How can you create a non-empty CharField in Django?

another option that doesn’t require you to manually call clean is to use this:

name = models.CharField(max_length=100, blank=False, default=None)

• blank will prevent an empty string to be provided in the admin or using a form or serializer (most cases). However as pointed out in the comments, this unfortunately does not prevent things like model.name = "" (manually setting blank string)
• default=None will set name to None when using something like group = Group(), thus raising an exception when calling save
