if you already have that, and no realy need, replace it by a read

employee_data = employee_obj.browse( cr, uid, ids, context=context)


for employee in employee_obj.read( cr, uid, ids, ['contract_ids'], context=context):
    #So in employee['contract_ids'], you have a list of all contract id for this employee

option a is right way as option b dose not make any sense. we can say it is mistake of coding in IMO.

--> there is one big plus point of option a: As it will avoids search on object so it will good if you have lots of records in db.

option 1 , is a no sense, browse will read ALL field in db, so performance drop, trace the code, if you have 80 fields in the table, openerp will create a select query for 80 fields. Always avoid Browse, browse is for lazy programmer.

what if you have 10-20 lakh records and you fire search query then it will take less time than browse of 80 fields????? in this case search makes no sense.

No need a search if you already have the IDS, if you do a browse, mean you have IDS, so do a READ not a BROWSE.
