`Hello everyone, I'm running into a problem with my colleague's assignment and could really use some assistance. The issue pertains to ASP.NET Core MVC. I have an API Controller for editing student groups. This API Controller receives a GroupViewModel as a parameter for updating purposes. While the model received is valid, the variables within it are showing up as null. When examining the request being sent from the client-side, data is present. Your insights and help are greatly appreciated!
There are a couple of approaches you can take:
Approach 1: Consider removing JSON.stringify and contentType from your AJAX call:
$.ajax({
type: 'POST',
url: '/Enrollment/EditGroup',
data: updatedGroup,
success: function (r) {
console.log("RESULT", r);
},
error: function (xhr, status, error) {
var err = eval("(" + xhr.responseText + ")");
alert(err.Message);
}
});
This would yield the following outcome:

Approach 2: Another option is to include [FromBody] in your controller method signature like so:
[HttpPost]
public IActionResult EditGroup([FromBody]GroupViewModel _data)
{
//perform necessary actions here
}
This approach would result in:
