Объект AnonymousUser не имеет атрибута _meta

Question

views.py код

from django.shortcuts import render,redirect
from django.http import HttpResponse
from django.contrib.auth.forms import UserCreationForm
from tutorial import views
from accounts.form import Registrationform,EditProfileForm
from django.contrib.auth.forms import UserChangeForm,PasswordChangeForm
from django.contrib.auth.models import User
from django.contrib.auth import update_session_auth_hash
# Create your views here.

def home(request):
    numbers=[1,2,3,4,5]
    name="jay"
    args={'myName':name}

    return render(request,'accounts/home.html',args)
def register(request):
    if request.method == "POST":
        form = Registrationform(request.POST)
        if form.is_valid():
            form.save()
            return redirect('/account')
        else:
            return HttpResponse('please fill all the fields and make sure new password must be match')
    else:
        form = Registrationform()
        args={'form' : form}
        return render(request,'accounts/reg_form.html',args)

def view_profile(request):
    args = {'user' : request.user}
    return render(request,'accounts/profile.html',args)

def edit_profile(request):
    if request.method=="POST":
        form = EditProfileForm(request.POST,instance=request.user)
        if form.is_valid():
            form.save()
            return redirect('/account/profile')
    else:
        form  =  EditProfileForm(instance=request.user)
        args = {'form' : form}
        return render(request,'accounts/edit_profile.html',args)

def change_password(request):
    if request.method == "POST":
        form = PasswordChangeForm(data=request.POST,user=request.user)
        if form.is_valid():
            form.save()
            update_session_auth_hash(request, form.user)
            return redirect('/account/profile')
        else:
            return HttpResponse("password doest not match,go back and try again")
    else:
        form = PasswordChangeForm(user=request.user)
        args = {'form' : form}
        return render(request,'accounts/change_password.html',args)

, а form.py равен

from django import forms
from django.contrib.auth.forms import UserCreationForm,UserChangeForm
from django.contrib.auth.models import User
#from django.forms import RegistrationForm,EditProfileForm

class Registrationform(UserCreationForm):
    email = forms.EmailField(required=True)

    class Meta:
        model = User
        fields = (
        'username',
        'first_name',
        'last_name',
        'email',
        'password1',
        'password2',
        )
    def save(self,commit=True):
        user=super(Registrationform,self).save(commit=False)
        user.first_name= self.cleaned_data['first_name']
        user.last_name=self.cleaned_data['last_name']
        user.email=self.cleaned_data['email']
        if commit:
            user.save()
        return user
class EditProfileForm(UserChangeForm):
    #template_name = '/something/else'
    class Meta:
        model = User
        fields = (
        'email',
        'first_name',
        'last_name',
        'password'
         )

и urls.py

#python -m smtpd -n -c DebuggingServer localhost:1025
from django.contrib import admin
from .import views
from django.conf.urls import url,include
from django.contrib.auth.views import login,logout,password_reset,password_reset_done,password_reset_confirm,password_reset_complete
#from django.urls import path

urlpatterns = [
    url(r'^$',views.home),
    url(r'^login/$',login,{'template_name' : 'accounts/login.html'}),
    url(r'^logout/$',logout,{'template_name' : 'accounts/logout.html'}),
    url(r'^register/$',views.register,name='register'),
    url(r'^profile/$',views.view_profile,name='view_profile'),
    url(r'^profile/edit/$',views.edit_profile,name='edit_profile'),
    url(r'^change-password/$',views.change_password,name='change_password'),
    url(r'^reset-password/$',password_reset,name='reset_password'),
    url(r'^reset-password/done/$',password_reset_done,name='password_reset_done'),
    url(r'^reset-password/confirm/(?P<uidb64>[0-9A-Za-z]+)-(?P<token>.+)/$',
    password_reset_confirm,name='password_reset_confirm' ),
    url(r'^reset-password-complete/$',password_reset_complete,name='password_reset_complete'),


]

Так что, когда я введу URL - "http://127.0.0.1:8000/account/profile/edit/ "это дает мне ошибку

" У объекта 'AnonymousUser' нет атрибута '_meta' '

В чем ошибка? Что я сделал не так?Вот ?и django выдает эту строку с ошибкой

/ usr / local / lib / python2.7 / dist-packages / django / utils / functions.py во внутренней строке 205.

что я должен сделать, чтобы решить эту ошибку?

Answer 1

Лучше использовать login_required декоратор. Он проверит, вошел ли пользователь в систему или нет, без явного ее кодирования.

from django.contrib.auth.decorators import login_required

@login_required
def edit_profile(request):

     if request.method=="POST":
        form = EditProfileForm(request.POST,instance=request.user)
        if form.is_valid():
            form.save()
            return redirect('/account/profile')
     else:
        form  =  EditProfileForm(instance=request.user)
     args = {'form' : form}
     return render(request,'accounts/edit_profile.html',args)

Answer 2

Вы не вошли в систему и пытаетесь изменить профиль. Чтобы избежать такого рода ошибок, добавьте проверку is_authenticated. Если пользователь не аутентифицирован, вы можете перенаправить его на страницу login с помощью функции быстрого вызова redirect:

def edit_profile(request):
  if request.user.is_authenticated:  
     if request.method=="POST":
        form = EditProfileForm(request.POST,instance=request.user)
        if form.is_valid():
            form.save()
            return redirect('/account/profile')
     else:
        form  =  EditProfileForm(instance=request.user)
        args = {'form' : form}
        return render(request,'accounts/edit_profile.html',args) 
  else:
     return redirect('/login/')
