linq - EntityFramework 6 in ASP.NET MVC4 Data Annotations -


i want data between db.tableas , db.tablebs using following method:

class tablea.cs:

public class tablea {     [key]     public int id {get;set;}     public int tablebid {get;set;}     public string description{get;set;}     public virtual tableb tablebs{get;set;} }

class tableb.cs:

public class tableb{     [key]     public int id {get;set;}     public int tableaid {get;set;}     public string description{get;set;}     public virtual tablea tableas{get;set;} }

i have functions need tableb's data tablea , functions need tablea's data tableb. doing getting error:

unable determine principal end of association between types 'tablea' , 'tableb'. principal end of association must explicitly configured using either relationship fluent api or data annotations.

can know how data without codes below:

tableb tableb = _tablebmodel.getsingle(tablea.id);  public tableb getsingle(int id) {     return db.tablebs.where(e => e.id == id).firstordefault(); }

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
