Question

我正在尝试允许用户通过关注者宝石来关注或取消关注用户。这是我的表演视图：

     <tbody>
                      <% @runs.each do |run| %>
                          <td><%= run.user.try(:username) %><p> 
                            <% if current_user.following?(@user) %> 
                            <%= link_to "Unfollow", unfollow_user_path(@user.username), method: :delete %></p>
                            <% else %>  
                            <%= link_to "Follow", follow_user_path(@user.username), method: :post %> </td> 
                            <% end %>
                          <td><%= run.Run_Type %></td>
                          <td><%= run.Location %></td>
                          <td><%= run.Start_Time %></td>
                          <td><%= run.Pace %></td>
                          <td><%= run.Miles %></td>
                          <td><%= run.Run_Date %></td>
                          <td><%= link_to 'Show', run %></td>
                          <% if run.user == current_user %>
                          <td><%= link_to 'Edit', edit_run_path(run) %></td> 
                          <td><%= link_to 'Destroy', run, method: :delete, data: { confirm: 'Are you sure?' } %></td>
                           <% end %>
                        </tr>
                      <% end %>
                    </tbody>
                  </table>

和我的路线：

  resources :users, only: :show, param: :username do
member do
  post 'follow', to: 'follows#create'
  delete 'unfollow', to: 'follows#destroy'
end

结束

和我的控制器：

   class FollowsController < ApplicationController
  before_action :authenticate_user!

  def create
    user = User.find_by(username: params[:username])
    Follow.create(followable: user, follower: current_user)
    redirect_to user_path(user.username), notice: "Successfully followed user"
  end

  def destroy
    user = User.find_by(username: params[:username])
    Follow.find_by(followable: user, follower: current_user).destroy
    redirect_to user_path(user.username), notice: "Successfully unfollowed user"
  end
end

最终我的模型：

   class Follow < ApplicationRecord

  extend ActsAsFollower::FollowerLib
  extend ActsAsFollower::FollowScopes

  # NOTE: Follows belong to the "followable" and "follower" interface
  belongs_to :followable, :polymorphic => true
  belongs_to :follower,   :polymorphic => true

  def block!
    self.update_attribute(:blocked, true)
  end

end

单击“关注用户”时，用户会收到“成功关注用户”的通知，但是预期的操作应该是该链接然后显示“取消关注用户”，但是不会发生。

acts_as_follower rubygems版本0.2.1已于2013年过时。您需要从以下位置更改gemfile行：

gem 'acts_as_follower'

到

gem 'acts_as_follower', github: 'tcocca/acts_as_follower', branch: 'master'

或者您也可以在这里接受我的PR：https://github.com/westche/sample_app/pull/1

取消关注用户不起作用：充当关注者宝石
