python - ForeignKey フィールドを持つオブジェクトのテストと作成

Question

いくつかの単体テストを作成しようとしており、この目的のためにいくつかのダミー オブジェクトを作成しています。speaker私は部分的にこのように見えるモデルを持っています:

class speaker(models.Model):
    name = models.CharField(max_length=255)
    email = models.CharField(max_length=255, primary_key=True)
    ...

talk部分的に次のように見えるクラス：

class talk(models.Model):
    title = models.CharField(max_length = 255) 
    ...
    speakers = models.ManyToManyField('speaker') 
    ...

私のテスト設定は次のようになります。

class TalkTest(TestCase):
    def setUp(self):

        speaker.objects.create(
            name = "John Smith",
            email = "john@john.com"
            )

        talk.objects.create(
            title = "Writing unit tests",
            summary = "How to write unit tests",
            speakers = "john@john.com"
            )

    def test_talk_URLs(self):
        testSpeak = speaker.objects.get(name="John Smith")
        testTalk = talk.objects.get(title="Writing unit tests")

        self.assertEqual(testSpeak.email, "john@john.com")

ただし、次のトレースバックエラーが発生します
