ruby-on-rails - Ruby on Rails，将 submit_tag 转移到按钮

Question

我有以下结构：

<script type='text/javascript'>
    $('#check_all').on("click", function(){ $('input[type="checkbox"]').click(); });
</script> 
   <%= form_tag what_to_do_files_path, method: :get do %>
   <%= submit_tag "Delete selected", :commit =>"delete" %>
   <%= submit_tag "Pictures/Info/Raw Int", :commit =>"pictures" %>
   <button type="button" id="check_all">Check / Uncheck All </button>

   lalala
   <%end%>

您可能已经注意到“删除”和“图片/..”按钮与“检查/取消..”按钮不同。然后我需要看起来像我尝试使用的“检查/取消检查按钮”

<%= button_tag(type: "submit", class: "btn btn-default", value:"my_button") do %>
    Update list <i class="icon-repeat"></i>
<% end %>

但是 params[:commit] 没有抓住它。
有什么问题，如何将 submit_tag 转移到按钮中？

另请参阅Railscasts Episode 38 Multibutton forms。

尝试这个

# form

<%= form_tag what_to_do_files_path do %>
 ...
 ...
 ...
  <%= button_tag :class => "btn btn-warning", :name => 'delete' do %> Delete selected <% end %>
  <%= button_tag :class => "btn btn-primary", :name => 'pictures' do %> Pictures/Info/Raw Int <% end %>

<% end %>

您的操作将如下所示：

# controller

def what_to_do_files
  if params[:delete]
    # Do stuff for delete
  elsif params[:pictures]
    # Do stuff for pictures
  else
    # other commit
  end
end
