asp.net mvc 4 - Calling action method for different entity in controller web api -

i have mvc 4 application. migrating of logic use web api. cannot make changestate method work in following code ( 404 file not found). saw post:

webapi adding method

and thinking of making different controller states different entity, curious how make work situation.

public class franchisecontroller : apicontroller {     [datacontext]     public ienumerable<franchiseinfoviewmodel> getallfranchises()     {         var allfranchises = new list<franchiseinfoviewmodel>();         var franchiseinfolist = _franchiseservice.getall();          foreach (var franchiseinfo in franchiseinfolist)         {             allfranchises.add(new franchiseinfoviewmodel(franchiseinfo, p => p.isimportant));         }          return allfranchises;     }      [datacontext]     [system.web.http.httppost]     public string changestate(int franchiseid, franchiseproductionstates state)     {         _franchiseservice.changeproductionstate(franchiseid, state);          var redirecttourl = "list";          return redirecttourl;     }      [datacontext]     public franchiseinfoviewmodel getfranchise(int? franchiseid)     {         var realid = franchiseid ?? default(int);         var franchiseinfo = _franchiseservice.createorget(realid);          var franchiseinfoviewmodel = new franchiseinfoviewmodel(franchiseinfo, p => true);          return franchiseinfoviewmodel;     } } 

here routes:

config.routes.maphttproute(     name: "defaultapi",     routetemplate: "api/{controller}/{id}",     defaults: new { id = routeparameter.optional },     constraints: new { id = @"\d*" } );  config.routes.maphttproute(     name: "defaultapiplusactionandfolderid",     routetemplate: "api/{controller}/{action}/{franchiseid}/{state}",     defaults: null,     constraints: new { action = @"[a-za-z]+", franchiseid = @"\d+", state = @"[a-za-z]+" } ); 

and js code calling action method:

var changestate = function (franchiseid, state) {     var deferred = $.deferred();     amplify.request({         resourceid: 'changestate',         success: deferred.resolve,         error: deferred.reject,         data: { franchiseid: franchiseid, state: state }     });     return deferred; };  amplify.request.define('changestate', 'ajax', {     url: "/api/franchise/changestate",     type: "post",     datatype: 'json',     decoder: errorsdecoder }); 

note: franchiseproductionstates of type enum. suggestions welcome. first experience web api. thanks!

i able make work:

here how action method should like:

[httpput] public string changestate(int id, [frombody]franchiseproductionstates state) {     _franchiseservice.changeproductionstate(id, state);      var redirecttourl = "list";      return redirecttourl; } 

note added [frombody] attribute. in fact put verb, not post.

this route:

config.routes.maphttproute(                 name: "test",                 routetemplate: "api/{controller}/{action}/{id}",                 defaults: new { id = routeparameter.optional }             ); 

and how ajax call should done:

amplify.request.define('changestate', 'ajax', {                     url: "/api/franchise/changestate/3",                     type: "post",                     //datatype: 'json',                     contenttype: 'application/json; charset=utf-8',                     decoder: errorsdecoder                 }); 

for simplicity have hardcoded id parameter added url.

thanks!
