Strip ArrayField input from admin

[Erik Cederstrand]

Hi list

I have a model with a field defined like this:

categories = ArrayField(models.CharField(max_length=32))


This field is accessible via the admin interface, and when I enter comma-separated values in the charfield, they are stored as an array in the DB.

However, I just discovered that if I enter comma+space separated values, e.g. "teachers, locations, students", it gets converted to ['teachers', ' locations', ' students'] which is not what I want. How go I get the ArrayField to strip the values after splitting by comma?

Thanks,
Erik

Well, that was easy. Just subclass ArrayField:

class StrippedArrayField(ArrayField):
def pre_save(self, model_instance, add):
stripped_array = [s.strip() for s in getattr(model_instance, self.attname)]
setattr(model_instance, self.attname, stripped_array)
return stripped_array
