Hi, I have a basic Rails question:
I''m creating a little widget that allows people to call recipes
"favorites". But when they add a recipe, I don''t want them
to see the
"Add as a favorite" button, I want them to see a "Remove from
your
favorites" link. I''m not sure what I need to do in the controller
to
make this happen. Here''s what I have right now:
recipes_controller.rb:
def favorite
Recipe.find(params[:id]).favorites.create(params[:favorite])
flash[:notice] = "You have added this recipe to your favorites."
redirect_to :action => "show", :id => params[:id]
end
show.rhtml:
<%= form_tag :controller => "recipes", :action =>
"favorite", :id =>
@recipe %>
<%= hidden_field "favorite", "user_id", :value =>
current_user.id %>
<%= submit_tag "Add as favorite", :class =>
"favorite" %>
</form>
and I want to replace it with:
<%= link_to ''Un-favorite this recipe'', :controller =>
"recipes", :action
=> "unfavorite", :recipe_id => @recipe, :user_id =>
current_user.id %>

Do I have to do anything in the controller at all, or should it work with just the params[:action] expression in the if statement? If it''s supposed to work with no alterations to the controller, I might have mixed something else up... :) -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I''m guessing you''re saving the favorite relationship in the model, so why not check for that? if @user.favorites.include? @recipe --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
