从昨天起,我的生产应用程序开始ActiveRecord::ImmutableRelation在我的整个应用程序的一些查询中提出!

我无法想象如何给出每个错误的确切上下文,因为这个错误发生在我的应用程序的随机位置!我无法模拟在Rails控制台中调用相同代码块的错误,仅在生产环境中的控制器中。

我们不会更改任何查询,我会认为这可能是数据库配置中的错误或某些更改(?)。有人已经收到此错误吗?知道我可以搜索什么吗?

细节控制器代码(我省略了一些企业的模型名称):

# frozen_string_literal: true
class DetailsController < V2::ApplicationController
  def show
    model = Model.find(params[:pricing_id])
    details = model.details.order(:position)
    details.each { |detail| detail.model = model }
    Detail.cascade_formula_arguments(details, params)
    details = details.select(&:available?)

    render json: details, each_serializer: ::V2::DetailSerializer
  end
end

用户回答回答于

除非您希望修改数据,否则我建议将其映射到哈希数组......但不确定Detail.cascade_formula_arguments(details, params)是做什么的,所以这是猜测。

我会尝试将数据转换为哈希而不是活动记录对象,除非你真的试图修改它们,所以像这样:

details.each { |detail| detail.model = model }
details = details.map(&:as_json)
