views.py。我的默认用户登录模板，我尝试了下面列出的两种方法，但不知道我在哪里犯了错误 - 我每次都收到一个错误，我的凭据不正确
def signup(request):
if request.method == 'POST':
form = SignUpForm(request.POST)
if form.is_valid():
user = form.save()
user.refresh_from_db() # load the profile instance created by the signal
user.profile.university = form.cleaned_data.get('university')
user.save()
raw_password = form.cleaned_data.get('password1')
user = authenticate(username=user.username, password=raw_password)
#user_login(request, user)
return redirect('main:main_page')
else:
form = SignUpForm()
return render(request, 'signup.html', {'form': form})
def user_login(request):
'''
Using different method for getting username, tried this and didn't work either
if request.method == 'POST':
form = AuthenticationForm(request, data=request.POST)
if form.is_valid():
username = form.cleaned_data.get('username')
password = form.cleaned_data.get('password')
user = authenticate(username=username, password=password)
if user is not None:
login(request,user)
messages.info(request, "Successfully signed in")
return redirect('main:home')
else:
message = 'Sorry, the username or password you entered is not valid please try again.'
return render(request, 'login.html', {'message':message})
else:
message = 'Invalid'
return render(request, 'login.html', {'message':message})
else:
form=AuthenticationForm()
return render(request, 'login.html', {"form":form})
'''
if request.method == 'POST':
username = request.POST.get('username')
password = request.POST.get('password')
user = authenticate(username=username, password=password)
if user is not None:
if user.is_active:
login(request,user)
return HttpResponseRedirect(reverse('index'))
else:
return HttpResponse("Your account was inactive.")
else:
message = 'Sorry, the username or password you entered is not valid please try again.'
return render(request, 'login.html', {'message':message})
else:
message = 'Request failed please try again.'
return render(request, 'login.html', {'message':message})
models.py
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
first_name = models.CharField(max_length=100, blank=True)
last_name = models.CharField(max_length=100, blank=True)
email = models.EmailField(max_length=150)
bio = models.TextField()
university = models.CharField(max_length=30)
def __str__(self):
return self.user.username
@receiver(post_save, sender=User)
def update_profile_signal(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
instance.profile.save()
forms.py
class SignUpForm(UserCreationForm):
university = forms.CharField(max_length=30)
class Meta:
model = User
fields = ('username', 'first_name', 'last_name', 'email','university', 'password1', 'password2',)
应用 urls.py
app_name = 'main'
urlpatterns=[
path('signup/',views.signup,name='signup'),
path('user_login/',views.user_login,name='user_login'),
path('main_page/',views.main_page,name='main_page'),
]
login.html 表单
<form method="POST" action="{% url 'main:user_login' %}/" class="form-signin">
{%csrf_token%}
<div class="form-label-group">
<input type="text" name="username" id="inputText" class="form-control" placeholder="Username" required autofocus>
<br/>
</div>
<div class="form-label-group">
<input type="password" name="password" id="inputPassword" class="form-control" placeholder="Password" required>
</div>
<div class="custom-control custom-checkbox mb-3">
<input type="checkbox" class="custom-control-input" id="customCheck1">
<label class="custom-control-label" for="customCheck1">Remember password</label>
</div>
<input type="submit" class="form-control" name="" value="Login">
<hr class="my-4">
<p>Don't have account? <a href="{% url 'main:signup' %}" id="signup">Sign up here</a></p>
{% if message %}<p style="color: red;">{{message}}</p>{% endif %}
<a href="{% url 'password_reset' %}" id="signup">Forgot Password</a>
</form>
我无法弄清楚为什么我的 Django 不接受正确的凭据。我的代码的哪一部分似乎不正确？
