ruby-on-rails - Rails 表单错误 : syntax error, 意外的 keywords_ensure，期望输入结束

Question

我不知道问题出在哪里。当我转到带有表单的页面时，出现错误:

syntax error, unexpected keyword_ensure, expecting end-of-input

这是我的表单代码:

<%= form_tag ({controller: :skills, action: :update}, :method => :put, 
    :class => "skill-form", :remote => true) do  %>

    <%= select_tag :label,
       options_for_select( @crafts.collect {|craft| [craft.label, craft.label]}),
       include_blank: true,  :id => 'selectme', 
       :class => 'field field288 chosen-select' %>

    <%= submit_tag "ADD +", :id => "clickme", :class => 'button' %>

<% end %>

Answer 1

从 form_tag 中删除空格:

<%= form_tag({controller: :skills, action: :update}, :method => :put, 
    :class => "skill-form", :remote => true) do  %>
