How do I create a ListField in Django (Python) like the ListProperty property in Google App Engine (Python)? My data is a list like this : 3,4,5,6,7,8.
What property do I have to define and how would I fetch values from it?
I do this:
def get_comma_field(self, field):
data = getattr(self, field)
if data:
return data.split(',')
return []
def set_comma_field(self, val, field):
if isinstance(val, types.StringTypes):
setattr(self, field, val)
else:
setattr(self, field, ','.join(val))
def make_comma_field(field):
def getter(self):
return get_comma_field(self, field)
def setter(self, val):
return set_comma_field(self, val, field)
return property(getter, setter)
class MyModel(models.Model):
_myfield = models.CharField(max_length=31)
myfield = make_comma_field('_myfield')
But I suppose now it might be overkill. I needed quite a few of them, which is why I wrote the make_comma_field function.
