python之Django之IntegrityError之非空约束

当我的表单字段为空时，出现此错误:

IntegrityError 在/inscription NOT NULL 约束失败:le_site_inscrit.age

我的模型:

class Inscrit(models.Model): 
    user = models.OneToOneField(User) 
    age = models.IntegerField(max_length=2, null=True, default=None) 

我在 forms.html 中的表单:

class inscriptionForm(forms.Form): 
    mail = forms.EmailField(max_length=100) 
    firstname = forms.CharField() 
    username = forms.CharField() 
    age = forms.IntegerField(required=False) 
    mdp = forms.CharField(widget=forms.PasswordInput) 

我的观点:

def inscription(request): 
    error = False 
    if request.method == "POST": 
        form = inscriptionForm(request.POST) 
        if form.is_valid(): 
            mail = form.cleaned_data["mail"] 
            mdp = form.cleaned_data["mdp"] 
            username = form.cleaned_data["username"] 
            userfirstname = form.cleaned_data["firstname"] 
            age = form.cleaned_data["age"] or None 
            u = User.objects.create_user(username,mail,mdp) 
            u.first_name = userfirstname 
            u.save() 
            inscrit = Inscrit() 
            inscrit.user = u 
            if age is not None : 
                inscrit.age = age 
            inscrit.save() 
            return redirect(reverse(home)) 
        else : 
            error = True 
    else : 
        form = inscriptionForm() 
    return render(request,"zouya/inscription.html",locals()) 

谢谢

请您参考如下方法:

将 blank=True 添加到您的模型字段定义中:

class Inscrit(models.Model): 
    user = models.OneToOneField(User) 
    age = models.IntegerField(max_length=2, null=True, blank=True, default=None)
