I am new to OpenERP development and I am trying to learn how to assign functions to fields so I can retrieve values based on my needs, but after following the manual or taking a look at the code from another modules I can't seem to get it right.
I tried a really simple function to retrieve the current time into a field. Here is the code to my function
def get_text(self, cr, uid, ids, fields, arg, context): #records = self.browse(cr, uid, ids) #sale = 'Some Text' dd = datetime.now() return dd
And this is how I call the
'varText': fields.function(get_text, obj='sim.student', method=True, store=False, type='string', string='Text')
Whatever I try in my
get_text function I always get an error like the following:
AttributeError: 'datetime.datetime' object has no attribute 'get'
If I comment the line starting with
dd and uncomment the line starting with
sale the error would be
AttributeError: 'str' object has no attribute 'get'
If anyone can give me a tip on what I am doing wrong I will really appreciate it!
- In you field singature the
objis not requied as it is not a relation type field.
type='string'will not work. You should use
- but as you try to get a datetime fields the correct type should be
- The return of
get_textshould be a dict with keys the ids of the record and values the related values
You should have a look at the
hr_attendance/hr_attendance.py of addons file
'last_sign': fields.function(_last_sign, type='datetime', string='Last Sign') is a simple sample
