c# - Create map with DBContext lookup, using automapper and ninject -

so i'm trying use dbcontext information db mapping.

so create custom typeconverter:

public class roundvmtotrampetround : itypeconverter<roundvm, trampetround> {      public roundvmtotrampetround(dbtariff context)     {         this.context = context;     }      private dbtariff context { get; set; }      public trampetround convert(resolutioncontext context)     {         roundvm source = (roundvm)context.sourcevalue;         mapper.createmap<roundvm, trampetround>();         var dest = mapper.map<trampetround>(source);         dest.difficulty = this.context.difficultytrampet.find(source.id);         return dest;     } } 

and in controller create mapper using:

mapper.createmap<roundvm, trampetround>().convertusing<roundvmtotrampetround>(); 

but when mapping error message saying there no default constructor. want ninject me code:

kernel.bind<dbtariff>().toself().inrequestscope(); 

an answer here still same problem automapper + ef4 + asp.net mvc - getting 'context disposed' error (i know why, how fix it?)

i have tried solution given in link same error. how automapper use ninject fix problem?

edit

i found same thing done autofac http://thoai-nguyen.blogspot.se/2011/10/autofac-automapper-custom-converter-di.html guess need tell automapper use ninject resolver how , where?

all information need given in blog article linked. break down absolute minimum information, need do:

mapper.initialize(x => {      x.constructservicesusing(type => kernel.get(type)); }); 

before ever access other mapper. property / method, need call mapper.initialize(..) before mapper.createmap.
