验证始终在所有字段上都失败

Question

我在Rails 3.我有一个名为Client的模型，它有name，phone和email。我的模型文件看起来像这样：

class Client < ActiveRecord::Base 
    belongs_to :salon 
    belongs_to :address 
    validates_presence_of :name 
    validates_presence_of :phone 
    validates_presence_of :email 
    accepts_nested_attributes_for :address 
    attr_accessible :address_attributes 
end 

正如你所看到的，都需要name，phone和email。当我转到可以创建新的Client的表单并提交时，无论我在这些字段中输入了什么，所有三个验证都会失败。这里是我的表单文件：

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

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

    <%= f.hidden_field :salon_id, :value => Salon.logged_in_salon.id %> 
    <div class="field"> 
    <%= f.label :name %><br /> 
    <%= f.text_field :name %> 
    </div> 
    <div class="field"> 
    <%= f.label :phone %><br /> 
    <%= f.text_field :phone %> 
    </div> 
    <div class="field"> 
    <%= f.label :email %><br /> 
    <%= f.text_field :email %> 
    </div> 

    <%= f.fields_for :address do |address_form| %> 
    <div class="field"> 
     <%= address_form.label :line1 %><br /> 
     <%= address_form.text_field :line1 %> 
    </div> 
    <div class="field"> 
     <%= address_form.label :line2 %><br /> 
     <%= address_form.text_field :line2 %> 
    </div> 
    <div class="field"> 
     <%= address_form.label :city %><br /> 
     <%= address_form.text_field :city %> 
    </div> 
    <div class="field"> 
     <%= address_form.label :state_id %><br /> 
     <%= select("client[address]", "state_id", State.all.collect {|s| [ s.name, s.id ] }) %> 
    </div> 
    <div class="field"> 
     <%= address_form.label :zip %><br /> 
     <%= address_form.text_field :zip %> 
    </div> 
    <% end %> 

    <div class="actions"> 
    <%= f.submit %> 
    </div> 
<% end %> 

这里是我的create行动：

def create 
    @client = Client.new(params[:client]) 

    respond_to do |format| 
     if @client.save 
     format.html { redirect_to(@client, :notice => 'Client was successfully created.') } 
     format.xml { render :xml => @client, :status => :created, :location => @client } 
     else 
     format.html { render :action => "new" } 
     format.xml { render :xml => @client.errors, :status => :unprocessable_entity } 
     end 
    end 
    end 

任何想法，为什么发生这种情况？

Answer 1

这是因为您将:address_attributes设置为唯一可访问的属性。更改

attr_accessible :address_attributes 

到

attr_accessible :address_attributes, :name, :phone, :email 

或不使用质量分配。
