python - 访问我的网站页面后无法登录管理页面

Question

我在我的管理部分创建了一个 super 用户。之后我可以登录管理页面。但是每当我尝试访问某些 myapp 页面然后再次想要访问管理页面时，它会显示此错误“请输入员工帐户的正确用户名和密码。请注意，这两个字段可能区分大小写。”我尝试了多次。我可以使用上次创建的同名创建一个新的 super 用户。这是两张截图:
Login Error
creating superuser

如何解决这个问题？

更新:

表单.py

 from django.contrib.auth.models import User
    from django.forms import ModelForm
    from django import forms
    from .models import Profile

    class UserForm(forms.ModelForm):
        password= forms.CharField(widget= forms.PasswordInput)
        class Meta:
            model = User
            fields = ('username','email','password')

    class ProfileForm(forms.ModelForm):

        class Meta:
            model = Profile
            fields = ('full_name','codeforces_id','Uva_Id')

模型.py

from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.dispatch import receiver

class Profile(models.Model):
    user = models.OneToOneField(User,on_delete=models.CASCADE)
    full_name = models.CharField(max_length=256, blank=False)
    codeforces_id = models.CharField(max_length=256, blank=False)
    Uva_Id = models.CharField(max_length=256, blank=False)
    @receiver(post_save, sender=User)
    def create_user_profile(sender, instance, created, **kwargs):
        if created:
            Profile.objects.create(user=instance)

    @receiver(post_save, sender=User)
    def save_user_profile(sender, instance, **kwargs):
        instance.profile.save()

views.py:

            username = user_form.cleaned_data['username']
            user.set_password(password)

            user.save()
            profile_form.save()

            # auto login 
            user = authenticate(username =username, password = password)

            if user is not None:

        return render(request, 'website/registration_form.html',{

            'profile_form':profile_form
            })

我认为你把事情过于复杂化了。所以尝试这样:

# forms


class UserForm(forms.ModelForm):
    password = forms.CharField(widget= forms.PasswordInput)
    full_name = forms.CharField()
    codeforces_id = forms.CharField()
    Uva_Id = forms.CharField()

    class Meta:
        model = User
        fields = ('username','email','password', 'full_name', 'codeforces_id', 'Uva_Id') 


    def save(self, commit=True):
        full_name = self.cleaned_data.pop('full_name')
        codeforces_id = self.cleaned_data.pop('codeforces_id')
        uva_Id = self.cleaned_data.pop('Uva_Id')
        user = super(UserForm, self).save(commit=False)
        password = self.cleaned_data.get('password')
        username = self.cleaned_data.get('username')
        user.set_password(password)
        user.save()
        Profile.objects.create(
            user=user,
            full_name = full_name,
            codeforces_id = codeforces_id,
            Uva_Id = uva_id
        )
        authenticate(username=username, password=password)
        return user

# view

class UserFormView(CreateView):
    form_class = UserForm
    template_name = 'some_template.html'


# template

<form action="/your-name/" method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Submit">
</form>

# Also you can remove the signal related codes from Profile Model as well
