Question

def sign_in(request):
    #we need to handle all the data that was just typed, we'll add a condition for that
    form = NameForm(request.POST)
    if form.is_valid():
        post = form.save()
        post.save()
        username = request.POST.get('username')
        password = request.POST.get('password')
        #auth = authenticate(username=username, password=password)
        # If the username and password are provided try to auth them
        if username and password:
            print username, password
            user = authenticate(username=username, password=password)
            # if it authenticates successfully, check if the user is not an admin, log them in
            if user:
                if not user.is_staff:
                    login(request,user)
                return HttpResponseRedirect('success')
    else:
        form = NameForm()
    return render(request, 'checkin/sign_in_new.html', {'form': form})

编辑：更改了代码以使用后端。添加了user.is_staff但它仍然不会返回任何网页，它只会停留在同一个网页上

models.py：

from __future__ import unicode_literals

from django.db import models
from django import forms
from django.forms import ModelForm

# Create your models here.

class Question(models.Model):
    question_text = models.CharField("What is your ID?", max_length=100, null=True)
    #pub_date = models.DateTimeField('date published')

    id_text = models.CharField("", max_length=200, null=True)

    def __str__(self):
        return self.question_text

forms.py：

from django.forms import ModelForm
from .models import Question

#put the form here

class NameForm(ModelForm):
    class Meta:
        model = Question
        fields = ['question_text', 'id_text']

class IdForm(ModelForm):
    class Meta:
        model = Question
        fields = ['id_text']

编辑2 这些是我的模型和表单文件，如果它们不影响我后端中某些参数的命名？

Answer 1

我就是这样做的，它有效...但我自动创建用户，所以没有表单输入，但你应该明白这个想法：

            user, created = User.objects.get_or_create(username=user_email, email=user_email)

            if created:
                secret = str(uuid4())
                user.set_password(secret)
                user.save()

            user = User.objects.get(username=user_email)
            user.backend = 'django.contrib.auth.backends.ModelBackend'
            login(request, user)

所以对你来说，你可以使用User.objects.get_or_create ...代替create_user

你显然必须添加auth步骤。

Answer 2

Django身份验证系统。

我认为您熟悉使用模型保存用户数据您可以使用身份验证后端来解决此问题，请参阅以下步骤。创建自定义后端。在项目根目录中后端/ staff_backends.py

from project_app_path.staffs.models import MODEL_NAME
from django.contrib.auth.hashers import check_password
from django.contrib.auth.models import User
class StaffBackend:
    def authenticate(self, username=None, password=None):

        try:
            user = MODEL_NAME.objects.get(username=username)
            if check_password(password, user.password):
                return user
            else:
                return None
        except MODEL_NAME.DoesNotExist:
            return None
    def get_user(self, user_id):
        try:
            return MODEL_NAME.objects.get(pk=user_id)
        except MODEL_NAME.DoesNotExist:
            return None

包含项目设置的后端。

AUTHENTICATION_BACKENDS = [ 

'django.contrib.auth.backends.ModelBackend',
'backends.staff_backends.StaffBackend',

]

在views.py中

from django.contrib.auth import authenticate, login ,logout

def any_view(request):
    rg = request.POST.get
    username = rg('username')
    password = rg('password')
    if username and password:
        print username,password
        user = authenticate(username=username,password=password)
        if user:
            if not user.is_staff:
                login(request,user)
            ### Redirect where you want , you can use this code in to you  signupage also.
