Question

我正在尝试按照以下链接构建友谊系统：如何在Rails 3中为社交网络应用程序实现友谊模型？但缺乏一点。我能够建立一种关系但是我不确定如何执行以下操作：取消，拒绝，接受。

所以，让我说我试图取消关系，我在待处理中执行以下操作，调用我执行的操作：

<% @customer.pending_friends.each do |pf| %>
  <%= link_to pf.incomplete_name, cancel_friendships_path(:friend_id => pf), :method => :post  %><br />
<% end %>

这里是取消的控制器

  def cancel
    @customer = current_customer
    @friend = Customer.find(params[:friend_id])
    if @customer.pending_friends.include?(@friend)
      Friendship.breakup(@customer, @friend)
      flash[:notice] = "Friendship Canceled"
    else
      flash[:notice] = "No Friendship request"
    end
    redirect_to root_url
  end

这里是我的分手功能

  # Delete a friendship or cancel a pending request.
  def self.breakup(customer, friend)
    transaction do
      destroy(find_by_customer_id_and_friend_id(customer, friend))
      destroy(find_by_customer_id_and_friend_id(friend, customer))
    end
  end

但是，点击取消链接时，我收到了无路由错误。我做错了什么？

请求

resources :friendships do
    collection do
      get 'cancel'
      get 'decline'
    end
  end
  resources :friendships

问题是你的路线中有：

get 'cancel'

但是您的取消链接正在发布帖子请求，而非get：

<%= link_to ..., ..., :method => :post %>

我个人认为它应该是删除请求。

在您的路线中：

delete 'cancel'

在您看来：

<%= link_to pf.incomplete_name, cancel_friendships_path(:friend_id => pf), :method => :delete %>

您的代码可能还有其他问题，但这是您必须解决的一件事。
