Using EqMvcDemoEF sample with your own DB context

Demo version of EasyQuery contains EqMvcDemoEF sample project which demonstrates how to use our library with Entity Framework (code first approach). This article contains a brief instruction how to modify that sample project to make it work with your own context class (instead of NorthwindContext class used in our sample).

1. Add your own DbContext class into the project

Current DBContext is placed in Models\TestContext.cs file. Remove that file from the project and add your own context class. Don't forget to change the namespace to Korzh.EasyQuery.Mvc.Demo.Models or add using for your own namespace into EasyQueryController.cs Let's suppose your context class is named MyContext

2. Modify Web.Config

EqMvcDemoEF uses SQL Server CE provider. If you plan to use another database type - you need to make modifications in entityFramework section of Web.Config file.

3. Changes EasyQueryController class

Finally, you need to modify the constructor of EasyQueryController class to make it work with your context instead of Northwind. Simply replace all inclusions of NorthwindContext with the name of your context class.

Here is how the modified constructor may look like (we guessed your context class is called MyContext):

public EasyQueryController() {
    eqService = new EqServiceProviderDb();
    eqService.ModelLoader = (model, modelName) => {
        model.LoadFromDBContext(typeof(MyContext), DbContextOptions.IncludeComplexTypesInParentEntity);
    eqService.Paging.Enabled = true;
    eqService.SessionGetter = key => Session[key];
    eqService.SessionSetter = (key, value) => Session[key] = value;
    var context = new MyContext();
    //For Entity SQL use the following settings for connection and formats
    var connection = ((System.Data.Entity.Infrastructure.IObjectContextAdapter)context).ObjectContext.Connection;
    eqService.Connection = connection;
