我不知道爲什麼我得到錯誤。這裏有意見和clesses使用q.save()的IntegrityError:可能不是NULL
from polls.models import Word, Results
def detail(request):
q = Word(type="How do you like")
q.save()
Word.objects.get(pk=1)
q.score_set.create(score=5)
q.score_set.create(score=4)
q.score_set.create(score=3)
q.score_set.create(score=2)
q.score_set.create(score=1)
return render_to_response('/$')
Models.py
from django.db import models
class Word(models.Model):
type = models.CharField(max_length=200)
def __unicode__(self):
return self.type
class Results(models.Model):
word = models.ForeignKey(Word)
score = models.IntegerField()
def __unicode__(self):
return self.score
錯誤:

請發表您的實際代碼。使用這裏的模型,「Word」沒有'score_set' - 它有'results_set'。 –
不確定您的實際代碼是什麼意思。我有模型,視圖,網址和模板。我沒有利用網址和模板,所以我只發佈了模型和視圖。 – ono
問題是,這段代碼會給你顯示的錯誤提供一個不同的錯誤 - 它會爲'score_set'提供一個'AttributeError'。 –
