Part 61 - Download and Setup Complete Repository Pattern Project ( Asp.net MVC)



Hey guys, hope you have learned a lot of things from this tutorial series. So, I have decided to provide you complete project for no price. Yes you have heard it right. This project has lots of  features included. Here are the list of the things that you can get to learn from this project
  1. Multilayered Architecture
  2. Repository Pattern
  3. Dependency Injection using unity.mvc5
  4. Use of Jquery DataTable
  5. Use of Bootstrap 
  6. CRUD operations 
  7. Use of Partial Views 
  8. Use of Automapper
  9. Use of Entity framework 
  10. Use of ViewModels and DomainModels

You can visit below links to learn how to create multilayered architecture.

 1.  Business Layer 
2. Domain Layer 
3. Data Access Layer 
Here are the steps to download and setup the project 


 Step 1: Download the project zip file Here


step 2: After extracting the zip file, you will get two files. (a) Project solution file and (b) Database script 

step 3: Create a database with name MVCTutorial 
step 4: Execute "MVCTutorial Database script" in SQL server. You can also get the same from  zip file. 
Step 5 :  Update the data source in your connection string in App.config file (MVCTutorial.Repository) and Web.config file (MVCTutorial Web Layer)

 Currently, In below connection string, you will see data source=HP-PC\SQLSERVER2014;  , Just update it to your local system data source. 

 
<connectionStrings>
    <add name="MVCTutorialEntitiesContainer" connectionString="metadata=res://*/MVCTutorialEntities.csdl|res://*/MVCTutorialEntities.ssdl|res://*/MVCTutorialEntities.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=HP-PC\SQLSERVER2014;initial catalog=MVCTutorial;integrated security=True;multipleactiveresultsets=True;application name=EntityFramework&quot;" providerName="System.Data.EntityClient" />
  </connectionStrings>


Step 6: Run your project 
Step 7: You are done

Part 60 - Add Edit Record using Repository Pattern - CRUD




In this tutorial, You will learn about how to perform CRUD operation(Create & Update) over generic repository 

So far, we were creating several Layers but now we will see how the actual repository get setup so that we can use its predefined methods without doing any change into this. In other words, making repository more generic. 

Lets have a quick review of all layers that we created in previous tutorial.

1. Web Layer is your MVC web Project
2.  Business Layer consist the CRUD operation, gets data from Data Access Layer, Manipulate them and finally returns data to the Controller ( Web Layer)
3. Domain Layer consist the Domain Models or Classes that hold the data coming from Data Access Layer. Both Web and Business Layer can use domain models to exchange data.
4. Data Access Layer consist the generic repository methods (generic CRUD operation), Unit of Work( Database Context) and NON Generic repository( User defined repository).



Step 1: Please watch Part 58 (Setup generic repository) before moving to step 2Step 2 : Add EmployeeRepository class into your Repository Layer (MVCTutorial.Repository) and use below code 

A.  EmployeeRepository .cs 

using MVCTutorial.Repository.Infrastructure;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace MVCTutorial.Repository
{
    public class EmployeeRepository:BaseRepository<Employee>
    {
        public EmployeeRepository(IUnitOfWork unitOfWork) : base(unitOfWork) { }

    }
}



Step 2 : In EmployeeBusiness.cs (MVCTutorial.Business layer) class use below code 

 B.  EmployeeBusiness.cs 

using MVCTutorial.Business.Interface;
using MVCTutorial.Domain;
using MVCTutorial.Repository;
using MVCTutorial.Repository.Infrastructure;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace MVCTutorial.Business
{
    public class EmployeeBusiness : IEmployeeBusiness
    {
        private readonly IUnitOfWork unitOfWork;
        private readonly EmployeeRepository empRepository;

        public EmployeeBusiness(IUnitOfWork _unitOfWork)
        {

            unitOfWork = _unitOfWork;
            empRepository = new EmployeeRepository(unitOfWork);
        }
             

        #region

      
        public string AddUpdateEmployee(EmployeeDomainModel empModel)
        {

            string result = "";
            if (empModel.EmployeeId > 0)
            {

                Employee emp = empRepository.SingleOrDefault(x => x.EmployeeId == empModel.EmployeeId);

                if (emp != null)
                {
                    emp.Name = empModel.Name;
                    emp.DepartmentId = empModel.DepartmentId;
                    emp.Address = empModel.Address;

                    empRepository.Update(emp);

                    result = "updated";

                }
            }
            else
            {
                Employee emp = new Employee();

                emp.Name = empModel.Name;
                emp.DepartmentId = empModel.DepartmentId;
                emp.Address = empModel.Address;
                emp.IsDeleted = false;

                var record = empRepository.Insert(emp);

                result = "Inserted";
            }

            return result;
        }

        #endregion

    }
}

Step 4 : Call this method from your controller with appropriate data. 
Step 5 : You are done

            return list;
        }

        #endregion

    }
}
