python - Django why can't I authenticate a user? -
i'm trying create user authentification form using django +1.8 encountered problem, when press form submit button, nothing happens, page reloading instead of loging in, why?
here code:
views.py
from django.shortcuts import render django.contrib.auth import authenticate django.contrib.auth import login auth_login django.contrib.auth import logout auth_logout # create views here. def user(request): context = {} return render(request, 'user.html', context) def login(request): context = {} if request.method == "post": username = request.post['username'] password = request.post['password'] user = authenticate(username=username, password=password) if user not none: if user not none: auth_login(request, user) else: context['error'] = 'non active user' else: context['error'] = 'mauvais nom d\'utilisateur ou mot de passe' else: context['error'] = '' return render(request, 'user.html', context) def logout(request): context = {} if request.method == "post": auth_logout(request) else: context['error'] = 'une erreur s\'est produite.' return render(request, 'user.html', context) urls.py
django.conf.urls import url utilisateur import views urlpatterns = [ url(r'^$', views.user, name="user"), url(r'^login$', views.login, name='login'), url(r'^logout$', views.logout, name='logout'), ] user.html
{% block content %} {% if user.authenticated %} <p>{{ user.username }}</p> <a href="logout?">logout</a> {% else %} <form method="post" action="login"> {% csrf_token %} <p>username:<input type="text" name="username"></p> <p>password:<input type="password" name="password"></p> <input value="se connecter" type="submit"> </form> {% endif %} {% endblock %} i thought middlewares useful in order solve issue.
middleware_classes = [ 'django.middleware.security.securitymiddleware', 'django.contrib.sessions.middleware.sessionmiddleware', 'django.middleware.common.commonmiddleware', 'django.middleware.csrf.csrfviewmiddleware', 'django.contrib.auth.middleware.authenticationmiddleware', 'django.contrib.auth.middleware.sessionauthenticationmiddleware', 'django.contrib.messages.middleware.messagemiddleware', 'django.middleware.clickjacking.xframeoptionsmiddleware', ] 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], i think problem comes context_instance=requestcontext(request), how can solve ?
actually authentication working properly. need make corrections like, user.authemticated user.is_authenticated , change logout function , url on template
user.html:
{% block content %} {% if user.is_authenticated %} <p>{{ user.username }}</p> <a href="/logout">logout</a> {% else %} <form method="post" action="login"> {% csrf_token %} <p>username:<input type="text" name="username"></p> <p>password:<input type="password" name="password"></p> <input value="se connecter" type="submit"> </form> {% endif %} {% endblock %} views.py
from django.shortcuts import render django.contrib.auth import authenticate django.contrib.auth import login auth_login django.contrib.auth import logout auth_logout # create views here. def user(request): context = {} return render(request, 'user.html', context) def login(request): context = {} if request.method == "post": username = request.post['username'] password = request.post['password'] user = authenticate(username=username, password=password) if user not none: if user.is_active: auth_login(request, user) else: context['error'] = 'non active user' else: context['error'] = 'mauvais nom d\'utilisateur ou mot de passe' else: context['error'] = '' return render(request, 'user.html', context) def logout(request): context = {} auth_logout(request) return render(request, 'user.html', context)
