所以，我已经试着解决这个问题好几天了，但实际上我似乎没有运气解决它

对于我的项目，我正在Django创建一个学生成绩管理系统，我遇到的问题是，每次用户单击主页/登录页面上的注册按钮时，我都会收到一个错误，因为我没有成功地重新路由用户。具体来说，我得到的错误是，它说，页面未找到

我尝试将用户重新路由到的页面位于另一个应用程序中。因此，我尝试将用户路由到该应用程序的基本url，从那里，它将弹出一个视图

以下是登录页面/主页（App1）上my urls.py的代码

from django.urls import re_path
from django.shortcuts import redirect
# import signUpPage.views as signupview
from . import views


urlpatterns = [
    re_path(r'^$', views.login, name='login'),
    # re_path('signUpPage', signupview.register, name='signUpPage')
    # re_path('')
]

以下是登录页面/主页（App1）上my forms.py的代码

from crispy_forms.helper import FormHelper
from crispy_forms.layout import Fieldset, Layout


class loginForm(forms.Form):
    UserName = forms.CharField(
        label="Username",
        help_text="Please enter your username",
        widget=forms.TextInput(attrs={"placeholder":"Username"}),
        required=False
    )

    Password = forms.CharField(
        label="Password",
        help_text="Enter your password",
        widget=forms.TextInput(attrs={"placeholder":"Password"}),
        required=False
    )

以下是登录页面/主页（App2）上my views.py的代码

from django.shortcuts import render, redirect, HttpResponseRedirect
from . forms import loginForm
from django.urls import re_path
from signUpPage.views import register
# from .models import <Insert whatever it is you want to import, but it might not be nexessary>


def login(request):
    if request.method == "POST":
        redirect('signUpPage')
        if request.POST.get("signup"):
            register()
    else:
        form = loginForm(request.GET)
        return render(request, 'homePage/homePage.html', {"form": form})

以下是登录页面/主页（App1）的html

在urls.py文件中，可以添加一个名为app_name="app_name"的常量，在HTML链接或按钮中，只需使用url标记，如{% url app_name:path_name %}

它告诉Django您正在谈论哪个特定的urls.py文件
