Question

I already had an issue with devise that i posted here : Weird route malfunction, mix between devise and own controller
I was hoping it was just a one time issue but devise is driving me crazy !

If I do this everything is ok

<% if user_signed_in? %>
  <% if current_user.ideas.include?(@idea) %>
    <%= button_to 'Remove from Favorites', user_idea_subscription(@idea.id), method:    :delete%>
  <% else %>
    <%= button_to 'Add to Favorites', user_idea_subscriptions_path(current_user, :idea_id => @idea) %>
  <% end %>
<% end %>

But if I do this :

<% if user_signed_in? and current_user.ideas.include?(@idea) %>
  <%= button_to 'Remove from Favorites', user_idea_subscription(@idea.id), method:    :delete%>
<% else %>
  <%= button_to 'Add to Favorites', user_idea_subscriptions_path(current_user, :idea_id => @idea) %>
<% end %>

Then I’ve got this error :

No route matches {:controller=>"idea_subscriptions", :idea_id=>#<Idea id: 12, name: "Chute libre", description: "50sec a 50m/s", created_at: "2012-07-12 10:02:30", updated_at: "2012-07-12 10:02:30">}

Everything should be ok but why I’m getting that error ? (beside there is no other information on the error)
Thanks for your help and my sanity !

Answer 1

I think it is normal behaviour because in second case you are trying to call

user_idea_subscriptions_path(current_user, :idea_id => @idea)

then user is not signed in, so current_user is nil
