找不到源关联：在模型关系中跟随。

Question

我正在关注Michael Hartl的rails book并收到以下错误消息：

python -m SimpleHTTPServer

调用ActiveRecord::HasManyThroughSourceAssociationNotFoundError: Could not find the source association(s) :follower in model Relationship. Try 'has_many :following, :through => :active_relationships, :source => <name>'. Is it one of ? 时（其中michael.follower是用户对象）。

以下是关联：

michael

如果我理解正确，你会通过关系模型在用户和关系模型之间建立多对多的关系（我很抱歉同义词）。

我建议改变

has_many :following, :through => :active_relationships, source: :follower
has_many :followers, :through => :passive_relationships, source: :followed

到

has_many :following, :through => :active_relationships, class_name: "User"
has_many :followers, :through => :passive_relationships, class_name: "User"
