是否可以在django中使用authenticate方法，只有一个参数作为电子邮件？

Question

如上所述，我想使用django＆＃34; authenticate＆＃34;使用一个参数作为电子邮件的方法因为我使用mastodon api来验证用户并且我已经从mastodon获得了访问令牌。在此之后，我只想在任何django方法的帮助下检查django用户表中是否存在该电子邮件。我使用了authenticate方法，但在密码重置的用例中失败了。 django中是否有任何方法只能通过电子邮件对用户进行身份验证。我在下面提到我的代码，如果代码中的任何修改使得代码运行会很明显。

Django代码：

        mastodon_var = mastodon.Mastodon(

            client_id='gnowsys_ndf/ndf/NROER-client_cred.secret',
            api_base_url='https://member.metastudio.org'
        )

        access_token = None
        ####GET ACCESS FROM MASTODON HERE#######
        try:
            access_token  = mastodon_var.log_in(
            Username,
            Password,
            to_file='gnowsys_ndf/ndf/NROER-access_token.secret',

            )
        except Exception as e:
            print e
            pass        

        name = Username
        email = Username 
        password = Password
        # userna = mastodon_var.u"username"
        # print userna


        #######IF USER GETS ACCESS TOKEN THEN FOLLOWING CODE WILL BE EXECUTED##########
        if access_token:
            if User.objects.filter(username=name).exists():
                ####SECOND AND BY-DEFAULT LAYER FOR AUTHENTICATION
                user = authenticate(username=name,password=password)
                if user is not None:
                    if user.is_active:
                        login(request, user)
                        return HttpResponseRedirect( reverse('landing_page') )
                    else:
                        HttpResponse("Error1")
                return HttpResponseRedirect( reverse('landing_page') )
            else:
                member = User.objects.create_user(name,email,password)
                member.save()


                ####SECOND AND BY-DEFAULT LAYER FOR AUTHENTICATION
                user = authenticate(username=name, password=password)
                if user is not None:
                    if user.is_active:
                        login(request, user)
                        return HttpResponseRedirect( reverse('landing_page') )
                    else:
                        HttpResponse("Error2")
            return HttpResponseRedirect( reverse('landing_page') )   

        else:
            #t = TemplateResponse(request, 'login_template', {})
            #return t.render()
            return HttpResponse("OOps!!!!! You entered wrong credentials")
        #return HttpResponseRedirect( reverse('landing_page') )
    else:

        return HttpResponse("Invalid Credentials.")
