How to disable a route (or allow duplicates) from the parent controller class

Question

I want a child controller to have query parameters while the default implementation in the base controller has none. I have a base controller that all other controllers inherit from. The controller has a Get() method:

public abstract class BaseEntityController : Controller
{
  [HttpGet]
  [Route("")]
  public virtual Task<IActionResult> Get()
  {
      DoSomeGetAllFunctionallity();
  }
}

In one of the child controllers I want to have some query parameters in the for the get all method:

public abstract class ChildController : BaseEntityController
{
  [HttpGet]
  [Route("")]
  public async Task<IActionResult> Get([FromQuery(Name = "param-1")] int? param1, [FromQuery(Name = "param-2")] bool param2 = false)
  {
    DoSomeGetAllFunctionallity(param1, param2);
  }
}

When trying to test this with Swagger I get the error:

Swashbuckle.AspNetCore.SwaggerGen.SwaggerGeneratorException: 'Conflicting method/path combination "GET endpoint" for actions - path-to-controller.Get, path-to-controller.Get. Actions require a unique method/path combination for Swagger/OpenAPI 3.0. Use ConflictingActionsResolver as a workaround'

I would be happy with the following two outcomes:

1. Override the route of the base class to disable it

[Route(disable: true)]
public override Task<IActionResult> Get() => throw new NotImplementedException();

2. Pass the default parameters through to the other method

public override Task<IActionResult> Get() => Get(null, false);

I have not found a solution for either of the two outcomes.

Answer 1

I found an answer that works for me. An action method can be disabled by adding the [NonAction] attribute. This way the child controller can disable the parent action method and make its own for the same route.

public abstract class ChildController : BaseEntityController
{
  [NonAction]
  public override Task<IActionResult> Get() => throw new NotImplementedException();

  [HttpGet]
  [Route("")]
  public async Task<IActionResult> Get([FromQuery(Name = "param-1")] int? param1, [FromQuery(Name = "param-2")] bool param2 = false)
  {
    DoSomeGetAllFunctionallity(param1, param2);
  }
}
