my code :

def search(self, cr, uid, args, offset=0, limit=none, order=none, context=none, count=false):     ''' overriden search method'''     cur_obj=self.pool.get('hr.job')     cr.execute('select job_code hr_job ')     list = cr.fetchall()     ids =  [ i[0] in list]     cr.execute('select id hr_applicant job_code_applicant in %s', (tuple(set(ids)),))     list12 = cr.fetchall()     ids_applicant =  [ i[0] in list12 ]     return ids_applicant 

error is:

keyerror: 8

in code why not return super of search method instead of returning direclty ids?

like:

def search(self, cr, uid, args, offset=0, limit=none, order=none,                        context=none, count=false):     #''' overriden search method'''     cur_obj=self.pool.get('hr.job')     cr.execute('select job_code '\                  'from hr_job '\               )     list = cr.fetchall()     ids =  [ i[0] in list]     if ids:         args.append(('job_code_applicant', 'in', ids))      return super(hr_applicant, self).search(cr, uid, args, offset, limit, order, context, count)
