Question

我想通过验证sqlite3数据库中是否存在该用户来创建注册表单来注册用户。

这是我的根urls.py文件：

from django.contrib import admin
from django.urls import path, include
urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('orphanageoperations.urls')),
]

子网址文件：

from django.urls import path
from .import views

urlpatterns=[
        path('',views.orphanage_main_page,name='orphanage_main_page'),
        path('signup.html',views.signup,name='signup'),
        path('login.html',views.login,name='login')
        ]

views.py文件

from django.shortcuts import render
from .forms import SignupForm
def signup(request):
    if request.method=='POST':
        form=SignupForm(request.POST)
        if form.is_valid():
            form.save(commit=True)
    else:
        form=SignupForm()

    return render(request,'orphanageoperations/signup.html',{})

models.py

from django.db import models
from django.utils import timezone
from django.conf import settings
# Create your models here.

class Signup(models.Model):
    username=models.CharField(max_length=20);
    usermail=models.CharField(max_length=20,primary_key=True);
    userph=models.CharField(max_length=13);
    userpwd=models.CharField(max_length=20);

    def createUser(self):
        self.username;
        self.usermail;
        self.userph;
        self.userpwd;

forms.py

from django import forms
from .models import Signup

class SignupForm(forms.ModelForm):
    class Meta:
        model= Signup;
        fields=('username','usermail','userph','userpwd',);

signup.html

            if(username==""){
            alert("Please Enter the username");
            return false;
            }
            if(mobilenum==""){

            </div>

        </form>
    </div>

</body>
</html>

错误消息：

Page not found (404)
Request Method: POST
Request URL:    http://127.0.0.1:8000/signup
Using the URLconf defined in heretohelp.urls, Django tried these URL patterns, in this order:

admin/
[name='orphanage_main_page']
signup.html [name='signup']
login.html [name='login']
The current path, signup, didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

要求所有人在这种情况下为我提供帮助，我无法找到错误存在的地方或我做错了什么。预先感谢。
