RoR嵌套表单验证

Question

我的org_person.rb模型中有以下内容

   class OrgPerson < ActiveRecord::Base
        has_and_belongs_to_many :TypRole
        has_and_belongs_to_many :OrgContact
        has_one :OrgCredential, dependent: :destroy
        belongs_to :OrgCompany, foreign_key:"org_company_id"
        belongs_to :TypPosition, foreign_key:"typ_position_id"
        validates :first_name, presence: true
        validates :last_name, presence: true
        accepts_nested_attributes_for :OrgCredential
    end

    class OrgCredential < ActiveRecord::Base
        belongs_to :OrgPerson, foreign_key:"org_person_id"
        validates :user_name, presence: true
        validates :password, length: { minimum: 6 }
        before_create :create_remember_token
        has_secure_password
    end

并在我的 org_person_controller.rb

中

    def new
        @person = OrgPerson.new
    end

并在我的 new.html.erb

中

   <%= form_for(@person) do |f| %>
        <%= render 'shared/error_messages' %>
        <div class="col-md-12 ">
          <%= f.text_field :first_name, placeholder: "First Name", :class => "form-control" %>
          <%= f.text_field :last_name, placeholder: "Last Name", :class => "form-control" %>
          <%= f.fields_for :org_credentials do |oc|%>
                <%= oc.password_field :password, placeholder: "Password", :class => "form-control" %>
                <%= oc.password_field :password_confirmation, placeholder: "Password Confirmation", :class => "form-control" %>
          <% end %>
        <%= f.submit "Create my account", class: "btn btn-large btn-primary" %>
        </div>
   <% end %>

在 shared / error_messages

中

     <% if @person.errors.any? %>
         <div id="error_explanation" class="col-md-12">
           <div class="alert alert-danger" role="alert">
             The form contains <%= pluralize(@person.errors.count, "error") %>.
           </div>
           <ul>
           <% @person.errors.full_messages.each do |msg| %>
             <li>* <%= msg %></li>
           <% end %>
           </ul>
         </div>
     <% end %>

问题是必须填写所有字段才能通过。但是，当我提交一个空表单时，我只会收到错误“名字不能为空”和“姓氏不能为空”。密码验证未显示。如果有人有任何见解，请发表评论。这让我疯了。

Models中的许多错误都可能导致您遇到的问题。

您的Models设置应如下所示

class OrgPerson < ActiveRecord::Base
  has_and_belongs_to_many :typ_roles
  has_and_belongs_to_many :org_contacts
  has_one :org_credential, dependent: :destroy
  belongs_to :org_company, foreign_key:"org_company_id"
  belongs_to :typ_position, foreign_key:"typ_position_id"
  validates :first_name, presence: true
  validates :last_name, presence: true
  accepts_nested_attributes_for: org_credential #this is much important
end

class OrgCredential < ActiveRecord::Base
  belongs_to :org_person, foreign_key:"org_person_id"
  validates :user_name, presence: true
  validates :password, length: { minimum: 6 }
  before_create :create_remember_token
  has_secure_password
end

与has_one org_credential有org_person关系，因此new.html.erb

中的这一行

<%= f.fields_for :org_credentials do |oc|%>

应该是

<%= f.fields_for :org_credential do |oc|%>

您应该查看这些 Guides ，以便正确设置model associations。
