Question

我有一个名为：school的资源，当我调用form_for（@school）时，它会生成表单操作：

/school.1

我对这一切都是新手，所以任何有关它为什么这样做的线索都会非常感激。 arrrggg！睡眠不足，在3个小时内完成了截止日期！

谢谢：）

routes.rb中：

resource:school

school.rb：

<%= form_for(@school, :url => school_path) do |f| %>
  <% if @school.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@school.errors.count, "error") %> prohibited this school from being saved:</h2>

      <ul>
      <% @school.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= f.label :name %><br />
    <%= f.text_field :name %>
  </div>
  <div class="field">
    <%= f.label :address1 %><br />
    <%= f.text_field :address1 %>
  </div>
  <div class="field">
    <%= f.label :address2 %><br />
    <%= f.text_field :address2 %>
  </div>
  <div class="field">
    <%= f.label :address3 %><br />
    <%= f.text_field :address3 %>
  </div>
  <div class="field">
    <%= f.label :town %><br />
    <%= f.text_field :town %>
  </div>
  <div class="field">
    <%= f.label :county %><br />
    <%= f.text_field :county %>
  </div>
  <div class="field">
    <%= f.label :postcode %><br />
    <%= f.text_field :postcode %>
  </div>
  <div class="field">
    <%= f.label :local_authority_id %><br />
    <%= f.collection_select :local_authority_id, LocalAuthority.all, :id, :name %>
  </div>
  <% if current_user.person.primary_user? %>
    <div class="field">
      <%= f.label 'Are you happy for us to send you regular updates about VRH?' %><br />
      <%= f.check_box :allow_contact %>
    </div>
  <% end %>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

通过使用单一资源方法，你告诉rails只存在其中一个对象，在你的路径文件中我认为你需要改变你的资源：school to ...

resources :schools

如果您确实只想要一所学校，那么我认为您需要将url选项添加到form_for ...

<% form_for(@school, :url => school_path) %>

建议的后续问题解决方案......

我认为你需要的东西会是这样......

# routes.rb
resources :users do
  resources :schools
end
resources :schools

# app/controllers/schools_controller.rb
class SchoolsController < ApplicationController
  def new
    @user = User.find(params[:user_id])
    @school = @user.build_school
  end

  def create
    @user = User.find(params[:user_id])
    @school = @user.build_school(params[:school])
    if @school.save
      # success...
    else
      # fail...
    end
  end

  def edit
    @school = School.find(params[:id])
  end

  def update
    @school = School.find(params[:id])
    if @school.update_attributes(params[:school])
      # success
    else
      # fail
    end
  end
end

# app/views/schools/new.html.erb
<%= form_for([@user, @school]) do |f| %>
  <!-- fields go here -->
<% end %>

# app/views/schools/edit.html.erb
<%= form_for([@user, @school]) do |f| %>
  <!-- fields go here -->
<% end %>

我的routes.rb文件中只有一个与奇异配置文件资源类似的问题：

resource :profile

我花了几个小时才找到解决方案，所以我决定分享它以拯救别人的麻烦我必须通过指定特定格式来删除路径的“（：。格式）”部分（在运行“rake routes”时显示）：

constraints :format => "html" do  
  resource :profile  
end

我还必须将：url选项添加到form_for标记：

<% form_for(@profile, :url => profile_path) %>

并且有效。

Form_for生成以“.1”结尾的资源路径
