ruby-on-rails - 事件模型在机架测试期间发送验证错误两次。

Question

我有一个简单的 restful rails api 设置来提供 json 响应，我有一个模型 line.rb，我在其中进行了以下验证。

validates :title, :presence => true, :length => {:minimum => 3, :maximum => 40},
:appropriate_title => {:message => "cannot have . and /"}
validates :department, :presence => true
validates :owner, :presence => true
validates :account, :presence => true
validate  :unique_inputs
validates :title, :uniqueness => { 
  :scope => :account, 
  :message => 'is already taken for this account', 
  :case_sensitive => false }

在我的规范中，我有以下套件

 it "with invalid attributes" do
 post"#{url}/#{account.name}.json", :api_key => application.key, :line => {:department => "Survey"}
 --some assertions --
 body = JSON.parse(last_response.body)
 body.should eql({"error"=>{"message"=>"[\"Title can't be blank\", \"Title is too short (minimum is 3 characters)\",]"}})
 end

如您所见，因为我没有提供行的标题，所以它应该触发验证错误并满足我的断言，但是我两次遇到相同的验证错误。

  {"error"=>{
    "message"=>"[\"Title can't be blank\", \"Title is too short (minimum is 3 characters)\", \"Title can't be blank\", \"Title is too short (minimum is 3 characters)\"]"
    }}

这真的很奇怪，因为在开发模式下我没有两次收到此验证错误。如果您怀疑我在我的 Controller 中做错了什么，以下是我在我的 Controller 中的内容

@line = @current_user.lines.new(params[:line])
if @line.save
  respond_with(@line)
else
  render :json => {:error => {:message => @line.errors.full_messages}}
end

我不知道这是机架测试的错误还是我做错了什么。

你试过吗:

validates :department, :presence => true
validates :owner, :presence => true
validates :account, :presence => true
validate  :unique_inputs
validates :title, :presence => true, 
                  :length => {:minimum => 3, :maximum => 40},
                  :appropriate_title => {:message => "cannot have . and /"},
                  :uniqueness => { 
                    :scope => :account, 
                    :message => 'is already taken for this account', 
                    :case_sensitive => false }
