Colllection_check_boxes構文エラー、予期しない ''、期待 '）'

Question

私が使用していヘルパーcollection_check_boxes：

<li class="form-fields__group"> 

    <label>Ownership type</label> 
     <div class="field"> 
     <%= collection_check_boxes (:freelancer, :ownership_type_ids, OwnershipType.all, :id, :title) %> 


     </div> 
    </li> 

コンソールのエラーで：

SyntaxError (/home/ubuntu/workspace/app/views/freelancers/edit.html.erb:192: syntax error, unexpected ',', expecting ')' 
...ction_check_boxes (:freelancer, :ownership_type_ids, Ownersh...

...nershipType.all, :id, :title));@output_buffer.safe_append=' 
...        ^): 

なぜこのエラー？ collection_check_boxesの何が間違っていますか？

<%= collection_check_boxes (:freelancer, :ownership_type_ids, OwnershipType.all, :id, :title) %>
