无法使用Django将数据插入数据库

Question

我是 Django 的初学者，我正在尝试将值插入 auth_user table。但不知何故我无法这样做。我试图解决，但一切似乎都是徒劳的。

这是我的 views.py:

from django.shortcuts import render,redirect
from django.contrib.auth.models import User, auth
# Create your views here.
def register(request):

     if request.method == 'POST' : 
         firstname = request.POST['firstname'] 
         lastname = request.POST[ 'lastname']
         emailid= request.POST['emailid']
         username= firstname+lastname
         passwordl = request.POST['password'] 

         user = User.objects.create_user(username=username,first_name=firstname,last_name=lastname)
         user.save()
         
         return redirect('admin/')
     else:
        return render(request, 'employee/register.html')

这是模板（我已经下载了）

这个urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('register/', views.register, name='register'),
]

我还可以注意到，当我点击注册按钮时，我收到一个错误，提示 employee\register\register 被调用，但它不存在，这很奇怪，因为要获取 employee\register。

Answer 1

此处您缺少在用户中插入密码 table...

另一种方式（推荐）：

forms.py:

from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User

class SignUpForm(UserCreationForm):
    class Meta:
        model = User
        fields = ["username","first_name","last_name","email"]
        labels = {'email':'Email'}

views.py:

def register(request):
    if request.method=="POST":
        fm = SignUpForm(request.POST)
        if fm.is_valid():
            fm.save()
            return HttpResponseRedirect("admin/")
    else:
        fm = SignUpForm()
    return render(request,'signup.html',{"fm":fm})

Answer 2

我查看了您的模板，发现您在第 196 行将表单的操作设置为 register/。因此只需将其更改为 \employee\register 并从您在 urls.py 中创建的 url 中删除正斜杠，如下所示：

urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('register', views.register, name='register'),
]

模板

...
<form action="\employee\register" method="post">
     {% csrf_token %}
...

希望这能解决您的问题。
