触发错误的
我正在做Michael Hartl的Rails教程，我在第14章
基本上，我正在构建一个Twitter克隆，以学习Rails。
在本章中，用户可以相互关注。
在编写第一个测试以检查这些关系后：
user_test.rb
test "should follow and unfollow a user" do
michael = users(:michael)
archer = users(:archer)
assert_not michael.following?(archer)
michael.follow(archer) # LINE OF THE ERROR (rb:100)
assert michael.following?(archer)
michael.unfollow(archer)
assert_not michael.following?(archer)
end
弹出此错误：
错误
ERROR["test_should_follow_and_unfollow_a_user", UserTest, .192215816000044]
test_should_follow_and_unfollow_a_user#UserTest (6.19s)
ActiveRecord::RecordInvalid:
ActiveRecord::RecordInvalid: Validation failed:
Password can't be blank,
Password is too short (minimum is 6 characters)
app/models/user.rb:102:in `follow'
test/models/user_test.rb:100:in `block in <class:UserTest>'
这很奇怪，因为到目前为止验证工作正常，甚至有一些测试来检查它们的正确行为(如果我删除User模型上的validation，这些测试会正确触发，但test/models/user_test.rb中的错误消失了(
models/user.rb主管

触发错误的model/user.rb方法的方法
# follows a user
def follow(other_user)
following << other_user # LINE OF THE ERROR (rb:102)

我完成了相同的教程，在我的用户模型中，我验证了密码如下：
validates :password, presence: true, length: { minimum: 6 }, allow_nil: true
也许补充allow_nil：真的。
