controllers

i have base class api controlers:

public class baseapicontroller<t> : entitysetcontroller<t, int>     t: class, ientity, new() {     public irepository repositorio { get; private set; }     public baseapicontroller(irepository repositorio)     {         repositorio = repositorio;     }      [queryable(allowedqueryoptions = allowedqueryoptions.all, pagesize=20)]     public override iqueryable<t> get()     {         return repositorio.query<t>();     }      [queryable(allowedqueryoptions = allowedqueryoptions.all)]     protected override t getentitybykey(int key)     {         return repositorio.get<t>(key);     } }

and user controller

[authorize] public class usuarioscontroller : baseapicontroller<usuario> {     public usuarioscontroller(irepository repositorio)         : base(repositorio)     { }      [authorize(roles="admin,ti")]     public httpresponsemessage post(usuario usuario)     {         var x = websecurity.createuserandaccount(usuario.email, "maisbb", new { nome = usuario.nome }); //todo: não fixar senha         repositorio.store(usuario);          return request.createresponse(httpstatuscode.ok, usuario);     }      [httpget, queryable(allowedqueryoptions = allowedqueryoptions.all)]     public iqueryable roles([fromodatauri] int key)      {         var usuario = (from u in repositorio.query<usuario>()                     u.id == key                     select new { u.email }).singleordefault();         return roles.getrolesforuser(usuario.email).asqueryable();     } }

goals

an action roles retrieve roles specific user:
goal retrieve roles of user url:
/api/usuarios(67)/roles

i configured api webapiconfig follows:

modelbuilder.entityset<usuario>("usuarios"); var entitytypeusuario = modelbuilder.entity<usuario>(); var actroles = entitytypeusuario.action("roles"); actroles.parameter<int>("key"); actroles.returns<string[]>();  ...  var model = modelbuilder.getedmmodel(); config.routes.mapodataroute(routename: "odata", routeprefix: "api", model: model); config.enablequerysupport(); var jsonformatter = globalconfiguration.configuration.formatters.jsonformatter; var enumconverter = new stringenumconverter(); jsonformatter.serializersettings.converters.add(enumconverter); config.formatters.remove(config.formatters.xmlformatter); var jqueryformatter = config.formatters.firstordefault(x => x.gettype() == typeof(jquerymvcformurlencodedformatter)); config.formatters.remove(config.formatters.xmlformatter); config.formatters.remove(config.formatters.formurlencodedformatter); config.formatters.remove(jqueryformatter); config.formatters.jsonformatter.serializersettings.dateformathandling = dateformathandling.isodateformat;

error

get: /api/usuarios(67)/role

"this service doesn't support odata requests in form '~/entityset/key/action'."

erro webapi odata action

odataactions should post requests. can try modifying code following , see if resolves issue?

[httppost, queryable(allowedqueryoptions = allowedqueryoptions.all)] public iqueryable roles([fromodatauri] int key, odataactionparameters parameters)  {     var usuario = (from u in repositorio.query<usuario>()                 u.id == key                 select new { u.email }).singleordefault();     return roles.getrolesforuser(usuario.email).asqueryable(); }

also, need not specify parameter 'key' while building model key retrieved uri itself. updated code below:

modelbuilder.entityset<usuario>("usuarios"); var entitytypeusuario = modelbuilder.entity<usuario>(); var actroles = entitytypeusuario.action("roles"); actroles.returns<string[]>();

fyi: can @ nice post mike odata actions: http://www.asp.net/web-api/overview/odata-support-in-aspnet-web-api/odata-actions
