Sql Server Management Studio free awesome addons

The two addons that I can not live without in Sql Server and that, more , are free :

  1. SSMS Tools Pack – now 1.7.5.1 , http://www.ssmstoolspack.com/Download
  2. SQL Search – now1.0 http://www.red-gate.com/products/SQL_Search/

 

The SSMS Tools Pack maintains a history of your commands . More, it saves on the C:\SSMSTools\SQLQueryActionLog

ASP.NET MVC , ORM and ViewModels

Since I am active on asp.net/mvc I find many peoples asking about

  1. One to many relationship .
  2. Dropdownlist
  3. How to use MVC with other ORM frameworks instead of Linq To Sql(L2S) ?
  4. What is a ViewModel and what is his purpose ?

For answering, I have made a small application with MVC2 in order to detail my answer.

First the problem :

You have Employees and Department.Each Employee belongs to an Department (let’s forget the fact that the employee can belong for a final date to the Department or any other life ideas)

The request is to create and view Employees .(forget delete,update – if I will have time and/or by general request , I will do this also this)

The database:

image

The beginning of the application :

First Layer , Data Access Layer
I use EF 3.5 (not 4.0 with POCO style – because is not ready yet) and make an edmx file and let EF put his classes.
You can use also ADO.NET with StoredProc, L2S, NHibernate or any other ORM you want.
Second Layer,Business Logic :
This is the layer where the logic should intervene (e.g., the name should be not null ).

Here is the list for Employee :

namespace BusinessLogic

{

    /// <summary>

    /// TODO : add IDataErroInfo in order to validate

    /// TODO : add the department

    /// </summary>

    public class Employee

    {

        public long ID;

        public string Name { get; set; }

        public Department Department{ get; set; }

        public void SaveNew()

        {

            //TODO : validate before save

            //TODO : automapper

            using (DAL_EF.testsEntities te = new DAL_EF.testsEntities("name=myconnection"))

            {

                DAL_EF.Employee e = new DAL_EF.Employee();

                e.Name = this.Name;

                //TODO : what if dept. deleted ?

                e.Department =te.Department.Where(d=>d.ID== this.Department.ID).FirstOrDefault();

                te.AddToEmployee(e);

                te.SaveChanges();

            }

        }

    }

    public class EmployeeList : List<Employee >

    {

        public void Load()

        {

            using (DAL_EF.testsEntities te = new DAL_EF.testsEntities("name=myconnection"))

            {

                foreach (var emp in te.Employee.Include("Department"))

                {

                    //TODO : use automapper

                    Employee e=new Employee() { ID = emp.ID, Name = emp.Name };

                    e.Department=new Department(){ ID=emp.Department.ID,Name=emp.Department.Name};

                    this.Add(e);

                }

            }

        }

    }

}

Please pay attention for Load procedure in EmployeeList : it uses the first layer, DAL, but it can use any ORM framework.

Third layer, ViewModel:

Because all the views for employees will need a select list for department ( either for sorting, creating or updating) I have put a base ViewModel class that retrieves the list of Departments:

namespace MVCAppEmp.Classes
{
    public class ViewModelEmployee
    {
        public static SelectList ListOfDepartments
        {
            get
            {
                //TODO : put this into cache to not load every time
                DepartmentList dl = new DepartmentList();
                dl.Load();
                return dl.SelectFromList(x => x.ID.ToString(), y => y.Name);
            }
        }
    }
    public class ViewModelEmployeeCreate : ViewModelEmployee
    {
        public Employee emp=new Employee();
    }
    public class ViewModelEmployeeList : ViewModelEmployee
    {
        public EmployeeList employees;
        public void Load()
        {
            employees = new EmployeeList();
            employees.Load();
        }
    }
}


Fourth Layer , MVC itself – view and controller :

