i have a problem when executing a method ,

def wtc_approval(self, cr, uid, ids,vals, context=None):
        user = self.pool.get("res.users").browse(cr, uid, uid)['groups_id']
        line = self.browse(cr, uid, ids, context=context)
    
        for x in user:
            if line.app_line.group_id == x :
                line.app_line.write({
                                       'sts':'2',
                                       'pelaksana':uid,
                                       'tanggal':datetime.today()
                                       })
            print "adaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",x
   
        return True

it said

ValueError

Expected singleton: wtc.approval.line(166, 167, 168, 169)

what should i do ?

If you use the list of Objects or List in the place of single value python will raise the error. Try use x.id instead of x. Also ensure that print line.app_line.group_id & print x.id should be single values(Not Links or Pointer).

Just an idea: def self.browse() ...

Hi, Ajeng


I have checked the above code and found you are passing "ids" parameter inside "wtc_approval" method and ids parameter may contain more than one ids that's why you are getting this issue. You can write your code like below,

def wtc_approval(self, cr, uid, ids,vals, context=None):
        user = self.pool.get("res.users").browse(cr, uid, uid)['groups_id']
        lines = self.browse(cr, uid, ids, context=context)
    
        for x in user:    
            for line in lines:
                if line.app_line.group_id == x :
                    line.app_line.write({
                                           'sts':'2',
                                           'pelaksana':uid,
                                           'tanggal':datetime.today()
                                           })
            print "adaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",x
        return True

Feel free to ask in case you still have the same issue.

Hola resolvi el problema para esto dirigete a mi pagina ahi explico como hacer algo similar.

@api.multi

def onchange_get_organizer_account(self,auxType):

if auxType:

ids=self.env['gol.organizer.account'].search([['organizerType', '=', auxType]])

auxIds=[]

for item in ids:

auxIds.append(item.id)

print ids

print auxIds

return {'domain':{'organizerAccount':[('id','in',auxIds)]}}

@api.onchange('organizerAccount','code')

def getCode(self):

if self.organizerAccount:

self.code=self.organizerAccount.code
