Question

我在appointments的{{1}}中有一个嵌套资源profiles。

route.rb

在我的resources :profiles, only: [:show, :update, :edit] do resources :appointments end我写了这样的新方法

AppointmentsController.rb

我在def new @appointment = Appointment.new end

中有此new方法的表单

appointments/new.html.erb

我在<section class="login-page border-top-blue padding-v-10"> <section class="login-details-div bg-light-grey"> <%= form_for(@appointment, :html => { :class => 'form-horizontal login-form-container login-form-div' }) do |f| %> <h1>Create New Appointments</h1> <div class="form-div-send-for-inlinement-icon-with-text-field"> <span class="form-wrapper "> <i class="fa fa-user login-icon-white login-icon-envelop "></i> </span> <div class="label-input-div input-width"> <label for="" class="login-label-div"></label> <div class="form-wrapper"><%= f.text_area :description, class:'login-icon-white', autofocus: true %></div> </div> </div> <div class="form-div-send-for-inlinement-icon-with-text-field"> <span class="form-wrapper "> <i class="fa fa-envelope login-icon-white login-icon-envelop "></i> </span> <div class="label-input-div input-width"> <label for="" class="login-label-div">topic</label> <div class="form-wrapper"><%= f.text_field :topic, class:'login-icon-white' %></div> </div> </div> <div class="form-div-send-for-inlinement-icon-with-text-field"> <span class="form-wrapper "> <i class="fa fa-envelope login-icon-white login-icon-envelop "></i> </span> <div class="label-input-div input-width"> <label for="" class="login-label-div">Appointment Date</label> <div class="form-wrapper"><%= f.date_field :appointment_date, class:'login-icon-white' %></div> </div> </div> <div class="form-div-send-for-inlinement-icon-with-text-field"> <span class="form-wrapper "> <i class="fa fa-envelope login-icon-white login-icon-envelop "></i> </span> <div class="label-input-div input-width"> <label for="" class="login-label-div">class hours</label> <div class="form-wrapper"><%= f.number_field :class_hours, class:'login-icon-white' %></div> </div> </div> <div class="form-group"> <label for="" class="col-sm-offset-2 col-sm-10 col-xs-offset-2 col-xs-10 col-md-offset-1 col-md-11 login-btn-div"> <%= f.submit "submit", :class => "login-btn" %> </label> <label for="" class="col-sm-offset-2 col-sm-10 col-xs-offset-2 col-xs-10 col-md-offset-1 col-md-11 login-btn-div"> <%= link_to "Cancel", root_path(), :class => "login-btn" %> </label> </div> <% end %> </section> </section>中有一个链接标记用于调用profiles/show.html.erb的这种新方法。

AppointmentsController.rb

我不明白为什么每当我点击此链接时，我都会在网址中找到链接

      <%= link_to "book a class", new_profile_appointment_path, class: 'btn-green2' %>

这是我需要的。但是有一个错误 http://localhost:3000/profiles/3/appointments/new

我无法在这里弄清楚我的错。请帮助。

Answer 1

你表单中的网址应该是这样的：

<%= form_for [@profile, @appointment] do |f| %>
  ...
<% end %>

Answer 2

form_for尝试使用现有路径。您没有appointments_path，但确实有profile_appointments_path

要使用该路径，只需将两个对象传递给form_for

即可

<%= form_for([@profile, @appointment], :html => { :class => 'form-horizontal login-form-container login-form-div' }) do |f| %>

但是，这确实意味着您需要在@profile方法中创建实例变量new ...

   def new
     @profile = Profile.find(params[:profile_id])
     @appointment = Appointment.new
   end

Answer 3

当您使用嵌套资源创建每个约会时，您需要一个用于嵌套约会的配置文件。因此，您需要通过profile_id来创建约会，因为您的路径new_profile_appointment_path也在说。

<%= form_for([@profile, @appointment], :html => { :class => 'form-horizontal login-form-container login-form-div' }) do |f| %>

您还需要在方法中定义@profile。

   def new
     @profile = Profile.find(params[:profile_id])
     @appointment = Appointment.new
   end

使用嵌套资源的undefined方法`appointmentments_path'
