未找到页面 (404) 请求方法：GET 请求 URL：http://127.0.0.1:8000/accounts/signup in DJANGO 即使 url 已正确映射

Question

Below is the urls.py file of sub-app accounts

from django.urls import path
from . import views 

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

This views.py of accounts

def signup(request):
    if request.method == 'POST':

        firstname = request.POST['first_name']
        lastname = request.POST['last_name']
        username = request.POST['username']
        password1 = request.POST['password1']
        password2 = request.POST['password2']
        email = request.POST['email']

        if password1==password2:
                user = User.objects.create_user(firstname =first_name ,lastname =last_name ,username =username , email=email, password=password1)
                user.save();
                print("USER CREATED SUCCESSFULLY")
                return redirect('login.html')
    else:
        return redirect('signup.html')

I have even mapped the url in main url.py also, but still it is showing error. below is the signup.html

The signup.html file

<form action="signup" method="POST">
            {% csrf_token %}
            <input type="text" name="first_name" placeholder="FIRST NAME"><br>
            <input type="text" name="last_name" placeholder="LAST NAME"><br>
            <input type="text" name="username" placeholder="USERNAME"><br>
            <input type="email" name="email" placeholder="EMAILID"><br>
            <input type="password" name="password1" placeholder="PASSWORD"><br>
            <input type="password" name="password2" placeholder="CONFIRM PASSWORD"><br>
            <input type="submit">

can anyone please help me out with this problem, i am not getting what went wrong. It is displaying page not found error.

Answer 1

you need to include accounts.urls in project urls.py (ie,) which folder contains settings.py

for example: let i am assumed that you create project Todo

Todo    
 - accounts
    - __init__.py
    - models.py
    - urls.py
    - views.py
    - apps.py
    - tests.py

 - Todo
    - __init__.py
    - urls.py
    - wsgi.py
    - settings.py

Todo/urls.py you need to include accounts.urls

from django.conf.urls import include, path
app_name = "Todo"

urlpatterns = [
    # Examples:
     path(r'^accounts/', include('accounts.urls', namespace="Account")),
]

you need to accounts apps in file settings.py application definition list

# Application definition

INSTALLED_APPS = [
    'accounts',
     ......
    'django.contrib.auth',
]
