-in-rails-3-1/7350998#7350998">answer</a>. I'll clarify it a bit.</p> <p>Suppose you had a <code>@feedback</code> object with an <code>id</code> of <code>12</code>, and the associated user had a <code>username</code> of <code>foouser</code>. If you wanted to generate a URL to the edit page for that <code>@feedback</code> object, you could do the following:</p> <pre><code>edit_feedback_url(:username => @feedback.user.username, :id => @feedback) </code></pre> <p>The output would be <code>"/foouser/feedbacks/12/edit"</code>.</p> <pre><code># A URL to the show action could be generated like so: feedback_url(:username => feedback.user.username, :id => feedback) #=> "/foouser/feedbacks/12" # New new_feedback_url(:username => current_user.username) #=> "/foouser/feedbacks/new" </code></pre> <p>Additionally, as noted by nathanvda in the comments, you can <a href="https://github.com/rails/rails/blob/master/actionpack/lib/action_dispatch/routing/route_set.rb#L181" rel="nofollow noreferrer">pass ordered arguments</a> which will be matched with the corresponding dynamic segment. In this case, the username must be passed first, and the feedback id should be passed second, i.e.:</p> <pre><code>edit_feedback_url(@feedback.user.username, @feedback) </code></pre> <p>Also, if you need help handling the params from the controller, I suggest creating a new question specific to that.</p>
