无法将关键字“用户名”解析为字段。选项有：城市、身份证、电话等

我想就这些问题寻求帮助。我确实知道这似乎与同一问题的其他问题相似，但我环顾四周，发现没有什么可以真正解决我的问题。顺便说一句，这是我第二次在这里提问，所以请告诉我这条消息是否太长。谢谢！

我将 AllAuth 与 Django 1.8 和 Python 3.5 一起使用

我想根据 AllAuth 提供的用户名实现一个简单的个人资料页面。问题是，我没有在模型中指定用户名或电子邮件字段，我只是对其进行了扩展以添加一些我想要的信息，但 Django 似乎只识别了我扩展的字段，并且我无法找到从 AllAuth 获取该信息的正确方法。

这是我的代码（一些自定义字段是葡萄牙语，但所有核心内容都是英语）：

配置文件/models.py

from django.conf import settings
from django.db import models
from django.db.models.signals import post_save
from django.utils.encoding import smart_text

UF_CHOICES = (
    ('SP', 'SP'),
    ('RJ', 'RJ')
)

class Profile(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL)

    uf = models.CharField(
                        max_length = 2,
                        blank=False,
                        default = 'SP',
                        choices = UF_CHOICES,
                        verbose_name = 'UF',
                        )
    cidade = models.CharField(max_length=120, null=True, blank=True, default="Rio de Janeiro")
    telefone = models.CharField(max_length = 20, blank=True, null=True, verbose_name = 'Telefone para Contato')

    def __str__(self):
        return smart_text(self.user)



def post_save_user_model_receiver(sender, instance, created, *args, **kwargs):
    if created:
        try:
            Profile.objects.create(user=instance)
        except:
            pass

post_save.connect(post_save_user_model_receiver, sender=settings.AUTH_USER_MODEL)

配置文件/forms.py

from django import forms
from .models import Profile

class ProfileForm(forms.ModelForm):
    class Meta:
        model = Profile
        fields = [
            "uf",
            "cidade",
            "telefone",
        ]

    def profile(self, request, user):
        user.uf = self.cleaned_data['uf']
        user.cidade = self.cleaned_data['cidade']
        user.telefone = self.cleaned_data['telefone']
        user.save()

配置文件/admin.py

from django.contrib import admin

# Register your models here.

from .models import Profile

admin.site.register(Profile)

配置文件/views.py

from django.contrib.auth.decorators import login_required
from django.shortcuts import render, get_object_or_404
from .models import Profile

# Create your views here.

@login_required
def profile_detail(request, username=None):
    obj = get_object_or_404(Profile, username=username)
    context = {
        "object": obj,
    }
    template = 'profile_detail.html'
    return render(request, template, context)

配置文件/适配器.py[注意，这里显示了用户名]就像文档指定的那样：http://django-allauth.readthedocs.io/en/latest/advanced.html http://django-allauth.readthedocs.io/en/latest/advanced.html

from django.conf import settings
from allauth.account.adapter import DefaultAccountAdapter

class MyAccountAdapter(DefaultAccountAdapter):

    def get_login_redirect_url(self, request):
        path = "/profiles/{username}/"
        return path.format(username=request.user.username)

配置文件/urls.py

from django.conf.urls import url
from .views import profile_detail

urlpatterns = [

    url(r'^(?P<username>[\w.@+-]+)/$', profile_detail, name='profile_detail'),
]

最后，报错信息：

好吧，我发现了这个问题。我花了很长时间，因为我没有以正确的方式看待它。

问题不在于代码本身，更多的是哪个模型实际存储了我需要的信息。在本例中，我想从数据库中获取用户和配置文件信息，但没有意识到它们是两个独立的模块。我试图从用户存储的个人资料信息中获取。

原文是：

profile.views.py（旧的且错误的）

from django.contrib.auth.decorators import login_required
from django.shortcuts import render, get_object_or_404
from .models import Profile

# Create your views here.

@login_required
def profile_detail(request, username=None):
    obj = get_object_or_404(Profile, username=username)
    context = {
        "object": obj,
    }
    template = 'profile_detail.html'
    return render(request, template, context)

profile.views.py（新的和工作的）——注意导入如何从 Profile 更改为 User 以及我如何从 obj.profile 创建新用户 obj

from django.contrib.auth.decorators import login_required
from django.contrib.auth.models import User
from django.shortcuts import render, get_object_or_404

# Create your views here.

@login_required
def profile_detail(request, username=None):
    obj = get_object_or_404(User, username=username)
    user = obj.profile
    context = {
        "object": obj,
        "user": user,
    }
    template = 'profile_detail.html'
    return render(request, template, context)

非常感谢您的帮助！
