set_relation where 'field' = current primary key

Hi,

I am trying to set a relation but I want to filter the results from the relation table based on the value of the primary key in the source table. I thought I could use get_primary_key() in some way but have hit a dead end with it.

By way of illustration;

[size=3][font=courier new,courier,monospace]source_table
source_id, relation_field

relation_table
relation_id, relation_name[/font][/size]

I want something like this on source_table;

$this->grocery_crud->set_relation(

					'relation_field',

					'relation_table',

					'relation_name',

					array('relation_id' => source_id)

					);

Hope this makes sense! Thanks in advance.

Cheers,
Geoff
