没有传递给新行动的参数(Params not being passed to new action)

 我在视图中有一个表单： 
 
<%= form_tag(new_admin_course_path(chichi: @provider.id), {method: :get}) do %>
    <%= submit_tag I18n.t('views.courses.index.add_new') %>
<% end %>
 
 @provider.id等于1（与Pry检查）。 
 
 new_admin_course_path落在courses_controller#new 。 从动作本身（使用binding.pry帮助）我得到了params的内容，这是我发现的： 
 
pry(#<Admin::CoursesController>)> params
=> {"utf8"=>"✓", "commit"=>"Add course", "controller"=>"admin/courses", "action"=>"new"}
 
 我不是新的Rails，但我不知道为什么会发生这种情况，而且我没有得到我通过辅助方法传递的信息。 
 
 任何想法为什么发生这种情况？ 

I have a form in the view:
 
<%= form_tag(new_admin_course_path(chichi: @provider.id), {method: :get}) do %>
    <%= submit_tag I18n.t('views.courses.index.add_new') %>
<% end %>
 
@provider.id is equal to 1 (checked with Pry).
 
new_admin_course_path lands in courses_controller#new. From the action itself (with binding.pry help) I got the content of params and this is what I found:
 
pry(#<Admin::CoursesController>)> params
=> {"utf8"=>"✓", "commit"=>"Add course", "controller"=>"admin/courses", "action"=>"new"}
 
I'm not new in Rails, but I have no idea why this is happening and I'm not getting what I pass through the helper method. 
 
Any idea why this is happening?
