Question

我刚刚在我的模型文件中创建了一个新的rails文件（名为project.rb）我已经进行了以下验证：

class Project < ActiveRecord::Base

  validates :title, presence: true

end

我有三个属性：title，description和due_date。但是，当我跳入我的终端并键入描述和截止日期（并且没有标题）并点击保存时，它可以正常工作！

我不明白为什么。

 > p.description="lksdf"     ( add description )
"lksdf"
 > p.due_date="kldf"          ( add due_date )
"kldf"

 > p.save
   (0.2ms)  BEGIN

   (4.6ms)  COMMIT
true

2.2.0 :077 > Project.all
  Project Load (0.6ms)  SELECT "projects".* FROM "projects"

Answer 1

我能够找出问题所在。

在重新运行我的服务器之前，我没有正确保存文件，问题解决了！

验证：标题，存在：true不起作用
