compatible with django_model_utils Choices

[dbinetti]

I am using @carljm's django_model_util Choices field. is this package compatible? i ask because i am trying to create a filter that uses the human-readable version of the choices field backing a model field, and can't get it to work. if it is compatible, i'd love a concrete example to follow. thanks...

Hi @dbinetti. Looking over the code, the choices field is just a regular CharField that pulls its choices from the parent model, so it would exhibit the same characteristics as the underlying field.

What are you're trying to accomplish by using the human-readable value instead of the code value? Could you provide a concrete example?

Using the human-readable value is generally problematic, as this is a display value subject to transformation (language translation, capitalization, etc...). The code values are more durable since they aren't transformed.

I'm trying to make the URL human readable (and fungible directly). However, your point about transformation makes good sense. I'll let this go.

I'd say your best bet is to use code values that are human friendly.

eg,

# Use:
STATUSES = (
    ('started', 'Started'),
    ('in_progress', 'In Progress'),
    ('finished', 'Finished'),
    ('errored', 'Errored'),
)

# instead of
STATUSES = (
    ('s', 'Started'),
    ('p', 'In Progress'),
    ('f', 'Finished'),
    ('e', 'Errored'),
)

actually, i'm using integers (order is important) motel_utils allow for a
three-tuple (1,'foo', 'Foo Bar'), so that would potentially work, but i
think i'll just work things on the front end appropriately.

tks
