ruby-on-rails - 简单形式未定义方法路径

Question

我是使用简单形式的新手。一开始我想制作一个简单的表格。

#country_controller
def edit
  @country = Country.find(params[:id])  
end

#edit.html.erb
<%= simple_form_for @country do |f| %>
  <%= f.input :username %>
  <%= f.input :password %>
  <%= f.button :submit %>
<% end %>

但我收到此错误

undefined method `country_path' for #<#<Class:0x007fdb21098e00>:0x007fdb2108cad8>

我的路线

 management GET    /management(.:format)                              management/home#index
             management_settings GET    /management/settings(.:format)                     management/settings#list
        management_country_index GET    /management/country(.:format)                      management/country#index
         edit_management_country GET    /management/country/:id/edit(.:format)             management/country#edit
              management_country PATCH  /management/country/:id(.:format)                  management/country#update
                                 PUT    /management/country/:id(.:format)                  management/country#update
                                 DELETE /management/country/:id(.:format)                  management/country#destroy

因为您的路由稍微不标准，您需要将 url 显式传递给 simple_form_for

<%= simple_form_for @country, url: management_country_path(@country) do |f| %>
