repository-pattern

问题 I'm a big fan of using the Repository pattern to return IQueryable<T> objects. I then let my services layer determine what does what (eg. filter by XXX, order by YYY, project into ABCD, etc). But I've got some hardcore DB stuff, so I've got it all wrapped up into a Stored Procedure . Works fine. I know EF can execute stored procs .. but I'm not sure how this fits into a Repository Pattern data layer. Does anyone have any examples / suggestions ? Do i let the repository method execute the

问题 I'm trying to streamline my existing repos by using a generic repo I can subclass from. The problem is that I can't figure out how to write a few of my base class methods. I currently have: public interface IRepository<T> : IDisposable where T : class { IQueryable<T> GetAll(); T GetSingle(int id); T GetSingle(string slug); void Save(T entity); } public class HGRepository<T> : IRepository<T> where T : class { protected HGEntities _siteDB; protected IObjectSet<T> _objectSet; public HGRepository

问题 This is in a web application environment: An initial request is able to successfully complete, however any additional requests return a "Session is Closed" response from the NHibernate framework. I'm using a HttpModule approach with the following code: public class MyHttpModule : IHttpModule { public void Init(HttpApplication context) { context.EndRequest += ApplicationEndRequest; context.BeginRequest += ApplicationBeginRequest; } public void ApplicationBeginRequest(object sender, EventArgs e

问题 I'm trying to figure out how to use this orderBy parameter. I am not sure what I am suppose to pass in. http://www.asp.net/mvc/tutorials/getting-started-with-ef-using-mvc/implementing-the-repository-and-unit-of-work-patterns-in-an-asp-net-mvc-application public virtual IEnumerable<TEntity> Get( Expression<Func<TEntity, bool>> filter = null, Func<IQueryable<TEntity>, IOrderedQueryable<TEntity>> orderBy = null, string includeProperties = "") { IQueryable<TEntity> query = dbSet; if (filter !=

问题 I use Repository pattern (and linq2sql as data access) and have, for example, ProductsRep and CustomersRep. In very simple scenario db has two tables - Produsts (ProductID, CustomerID, ProductName, Date) and Customer (CustomerID, FirstName, LastName). Each repository provide methods to create, update, delete and get specific model object, and, may be, some filters. But if I want to query all customers that buy specific product by product name, I have to get ProductID of this product using

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 6 years ago . I am working on implementing Repository Pattern and UnitOfWork from last few days, which I have completed to upto good extend, I believe. I am sure there are plenty of ways to implement that but what I am interesting to find best approach for that. I am taking very simple

问题 I'm trying to setup a base Repository class that can use the Entity Framework edmx model context. The problem I'm having is that I need to find an interface that the EF EDMX object context implements so I can pass to the constructor via dependency injections. I've got around this before by using a DataFactory that creates it and stores it in the HttpContext but that kills the ability to unit test. Any help would be appreciated. Thanks! public abstract class BaseRepository<T> where T :

问题 I've gone through quite a few articles on the repository pattern and had some questions. I'm trying to implement this in a ASP.NET 4.0 application. The architecture is a layered architecture with a Presentation Layer, Business Layer and Data Layer. From this article, http://www.primaryobjects.com/CMS/Article108.aspx I have created the MYSQLRepository (DataLayer) public class MySQLRepository:IOrderRepository { public List<Order> GetOrders() { List<Order> orders = new List<Order>(); orders.Add

问题 So after much reading I've now come to the realization that complex reporting functions do not belong in your typical Repository and that there needs to be some kind of dedicated "Finder" which returns read only objects to be used in reporting. What I'm unclear on is where the "Finder" classes, as well as their associated ReadModel classes are supposed to go inside my project? Are the finders like repositories in that you have an interface for the finder inside the infrastructure assembly

问题 Namespaces omitted for brevity... I have written the following service provider and registered in config/app.php: class OfferServiceProvider extends ServiceProvider { public function register() { $this->registerLossControlManager(); } protected function registerLossControlManager() { $this->app->bind('LossControlInterface', 'LossControl'); } } Here is my LossControlInterface interface LossControlInterface { /** * @param int $demandId * @param float $offerTotal * @param float $productTotal *
