asp.net mvc - Entity Framework Debacle -

I am developing an MVC application which I am not clear in the ideal way to save these institutions. What I am doing now is bad to say the least.

My action takes the method view modals and uses the automaker to map them to the respective organizations. My organizations are requesters, orders and orders dिपate.

Obviously all these calls are wrong with the exchange system, but instead of updating among other things, I am going on the issue of new children.

Any help how this code should look really appreciated.

 Firstly you can clear your questions a little bit.  
  var req = (Select r.RequestorID == requestor.RequestorID from DB requests. R) .SingleOrDefault (); Var or = (from db.Orders.Include ("OrderDetails") where O. RixsterID == Requestor. Select Configuration ID.) .SingleOrDefault ();   
 Take a look at this: works to map all your related data. it's very useful.  
 You only have to make a call to save once.
