[For reasons I mention
in
https://github.com/encode/django-rest-framework/issues/3144#issuecomment-431446248
I can't really just insert code into validate() in the ModelSerializer.]
My requirements are also not that complicated -- I only care about the
validators passed to the field in Django when it is made, i.e.,
foo = models.CharField(validators=[....])
I also don't care about any foo_validate methods in the model that does
further cleaning.
My desire is kind of rooted in that DRF doesn't seem to incorporate the
max_length validator in the model's fields when a max_length is specified.
I also want to check regexes, which I have specified in the model to also
create regex constraints.
So I've come up with two solutions ... I'm looking for feedback in case
there is something I'm not thinking about.
In say, FooSerializer,
foo =
serializers.CharField(validators=FooModel._meta.get_field('foo').validators)
and the case when 'foo' is just in Meta.fields...
def validate_foo(self, value):
if value is not None:
for v in FooModel._meta.get_field("foo").validators:
v(value)
return value
Is there a more elegant approach I should be using instead?
