爲什麼RSpec在驗證失敗？

Question

我有這些驗證：

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 

然後，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 

當我運行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 

爲什麼會出現這些錯誤在水平上，藍寶石，但它適合adventure_points？此外，如果我打開一個控制檯並執行User.new，我會得到預期的默認值。這裏開什麼東西？

Answer 1

自己找到了解決方案，很狡猾的一個。我不得不跑耙：測試：準備，因爲測試數據庫沒有燈具數據，並沒有準備：P

Answer 2

數據庫默認值在保存模型之前未設置。試試：

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