rails和mongoid形式的未定义方法路径

我有两个类;一个Day类和一个CollegeClass类。这一天是由许多大学课程组成的，而这一天是在大学课堂之前创建的。错误即时得到rails和mongoid形式的未定义方法路径

ActionView::Template::Error (undefined method `day_college_classes_path' for#<#<Class:0xa0627dc>:0xa06bd3c>): 
26: <% end %> 
27: <% end %> 
28: 
29: <%= form_for [@day, CollegeClass.new] do |f| %> 
30: <%= f.text_field :module, placeholder: "Module" %> 
31: <br> 
32: <%= f.text_field :lecturer, placeholder: "Lecturer" %> 
app/views/days/show.html.erb:29:in `_app_views_days_show_html_erb___616937818__626026478'

这里是我的天模型

class Day 
    include Mongoid::Document 
    field :user, type: String 
    field :date, type: String 

    embeds_many :college_class 
    accepts_nested_attributes_for :college_class 
end

我的大学课堂模式

class CollegeClass 
    include Mongoid::Document 

    field :module,  type: String 
    field :room,  type: String 
    field :lecturer, type: String 
    field :start_time, type: String 
    field :end_time, type: String 

    embedded_in :day 

    embeds_many :notes 
    embeds_many :tasks 

    accepts_nested_attributes_for :notes 
    accepts_nested_attributes_for :tasks 
end

一个大专班是一天的节目页面上创建。下面是创建大学课程的表格：

<%= form_for [@day, CollegeClass.new] do |f| %> 
<%= f.text_field :module, placeholder: "Module" %> 
<br> 
<%= f.text_field :lecturer, placeholder: "Lecturer" %> 
<br> 
<%= f.text_field :room, placeholder: "Room" %> 
<br> 
<%= f.text_field :start_time, placeholder: "Start Time" %> 
<br> 
<%= f.text_field :end_time, placeholder: "End Time" %> 
<br> 
<%= f.submit %> 
<% end %>

当天控制器中没有show方法。这些都为建立一个新的学院控制器动作类

def create 
    @day = Day.find(params[:id]) 
    @class = @day.college_class.create(class_params) 
    redirect_to @day 
    end 

    private 

    def class_params 
     params.require(:college_class).permit(:module, :lecturer, :room, :start_time, :end_time) 
    end

的两个车型路线：这让我们这些

resources :days do 
    resources :college_class 
end

：

day_college_class_index GET /days/:day_id/college_class(.:format)   college_class#index 
         POST /days/:day_id/college_class(.:format)   college_class#create 
    new_day_college_class GET /days/:day_id/college_class/new(.:format)  college_class#new 
    edit_day_college_class GET /days/:day_id/college_class/:id/edit(.:format) college_class#edit 
     day_college_class GET /days/:day_id/college_class/:id(.:format)  college_class#show 
         PATCH /days/:day_id/college_class/:id(.:format)  college_class#update 
         PUT /days/:day_id/college_class/:id(.:format)  college_class#update 
         DELETE /days/:day_id/college_class/:id(.:format)  college_class#destroy 
        days GET /days(.:format)        days#index 
         POST /days(.:format)        days#create 
       new_day GET /days/new(.:format)       days#new 
       edit_day GET /days/:id/edit(.:format)      days#edit 
        day GET /days/:id(.:format)       days#show 
         PATCH /days/:id(.:format)       days#update 
         PUT /days/:id(.:format)       days#update 
         DELETE /days/:id(.:format)       days#destroy

我真诚地感激任何&所有帮助我得到这一点。谢谢。

按你的*路线*表，我可以看到的路径'day_college_class'，因此它应该是'day_college_class_path'。 –

@ArupRakshit这不是正确的答案。解决方案是修复'资源'，如下所示。资源应始终是复数，而不是单数。 – meagar

@meagar Humm ..我可以看到，有人回答。我如何猜测，OP想要什么实际名称。这两种方式都是如此。如果OP正确地写*路由*，那么他可能会将路径输入为打字错误,,,或者你说的。 –

试着改变你的routes.rb这个

resources :days do 
    resources :college_classes 
end
