orm

问题 First, as I know, Entity in DDD is almost same with Value Object except Entity has identity. Every article I have read say same thing that entity id has ORM mapping with any ORM tool. But I don’t want to use ORM mapping in Entity. Instead, I would like to do database operation with Repository Interfaces without mapping. And, in this case, I am stuck on how I should do this. I will explain in my mind with an example below Let’s assume I have a TODO application and there are some questions in

问题 I have this relationship in my Model: public function modulesData($module) { return $this->belongsToMany($module) ->withTimestamps(); } What I want is to eagerload a dynamic relation of my model. But how can I do this? I use this code to eagerload my relation, but how can I add the parameter $module ? $model->with(['modulesData'])->get(); Thanks for reply. 回答1: Consider the following: Define the fallback function to your Model: public function __call($name, $arguments) { if (strpos($name,

问题 I've just started using Node.js ORM Sequelize in my application. So far I've defined database models in the same file and used them in my controller files to do basic operations. Here is how I defined Models: var sqlize = require("sequelize"); var sq = new sqlize('test', 'root', 'root', { host: 'localhost', dialect: 'mysql', pool: { max: 5, min: 0, idle: 10000 } }); function services(){ var ser = sq.define('services',{ idservices: { type: sqlize.INTEGER, autoIncrement: true, primaryKey: true

问题 I have two entities where one has a one to many relationship to the other.

问题 In most of my projects I use nHibernate + Fluent mapping and recently I've started to play around with Dapper to see if I can move read operations to it. I follow DDD approach so my domain entities do not have any public setters. For example: public class User { private int _id; private string _name; private IList<Car> _carList; protected User(){} // Fluent Mapping public User(string id, string name) { // validation // ... _id = id; _name = name; } public int Id{ get {return _id;} } public
