为什么RSpec在验证失败？

Question

我有这些验证：

it "should have 100 adventure points" do 
    user = User.new 
    user.adventure_points.should == 100 
end 

it "should be level 1" do 
    user = User.new 
    user.level.should == 1 
end 

it "should have 10 sapphires" do 
    user = User.new 
    user.sapphires.should == 10 
end 

然后，我也有我的移民：

t.string :name,       :limit => 20 
    t.integer :strength_points,    :default => 0 
    t.integer :dexterity_points,    :default => 0 
    t.integer :magic_points,     :default => 0 
    t.integer :accuracy_points,    :default => 0 
    t.integer :health_points,    :default => 0 
    t.integer :level,      :default => 1 
    t.integer :adventure_points,    :default => 100 
    t.integer :sapphires,     :default => 10 
    t.integer :duel_wins,     :default => 0 
    t.integer :duel_losses,     :default => 0  
    t.string :image_url  
    t.integer :strength 

当我运行RSpec的我得到：

A new User 
    is not valid without a name 
    is not valid without a first class 
    is not valid without a password 
    should have 100 adventure points 
    should be level 1 (FAILED - 1) 
    should have 10 sapphires (FAILED - 2) 

Failures: 

    1) A new User should be level 1 
    Failure/Error: user.level.should == 1 
     expected: 1 
      got: nil (using ==) 
    # ./spec/models/user_spec.rb:28 

    2) A new User should have 10 sapphires 
    Failure/Error: user.sapphires.should == 10 
     expected: 10 
      got: nil (using ==) 
    # ./spec/models/user_spec.rb:33 

为什么会出现这些错误在水平上，蓝宝石，但它适合adventure_points？此外，如果我打开一个控制台并执行User.new，我会得到预期的默认值。这里开什么东西？

Answer 1

自己找到了解决方案，很狡猾的一个。我不得不跑耙：测试：准备，因为测试数据库没有灯具数据，并没有准备：P

Answer 2

数据库默认值在保存模型之前未设置。试试：

 
it "should have 100 adventure points" do 
    user = User.create 
    user.adventure_points.should == 100 
end
