Django registration 'AnonymousUser' object has no attribute '_meta'
I have created a website where the user will login with his email instead of username as Django does. So, I have created an AUTHENTIFICATION_BACKENDS: class EmailBackend(object): def authenticate(self, username=None, password=None, **kwargs): try: user = User.objects.get(email=username) except User.MultipleObjectsReturned: user = User.objects.filter(email=username).order_by('id').first() except User.DoesNotExist: return None if getattr(user, 'is_active') and user.check_password(password): return user return None def get_user(self, user_id): try: return User.objects.get(pk=user_id) except User.DoesNotExist: return None My form: class UserRegisterForm(forms.ModelForm): username = forms.CharField() email = forms.EmailField() age = forms.IntegerField() password2 = forms.CharField() password = forms.CharField() class Meta: model = User fields = ['username', 'age', 'email', 'password', 'password2'] At this stage, the login with an email is Working perfectly. The problem starts when I try to register a user. In registration view: form = UserRegisterForm(request.POST) register a new user: user = form.save(commit=False) username = form.cleaned_data['username'] password = form.cleaned_data['password'] user.set_password(password) user.save() user = authenticate(username=username, password=password) login(request, user) This is where the problem appears. it seems like user = authenticate(username=username, password=password) is trying to create an anonymous user. What am I doing wrong in my AUTHENTIFICATION_BACKENDS ?? -
Add E-Mail header in django
So I have a code like this in the views.py from django.core.mail import send_mail send_mail( 'subject', 'message.', 'info@xyz1234.de', ['test1234@gmail.com'], fail_silently=False, # headers={'List-Unsubscribe': '<http://www.xyz1234.de/unsubscribe123'}, ) I want to add the header 'List-Unsubscribe' but it doesn't work and I get a server error.

Wagtail - display the three latest posts only on the homepage
I have created a model to show posts on the homepage, but only want the three latest posts to show. Do I need to use pagination for this, or is there a hook I can use instead? I was thinking I could use pagination and just not include the 'next' button, but that seems somewhat like a hack, and I want to do this the right way. I am still very new to Django and Python and am going to continue experimenting, but if someone could point me in the right direction I would be very grateful. Here's the HomePage model: from __future__ import unicode_literals from django.db import models from wagtail.wagtailcore.models import Page from wagtail.wagtailcore.fields import RichTextField from wagtail.wagtailadmin.edit_handlers import FieldPanel from blog.models import BlogPage class HomePage(Page): def blogs(self): blogs = BlogPage.objects.all() blogs = blogs.order_by('-date') return blogs Here's the BlogPage model: class BlogPage(Page): body = RichTextField(verbose_name=_('body'), blank=True) tags = ClusterTaggableManager(through=BlogPageTag, blank=True) date = models.DateField( _("Post date"), default=datetime.datetime.today, help_text=_("This date may be displayed on the blog post. It is not " "used to schedule posts to go live at a later date.") ) header_image = models.ForeignKey( 'wagtailimages.Image', null=True, blank=True, on_delete=models.SET_NULL, related_name='+', verbose_name=_('Header image') ) author = models.ForeignKey( settings.AUTH_USER_MODEL, blank=True, null=True, limit_choices_to=limit_author_choices, … -

Django Automatically call method after data is added DB
After adding data to a certain table in DB through Django admin I want a method to be called automatically to process this data (before or after it was added to DB) and save the output in a different table, so that when user logs in the view doesn't have to wait for processing of that data and only query a table for prepared output. -
Twitter.error.TwitterError: {'message': '"user_id" must be type int'}
I am trying to "python-twitter" in my django project. My code tweet = cache.get('tweet') if not tweet: tweet = twitter.Api().GetUserTimeline( settings.TWITTER_USER )[0] tweet.date = datetime.strptime( tweet.created_at, "%a %b %d %H:%M:%S +0000 %Y" ) cache.set( 'tweet', tweet, settings.TWITTER_TIMEOUT ) But I am getting below error Twitter.error.TwitterError: {'message': '"user_id" must be type int'} I have set the variables to TWITTER_USER = 'CaseyNeistat' TWITTER_TIMEOUT = 3600 as the blog suggested then why the error.

Partial object returned when Serializing a model with relationship
So I have two models Foo and Bar. Foo has a one to many relationship with Bar as shown below. app/models.py class Foo(models.Model): id = models.IntegerField(primary_key=True) sourceid = models.IntegerField(blank=True, null=True) name = models.TextField(unique=True, null=True) url = models.TextField(unique=True, null=True) created_at = models.DateTimeField(default=datetime.datetime.utcnow, null=True) updated_at = models.DateTimeField(default=datetime.datetime.utcnow,null=True) class Meta: managed = False db_table = 'foo' class JSONAPIMeta: resource_name = 'foo' class Bar(models.Model): id = models.IntegerField(primary_key=True) parent_foo = models.ForeignKey(Foo, models.DO_NOTHING, db_column='parentId') # Field name made lowercase. url = models.TextField() extension = models.ForeignKey('self', models.DO_NOTHING, db_column='extensionId', blank=True, null=True) created_at = models.DateTimeField(blank=True, null=True) updated_at = models.DateTimeField(blank=True, null=True) class Meta: managed = False db_table = 'bar' Now the issue is that I want to create a serializer FooBarList that nests Bars into Foo. I have managed to slightly achieve this with the following code: app/serializers.py class FooBarList(serializers.ModelSerializer): class Meta: model = Foo fields = ('id','name','url','created_at','updated_at','bar_set') When I call this serialise function the issue arrises... Only the 'id' parameter of the Bar object is shown in the response. This is shown below: JSON Output { "data": [ { "attributes": { "created_at": "2017-08-23T16:07:11.384209Z", "name": "TestFoo", "updated_at": "2017-08-23T17:41:17.179040Z", "url": "TestFoo.org" }, "id": "1", "relationships": { "Bar": { "data": [ { "id": "1", "type": "Bar" }, { "id": "2", "type": "Bar" … -

How to make Django-Oscar appear as a separate app in Django admin panel?
Good day y'all! Here comes a basic Django question: I was running a Django project with one app in it and installed Django-Oscar to cover my ecommerce needs. So, I pip installed it in my main project and set everything up the way they explain it on readthedocs. Now, the structure of my admin panel looks like this: Main project My app Oscar Address Oscar Analytics Oscar ... And I'd like it to be: Main project My app Shop Oscar Address Oscar Analytics Oscar ... I already did django-admin startapp shop for that matter. Apparently the question is so obvious that I can't find any tutorials for dummies to do this. Can someone point me in the right direction? Maybe a generic tutorial about including apps in apps the right way is laying around somewhere? Thank you in advance. -
How to remove the ?q= from the url in Django
My current url looks like this: [domain name]/?q=[search_term] and would like to make it look like this: [domain name]/[search_term] In my urls.py I have the following code: urlpatterns = patterns('', url(r'^$', 'home', name='home'), url(r'^q=(?P<search_term>[A-Za-z0-9\-]+)$', 'home', name='query'), In views.py the code looks like this: def home(request, search_term='q'): do stuff return render(request, 'template', {context}) For some reason, no matter if I have a search_term in the url or not, the app always serves the first route.
