title: Client Side Validations creating "no implicit conversion of Fixnum into String" error
body: <p>I'm getting a "no implicit conversion of Fixnum into String" error with client-side-validations.  Can't find anything on SO regarding this.  Code is as follows: </p>
  
  <p>Form in the view:  </p>
  
  <pre><code>&lt;% @tournament.sub_tournaments.each_with_index do |sub, i| %&gt;
    &lt;%= f.fields_for :sub_tournaments, sub, :validate =&gt; true do |sub_form| %&gt;
      &lt;div class="tab-content match-content hide"&gt;
        &lt;span class="match_fields"&gt;&lt;/span&gt;
        &lt;fieldset class="emty"&gt;     
          &lt;legend&gt;Match&lt;/legend&gt;
          &lt;div class="add-item add_match"&gt;
        &lt;% if i == 1 %&gt;
          &lt;%= link_to_add_matches_fields(sub_form, :player_matches, i) %&gt;
        &lt;% else %&gt;
          &lt;%= link_to_add_matches_fields(sub_form, :team_matches, i) %&gt;
        &lt;% end %&gt;
          &lt;/div&gt;
        &lt;/fieldset&gt;                    
      &lt;/div&gt;  
    &lt;% end %&gt;
  &lt;% end %&gt;  
  </code></pre>
  
  <p>the view references <code>link_to_add_matches_fields</code> which is in <code>application_helper</code></p>
  
  <pre><code>def link_to_add_matches_fields(f, association, index)
    new_object = f.object.send(association).klass.new
    id = new_object.object_id
    game = Game.find(index + 1)
    fields = f.fields_for(association, new_object, child_index: id) do |builder|
      render("tournaments/form_partials/" + association.to_s.singularize + "_fields", f: builder, game: game)
    end
    link_to('#', :class =&gt; "add-matches-button", data: {id: id, fields: fields.gsub("\n", "")}) do
      '&lt;span class="sign pos"&gt;+&lt;/span&gt;&lt;div&gt;ADD Match&lt;/div&gt;'.html_safe
    end
  end  
  </code></pre>
  
  <p>Everything works through here and passes to either <code>_team_matches</code> or <code>_player_matches</code> correctly.  But in <code>_team_matches</code> - </p>
  
  <pre><code>&lt;fieldset&gt;
    &lt;%= f.hidden_field :_destroy %&gt;
    &lt;legend&gt;Match&lt;span class="remove"&gt;Remove&lt;/span&gt;&lt;/legend&gt;
    &lt;table&gt; 
      &lt;tr&gt; 
        &lt;td&gt; HOME TEAM
  ##this line##  &lt;%= f.collection_select(:home_team_id, TeamDivision.where("game_id = ?", game.id), :id, :name, {include_blank: true}) %&gt;
        &lt;/td&gt;
        ...
  </code></pre>
  
  <p>The marked line is throwing the error - If i take out collection_select and put in another variable, or just text, things are rendering fine.  If change the <code>TeamDivision.where</code> part, it throws the same error.  Based on the full trace (below), it has something to do with client-side-validations, but not sure what could be preventing the form from even being shown...? </p>
