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

问题描述

对这个问题表示歉意，我还在学习 Rails.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(即您最近关注的用户).我尝试了两种方法——都没有成功.我的第一次尝试是在我的控制器中，但我最接近的是向用户展示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 - 但我得到了未定义的方法 `call' # 你的意思是?来电者

following.html.erb

<div id="fire" class="tab-pane淡入淡出"><% @followingurecent.each 做 |recentfollowing|％＞<div class="box"><中心><%= image_tag 最近关注.avatar，宽度:85%></中心>
<%结束%>

Users_controller.rb

def 以下@user = User.find(params[:id])现在 = 时间.现在@followingurecent = @user.following.where(created_at: (now - 1.month)..Time.now)结尾

User.rb

has_many :active_relationships, class_name: "Relationship", foreign_key: "follower_id", 依赖: :destroyhas_many:passive_relationships，class_name:关系"，foreign_key:followed_id"，依赖::destroyhas_many :following, through: :active_relationships, source: :followedhas_many :followers, 通过::passive_relationships, 来源::follower定义跟随(其他)active_relationships.create(followed_id: other.id)Notification.create(收件人:@user，演员:User.current_user，动作:已关注"，通知:@user)结尾def取消关注(其他)active_relationships.find_by(followed_id: other.id).destroy结尾def跟随?(其他)以下.包括?(其他)结尾def跟随最近现在 = 时间.现在self.following.where(active_relationships.where.(created_at: (now - 1.day)..Time.now))结尾

解决方案

我会选择控制器解决方案.

但问题是我将寻找关系创建时间，而不是用户(它是用户，对，我的意思是 Follower 是用户模型，对吗?).

所以:

def 以下@user = User.find(params[:id])# 通过关系找到关注者 idfollowing_user_ids = @user.passive_relationships.where(created_at: (Time.now - 1.month)..Time.now).map(&:follower_id)# 然后获取关注者@followingurecent = User.where(id:following_user_ids)结尾

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

following.html.erb

<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

解决方案

I'd go for the controller solution.

But the matter is that I will be looking for the relation creation time, not the user (it is user, right, I mean Follower is User model, right?).

So:

def following
    @user = User.find(params[:id])
    # find the follower ids through the relations
    following_user_ids = @user.passive_relationships.where(created_at: (Time.now - 1.month)..Time.now).map(&:follower_id)
    # then get the followers
    @followingurecent = User.where(id: following_user_ids)
end
