QuestionWeird issue with input form on a simple ASP.NET core web application Pin
Maximilien22-Mar-23 6:49

I have a weird, or probably a simple dumb user error on a simple web application.

The project is created with the wizard. (asp.net core web app with a new controller with EF).

The database has been created and is working.

I have a model (1 string, 2 double values):
public class Person
 {
     [Key]
     public int Id { get; set; }
     public string Name { get; set; }
     public double Poids { get; set; }
     public double Glycemie { get; set; }
 }

In the generated Create Page.
<div class="row">
    <div class="col-md-4">
        <form asp-action="Create">
            <div asp-validation-summary="ModelOnly" class="text-danger"></div>
            <div class="form-group">
                <label asp-for="Name" class="control-label"></label>
                <input asp-for="Name" class="form-control" />
                <span asp-validation-for="Name" class="text-danger"></span>
            </div>
            <div class="form-group">
                <label asp-for="Poids" class="control-label"></label>
                <input asp-for="Poids" class="form-control" />
                <span asp-validation-for="Poids" class="text-danger"></span>
            </div>
            <div class="form-group">
                <label asp-for="Glycemie" class="control-label"></label>
                <input asp-for="Glycemie" class="form-control" />
                <span asp-validation-for="Glycemie" class="text-danger"></span>
            </div>
            <div class="form-group">
                <input type="submit" value="Create" class="btn btn-primary" />
            </div>
        </form>
    </div>
</div>

Addition :
in the Create method, the value for the Glycemie is zero, as if it was not entered in the form.
As if the binding did not work ???
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Create([Bind("Id,Name,Poids,Glycemie")] Person person)
{
    if (ModelState.IsValid)
    {
        _context.Add(person);
        await _context.SaveChangesAsync();
        return RedirectToAction(nameof(Index));
    }
    return View(person);
}

When I type in the data, name "Max" , poids (weight) "123" and glycemia 4.5 value, I get an error on the glycemia value saying the value is not valid.

See image :

When i just type 4 (instead of 4.5) it works.

I'm not sure where or what validation is done.

Anything stupid or obvious I missed ?

THanks.
