Question

I have a partial in my rails app that loads the vote form (It’s just a select with numbers ranging from 1-5). I’m now making another partial that loads up if the user has already voted it’s suppose to be an EDIt partial where you get selected the value that you voted and if you wanted to you could change it. But for some reason is not working, here’s the code for it.

#Finds the vote by passing the user and the article  
<%= @vote = Vote.find_vote_by(current_user,@article) %>

#Renders the partial with the vote variable loaded up with the vote that was found
<%= render :partial => "votes/edit_vote", :locals => {:vote => @vote} %>

And this is the partial

<% form_for(vote, :url => {:controller => 'votes', :action => 'edit'}) do |f| %>

<%= error_messages_for :vote %>

<p><%= f.hidden_field :article_id %></p>
<p>
  <%= f.label :value, "Value for the vote: "%>
  <%= f.select :value, {"1" => "1","2" => "2","3" => "3","4" => "4", "5" => "5"}, :selected => vote.value %>
</p>
<p>
   <%= f.submit "Cloud-it!" %>
</p>

<% end %>

But for some reason the vote variable is not containing anything not the article_id, nor the value method, any ideas?

EDIT1: Per request here’s what’s debug @vote is outputting (It it indeed a sane value)

attributes: 
created_at: 2010-09-02 14:39:04
updated_at: 2010-09-02 14:39:04
id: 1
value: 4
article_id: 1
user_id: 1
attributes_cache: {}

EDIT2

I tried clearing the partial code, in order to output this:

<%= debug @vote%>
<%= @vote.value %>

If i debug @vote it comes out perfect, will all the attributes and such. But whenever i add the second line it, It’s not working it tells me that there’s no .value, i tried .id, .article and nothing is as if it didn’t exist. Any ideas?

EDIT3

Here’s the vote by

 named_scope :find_vote_by, lambda {|user,article| {:conditions => {:user_id => user, :article_id => article}}}

Answer 1

The reason behind it, it’s that named scopes actually return named scopes, and you can’t access the attributes just like it were a Vote class. I fixed this by changing the way to retrieve the vote and just forgetting about using that named scope. I accomplished it by using:

 <% @vote = current_user.votes.find_by_article_id(@article)%>

which is a Rails method and actually returns a vote class. Then i just passed it to the partial and the magic worked!

Thank you so much to thenduks, without his help i couldn’t had done it.
