I'm new to C# and I'm coding a web site in witch I need to insert multiple data in a row inside my database. some of the data will be set automatically and the others from form. here is my controller part:
public ActionResult chekout()
{
return View(new Commande());
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult chekout([Bind(Include = "Id_commande,prenom,nom,Adresse,telephone,Email,produit,prix,cart")] Commande commande)
{
var panier = from Panier in db.Paniers
select Panier;
var userEmail = this.User.Identity.Name;
panier = panier.Where(x => x.user.Contains(userEmail));
Panier[] pa = panier.ToArray();
List<Commande> list = new List<Commande>();
for (int i = 0; i < pa.Length; i++)
{
commande.Id_commande = db.Commandes.Max(I => I.Id_commande) + 1;
commande.produit = pa[i].Quantite + " X " + pa[i].nom_produit;
commande.prix = int.Parse(pa[i].prix) * pa[i].Quantite;
commande.Email = userEmail;
list.Add(commande);
}
db.Commandes.AddRange(list);
db.SaveChanges();
return RedirectToAction("order_complete", "Home");
}
and this is my view part:
#using(Html.BeginForm())
{
#Html.AntiForgeryToken()
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.prenom, htmlAttributes: new { #class = "control-label col-md-2" })

#Html.ValidationMessageFor(model => model.prenom, "", new { #class = "text-danger" })

<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type = "submit" value="Commander" class="btn btn-primary" />
</div>
</div>
}
I do not get error but I don't know why but it just adds the last row
so if anyone can help me I would be grateful.
You are adding the same commande object repeatedly in the loop, you need to instantiate new object commande in every iteration. You need to add the first line in loop below, please do change the variable name "commande" if a same name exist at class level.
for (int i = 0; i < pa.Length; i++)
{
Commande commande = new Commande ();
commande.Id_commande = db.Commandes.Max(I => I.Id_commande) + 1;
commande.produit = pa[i].Quantite + " X " + pa[i].nom_produit;
commande.prix = int.Parse(pa[i].prix) * pa[i].Quantite;
commande.Email = userEmail;
list.Add(commande);
}

Stripe capture the payment, on clicking the pay button on stripe payment, i will get the following error on postback.
The parameters dictionary contains a null entry for parameter 'amount' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Purchase(System.String, System.String, Int32, AllPlus.Models.Customer)' in 'AllPlus.Controllers.CheckoutController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
I know that the question was asked and answered many times, but unfortunately no one of the answers helped me.
I have tree POCO models, which are Pharmacy, Address and Company gathered together into a ViewModel PharmacyVM:
public class PharmacyVM
{
public Pharmacy pharmacyProp { get; set; }
public Address addressProp { get; set; }
public Company companyProp { get; set; }
public int CityId { get; set; }
public PharmacyVM()
{
pharmacyProp = new Pharmacy();
addressProp = new Address();
companyProp = new Company();
}
}
Don't laugh at the properties names; at the start, they had been normal (Address, Company and Pharmacy) I changed them according to one of the lots of answers in here, but... it didn't help :(
In the Get action of the Create method I'm trying to manually create the PharmacyVM object and pass it to the view:
public ActionResult Create()
{
ViewBag.CityId = new SelectList(db.Cities, "Id", "Name");
ViewBag.CompanyId = new SelectList(db.Companies, "Id", "Name");
ViewBag.AddressId = new SelectList(db.Addresses, "Id", "Name");
ViewBag.CityId = new SelectList(db.Cities, "Id", "Name");
ViewBag.RegionId = new SelectList(db.Regions, "Id", "Name");
ViewBag.DistrictId = new SelectList(db.Districts, "Id", "Name");
ViewBag.MicrodistrictId = new SelectList(db.Microdistricts, "Id", "Name");
ViewBag.StreetId = new SelectList(db.Streets, "Id", "Name");
ViewBag.VillageId = new SelectList(db.Villages, "Id", "Name");
var pharmacyVM = new PharmacyVM();
return View(pharmacyVM);
}
There is a standard Razor code in the view:
#model MEDONET.Models.PharmacyVM

