Ruby on rails rails和mongoid形式中未定义的方法路径

我有两门课；一个

日

班和一个

学院班

班。一天由许多大学课程组成，一天是在大学课程之前创建的。我得到的错误

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'

我的大学班级模式

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

在展示页面上创建一个为期一天的大学课程。以下是创建大学班级的表格：

<%= 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 %> 

两种车型的路线：

resources :days do 
  resources :college_class
end

这给了我们这些：

 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

我真诚地感谢在这方面得到的任何帮助。谢谢

尝试将routes.rb更改为此

resources :days do 
  resources :college_classes
end

---

根据您的路线表，我可以看到路径为

day\u college\u class

，因此应该是

day\u college\u class\u path

@ArupRakshit，这不是正确答案。解决方案是修复

资源

，如下所示。资源应该是复数的，而不是单数的。@meagar Humm。。“我看得见，”有人回答。我怎么猜，OP想要什么名字。这两方面都是事实。如果OP写的路径正确，那么可能是他输入的路径有误，，，或者是你说的。@ArupRakshit这是一个输入错误。我已经看了大约一个小时了，出于某种原因，我完全忘记了多元化的大学课程路线。“即使一个人的日子是多元化的，他一直盯着我看。”阿鲁普拉克希特说，是因为铁路吗？熟悉Rails。这个问题有一个客观正确的答案，而不是你建议的答案。他甚至没有选择使用你建议的

day\u college\u class\u path

。Rails正在根据他的模型名生成该名称。就在那里完成了。不得不等10分钟。再次感谢。
