ruby-on-rails - Rails SelectTag include_blank 不工作

Question

我正在使用 select_tag 并使用它从数据库中填充它。

<%= select_tag 'project', options_from_collection_for_select(@issue_statuses,"id", "name"), :include_blank  => 'Select' , html_options = { :onblur => "myblur(this);", :onChange=> "submit_selected(this);", :style=> "visibility:visible;" } %>

但是在包含“:include_blank”时出现以下错误:

compile error
/home/hitesh/redmine-1.3.0-1/apps/redmine/vendor/plugins/redmine_polls/app/views/questions/index.html.erb:42: syntax error, unexpected ')', expecting tASSOC
...le=> "visibility:visible;" } ).to_s); @output_buffer.concat ...
                          ^

如何在上面的代码中包含空白或提示值。

谢谢。

在其中包含 :include_blank 调用:{}

<%= select_tag 'project', options_from_collection_for_select([],"id", "name"), {:include_blank  => 'Select', :onblur => "myblur(this);", :onChange=> "submit_selected(this);", :style=> "visibility:visible;" } %>
