Rails - 显示用户在上个月开始关注的用户(Rails - Show the users that a user started following in the last month)

 对这个问题道歉，我还在学习铁轨。 我试图在我的HTML中显示 - 用户在上个月内开始关注的所有用户（即您已关注的最近用户）。 我尝试了两种方法 - 都不成功。 我的第一次尝试是在我的控制器中，但我得到的最接近的是显示用户我已经开始关注上个月创建的用户。 我的第二次尝试是在我的用户模型中 - 但我得到未定义的方法`call'for＃你的意思是？ 呼叫者

<div class="tab-content">        
<div id="fire" class="tab-pane fade">
        <% @followingurecent.each do |recentfollowing| %>
            <div class="box">
                <center>
                <%= image_tag recentfollowing.avatar, width: 85 %>
                </center>
            </div>
        <% end %>
</div>
</div>
 
 Users_controller.rb 
 
def following
    @user = User.find(params[:id])
    now = Time.now
    @followingurecent = @user.following.where(created_at: (now - 1.month)..Time.now)
end
 
 User.rb 
 
has_many :active_relationships, class_name: "Relationship", foreign_key: "follower_id", dependent: :destroy
has_many :passive_relationships, class_name: "Relationship", foreign_key: "followed_id", dependent: :destroy
has_many :following, through: :active_relationships, source: :followed
has_many :followers, through: :passive_relationships, source: :follower

def follow(other)
    active_relationships.create(followed_id: other.id)
    Notification.create(recipient: @user, actor: User.current_user, action: "Followed", notifiable: @user)
end
def unfollow(other)
    active_relationships.find_by(followed_id: other.id).destroy
end
def following?(other)
    following.include?(other)
end
def followingrecent
    now = Time.now
    self.following.where(active_relationships.where.(created_at: (now - 1.day)..Time.now))
end

Apologies for the question, I'm still learning rails. I'm trying to show in my html - all the users that a user has started following within the last month (i.e. recent users you've followed). I've tried two approaches-both unsuccessful. My first try was in my controller but the closest I got was showing users I've started following who were created in the last month. My second try was in my user model - but I get undefined method `call' for # Did you mean? caller
