MVC4 -- History Log (UPDATE / DELETE)

I like
but it is not for MVC4.

What easy " MVC4 History Log"
solution do you have so the below works ?

 1. user clicks SAVE on Edit.cshtml as normal
 2. below code runs as normal
 3. somehow (via code or MSSQL database trigger) it writes
    only changed values to my "AUDIT_LOG" database table
        public ActionResult Edit(MAINT_WORK_REQ maint_work_req)
            if (ModelState.IsValid)
                db.Entry(maint_work_req).State = EntityState.Modified;
                    if (maint_work_req.OurTechSignature_Date == null)
                        if (Request["Signature_Tech_Checked"].Contains("true"))
                            var context = new UsersContext();
                            UserProfile myProfile = context.UserProfiles.SingleOrDefault(u => u.UserName == User.Identity.Name);
                            maint_work_req.OurTechSignature_Date = myProfile.FirstName + " " + myProfile.LastName + " " + DateTime.Now.ToShortDateString();

                    var context2 = new UsersContext();
                    UserProfile myProfile2 = context2.UserProfiles.SingleOrDefault(u => u.UserName == User.Identity.Name);
                    maint_work_req.LastModifiedDate = DateTime.Now;
                    maint_work_req.LastModifiedBy = myProfile2.FirstName + " " + myProfile2.LastName;

                    .... something like "db.SaveAuditLog()" here

I am not clear what is the question here?

There is not special solution for Audit logs in MVC. Solutions that work anywhere else will work with MVC and Entity Framework.

1. If you use a trigger then that gets executed at the database level and no need to worry about it in your c# code.

2. If you are manually saving to an audit table then simple insert into that table. Wrapping this in a transaction would be handy.

Do you have some sample code for your #2 solution ?

Use "Change Capture" feature in sql server 2008 to do audit.
