Colllection_check_boxes語法錯誤，意外 ''，預計 '）'

Question

我使用的輔助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> 

在控制檯錯誤：

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

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

爲什麼這個錯誤？ collection_check_boxes有什麼問題？

Answer 1

相反的：

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

刪除空間：

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