Thanks Anthony, I will go with the first option and guess how to adapt
it to postgress too.
Greetings.

Hi guys, I have a list of ids, and I need to obtain the records
keeping
the list order. In MySQL I can use FIELD() in the "order by" for
that.
Can I get the ordered records using the DAL?
The DAL doesn't have anything built in that will work across database
backends, but if you are using MySQL, you should be able to do:
|
db(query).select(orderby='Field(id, %s)'%', '.join(str(id)forid
inlist_of_ids))
|
Alternatively, if the list is not too long, you can just do the
sorting in Python after selection:
|
db(query).select().sort(lambdar:list_of_ids.index(r.id))
