ruby-on-rails - 从激活令牌加载的 Rails 加载不加载

Question

我尝试从激活令牌加载用户以激活他，但不知何故它失败了：

us = User.find(7)
us.activation_token
 => "BqgLeANnMj9jCCsTp2hy" 
@user = User.load_from_activation_token(us.activation_token)
  User Load (0.4ms)  SELECT "users".* FROM "users" WHERE (activation_token = 'BqgLeANnMj9jCCsTp2hy') LIMIT 1
 => nil 

尽管用户存在并且正在打开并且具有激活令牌，但 load_from_activation_token 找不到它。是否还有其他激活用户的可能性？

Answer 1

us = User.find(7)
token = us.activation_token
 => "BqgLeANnMj9jCCsTp2hy" 

    @user = User.find_by_activation_token(token)

    or 

    @user = User.find_by(activation_token: token)

    or

    @user = User.where(activation_token: token).first
