mvc entity framework : login using a database - asp.net-mvc-2

Question

I have created a database in Microsoft sql server express. I need to be able to login on Mvc 2 app, using my database ( not the one existing on AcountController meaning MembershipService )
I just need to replace MemeberAhipService with my database. How can I do that ( i'm using entity framework code first ) . I don't need to create a model in visual studio. I have the usermodel, userContext: Db . I think i need repository also. Can anyone show me an example, of tell me the steps ?

Answer 1

You can create your own MembershipService.
Example:
New MembershipService.cs (or whatever you want)
public class MembershipService
{
public bool IsUserValid(string username, string password)
{
var db = new DatabaseContext();
var user = db.GetUser(username, password);
// Or however you want to get your data, via Context or Repository
return (user != null);
}
}
New FormsClass.cs
public class FormService
{
public void SignIn(string username, List&ltstring> roles)
{
FormsAuthenticationTicket authTicket = new
FormsAuthenticationTicket(1, // Version
username, // Username
DateTime.Now, // Creation
DateTime.Now.AddMinutes(30), // Expiration
false, // Persistent
string.Join(",", roles.ToArray())); // Roles
string encTicket = FormsAuthentication.Encrypt(authTicket);
HttpContext.Current.Response.Cookies.Add(new HttpCookie(FormsAuthentication.FormsCookieName, encTicket));
GenericIdentity id = new GenericIdentity(username);
HttpContext.Current.User = new GenericPrincipal(id, roles.ToArray());
}
}
In Global.asax:
protected void Application_PostAuthenticateRequest(object sender, EventArgs e)
{
HttpCookie authCookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName];
if (authCookie != null)
{
string encTicket = authCookie.Value;
if (!String.IsNullOrEmpty(encTicket))
{
FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(encTicket);
FormsIdentity id = (FormsIdentity)Context.User.Identity;
var roles = ticket.UserData.Split(",".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);
GenericPrincipal prin = new GenericPrincipal(id, roles);
HttpContext.Current.User = prin;
}
}
}
