Doubt in onchange function, wants to return date.

rosey

I have four fields

join - date field

rejoin - date field

date - date field

days - char

When we enter join/rejoin date field, it will call the onchange function.

def on_change_join/rejoin(self, cr, uid, ids, join/rejoin, context=None):
          records = self.browse(cr, uid, ids, context=context)
          res = {}
          for r in records:

              vacation_due = 0
              format_string = "%Y-%m-%d"
              if r.join/rejoin:
                  datetime_object = datetime.strptime(r.join/rejoin, format_string).date()
                  print "datetime_object",datetime_object
                  new_date = datetime_object + relativedelta(years=2)
                  print "new_date",new_date
                  new_date_string = datetime.strftime(new_date,format_string)
                  print "new_date_string",new_date_string


              return {'value': {'date': new_date_string}}

But it doesnt shows clear output. ie, it shows error when i first enter join/rejoin date

Error: return {'value': {'date': new_date_string}}

UnboundLocalError: local variable 'new_date_string' referenced before assignment

When i enter days, it will sum up with date field. But it also shows error

def my_onchange_days(self, cr, uid, ids,days, context=None):

return {'value': {'date': (datetime.strptime(date,'%Y-%m-%d %H:%M:%S') + relativedelta(days=days)).strftime('%Y-%m-%d %H:%M:%S')}}

Please help me any one to solve this.

Hi rosey, i either of both tho functions you need to check the field value befor doing and calculation on it

def on_change_join/rejoin(self, cr, uid, ids, join/rejoin, context=None):
records = self.browse(cr, uid, ids, context=context)
res = {}

        new_date_string = False
          for r in records:
              vacation_due = 0
              format_string = "%Y-%m-%d"
              if r.join/rejoin:
                  datetime_object = datetime.strptime(r.join/rejoin, format_string).date()
                  print "datetime_object",datetime_object
                  new_date = datetime_object + relativedelta(years=2)
                  print "new_date",new_date
                  new_date_string = datetime.strftime(new_date,format_string)
                  print "new_date_string",new_date_string

return {'value': {'date': new_date_string}}

And

def my_onchange_days(self, cr, uid, ids,days, context=None):
   res = {}
   if days:
       res['date'] : (datetime.strptime(date,'%Y-%m-%d %H:%M:%S') + relativedelta(days=days)).strftime('%Y-%m-%d %H:%M:%S')}
return {'value': res }

Dimple

hai, i getting this error while doing this code res['date'] : (datetime.strptime(date,'%Y-%m-%d %H:%M:%S') + ^ relativedelta(days=days)).strftime('%Y-%m-%d %H:%M:%S')} SyntaxError: invalid syntax

Ivan

Did you notice the ^ sign in front of relativedelta that you have pasted?

hi,

for resolve "UnboundLocalError: local variable 'new_date_string' referenced before assignment", try:

def on_change_join/rejoin(self, cr, uid, ids, join/rejoin, context=None):
records = self.browse(cr, uid, ids, context=context)
res = {}
vals = {}
for r in records:

vacation_due = 0
format_string = "%Y-%m-%d"
if r.join/rejoin:
datetime_object = datetime.strptime(r.join/rejoin, format_string).date()
print "datetime_object",datetime_object
new_date = datetime_object + relativedelta(years=2)
print "new_date",new_date
new_date_string = datetime.strftime(new_date,format_string)
vals['date'] = new_date_string
print "new_date_string",new_date_string


return {'value': vals}

reagards,

Dimple

hai, i tried this code but it didn't returning any value. what will i do to return the value?

Temur

-in this line, why you're passing 'date_rejoin' as parameter in XML? you've another field named "date_rejoin"? if you're trying to pass this same field, then please try instead. I mean that you've to use parameter name exactly as it appears in 'name' paroperty (name="rejoin"...). Same for other fields.

Temur

in this line: field name="rejoin" on_change="on_change_rejoin(date_rejoin) try instead: field name="rejoin" on_change="on_change_rejoin(rejoin) -these parts disappeared from my previous comment, due to xml tags... < >
