【问题描述】：
我有以下问题：
我正在尝试保存用户和个人资料，但是当我尝试在我的数据库中发布时出现以下错误：
null value in column "user_id" violates not-null constraint
DETAIL: Failing row contains (16, 2018-01-01 00:00:00+00, null, colegio monserrat, femenino, null, primero, social, null, null, null, null, null, null, null, null, null, null, Ciencias mundo contemporáneo, Historia de la filosofía, Lengua catalana y literatura I, Lengua catalana y literatura II, Lengua extranjera I, Lengua extranjera II, Lengua castellana y literatura I, Lengua castellana y literatura II, fisica, matematicas, quimica, matematicas, matematicas, matematicas, matematicas, fisica, Educación física, Filosofía, null, Historia).
我的模型如下：
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
birth_date = models.DateTimeField(null=True, blank=True)
sex = models.CharField(null=True, max_length=50, choices=SEX_CHOICES)
school = models.CharField(null=True, max_length=50, choices=SCHOOL_CHOICES)
schoolCode = models.IntegerField(null=True)
bachelorCourse = models.CharField(null=True, max_length=50, choices=COURSE_CHOICES)
bachelorModality = models.CharField(null=True, max_length=50, choices=COURSE_MODALITY_CHOICES)
password = models.CharField(null=True, max_length=50)
password2 = models.CharField(null=True, max_length=50)
obligatorySubjectOne1 = models.CharField(null=True, max_length=100, default='Lengua catalana y literatura I')

obligatorySubjectSix1 = models.CharField(null=True, max_length=100, default='Filosofía')
optionalSubjectOne1 = models.CharField(null=True, max_length=100, choices=SUBJECTS_CHOICES_OPTIONALLY)
optionalSubjectTwo1 = models.CharField(null=True, max_length=100, choices=SUBJECTS_CHOICES_OPTIONALLY)

optionalSubjectFour2 = models.CharField(null=True, max_length=100, choices=SUBJECTS_CHOICES_OPTIONALLY)
optionalSubjectFive2 = models.CharField(null=True, max_length=100, choices=SUBJECTS_CHOICES_OPTIONALLY)
avatarChoose = models.CharField(null=True, max_length=50) # imageField
interest = models.CharField(null=True, max_length=50, choices=SUBJECTS_CHOICES_OPTIONALLY)
interestOne = models.CharField(null=True, max_length=50, choices=SUBJECTS_CHOICES_OPTIONALLY)
interestTwo = models.CharField(null=True, max_length=50, choices=SUBJECTS_CHOICES_OPTIONALLY)
university = models.CharField(null=True, max_length=50, choices=SUBJECTS_CHOICES_OPTIONALLY)
universityOne = models.CharField(null=True, max_length=50, choices=SUBJECTS_CHOICES_OPTIONALLY)
universityTwo = models.CharField(null=True, max_length=50, choices=SUBJECTS_CHOICES_OPTIONALLY)
meanCourse = models.FloatField(null=True)
forms.py中的ModelForm如下：
class UserEditForm(forms.ModelForm):
class Meta:
model = User
fields = ('first_name', 'last_name', 'email')
labels = {
"first_name": "Nombre",
"last_name": "Apellidos",
"email": "Correo"
}
widgets = {
"first_name": forms.TextInput(attrs={'class': 'form-control'}),
"last_name": forms.TextInput(attrs={'class': 'form-control'}),
"email": forms.TextInput(attrs={'class': 'form-control'})
}
# build the some edit profile register variables
class ProfileEditForm(forms.ModelForm):
class Meta:
model = Profile
Profile.obligatorySubjectOne1 = "Castellano"
Profile.obligatorySubjectFive1 = "Castellano"
fields = ('birth_date',
'sex',
'school',
'bachelorCourse',
'bachelorModality',
'optionalSubjectOne1',
'optionalSubjectTwo1',
'optionalSubjectThree1',
'optionalSubjectFour1',
'optionalSubjectOne2',
'optionalSubjectTwo2',
'optionalSubjectThree2',
'optionalSubjectFour2'
)
labels = {
"birth_date": "Fecha de nacimiento",
"sex": "Sexo",
"school": "Escuela",
"bachelorCourse": "Curso de bachillerato",
"bachelorModality": "Modalidad de bachillerato",
"optionalSubjectOne1": "Escojer Optativa 1B",
"optionalSubjectTwo1": "Escojer Optativa 1B",
"optionalSubjectThree1": "Escojer Optativa 1B",
"optionalSubjectFour1": "Escojer Optativa 1B",
"optionalSubjectOne2": "Escojer Optativa 2B",
"optionalSubjectTwo2": "Escojer Optativa 2B",
"optionalSubjectThree2": "Escojer Optativa 2B",
"optionalSubjectFour2": "Escojer Optativa 2B"
}
widgets = {
"birth_date": forms.SelectDateWidget(empty_label=("Choose Year", "Choose Month", "Choose Day")),
"bachelorCourse": forms.Select(attrs={'class': 'select'}),
"bachelorModality": forms.Select(attrs={'class': 'select'}),
"optionalSubjectOne1": forms.Select(attrs={'class': 'select'}),
"optionalSubjectTwo1": forms.Select(attrs={'class': 'select'}),
"optionalSubjectThree1": forms.Select(attrs={'class': 'select'}),
"optionalSubjectFour1": forms.Select(attrs={'class': 'select'}),
"optionalSubjectOne2": forms.Select(attrs={'class': 'select'}),
"optionalSubjectTwo2": forms.Select(attrs={'class': 'select'}),
"optionalSubjectThree2": forms.Select(attrs={'class': 'select'}),
"optionalSubjectFour2": forms.Select(attrs={'class': 'select'})
}
最后我保存创建的对象的视图如下：
def register(request):
if request.method == 'POST':
user_form = UserRegistrationForm(request.POST)
profile_form = ProfileEditForm(request.POST)
if user_form.is_valid() and profile_form.is_valid():
# Create a new user object but avoid saving it yet
new_user = user_form.save(commit=False)
new_profile = profile_form.save(commit=False)
# Set the chosen password
new_user.set_password(user_form.cleaned_data['password'])
# Save the User object
new_user.save()
new_profile.save()
return render(request, 'account/register_done.html', {'new_user': user_form, 'new_profile': profile_form})
else:
user_form = UserRegistrationForm()
profile_form = ProfileEditForm()
return render(request, 'account/register.html', {'user_form': user_form, 'profile_form': profile_form})
这是我认为您需要它来了解问题的所有代码。之前，我的代码的注册部分，它工作正常，我不知道问题是否可能是数据库引起的，或者为什么不是所有的指令都在视图中。
如果您能帮助我，请提前感谢您。
traceback的粗体部分如下：
/home/web_unithinks/unithinks/account/views.py in register
new_profile.save() ...

【问题讨论】：
-
顺便说一句，
Profile.obligatorySubjectOne1 = "Castellano"和Profile.obligatorySubjectFive1 = "Castellano"行看起来不正确。目前尚不清楚您要在那里做什么。我会删除这些行。 -
是的，我在做证明的时候放的。
