Django LowerCaseCharField

Question

We implemented a LowerCaseCharField. We would be happy to hear better implementation suggestions.

from django.db.models.fields import CharField

class LowerCaseC         


        

Answer 1

Another way to do it would be to add a pre_save hook to your model, and then just convert all the fields you want to be lowercase to lowercase there using lower(). This is discussed here in a slightly different fashion. This way, any time the object is saved its field is converted to lower case.

Example:

@receiver(pre_save, sender=YourModel)
def convert_to_lowercase(sender, instance, *args, **kwargs):
    instance.lowercase_field = instance.lowercase_field.lower()
