Ruby on rails RubyonRails |一个表单-三个表（不能保存表单内容）

我试图为用户的详细信息编写一个简单的应用程序表单，将数据保存到三个不同的表中（1.用户，2.公司，3.地址）。 我使用“属于”和“有很多”设置了一些关联，还使用嵌套的属性和字段来构建一个表单。但是我不能保存数据。 我是一个新手，所以可能我犯了一些愚蠢的错误，但我真的无法找到他们，因为3天。也尝试在谷歌和这里的论坛帖子中查找，但没有找到一个代码，其中的问题与child类有关。我在用户、公司和地址之间的联系很奇怪。有人能帮我吗

这是我的表格：

<%= simple_form_for @user do |f| %>

    <h5>Personal Details</h5>
      <%= f.input :firstname, label: 'Your First Name:' %>
      <%= f.input :lastname, label: 'Your Last Name:' %>
      <%= f.input :email, label: 'Your Email:' %>
      <%= f.input :dateofbirth, label: 'Your Date of Birth:' %>
      <%= f.input :phonenumber, label: 'Your Phone Number' %>
    <h5>Adress</h5>

      <%= f.fields_for :adresses do |g| %>
          <%= g.input :street, label: 'Street:' %>
          <%= g.input :city, label: 'City:' %>
          <%= g.input :zipcode, label: 'Zip Code:' %>
          <%= g.input :country, label: 'Country:' %>
      <% end %>

     <h5>Company</h5>  
     <%= f.fields_for :companies do |h| %>
          <%= h.input :name, label: 'Name:' %>
     <% end %>      

     <%= f.fields_for :adresses do |i| %>
          <%= i.input :comstreet, label: 'Street:' %>  
          <%= i.input :comcity, label: 'City:' %>  
          <%= i.input :comzipcode, label: 'Zip Code:' %>  
          <%= i.input :comcountry, label: 'Country:' %>  
      <% end %>

      <%= f.button :submit %>
<% end %>

<%= simple_form_for @user do |f| %>

    <h5>Personal Details</h5>
      <%= f.input :firstname, label: 'Your First Name:' %>
      <%= f.input :lastname, label: 'Your Last Name:' %>
      <%= f.input :email, label: 'Your Email:' %>
      <%= f.input :dateofbirth, label: 'Your Date of Birth:' %>
      <%= f.input :phonenumber, label: 'Your Phone Number' %>
    <h5>Adress</h5>

      <%= f.fields_for :adress_attributes do |g| %>
          <%= g.input :street, label: 'Street:' %>
          <%= g.input :city, label: 'City:' %>
          <%= g.input :zipcode, label: 'Zip Code:' %>
          <%= g.input :country, label: 'Country:' %>
      <% end %>

     <h5>Company</h5>  
     <%= f.fields_for :company_attributes do |h| %>
          <%= h.input :name, label: 'Name:' %>
            <%= h.fields_for :adress_attributes do |i| %>
              <%= i.input :street, label: 'Street:' %>  
              <%= i.input :city, label: 'City:' %>  
              <%= i.input :zipcode, label: 'Zip Code:' %>  
              <%= i.input :country, label: 'Country:' %>  
           <% end %>
     <% end %>      



      <%= f.button :submit %>

class UsersController

在您的user.rb文件中：

class User < ApplicationRecord
  belongs_to :company, inverse_of: :users
  belongs_to :adress,  inverse_of: :users

  validates_presence_of :firstname, :lastname, :email
  validates_length_of :firstname, :maximum => 100
  validates_length_of :lastname, :maximum => 100
  # add nested attributes here not in other models
  accepts_nested_attributes_for :companies
  accepts_nested_attributes_for :addresses

end

在视图中，删除address的多个表单元素。您写了两次。

我对代码做了一些更改，并且能够保存表单，请检查

这是我的表格：

<%= simple_form_for @user do |f| %>

    <h5>Personal Details</h5>

          <%= g.input :country, label: 'Country:' %>
      <% end %>

它现在正在工作，能够用公司地址保存用户、地址和公司。

您是否发现任何错误？还要检查用户参数中的拼写…：comcity不正确。我甚至无法保存，因此无法读取错误列表。但这里有一个屏幕，在我点击提交后，我的控制台会发生什么：谢谢你的建议！实际上，我仍然无法保存它：（这是控制台的错误：@鸽子场您缺少公司的地址\属性，请尝试使用保存检查错误！它将引发异常，以便您能够找到确切的错误。您必须在公司\属性部分使用h.adress\属性。
