I have an ASP.NET Core API that takes in a DTO parameter called DetParameterCreateDto
which looks like this
DTO
public class DetParameterCreateDto
{
public int Project_Id { get; set; }
public string Username { get; set; }
public string Instrument { get; set; }
public short Instrument_Complete { get; set; }
}
The problem I am having is that the parameter passed in from the client has a property named Instrument_Complete
; which is dynamic.
The name is actually [instrument]_complete
where [instrument]
is the name of the instrument. So if the name of the instrument is my_first_project
then the parameter's property name will actually be my_first_instrument_complete
, which will not properly map to my API's input parameter; so it always shows a value of 0
API Method
[HttpPost("create")]
public IActionResult CreateDetEntry(DetParameterCreateDto detParameters)
{
// some stuff in here
}
Update (8/2)
Using bradley's suggestion it seems like I can do this with custom model binding. However, I have to set each model property instead of just the one I want to set instrument_complete
(and convert some from string). This does not seem like an optimal solution.
public Task BindModelAsync(ModelBindingContext bindingContext)
{
if (bindingContext == null)
{
throw new ArgumentNullException(nameof(bindingContext));
}
var instrumentValue = bindingContext.ValueProvider.GetValue("instrument").FirstValue;
var model = new DetParameterCreateDto()
{
Project_Id = Convert.ToInt32(bindingContext.ValueProvider.GetValue("project_id").FirstValue),
Username = bindingContext.ValueProvider.GetValue("username").FirstValue,
Instrument = instrumentValue,
Instrument_Complete = Convert.ToInt16(bindingContext.ValueProvider.GetValue($"{instrumentValue}_complete").FirstValue),
bindingContext.Result = ModelBindingResult.Success(model);
return Task.CompletedTask;
}
DTO params
in Web API are limiting especially when the properties are dynamic. I solved a similar issue before by using JObject
. Yours could be something like:
[HttpPost("create")]
public IActionResult CreateDetEntry(JObject detParameters)
{
//DO something with detParameters
...
//Optionally convert it to your DTO
var data = detParameters.ToObject<DetParameterCreateDto>();
// or use it as is
}