<% =Html.ValidationSummary() %>
<% using (Html.BeginForm())
   { %>
    <h2>Create</h2>
    List of departments :
    <% =Html.DropDownList("DepartmentID", MVCAppEmp.Classes.ViewModelEmployee.ListOfDepartments)%>
    <%=Html.EditorFor(model => model.emp)%>
<input type="submit" value="create" />
<%} %>

and the controller

// POST: /Employee/Create
       // TODO: make a binding for employees
       [HttpPost]
       public ActionResult Create(Employee emp,long DepartmentID)
       {
           try
           {

               emp.Department = new Department() { ID = DepartmentID };
               emp.SaveNew();
               return RedirectToAction("Index");
           }
           catch(Exception ex)
           {
               ModelState.AddModelError("", ex.Message);
               return View(new ViewModelEmployeeCreate(){emp=emp});
           }
       }

So to answer the questions :

  1. One to many relationship – easy to do, most difficult to program
  2. Dropdownlist – easy – just transform a list into a select list, provided you have all data belongs
  3. How to use MVC with other ORM frameworks instead of Linq To Sql(L2S) ? Does not matter ! Just create your BusinessLogic and use that ORM!
  4. What is a ViewModel and what is his purpose ? To fill the data for GUI that BusinessLogic does not comply and transfer data to BusinessLogic. Reciprocally too!

You will find attached the application and the sql to create the database :

For MVC2  /MVC 3

For MVC 4

http://msprogrammer.serviciipeweb.ro/wp-content/uploads/ASP.NETMVCORMandViewModels_135E/empMVC4.zip

What to do next, in order to familiarize yourself :
1. Make the update of the employees .Create view, save.
2. Filter the list of the employees on department. Search for all employees beginning with A that belong to IT department.
3. Search for TODO’s : there are part of other tutorials – but it will help you in MVC (and other!) development

ASP.NET MVC Extensions Methods

These are my extensions.

  1. Not display dropdownlist if the Select list is null
    public static MvcHtmlString DropDownListNull(this HtmlHelper html, string Name, SelectList select, object htmlAttributes)
    {
    
    if (select == null)
    return MvcHtmlString.Empty;
    else
     return html.DropDownList(Name, select, htmlAttributes);
    
    }
    
    
  2. Transform Enum to SelectList
    #region enum to list
            private static List<KeyValuePair<long, string>> FromEnum(this Type e)
            {
                List<KeyValuePair<long, string>> kvp = new List<KeyValuePair<long, string>>();
                foreach (var s in Enum.GetValues(e))
                {
                    kvp.Add(new KeyValuePair<long, string>((int)s, s.ToString()));
                }
                return kvp;
            }
            public static SelectList ToSelectList(this Type enumObj)
            {
    
                return new SelectList(enumObj.FromEnum(), "Key", "Value");
    
            }
            #endregion
    
  3. Transform Generic list into a SelectList
                  #region Generic List to SelectItem
            public static SelectList SelectFromList<TItem>(this List<TItem> values,
                Expression<Func<TItem, string>> key, Expression<Func<TItem, string>> value)
            {
                var Key = key.Compile();
                var Value = value.Compile();
                List<KeyValuePair<string, string>> kvp = new List<KeyValuePair<string, string>>(values.Count);
                values.ForEach(item =>
                    kvp.Add(new KeyValuePair<string, string>(Key.Invoke(item), Value.Invoke(item))));
    
                return new SelectList(kvp, "Key", "Value");
    
            }
            #endregion
    
    
  4. Display pager control
    #region paged list control
            //after http://geekswithblogs.net/nuri/archive/2009/08/05/mvc-paged-list.aspx
            /// <summary>
            /// Shows a pager control - Creates a list of links that jump to each page
            /// </summary>

            /// <param name="actionName">Name of the action on the controller.</param>
            public static void ShowPagerControl(this ViewPage page, BasePagedListImplementation pagedList, string formatUrl)
            {
                HtmlTextWriter writer = new HtmlTextWriter(page.Response.Output);
                if (writer != null)

                            writer.RenderBeginTag(HtmlTextWriterTag.A);
                        }
