Question

I have a problem where Rails is searching an additional subdirectory based on the controller path. Is there a way to get rails to stop searching one extra subdirectory? I kind of like the directory structure that I have now. Here’s the details:

Rails will return this error message. As you can see, it’s going for v1 twice:

Template is missing
Missing template api/v1/v1/print

I have a controller in app/controllers/api/v1/v1_controller.rb and a view in app/views/api/v1/print.html.erb

The specific route in config/routes.rb is (semi-truncated):

namespace :api do
    scope module: :v1 do
        match "v1/print",
            :to => "v1#print"
    end
end

Based on the routes, it looks OK. Rake routes show this:

api_v1_print GET|POST /api/v1/print(.:format)  api/v1/v1#print {:format=>"html"}

Why is it going one directory too deep?

Answer 1

The problem is that Rails assumes there’s a subdirectory per each controller. The duplication is formed since you have v1 in the module and in the controller name. I wouldn’t go against Rails’ conventions. Instead I would change the name of the controller to API controller (or something similar) and put the templates under the directory called API.

In case you still want to do this, simply use render within your print action and specify the exact file you’d like to use (see here)
