问:

我正在 RoR 项目中实现 FullCalendar,当我尝试更新一行时出现此错误:

PATCH http://127.0.0.1:3000/events 404 (Not Found)

这是当我单击事件时更新行的 Ajax 调用:

$.ajax({
                        type: 'PATCH', // Use PATCH or PUT depending on your Rails routes
                        url: '/events/' + eventId, // Adjust the URL to your Rails route

                        data: {
                            event: {
                                title: 'updatedTitle',
                                start_date: 'updatedStartDate',
                                end_date: 'updatedEndDate',
                                description: 'updatedDescription'
                            }
                        },
                        beforeSend: function(xhr) {
                            xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'));
                        },
                        success: function(response) {
                            if (response.status === 'success') {
                                // Update the event data in FullCalendar
                                arg.event.setProp('title', updatedTitle);
                                arg.event.setStart(updatedStartDate);
                                arg.event.setEnd(updatedEndDate);
                                arg.event.setExtendedProp('description', updatedDescription);

                                // Close the modal
                                $('#eventModal').modal('hide');

                                // Display a success message (you can use Swal or other methods)
                                Swal.fire({
                                    text: 'Event updated successfully',
                                    icon: 'success',
                                    buttonsStyling: false,
                                    confirmButtonText: 'Ok, got it!',
                                    customClass: {
                                        confirmButton: 'btn btn-primary',
                                    }
                                });
                            } else {
                                // Handle the case where the update failed
                                Swal.fire({
                                    text: 'Event update failed: ' + response.message,
                                    icon: 'error',
                                    buttonsStyling: false,
                                    confirmButtonText: 'Ok, got it!',
                                    customClass: {
                                        confirmButton: 'btn btn-primary',
                                    }
                                });
                            }
                        },
                        error: function(error) {
                            console.log('AJAX request to Rails failed.');
                            console.log(error)
                        },
                    });

我console.logged my eventId,并且它已正确实现(其值为76)。我不明白为什么 Ajax 调用使用的 url 是 url: '/events/'

这是我的routes.rb文件:

Rails.application.routes.draw do
  resources :telephones


  get 'home/index'
  resources :tickets
  resources :imprimantes
  resources :voitures
  resources :telephones
  resources :events

  resources :events do
    collection do
    post 'import_ics'
    get 'export_ics'
  end
end

  # Define a route for updating events using PATCH
  patch '/events/:id', to: 'events#update', as: 'update_event'

  resources :google_calendar, only: [:index, :create, :update, :destroy]


  root 'home#index'

  # Defines the root path route ("/")
  # root "posts#index"
end

而更新功能:

def update
      @event = Event.find(params[:id])
      if @event.update(event_params)
        redirect_to events_path
      else
        render 'edit'
      end


 def event_params
  params.require(:event).permit(:title, :start_date, :end_date, :description)
end
    end

我错过了什么?

你能为这个请求添加 Rails 日志吗?
2赞 Ben Trewern 11/15/2023
运行以查看是否有正确的路由并发布输出。bin/rails routes | grep events

更新后是否重新启动服务器?config/routes.rb

根据 Rails 日志,看起来您的 JS 触发了一个有效的请求并更新了一条记录。问题是,在成功更新后的控制器中,您可以重定向到events_path

if @event.update(event_params)
  redirect_to events_path
else
  render 'edit'
end

你能尝试添加一段逻辑来区分 mime 类型的请求吗?

像这样:

def update
  @event = Event.find(params[:id])

  respond_to do |format|
    if @event.update(event_params)
      format.html { redirect_to events_path }
      format.json { render json: { status: :success } }
    else
      format.html { render 'edit' }
      format.json { render json: { status: :unprocessable_entity } }
    end
  end
end

链接到源 Mime 响应

此外,您应该在 ajax 调用中添加一个 Accept 标头。您的 ajax 调用应如下所示:

$.ajax({
  type: 'PATCH',
  url: '/events/1',
  headers: {
    Accept: "application/json"
  },
  data: {
    event: {
      title: 'new_title'
    }
  },
  beforeSend: function(xhr) {
    xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'))
  },
  success: function(response) {
    console.log(response)
    // Handle your response
  },
  error: function(response) {
    console.error(response)
    // Handle your error
  }
})

我尝试了此代码,并遇到了同样的错误

我明白了,尝试在ajax调用中添加一个标题'Accept: “application/json”'。您还应该将控制器中的格式从 js 更改为 json。

完美,它有效!谢谢
