ruby-on-rails - 在控制器中创建操作省略了参考字段

问题描述

当我为环境创建客户时，我的 Rails 应用程序出现问题，如果省略environment_id插入语句中的参数，则操作本身存在问题。

这是我的customer.rb模型：

class Customer < ActiveRecord::Base
  belongs_to :environment, inverse_of: :customers

  has_many :all_services, class_name: 'Service'
  has_many :services, inverse_of: :customer

  has_paper_trail ignore: %i[created_at updated_at]
end

这是我的environment.rb模型：

class Environment < ActiveRecord::Base
  has_many :all_customers, class_name: 'Customer', dependent: :destroy
  has_many :customers, inverse_of: :environment

  has_many :all_services, class_name: 'Service', dependent: :destroy
  has_many :services, inverse_of: :environment

  has_many :all_versions, class_name: 'Version', dependent: :destroy
  has_many :versions, inverse_of: :environment

  has_many :all_role_permissions, class_name: 'RolePermission', dependent: :destroy
  has_many :role_permissions, inverse_of: :environment

  has_paper_trail ignore: %i[created_at updated_at]
end

这是customer_controller.rb创建操作：

def create
 if customer_params.permitted?
  render json: Customer.create!(customer_params), status: :ok
 else
  render json: { message: Api::V1::INVALID_PARAMETERS }, status: :bad_request
 end
end

def customer_params
 params.require(:customer).permit(:environment_id, :full_name, :document_type, :document_value, :customer_type)
end

这是服务器日志：

):

我尝试了我能知道的一切，我三重检查了迁移和架构。我还检查了以前项目的活动记录 gem 版本，一切正常。

可能相关的一件事是，该项目在 Angular 中有一个前端。

解决方案

Rails 验证数据库中的环境存在，因为belongs_to它是客户。

您日志中的以下查询正在尝试使用以下内容加载环境ID=1：

Environment Load (0.5ms)  SELECT "environments".* FROM "environments" WHERE "environments"."id" = $1 LIMIT $2  [["id", 1], ["LIMIT", 1]]

在此 Rails 尝试在INSERT没有环境参考的情况下尝试新客户，因为似乎 ID=1 的环境在数据库中不存在。
