Hi,

I have a web-api application that has a posts to a database table in my localDB. I want to make the client (right now using postman) to select which table it will be posting to using a query string. I know that post method only accepts one post parameter so I want to pass just one but with multiple selective models in it. (not sure if I explained that right)

Basically I just want to combine JT JT and sales sales into one parameter and use it in my entity add() method. But I don't have an idea how.

Here's my sample code.

[HttpPost]
        public HttpResponseMessage PostJT(JT JT, Sales Sales, [FromUri] string tran)
//I want to combine JT JT, and sales sales
        {

            //JT JT = new JT();
            //Sales Sales = new Sales();

            try
            {
                if (ModelState.IsValid)
                {
                                switch (tran)
                                {
                                    case "JT":
                                        db.JTs.Add(JT);
                                        db.SaveChanges();
                                        break;
                                    case "sales":
                                        db.Sales_.Add(Sales);
                                        db.SaveChanges();
                                        break;
                                }
                            }
                            return Request.CreateErrorResponse(HttpStatusCode.OK, "Added!");
                        }
                    }
                    else
                    {
                        return Request.CreateResponse(HttpStatusCode.Unauthorized, "Unauthorized Access!");
                    }
                }
                
            }
            catch (Exception ex)
            {
                return Request.CreateResponse(HttpStatusCode.InternalServerError, ex.Message);
            }

        }

Hopefully, someone helps me. I'm still getting the hang of web-api.
