Note: there is another thread on a similar problem, but this question is more detailed and the answer mentioned in the post above is not satisfactory (elaborated below)
I was trying to create a custom Django model field, where the new field will essentially be the same as a CharField but has an additional boolean attribute -- for now, just call it "public."
I have looked up this article, but I don't like the method described as it required me to construct a model from scratch. That solution is a hassle considering the number of functions I must implement to add a parameter, per the docs.
To clarify my objectives, I will like to declare this field as such:
somefield = BoolCharField(public=True, max_length=100, blank=True)
# Note that public is NOT a default CharField attribute
The documentation stated that I can extend new fields from existing ones, but the process isn't elaborated. Can anyone please provide me with an example of how I should implement my field?
This is the source code of CharField in case anybody needs a reference.
Update
I had a look at overriding the default __init__ method. Here's what the documentation suggests:
from django.db import models
class HandField(models.Field):
def __init__(self, *args, **kwargs):
kwargs['max_length'] = 104
super().__init__(*args, **kwargs)
However, the docs didn't specify how exactly overriding works in this case (e.g. where should I throw in an additional attribute and what methods I must include), which made me post this question.
Again, as I have been stuck for quite some time, I'd prefer examples instead of concepts.
