As all source files import unicode_literals, type('') is always
equivalent to six.text_type (str on Python 3 and unicode on Python 2).
Removes the need to call type(), is more explicit, and will be easier to
catch places to change for when it is time to eventually drop Python 2.
* Add Meta.fields = '__all__' to serializer classes where required.
* Add explicit on_delete=models.CASCADE to ForeignKey fields.
* Use '.remote_field' and '.model' in preference to '.rel' and '.to' when inspecting model fields.
* Use new value_from_object in preference to internal _get_val_from_obj
Previously an extra list wrapped nested validation errors raised from serializer's validate() methods.
That was inconsistent with the format of validation errors raised by validate_<fieldname> methods.
i.e. these two resulted in *different* behaviour:
def validate_foo(self):
raise ValidationError(['bar'])
def validate(self):
raise ValidationError({'foo': ['bar']})
* Get rid of runtests.py
* Moved test code from rest_framework/tests and rest_framework/runtests to tests
* Invoke py.test from setup.py
* Invoke py.test from Travis
* Invoke py.test from tox
* Changed setUpClass to be just plain setUp in test_permissions.py
* Updated contribution guideline to show how to invoke py.test
