Modifying from MVC to WebAPI

I have to make a private personal site to work with Android  / IPhone /Windows Phone natively. So I have to open the data from the site.

But what is better then http://en.wikipedia.org/wiki/Eating_your_own_dog_food ? So I decide to do modifications for this

The site was a simple listing of steps to solve a dangerous situation –see the below image:

 

The code was realize with a ViewModel and some ajax call( cascading drop downs) .

The ViewModel was this

public class ChooseDangerSituation
    {
        public List<KVD> Danger;
        public List<KVD> Situation;
        public List<Tuple<int, int>> DangerSituation;

So I list here the steps:

1.  Returning the same ViewModel class from the WebAPI:

public class SurvivingController : ApiController
  {
      public ChooseDangerSituation DangerSituations()

 

2. Modifying view controls and loading from javascript:

In my example  instead of DropDownList :

var danger = Model.Danger.Select(item => new SelectListItem() { Text = item.Value, Value = item.Key.ToString() }).ToArray();

@Html.DropDownList("idDanger",danger, "Danger")

I had to modify into select :

<select id="idDanger" name="idDanger">
    <option value="">Danger</option>
</select>

3. Modify all JsonResult to HttpResponseMessage

This

return Json(new { ok = true, data = q });

will become this

return Request.CreateResponse(HttpStatusCode.OK, new { ok = true, data = q });               

 

 

Side note:
For a real application you should generate unobtrusive validation. Also, you may want to create Validationmessages. Also WebApi let’s you define routes more easily: [Route("GetSteps/{idDanger}/{idSituation}")]

 

 

That it will be all.
