爲什麼Django認證不能識別request.user變量？

我正在使用Django 1.10。我有以下設置：爲什麼Django認證不能識別request.user變量？

settings.py：

INSTALLED_APPS = [ 
    'django.contrib.admin', 
    'django.contrib.auth', 
    'django.contrib.contenttypes', 
    'django.contrib.sessions', 
    'django.contrib.messages', 
    'django.contrib.staticfiles', 
    'IFTHQ', 
    'rest_framework' 
] 

MIDDLEWARE = [ 
    'django.middleware.security.SecurityMiddleware', 
    'django.contrib.sessions.middleware.SessionMiddleware', 
    'django.middleware.common.CommonMiddleware', 
    'django.middleware.csrf.CsrfViewMiddleware', 
    'django.contrib.auth.middleware.AuthenticationMiddleware', 
    'django.contrib.messages.middleware.MessageMiddleware', 
    'django.middleware.clickjacking.XFrameOptionsMiddleware', 
]

Views.py：

from django.shortcuts import render 
from IFTHQ import models 
from django.contrib.auth.decorators import login_required 
# Create your views here. 


def home(request): 
    """A view of all bands.""" 
    return render(request, 'IFTHQ/publicpages/front.html') 


@login_required(login_url="login/") 
def dashboard(request): 
    member = models.Member.objects.get(id=request.user.id) 
    data = {} 
    data["profile"] = member 
    return render(request, 'IFTHQ/dashboard/dashboard.html', {"data": data}) 

@login_required(login_url="login/") 
def membership(request): 
    data = {} 
    data["profile"] = member 
    return render(request, 'IFTHQ/dashboard/membership.html', {"data": data})

我證實，有一名成員在成員對象，但是，當我登錄時，我得到這個錯誤：

它似乎沒有找到request.user.id的成員。我錯過了什麼？謝謝。

更新1：會員型號：

class Member(models.Model): 
    User = models.OneToOneField(User, related_name='user') 
    FID = models.FloatField() 
    backup_email = models.CharField(max_length=512) 
    FName = models.CharField(max_length=100) 
    MName = models.CharField(max_length=100, blank=True) 
    LName = models.CharField(max_length=100) 
    Avatar = models.FileField(upload_to='Avatar/%Y/%m/%d', blank=True) 
    Cover = models.FileField(upload_to='Cover/%Y/%m/%d', blank=True) 
    Facebook = models.URLField(default='', blank=True) 
    GooglePlus = models.URLField(default='', blank=True) 
    Twitter = models.URLField(default='', blank=True) 
    Website = models.URLField(default='', blank=True) 
    Bio = models.TextField(default='', blank=True) 
    GENDER_CHOICES = (
     ('M', 'Male'), 
     ('F', 'Female'), 
    ) 
    Gender = models.CharField(max_length=1, choices=GENDER_CHOICES) 
    Hair_Choices = (
     ('Blond', 'Blond'), 
     ('Black', 'Black'), 
     ('Brown', 'Brown'), 
     ('Brunette', 'Brunette'), 
     ('Red', 'Red'), 
     ('Auburn', 'Auburn'), 
     ('Gray', 'Gray'), 
     ('White', 'White'), 
     ('Colorful', 'Colorful'), 
     ('None', 'None'), 
     ('N/A', 'Not Applicable') 
    ) 
    Hair = models.CharField(max_length=25, choices=Hair_Choices) 
    Height = models.FloatField() 

    def __str__(self): 
     return self.FName + " " + self.LName 

    def shortrank(self): 
     return Rank.objects.filter(User=self.id).order_by("-date_promoted")[0].Rank.SName 

    def currentrank(self): 
     return Rank.objects.filter(User=self.id).order_by("-date_promoted")[0].Rank.LongName 

    def rank_img(self): 
     return Rank.objects.filter(User=self.id).order_by("-date_promoted")[0].Rank.image 

    def primary_address(self): 
     return MemberAddress.objects.get(AddressFK=self.id, Default=True) 

    def primary_phone(self): 
     return MemberPhone.objects.get(PhoneFK=self.id, Default=True) 

    def awards(self): 
     return Award.objects.filter(Member=self.id)

這張截圖顯示連接確實存在。

更新2： models.py：

class Member(models.Model): 
    User = models.OneToOneField(User) 
    ...<More>...

Views.py：

@login_required(login_url="login/") 
def dashboard(request): 
    member = request.user.member 
    data = {} 
    data["profile"] = member 
    return render(request, 'IFTHQ/dashboard/dashboard.html', {"data": data})

「我確認了成員對象中有一個成員」你是什麼意思？「Member」類是什麼樣的？ –

因爲根本沒有一個id等於相關用戶ID的成員？這裏'get_object_or_404'可能更合適。 – Evert

好的。我更新了這個問題。這表明模型和價值確實存在。 – arcee123

request.user.id爲您提供用戶表中的ID。如果你想獲取相關成員，那麼你應該過濾user字段，而不是id字段。

member = models.Member.objects.get(user=request.user.id)

如果從外鍵刪除related_name='user'，那麼你可以簡單地做：

member = request.user.member

隨着related_name='user'，你可以做member = request.user.user。然而，這是令人困惑的，因爲關注後退給你Member，而不是User。

好的。我做了第一個建議，UPDATE 2顯示了這個響應。我只是不明白爲什麼這可以在我的本地機器上運行，但是其他服務器會死機。非常感謝。 – arcee123

如錯誤所述，您尚未爲服務器數據庫中的登錄用戶創建一個「成員」。你或者需要確保你總是在'User'的同時創建'Member'，或者你需要讓你的代碼處理'DoesNotExist'異常。 – Alasdair

爲什麼Django認證不能識別request.user變量？
