示例1: ReadOnlyManyToManyTests
class ReadOnlyManyToManyTests(TestCase):

class Meta:

self.instance.save()
self.instance.rel.add(self.anchor)
# A serialized representation of the model instance
self.data = {'rel': [self.anchor.id], 'id': 1, 'text': 'anchor'}
def test_update(self):
"""

relationship. Not updated due to read_only=True

serializer = self.serializer_class(self.instance, data=data)

self.assertEqual(len(ReadOnlyManyToManyModel.objects.all()), 1)
