我不知道這里會發生什么：模型.pyclass Sound(models.Model):    SEX_CHOICES = (            ('M', 'Male'),            ('F', 'Female')    )    phrase1 = models.CharField(max_length=300)    phrase2 = models.CharField(max_length=300)    language = models.CharField(max_length=50)    num_words = models.PositiveSmallIntegerField(verbose_name="number of words")    num_syllables = models.PositiveSmallIntegerField(verbose_name="number of syllables")    sex = models.CharField(max_length=1, choices=SEX_CHOICES)    voice = models.BooleanField(verbose_name="synthetic voice")    speaker_name = models.CharField(max_length=50)    sound_hash = models.CharField(max_length=40, primary_key=True, editable=False)    key = models.CharField(max_length=200, editable=False, default="", null=True, help_text="Amazon S3 key")表格.pyfrom django import formsclass LessonSoundForm(forms.ModelForm):    class Meta:        model = Sound        fields = ["phrase1", "phrase2", "num_words", "num_syllables"]測試.pyfrom django.test import TestCasefrom forms import LessonSoundFormclass LessonSoundForm(TestCase):    def setUp(self):        self.sound_data = {                "phrase1": "Poop",                "phrase2": "Knuckle",                "num_words": 1,                "num_syllables": 1        }    def test_lesson_sound_form_validates_with_good_data(self):        form = LessonSoundForm(data=self.sound_data)        self.assertTrue(form.is_valid())這看起來非常簡單，所有其他測試都使用ModelForm. 但是，我收到此錯誤：line 20, in test_lesson_sound_form_validates_with_good_data        form = LessonSoundForm(data=self.sound_data)    TypeError: __init__() got an unexpected keyword argument 'data'如果我在沒有data參數的情況下運行它，我會得到：    form = LessonSoundForm(self.sound_data)  File "/usr/lib/python3.6/unittest/case.py", line 397, in __init__    testMethod = getattr(self, methodName)TypeError: getattr(): attribute name must be string這似乎是一個非?；镜陌咐?，我不知道會出現什么問題。我認為這只是一天的結束，我錯過了一些愚蠢的事情。
