initial	v1
	1	Replying to [comment:4 Sarah Boyce]:
	2	> To me, the issue here is in the string method should always return a string (eg. `return self.author or ""`)
	3	> If you want to keep spaces, you will need a custom form with `strip=False` (see https://docs.djangoproject.com/en/5.1/ref/forms/fields/#charfield)

1	5	sarahboyce, I have a small question. 🙋
2	6	It seems this issue occurs because even though we set `blank=True` in the `Field(Model)`, but the admin `Form` doesn't allow empty value.
