Question

我有一个Availability模型，我想发送一个API发布请求以一次创建多个可用性。

我偶然发现了这个post on medium，我很激动，它可以解决我的问题，但是没有解决，因为在我通过API发送请求时，作者使用的是Rails表单模板。

我对documentation进行了进一步研究，发现了一种创建多个记录的方法，在那里也尝试了该方法，但是对我不起作用。

这是我的控制器代码。 create方法和availability_params方法。

module API
  module V1
    class AvailabilitiesController < ApiController
      def create
        availability = Availability.new(availability_params)
        availability.tutor = current_user

        availability.start_time = DateTime.parse("#{availability_params[:day_of_the_week]} #{availability_params[:start_time]}")
        availability.end_time = DateTime.parse("#{availability_params[:day_of_the_week]} #{availability_params[:end_time]}")

        if availability.start_time < DateTime.current && availability.end_time < DateTime.current
          availability.start_time += 1.week
          availability.end_time += 1.week
        end

        if availability.save
          render json: {
            availability: availability,
            message: 'Your availability was created successfully.'
          }
        else
          render json: { message: 'There was a problem creating your availability.', errors: availability.errors }, status: :bad_request
        end
      end

      def destroy
        Availability.where(id: params[:ids]).destroy_all
      end


      def availability_params
        params.require(:availability).permit(:day_of_the_week, :start_time, :end_time).tap do |availability_params|
          availability_params.require([:day_of_the_week, :start_time, :end_time])
        end
      end

    end
  end
end

使用axios从前端发出的请求如下所示：

axios.post('/api/v1/availabilities', { availability: payload })

destroy函数还会发送这种类型的请求：

axios.delete('/api/v1/availabilities', { params: { ids: payload } })

该请求的示例输出在发送后如下所示：

web_1        | Started POST "/api/v1/availabilities" for 172.18.0.1 at 2018-10-29 18:07:27 +0000

web_1        |   User Load (1.0ms)  SELECT  "users".* FROM "users" WHERE "users"."id" = $1 ORDER BY id LIMIT $2  [["id", 1], ["LIMIT", 1]]

我到底在做什么错？任何建议将不胜感激，谢谢。

您已经关闭。如果查看日志，则可以看到params [：availability]是一个数组，但是您的robot.respond(!(/command1/, /command2/, /command3/, etc.) function (msg) { msg.reply('Returned message') })方法将其作为代表一个项目的属性的简单哈希值进行处理。

像这样循环播放：

create

通过Rails API调用添加多个记录
