Question

So, I have the following link-to:

 <%= link_to(outing_add_guests_path, :class => 'modal') do %>
 <div id="notImportant"></div>
 <% end %>

When I click on it, Rails tells me that

No route matches {:controller=>"outings", :action=>"add_guests"}

However, here’s my routes file:

resources :outings do
  get "/add_guests" => "outings#add_guests"
  post "/add_guests" => "outings#add_guests"
  delete "/remove_guests" => "outings#remove_guests"
end

and the corresponding action from my Outings Controller:

def add_guests
    @outing_guest = OutingGuest.new(:outing_id => params[:outing_id])
    @outing_guest.user_id = params[:user_id]
    if @outing_guest.save
        flash[:notice] = "Guest added successfully"
        redirect_to({ :action => 'outing', :id => params[:outing_id] })
    else
        flash[:notice] = "Guest could not be added"
        redirect_to({ :action => 'outing', :id => params[:outing_id] })
    end
end

Is there any reason Rails would be unable to detect my controller or its actions?

EDIT: Here’s part of the results from rake routes

            outing_add_guests GET    /outings/:outing_id/add_guests(.:format)                outings#add_guests
                              POST   /outings/:outing_id/add_guests(.:format)                outings#add_guests

Answer 1

I notice your link_to is not consistent with the other routes

outing_add_guests_path
outings_add_guests_path

Did you do rake routes to verify that outing_add_guests_path exists?

EDIT:

Your rake routes shows you need an outing_id so your routes aren’t setup right (at least not for the POST). I’d fix them the way @RyanBigg is suggesting.
