Controller for removing an entity not fetching the id
0
I have this controller method
[HttpGet]
public IActionResult DeleteMake(int id)
{
var data = _dbContext.VehicleMake.Find(id);
return View(data);
}
I generated a delete view for it. I assumed that based on the entity I clicked delete on, it would get it's information. It doesn't. I don't know why. The id in the parameter is always 0. Interesting enough, if you type in something like .../DeleteMake/1, then it works on the id of 1. Just doesn't work with the view.
This is the view
@model Data.Entities.VehicleMakeEntity
@{
ViewData["Title"] = "DeleteMake";
}
<h2>DeleteMake</h2>
<h3>Are you sure you want to delete this?</h3>
<div>
<h4>VehicleMakeEntity</h4>
<hr />
<dl class="dl-horizontal">
<dt>
@Html.DisplayNameFor(model => model.Id)
</dt>
<dd>
@Html.DisplayFor(model => model.Id)
</dd>
<dt>
@Html.DisplayNameFor(model => model.Name)
</dt>
<dd>
@Html.DisplayFor(model => model.Name)
</dd>
<dt>
@Html.DisplayNameFor(model => model.Abrv)
</dt>
<dd>
@Html.DisplayFor(model => model.Abrv)
</dd>
</dl>
<form asp-action="DeleteMake">
<input type="submit" value="Delete" class="btn btn-default" /> |
<a asp-action="Index">Back to List</a>
</form>
And the method I use to actually list all the items
private readonly IQueryable<VehicleMakeEntity> _source;
public MakeRepository(ProjectDbContext context)
{
this.context = context;
_source = this.context.VehicleMake;
}
public IEnumerable<VehicleMakeEntity> SelectListMake(int index, int count, Expression<Func<VehicleMakeEntity, int>> orderLambda)
{
return _source.Skip(index * count).Take(count).OrderBy(orderLambda);
}

Your form does not post back anything. Either add a route value for the ID in the<form>or add a hidden input for the ID

I don't see in the code where the view is passing the ID to delete....

How would I do that @StephenMuecke?

Nov 20 '18 at 9:25
Your could addasp-route-id="@Model.Id"in the<form>element, or add a hidden input -<input type="hidden" asp-for="Id" />or@Html.HiddenFor(m => m.Id)

I just tried it. The third one doesn't error out but the issue is still the same. ` <form asp-action="DeleteMake"> <input type="submit" value="Delete" asp-route-id="@Html.HiddenFor(m => m.Id)" class="btn btn-default" /> | <a asp-action="Index">Back to List </a> </form>`

Your could addasp-route-id="@Model.Id"in the<form>element, or add a hidden input -<input type="hidden" asp-for="Id" />or@Html.HiddenFor(m => m.Id)

I just tried it. The third one doesn't error out but the issue is still the same. ` <form asp-action="DeleteMake"> <input type="submit" value="Delete" asp-route-id="@Html.HiddenFor(m => m.Id)" class="btn btn-default" /> | <a asp-action="Index">Back to List </a> </form>`
