Question

我不确定为什么这不允许当前用户取消关注用户。当＆＃34;取消关注＆＃34;单击按钮，页面被路由到/ friendships？friend_id = 2并且此错误消息：没有路由匹配[DELETE]＆＃34; / friendships＆＃34;出现

_user.html.erb

 <%= link_to "Unfollow", friendships_path(friend_id: user.id), method: :delete, data: { confirm: "Are you sure?" }, class:"btn btn-md btn-danger" %>

友谊控制器

def destroy
  @friendship = Friendship.find_by(id: params[:id])
  @friendship.destroy
  flash[:notice] = "Removed friendship."
  redirect_back fallback_location: root_path
end

的routes.rb

resources :friendships, only: [:create, :update, :destroy]

schema.rb

  create_table "friendships", force: :cascade do |t|
    t.integer "user_id"
    t.integer "friend_id"
    t.boolean "accepted", default: false
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
  end

你可以尝试使用单数friendship_path而不是复数形式（friendships_path）

<%= link_to "Unfollow", friendship_path(current_user.friendships.find_by_friend_id(u‌ser.id)), :method => :delete, data: { confirm: "Are you sure?" }, class:"btn btn-md btn-danger" %>

Ruby on Rails：取消关注用户
