EF: Partial class - acces to the adapter? - entity-framework

Question

let's say that I have a table TabA
namespace MyProject.Models.Database //<-- the same namespace as the EF's dbmx file
{
public partial class TabA
{
public void Foo()
{
//
}
}
}
Inside the Foo method, I need to perform some operations on the other table which isn't asosiated with the TabA In the other words, I need to access to the Entity Framework adapter inside that method. Is it possible ?

Answer 1

If I understand the problem correctly, I assume you have your reasons for wanting to work on another entity from the TabA entity. If this is true, I can see two ways of doing this.
A) If you want your changes to be applied at the same time as other potential changes to the TabA Entity, then you can always pass in the context as a parameter:
namespace MyProject.Models.Database //<-- the same namespace as the EF's dbmx file
{
public partial class TabA
{
public void Foo(YourDbContext context)
{
var otherTableQuery = from x in context.SecondTable
where ...
select x;
foreach (var item in otherTableQuery)
{
item.Column1 = "A certain value";
}
}
}
}
Your calling method might look like:
public void DoChangesToTabA()
{
using ( YourDbContext context = new YourDbContext())
{
var tabAquery = from x in context.TabA
where ...
select x;
foreach( var item in tabAQuery)
{
item.LastModified = DateTime.Now;
if(???)
{
}
}
}
}
Now your changes will be applied the next time you call context.SaveChanges() from the calling method.
