I'm want to log a user in, in simple web site. i tried to create my own login authentication but it send this error:
AttributeError at /login/ , 'QuerySet' object has no attribute 'pk'
this is the code (views.py) :
...
from django.contrib.auth import login as login_module
def login(request):
if request.method == "POST":
Login = LoginFrom(request.POST)
if Login.is_valid():
user = Login.cleaned_data
if User.objects.filter(username=user['username']).exists():
user_info = User.objects.filter(username=user['username'] ,
password=user['password']).values('name')
if user_info.exists():
login_module(request, user_info)
messages.success(request, 'welcome {}'.format(user_info[0]['name'] ) , 'welcome_message')
else:
messages.error(request, 'wrong password', 'password_message')
else:
messages.error(request, 'username doesn\'t exist', 'username_message')
else:
Login = LoginFrom()
return render(request, 'login.html')
then i replace it with this code that's from django document; it get me into another problem which is always return 'None':
views.py
...
...
from django.contrib.auth import authenticate
from django.contrib.auth import login as login_module
def login(request):
if request.method == "POST":
Login = LoginFrom(request.POST)
if Login.is_valid():
cd = Login.cleaned_data
user = authenticate(request, username = cd['username'], password = cd['password'])
if user is not None:
login_module(request, user)
messages.success(request, 'login', 'welcome_message')
else:
messages.error(request, 'error (none)', 'error_message')
else:
Login = LoginFrom()
return render(request, 'login.html')
(form.py) in both way:
class LoginFrom(forms.Form):
username = forms.CharField()
password = forms.CharField(widget=forms.PasswordInput)
login.html:
<!DOCTYPE html>
<html>
<head><title>login</title></head>
{% include 'header.html' %}
<body class="background">
<form id="login_form" action="" method="POST">
{% csrf_token %}
<p class="lead">login to your account</p>
<div class="form-group">

<div class="input-group">
<div class="input-group-text" id="basic-addon1"><i class="bi bi-people"></i></div>
<input type="text" name="username" class="form-control" placeholder="Enter Your Username"required>
</div>
<div>
{% if messages %}
{% for message in messages %}
{% if 'username_message' in message.tags %}
<div class="text-danger" > {{message}} </div>
{% endif %}
{% endfor %}
{% endif %}
</div>
</div>
<div class="form-group">

<div class="input-group">

{% if messages %}
{% for message in messages %}
{% if 'password_message' in message.tags %}

{% endif %}
{% endfor %}
{% endif %}
</div>
</div>
<br>
<button class="btn btn-outline-secondary" type="submit" name="login" value="login" >Login</button>
<div>
{% if messages %}
{% for message in messages %}
{% if 'welcome_message' in message.tags %}
<div class="text-warning text-center" > {{message}} </div>
{% endif %}
{% endfor %}
{% endif %}
</div>
</form>
</body>
</html>
models.py
class User(models.Model):
name = models.CharField(max_length=100)
email = models.EmailField()
username = models.CharField(max_length=100)
password = models.CharField(max_length=100)
comment_count = models.IntegerField(default=0)