ViewBag.Title = "Create";
}

And then in the Post action of the Create method, I'm trying to create b and c variables:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(PharmacyVM model, HttpPostedFileBase LargeImageFile)
{
if (ModelState.IsValid)
{
string LargeImageFileName = Path.GetFileNameWithoutExtension(LargeImageFile.FileName);
string LargeImageExtansion = Path.GetExtension(LargeImageFile.FileName);
LargeImageFileName = LargeImageFileName + DateTime.Now.ToString("yymmssfff") + LargeImageExtansion;
LargeImageFileName = Path.Combine(Server.MapPath("~/Images/Pharmacy/Banners/"), LargeImageFileName);
int b = model.CityId;
int c = model.addressProp.RegionId.Value;
//Address address = new Address()
//{
// Id = 12,//db.Addresses.AsEnumerable().Last().Id + 1,
// RegionId = PharmacyVM.Address.RegionId,
// DistrictId = PharmacyVM.Address.DistrictId,
// CityId = PharmacyVM.Address.CityId,
// MicrodistrictId = PharmacyVM.Address.MicrodistrictId,
// StreetId = PharmacyVM.Address.StreetId,
// VillageId = PharmacyVM.Address.VillageId,
// Building = PharmacyVM.Address.Building,
// Cab = PharmacyVM.Address.Cab
//};
//Address address = new Address
//{
// Id = 12,//db.Addresses.AsEnumerable().Last().Id + 1,
// RegionId = 1,
// DistrictId = 1,
// CityId = 1,
// MicrodistrictId = 1,
// StreetId = 1,
// VillageId = 1,
// Building = "1",
// Cab = "1"
//};
//db.Addresses.Add(address);
db.SaveChanges();
var pharmacy = new Pharmacy
{
Name = model.pharmacyProp.Name,
//AddressId = address.Id,
IsGov = model.pharmacyProp.IsGov,
CompanyId = model.pharmacyProp.CompanyId,
LargeImage = "~/Images/Pharmacy/Banners/" + LargeImageFileName
};
LargeImageFile.SaveAs(LargeImageFileName);
db.Pharmacies.Add(pharmacy);
db.SaveChanges();
ModelState.Clear();
return RedirectToAction("Index");
}
}
Unlike first variable b, the second one c is gonna be null because the addressProp property is null.
So why is it so strange? How can I use ViewModel without duplicating original model's fields?
why are you use
int b= model.addressProp.RegionId.Value
instead of
int b=model.addressProp.RegionId
Even for your good cording the best and good way is remove all View bag and
Add all View bag properties to PharmacyVM Class
Dont use two properties for view binding
Example
public class PharmacyVM
{
public Pharmacy pharmacyProp { get; set; }
public Address addressProp { get; set; }
public Company companyProp { get; set; }
public int CityId { get; set; }
public SelectList CityIdList { get; set; }
public PharmacyVM()
{
pharmacyProp = new Pharmacy();
addressProp = new Address();
companyProp = new Company();
CityIdList =new SelectList(db.Cities, "Id", "Name");
}
}
public ActionResult Create()
{
var pharmacyVM = new PharmacyVM();
return View(pharmacyVM);
}
#model PharmacyVM
#using (Html.BeginForm())
{
#Html.HiddenFor(m => m.CityId )
<div class="editor-label">
#Html.LabelFor(m => m.Name)
</div>
<div class="editor-field">
#Html.EditorFor(m => m.Name)
#Html.ValidationMessageFor(m => m.Name)
</div>
<button type="submit">Create</button>
}
[HttpPost]
public ActionResult Create(PharmacyVM model)
{
int c = model.addressProp
return View(viewModel);
}
More Information
I am naive to Asp.Net MVC.
I have a partial view(ASP.Net MVC) in which I have some required fields I want to show custom error message if any of the required field in not provided. Below is the complete cshtml code for my partial view.
#model CMSAdminPanel.ViewModel.ProductView
<h4>Material And Labour Cost For Each Size</h4>
<hr />
#Html.ValidationSummary(false, "", new { #class = "text-danger" })
#for (int i = 0; i < Model.ServiceView.ListPriceView.Count; i++)
{
#Html.HiddenFor(x => x.ServiceView.ListPriceView[i].ProductSizeType)
<div class="form-group">
#Html.LabelFor(x => x.ServiceView.ListPriceView[i].ProductSizeTypeName, "Size - " + Model.ServiceView.ListPriceView[i].ProductSizeTypeName, htmlAttributes: new { #class = "control-label col-md-4" })
</div>
<div class="form-group">
