Hi guys,

I need to map the following senario and could do with some help.

I have a Content entity, that has a unique id to identify itself, however each Content entity has a shared id property. The perpose of this property is to group the content items together.

What i want to do though is have that shared id as an autoinrementing number (ie for an item that is created with no shared id a new id is created one increment higher than the maximum shared id value in the database) but is unique per group, not per row like the primary key.

Hopefull i've explained this well enough.

Could anybody offer any advice on how to go about this?

Many thanks

Matt

How do you identify group for content entities?

It's just a integer, ie

Id.....Group
1.......1
2.......1
3.......1
4.......2
5.......2
6.......2
7.......2
8.......3

etc

I mean how do you decide that 1,2,3 have group id 1 and 4,5,6,7 belongs to group 2.

Ahh, if an item belongs to a group this will be set manually by seleting on the front end what group it belongs to. If when saved it does not belong to a group, it should create and belong to the next group number.
