Django 使用q.save()的IntegrityError:不能为NULL

Django 使用q.save()的IntegrityError:不能为NULL,django,Django,我不知道为什么会出错。这里是观点和线索 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(scor

我不知道为什么会出错。这里是观点和线索

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

表结构不正确,需要:

class Results(models.Model):
    word = models.ForeignKey(Word)
    score = models.IntegerField(blank=True, null=True)
之后,删除此表并运行命令:

python manange.py syncdb
#
blank
选项表单验证是否需要此节点


#
null
选项它是为您的数据库准备的(null true或false)

请发布您的实际代码。对于这里的模型,
Word
没有
分数集
——它有
结果集
。不确定实际代码是什么意思。我有模型、视图、URL和模板。我还没有使用URL和模板,所以我只是发布了模型和视图。重点是,这段代码将给出与您显示的不同的错误-它将为
分数集
提供
属性错误。我又跑了一遍。您会谈论代码的其余部分是什么?只是好奇,为什么要在代码的第6行中进行此查询?不幸的是,仍然存在相同的问题。