#Html.LabelFor(x => x.ServiceView.ListPriceView[i].LabourCost, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(x => x.ServiceView.ListPriceView[i].LabourCost, new { htmlAttributes = new { #class = "form-control", required = "required"} })
#Html.ValidationMessageFor(x => x.ServiceView.ListPriceView[i].LabourCost,"", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(x => x.ServiceView.ListPriceView[i].MaterialCost, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(x => x.ServiceView.ListPriceView[i].MaterialCost, new { htmlAttributes = new { #class = "form-control", required = "required" } })
#Html.ValidationMessageFor(x => x.ServiceView.ListPriceView[i].MaterialCost, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(x => x.ServiceView.ListPriceView[i].Profit, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(x => x.ServiceView.ListPriceView[i].Profit, new { htmlAttributes = new { #class = "form-control", required = "required" } })
#Html.ValidationMessageFor(x => x.ServiceView.ListPriceView[i].Profit, "", new { #class = "text-danger"})
</div>
</div>
}
I want to show custom message "Material cost is required" while I am getting "This field is required". So I want to override this difault error message on client side.
I want to achieve something like this:
<div class="form-group">
#Html.LabelFor(x => x.ServiceView.ListPriceView[i].LabourCost, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(x => x.ServiceView.ListPriceView[i].LabourCost, new { htmlAttributes = new { #class = "form-control", required = "required", **data_val_required = "LabourCost is requried"**} })
#Html.ValidationMessageFor(x => x.ServiceView.ListPriceView[i].LabourCost,"", new { #class = "text-danger" })
</div>
</div>
Any suggestion/solution would be great help
In your model class, add change the [Required] attribute to
[Required(ErrorMessage = "Material cost is required")]
public decimal MaterialCost {get;set;}
Another approach is to set it from JavaScript using JQuery or override the attribute that sets it. by default the output of the ValidationMessageFor is
data-val-required="The field is required.".
SO, you can override this value in your markup
I find out a way to override this default required message on Client Side by using htmlAttribute title property and below is the code :
<div class="form-group">
#Html.LabelFor(x => x.ServiceView.ListPriceView[i].LabourCost, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(x => x.ServiceView.ListPriceView[i].LabourCost, new { htmlAttributes = new { #class = "form-control", required = "required", title = "LabourCost is requried"} })
#Html.ValidationMessageFor(x => x.ServiceView.ListPriceView[i].LabourCost,"", new { #class = "text-danger" })
</div>
</div>
in your model
[Required(ErrorMessage = "Material cost is required")]
public doubleMaterialCost { get; set; }
and you can choose to load it from Resources and pass resource string if you have multiple cultures in your site.
or in your Action
public ActionResult(YourModel model)
{
if (model.doubleMaterialCost == 0)
ModelState.AddModelError("doubleMaterialCost ", "Material cost is required");
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">\

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();
}
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; }
}

Controller:
public ActionResult Info()
{
var flexModel = new FlexModel();
var userId = (int)Session["userId"];
var user = _db.Users.Find(userId);
var stampIn = _db.Stampings.Where(i => i.StampingType == "in").Where(i => i.User == user).ToList();
var stampOut = _db.Stampings.Where(i => i.StampingType == "out").Where(i => i.User == user).ToList();
var workDay = 8;
if (stampIn.Count == 0)
{
return View();
}
foreach (var itemIn in stampIn)
{
}
foreach (var itemOut in stampOut)
{
}
return View();
}
[HttpPost]
public ActionResult Info(FlexModel model)
{
if (ModelState.IsValid)
{
foreach (var item in model.Users)
{
_db.Entry(item).State = EntityState.Modified;
}
_db.SaveChanges();
return RedirectToAction("Index");
}
return View(model);
}
So this is not working for me, I get the value of Flex to display 0.
Help would be appreciated!
