Question

I am trying to use the vote_fu gem and I encounter a problem that other have as well, but I can’t solve this with others’ solutions..

I don’t think the problem is related directly to the gem.. but rather to some wrong route or a missing parameter..

I have a Msg model which I included the act_as_voteable.
For the User Model I added act_as_voter

In the Msg controller I added

def votefor
    @msg= Msg.find(params[:id])
    current_user.vote_for(@msg)
    redirect_to :back
end

In routes:

 resources :msgs do
        member do
            post :votefor
        end
    end

And to the show of Msg I added

<%= link_to "Vote Up", votefor_msg_path(@msg), :method => :post %>

But when I click on the link created I get

Routing Error

No route matches [GET] "/msgs/1/votefor"

Why does it ‘GET’ instead of ‘POST’? What am I missing?

Answer 1

I think its very late to answer this question & I mostly think you must have figured it out… I ran into the same issue & I understood the reason why..

This is a sample comment from routes.rb

  # Sample resource route with options:
  #   resources :products do
  #     member do
  #       get 'short'
  #       post 'toggle'
  #     end

the post 'toggle' here is not the post-controller but :method => 'post'

link_to default uses :method => 'get' but you can override it using :method => 'post'

if u use link_to .. in the example without :method => 'post'

your routing should be

resources :msgs do
   member do
   get :votefor
   end
end

Hope this helps!

Update:

For the doubt you have:

link_to with a :method => :post

use this

<%= link_to "Vote Up", votefor_msg_path(@msg), :method => :post %>

and in the routes it should be

resources :msgs do
       member do
       post :votefor
       end
end

the post :votefor .. is :method => :post not the posts controller.
