充当追随者在前端不起作用

Question

我安装了 Acts_as_follower。我在我的控制台中使用了文档中的方法，所以我确定用户 1 在 ActiveRecord 中跟随用户 2（使用设计），并且在 users/show.html.erb 页面的前端它显示了我实现的按钮的适当 follow/unfollow 部分。不幸的是，每当我按下 follow/unfollow 按钮时，都没有任何变化或发生。

我认为这是路由问题，但想知道是否有人知道为什么没有任何反应。我已从我的控制台确认缺少操作。

user.rb

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

   acts_as_followable
   acts_as_follower

   has_attached_file :image, :styles => { :medium => "300x300>", :thumb=> "100x100>" }
    validates_attachment_content_type :image, :content_type => /\Aimage\/.*\Z/

   has_many :articles
   has_many :comments
end

routes.rb

Rails.application.routes.draw do
  devise_for :users
  resources :articles do
    member do
      put "Like",   to: "articles#upvote"
      put "Disike", to: "articles#downvote"
    end
    resources :comments
  end

  resources :users do
    get :follow
    get :unfollow
  end

  root 'welcome#index'

users_controller.rb

class UsersController < ApplicationController
    def show
        @user = User.find(params[:id])
        @user_articles = @user.articles
    end

    def create
    @user = User.find(params[:user_id])
    current_user.follow(@user)
  end

  def destroy
    @user = User.find(params[:user_id])
    current_user.stop_following(@user)
  end
end

followers_controller.rb

class FollowsController < ApplicationController
    before_action :authenticate_user!
  respond_to :js

  def create
    @user = User.find(params[:user_id])
    current_user.follow(@user)
  end

  def destroy
    @user = User.find(params[:user_id])
    current_user.stop_following(@user)
  end
end

users/show中的按钮。html.erb

<div class="follow">
  <% if @user.followed_by?(current_user) %>
    <%= form_tag user_unfollow_path(user_id: @user.id), method: :post, remote: true do %>
      <center><%= button_tag 'unfollow', class: 'btn btn-primary' %></center>
    <% end %>
  <% else %>
    <%= form_tag user_follow_path(user_id: @user.id), method: :post, remote: true do %>
      <center><%= button_tag 'follow', class: 'btn btn-success' %></center>
    <% end %>
  <% end %>
</div>
</div>

Answer 1

你的怀疑是对的，确实是路由问题。但是你的努力得到了 A，因为文档没有讨论前端，你能走到这一步是件好事 :)

您的路线应该更像：

resources :users do
  post :follow, to: "#followers#create"
  delete :unfollow, to: "followers#destroy"
end

注意unfollow是调用destroy，所以按照惯例是delete，按照惯例create应该是post.

鉴于此，请确保您的视图如下所示：

<div class="follow">
  <% if @user.followed_by?(current_user) %>
    <%= form_tag user_unfollow_path(user_id: @user.id), method: :delete, remote: true do %>
      <center><%= button_tag 'unfollow', class: 'btn btn-primary' %></center>
    <% end %>
  <% else %>
    <%= form_tag user_follow_path(user_id: @user.id), method: :post, remote: true do %>
      <center><%= button_tag 'follow', class: 'btn btn-success' %></center>
    <% end %>
  <% end %>
</div>
