Stampings Algorithm in ASP.NET MVC LINQ Entity Framework

Stampings Algorithm in ASP.NET MVC LINQ Entity Framework - c#

As the title says, I'am trying to write an algoritm with these conditions:
Each employee has a flextime balance which is initially zero.
If the total time of all stamp ins and stamp outs in a working day exceeds 8 hours, the flexitime balance listed with the prolonged time , and the same principle applies to the deficit.
Flextime balance is listed with all the time stamped on the days that are relieved of work.
If no stamps occurred on a working day then the flextime balance is not affected.
There are two tables im having in the database: NonWorkingDays and Stampings.
NonWorkingDays contains only of one column which is: "Days (DateTime)".
Stampings contains of four columns: "Id (Int) (PK), UserId (Int), Timestamp (DateTime), StampingType (value "in" and value "out")
This is what I wrote so far -
Model:
public class FlexModel
{
public List<User> Users { get; set; }
public List<Stamping> Stampings { get; set; }
public decimal FlexTime { get; set; }
}
View:

}
So this is not working for me, I get the value of Flex to display 0.
Help would be appreciated!

DropDownListFor post value NULL to database

I have a Course Table and a Hole Table in SQL. There is a foreign Key in the hole Table that is set to the CourseId.
This is so that when I create a hole I can assign it to the relevant course.
In my View I have a dropdownlistfor that has a list of courses to select from when creating the hole. However when I try and post back the values the courseID does not post back.
HoleViewModel
// GET: HoleViewModels/Create
public ActionResult Create()
{
var dbcourse = db.Course.ToList();
//Make selectlist, which is IEnumerable<SelectListItem>
var courseNameDropdownList = new SelectList(db.Course.Select(item => new SelectListItem()
{
Text = item.CourseName.ToString(),
Value = item.CourseId.ToString()
}).ToList(), "Value", "Text");
// Assign the Selectlist to the View Model
var viewCourse = new HoleViewModel()
{
Course = dbcourse.FirstOrDefault(),
// The Dropdownlist values
CourseNamesDropdownList = courseNameDropdownList,
};
return View(viewCourse);
}
// POST: HoleViewModels/Create
// To protect from overposting attacks, please enable the specific properties you want to bind to, for
// more details see https://go.microsoft.com/fwlink/?LinkId=317598.
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "HoleId,HoleNumber,Par,Length,StrokeIndex,CourseId")] HoleViewModel holeViewModel)
{
if (ModelState.IsValid)
{
db.HoleViewModels.Add(holeViewModel);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(holeViewModel);
}
The Create.cshtml
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>HoleViewModel</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })

#Html.ValidationMessageFor(model => model.CourseId, "", new { #class = "text-danger" })
</div>
</div>
So when the holeview posts back holeNumber, Par, Length, StrokeIndex, CourseID. it passes all data into the hole table other than the courseId which it posts a null.
What am I missing from the POST to get the CourseId to be entered in the Database.

The problem is that you returning "view", but you do not supply the "model" in which the engine can bind them together, thus the default is null.
return View("Index");
should be
return View("Index", carlist);

You are not passing the retrieved carlist model to the view. Therefore the view does not have access to the model and is not able to fill in the form.
// GET: CarAuction/Edit/5
public ActionResult Edit(int id= 3)
{
CarList carList = db.CarLists.Find(id);
// Change this:
return View(carList);

Your view is strongly typed to a CreateStudent class and the view code is using Model.Genders collection property when you use the DropDownListFor helper method. But in your http post action, you are calling the return View() method without passing a valid CreateStudent object and in another case without populating the Genders property. So when razor executes the view code, the model value is null ( because you did not pass anything to the view)
You need to set the Genders property again before returning the posted view model back to the view.
[HttpPost]
public ActionResult Create(CreateStudent student)
{
var genderList = new List<SelectListItem>()
{
new SelectListItem { Text = Constants.Gender.Boy, Value = Constants.Gender.Boy},
new SelectListItem { Text = Constants.Gender.Girl, Value = Constants.Gender.Girl},
};
if (ModelState.IsValid)
{
var result = _student.Insert(mappedStudent);
if (result)
{
return RedirectToAction("Index");
}
else
{
student.Genders = genderList;
TempData["Message"] = "Failed to create new student";
return View(student); // Passing the object here to view
}
}
//Model validation fails. Return the same view
student.Genders = genderList;
return View(student);
}
}
Also there no need for an extra casting. Model.Genders is of type List<SelectListItem>
#Html.DropDownListFor(o=>o.Gender,Model.Genders, new { #class = "form-control" })

How to Insert Multiple Rows in One Table? (MVC 5 ASP.NET)

I would want to insert multiple entries in my table called 'sibling' using it's Create Method (which I generated automatically using Scaffolding methods). I already made the form dynamic in adding the fields. However, when I click on the Submit button it only gets the first entry.
I sort of have an idea by implementing 'foreach' in the said method but I can't seem to find an answer that is spot on. Especially for my case I just want to modify the Create Method for 'sibling' which was generated automatically (if there is such a way without having to create a new method - but if not I am fine with a different approach as well).
This is my SiblingController:
public ActionResult Create(int id)
{
var sib = new sibling();
sib.child_id = id;
return View(sib);
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "sibling_id,child_id,age,gender")] sibling sibling)
{
if (ModelState.IsValid)
{
db.siblings.Add(sibling);
db.SaveChanges();
return RedirectToAction("Index");
}
ViewBag.child_id = new SelectList(db.children, "child_id", "last_name", sibling.child_id);
return View(sibling);
}
This is my Create.cshtml for Sibling:
#model dummyApp.Schema.TestModels.sibling
#{
ViewBag.Title = "Create";
}
#section Scripts{
<script type="text/javascript">
//Coding
$("#numBox").change(function () {
var htmlString = "";
var len = $(this).val();
for (var i = 0; i < len; i++) {
htmlString += ' <div class="form-group">\
#Html.LabelFor(model => model.child_id, "child_id", htmlAttributes: new { #class = "control-label col-md-2" })\

Please help. Thank you!

You can use AddRange method in EF-6
IList<Student> newStudents = new List<Student>();
newStudents.Add(new Student() { StudentName = "Student1 by addrange" });
newStudents.Add(new Student() { StudentName = "Student2 by addrange" });
newStudents.Add(new Student() { StudentName = "Student3 by addrange" });
using (var context = new SchoolDBEntities())
{
context.Students.AddRange(newStudents);
context.SaveChanges();
}
