视图中的TypeError：字段应为数字，但得到了''

问题描述

这是我第一次在堆栈溢出中发布问题，所以请耐心：D 我正在尝试从表单创建人员模型，但错误始终存在

这是我的模型文件：

class CustomUser(AbstractUser):
    user_type_data = ((1,"HOD"),(2,"Consultant"))
    user_type = models.CharField(default=1,choices=user_type_data,max_length=10)


class Consultant(models.Model):
    CHOICES = (
        ('P','au paiement'),('J15','J+15'),('J30','J+30'),)

    id = models.AutoField(primary_key=True)
    admin = models.OneToOneField(CustomUser,on_delete=models.CASCADE)
    client_id=models.ForeignKey(Client,on_delete=models.CASCADE,default=1)
    tarif_facturation = models.IntegerField(blank=True,null=True)
    tarif_Consultant = models.IntegerField(blank=True,null=True)
    cnss = models.IntegerField(blank=True,null=True)
    rib = models.IntegerField(blank=True,null=True)
    paiement = models.CharField(max_length=300,choices=CHOICES)
    profile_pic = models.FileField(blank=True,null=True)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now_add=True)
    objects = models.Manager()

@receiver(post_save,sender=CustomUser)
def create_user_profile(sender,instance,created,**kwargs):
    if created:
        if instance.user_type == 1:
            AdminHOD.objects.create(admin=instance)
        if instance.user_type == 2:
            Consultant.objects.create(admin=instance,client_id=Client.objects.get(id=1),tarif_Consultant="",tarif_facturation="",cnss="",rib="",paiement="")


@receiver(post_save,sender=CustomUser)
def save_user_profile(sender,**kwargs):
    if instance.user_type==1:
        instance.adminhod.save()
    if instance.user_type==2:
        instance.consultant.save()

我的观点：

def add_staff_save(request):
    if request.method!="POST":
        return HttpResponse("Method Not Allowed")
    else:
        email=request.POST.get("email")
        password=request.POST.get("password")
        first_name=request.POST.get("first_name")
        last_name=request.POST.get("last_name")
        username=request.POST.get("username")
        client_id=request.POST.get("client")
        tarif_facturation=request.POST.get("tarif_facturation")
        tarif_Consultant=request.POST.get("tarif_Consultant")
        cnss = request.POST.get("cnss")
        rib = request.POST.get("rib")
        paiement = request.POST.get("paiement")
        #try:
        user=CustomUser.objects.create_user(username=username,password=password,email=email,last_name=last_name,first_name=first_name,user_type=2)
        client_obj=Client.objects.get(id=client_id)
        user.consultants.client_id=client_obj
        user.consultant.tarif_facturation=tarif_facturation
        user.consultant.tarif_Consultant=tarif_Consultant
        user.consultant.cnss=cnss
        user.consultant.rib=rib
        user.consultant.paiement=paiement
        user.save()

异常类型：/ add_staff_save处的ValueError 异常值：字段“ tarif_facturation”应为数字，但获得了“。”。

解决方法

问题出在您在Conslutant中创建post_save对象

Consultant.objects.create(
    admin=instance,client_id=Client.objects.get(id=1),tarif_Consultant="",tarif_facturation="",cnss="",rib="",paiement=""
)

tarif_facturation是IntegerField，但在此您的值是一个空字符串。将该值设为数字，该错误将得到解决。

不过，对于在Consultant创建中设置的许多其他属性，您所做的事情完全相同，因此只需确保您的值与模型所需的类型匹配即可。

像这样的东西

Consultant.objects.create(
    admin=instance,tarif_facturation=1,)
