Dears,

I paginate records using a medium complex query with :conditions :

like  id in (select ....) and id in (select ..)

Because that query is very high cost in time and ressources I'aint to
add
additionnals queries for counting or else.

Once one record is displayed, how access the next id in the paginated
collection, w/o querying again just for next id  ?

Like :

id   name
45  bob
47  bill
98  rob
78  david

In displaying rob's record (/show/98) i'll like to have Next and
Previous
record.

Thanks ,

In your paginate query pull down 1 more record than you display
just so you know its "Next" ID.
