Question

As I have written in the title I get the following error when I try to click on my games page.

This is what I have in my games_controller:

   def email

    respond_to do |format|
       user = @game.user
       email = user.email
       g = GameTrade.game_interest(user)
       g.deliver
       format.html { redirect_to root_url }
       format.json { render json: @game }
    end
   end

and this is what I have in the show.html.erb

 <%= button_to "Send Email", :action => 'email'%>

in my routes page I do have the line resources :games

Answer 1

“email” is not a standard route for a resource, so you’ll need to add a route for it. Ideally this would be a POST request, since following that link (button) causes changes to occur. Finally, you should really stick to using the url helpers rather than specifying actions as they make your code a little brittle.

Try something like this in your routes.rb:

resources :games do
  post 'email', :on => :member
end

Then in your view, generate your button like so:

<%= button_to "Send Email", email_game_path(@game) %>

You’ll then need to find the game in your email action in the usual way before you can do anything with it:

@game = Game.find(params[:id])
