I just researched my "bug" and it turned out to be a new feature in Django 1.9 that CharFields strip spaces by default : https://docs.djangoproject.com/en/1.9/ref/forms/fields/#django.forms.CharField.strip
The same seams to apply to text fields TextField.
So I found out why Django suddenly behaves differently than before, but is there an easy way to restore the previous default for auto generated admin forms?
I would like to NOT strip spaces while still using the auto generated form from the admin. Is that still possible?
If you are looking for a text/char field and do not want it to strip white spaces you can set strip=False in the constructor method of a form and then use the form in the admin
class YourForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(YourForm, self).__init__(*args, **kwargs)
self.fields['myfield'].strip = False
class Meta:
model = YourModel
fields = "__all__"
You can then use this form in the admin by specifying form=YourForm
in the admin.py file.
