Hyperlink Class Cannot Be Pickled #3628
Description
Related to #3350, the rest_framework.relations.Hyperlink instances cannot be pickled as demonstrated with this sample:
>>> import pickle
>>> from rest_framework.relations import Hyperlink
>>> link = Hyperlink('http://example.com', 'test')
>>> pickle.loads(pickle.dumps(link))
Traceback (most recent call last):
File "<console>", line 1, in <module>
TypeError: __new__() missing 1 required positional argument: 'name'
For serializers which use the hyperlink relations, this breaks the caching of the response objects since most of the cache backends rely on pickle by default.
