link_to custom action/route...

[Mark Locklear]

So, I have a somewhat complicated route that looks like this...

http://localhost:3000/rubrics/55/results/by_cred

In my config/routes I have:   match 'rubrics/:id/results/by_cred' => 'results#by_cred'

...and the action itself is pretty basic:

  def by_cred
    @rubric = Rubric.find_by_id(params[:id])
    @results = Result.find_all_by_rubric_id(params[:id])
  end

However, when I run 'rake routes' I don't get anything in the path column...

<no handy link_to helper here>        /rubrics/:id/results/by_cred(.:format)         results#by_cred

The route/action works great if I manually type it in the browser, however I want to add a link to this route in the view. How can I do that?

Try changing `match` to `get`?

No change. Route still works in the browser, but no change in 'rake routes'.

match 'rubrics/:id/results/by_cred' => 'results#by_cred', :as => route_name

will give you route_name_path and route_name_url helpers.

Is Rubric a resource? What version of Rails? It looks like results is a nested resource under rubrics. 

Rails 3 

resources :rubric do 

  resources :results do 

    member { :get => :by_cred}

  end

end

If not, I believe Tony's approach is the next best practice but to get a named route you need to supply :as => 'by_cred' to the get method.

Here is config/routes, and 'rake routes'...

You need to add on an "as" to the end.

:as => "results_by_cred"

Should do the trick. You will end up with a results_by_cred_path helpers this that you pass a result id to.

The other option is to nest the results resource inside of the rubric resource and add a "collection" resource to it. The rails guides on routing should point you in the right direction for that. I'd type out the code but I'm on my iPhone.

Mark, my code above should work with your nested routes setup without the extra get statement if you replace member with collection as Levi has mentioned. Member would require a Results id. 

[Mark Locklear]

Boom! That worked Levi. Thanx!
