DurationField missing in SimpleMetadata.label_lookup

[smt-insens]

Context:

I made an HTTP OPTIONS request. In the response I have the type of each field. I have a duration field so I expected to see something like "duration" as type but instead I have "field".

Solution:

After investigation I found that DurationField is missing in SimpleMetadata.label_lookup

This is probably due to the fact DurationField was added to Django after the other fields. The person who added DurationField probably forgot to add it to the label_lookup.

The following line should be added to label_lookup: serializers.DurationField: 'duration',

django-rest-framework/rest_framework/metadata.py
