How to implement two different types of users with extended attributes in Django?
I am using python 3.8.3 and Django 3.0.8 I am building a project that allows students and teachers to login to it. Hence I have two different kinds of users. Also these two users have extended attributes and methods apart from the one that Django provides implicitly to its user model, like department, organisation, etc. How can I implement them? Most of the articles I come across are either very old and for outdated versions of Django and python or they don't combine my required functionality? How can I extend my user model to have more attributes and how do I implement two different kinds of users? And how do I separately enforce authentication for these two different kinds of users? -

'Authentication Unsuccessful' When Trying To Send Email Through Django
I've been trying to send emails using my Outlook email through Django but have been getting a variety of error messages, including (535, b'5.7.3 Authentication unsuccessful [SYBPR01CA0102.ausprd01.prod.outlook.com]') Apparently I need to allow SMTP AUTH, but cannot find how to do this as I am using Outlook in my browser and don't have it downloaded (it keeps requesting I pay for it, but I'd prefer not to as I really don't see the need for this small project, unless I need to). I did however pay for the email. I've also read that Outlook doesn't support smpt: Outlook 365 OAuth 535 5.7.3 Authentication unsuccessful My settings in Django are: DEFAULT_FROM_EMAIL = '###@###.###' EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp-mail.outlook.com' EMAIL_PORT = 587 EMAIL_USE_TLS = True EMAIL_HOST_USER = '###@###.###' EMAIL_HOST_PASSWORD = '########' My question is can I send Outlook emails through Django? If so, what am I doing wrong? Thank you. -

(Django) How to create a verification mixin that references two models?
I have two classes Organisation, and Staff in addition to the User class. I want to create a mixin called "UserIsAdminMixin" that checks whether the user logged in has the role "admin" in a specific Organisation. The classes (simplified) class Organisation(models.Model): name = models.CharField(max_length=50) class Staff(models.Model): class Role(models.TextChoices): ADMIN = 'ADMIN', "Admin" STAFF = 'STAFF', "Staff" user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, blank=True, db_index=True, related_name="staff_profiles", on_delete=models.SET_NULL) organisation = models.ForeignKey('organisations.Organisation', db_index=True, related_name="staff", on_delete=models.CASCADE) role = models.CharField(max_length=10, choices=Role.choices, default=Role.STAFF) I then currently have this for my UserIsAdmin mixin: class UserIsAdminMixin: def dispatch(self, request, *args, **kwargs): if self.request.user.staff_profiles.filter(organisation=self.get_object(), role=Staff.Role.ADMIN): return super().dispatch(request, *args, **kwargs) else: raise PermissionDenied This works great for this view: organisations.views.py (URL: organisation/<int:pk>) class OrganisationDetail(LoginRequiredMixin, UserIsAdminMixin, generic.DetailView): model = Organisation template_name= "organisations/detail.html" login_url = "login" But I'd also like it to work for this view as well, which it obviously doesn't as self.get_object() returns a Staff object in this case when it's expecting an Organisation object: staff.views.py (URL: organisation/<int:pk_alt>/staff/<int:pk>) class StaffDetail(LoginRequiredMixin, UserIsAdminMixin, generic.DetailView): model = Staff template_name="staff/detail.html" login_url = "login" I was able to make changes to the mixin to get it to work in the second scenario but not the first: class UserIsAdminMixin: def dispatch(self, request, *args, **kwargs): if self.request.user.staff_profiles.filter(organisation__pk=self.kwargs['pk_alt']), role=Staff.Role.ADMIN): return … -

Class Style not working on Django Template
I'm trying to color the background of readonly input text in my Django templates. I'm being brief in code because the only thing is not working is the color background. I'm using the field 'rua' as the example. Maybe the problem is with the link of 'my own css' inside the base.html. My forms.py: 'rua': forms.TextInput(attrs={'readonly': 'readonly', 'id': 'rua', 'class': 'readonly'}), My template: {% extends "base.html" %} {% load static %} {% block content %} <script src="https://cdn.rawgit.com/igorescobar/jQuery-Mask-Plugin/master/src/jquery.mask.js"></script> <!-- customer login start --> <div class="customer_login"> <div class="container"> <div class="row"> <!--register area start--> <div class="col-lg-6 col-md-6 mx-auto"> <div class="account_form register"> {% if register_edit == 'register' %} <p>{{ msg }}</p> <h2>Não tem conta? Registre-se!</h2> <form method="post" action="{% url 'account:register' %}"> {% else %} <h2>Altere os dados da sua conta</h2> <form method="post" action="{% url 'account:edit' %}"> {% endif %} {% csrf_token %} <div>{{ user_form.as_p }}</div> <div>{{ profile_form.as_p }}</div> <p><button type="submit">Enviar</button></p> </form> </div> </div> <!--register area end--> </div> </div> </div> <!-- customer login end --> <script src="{% static 'js/cadastro.js' %}" type="text/javascript"></script> {% endblock %} My base.html {% load static %} <!doctype html> <html class="no-js" lang="pt-br"> <head> <meta charset="utf-8"> <meta http-equiv="x-ua-compatible" content="ie=edge"> <title>Denise Andrade - Store</title> <meta name="description" content=""> <meta name="viewport" content="width=device-width, initial-scale=1"> <!-- Favicon --> … -

AttributeError at /cart/ 'NoneType' object has no attribute 'price'
I'm working on a e-commerce site, I wanted to change the products that I previously had. I went into the admin site and uploaded the new products you see in the photo. Once I saw everything was working I decided to delete 6 old products through the admin page. I then went to my cart and got this error, I'm confused why I'm getting this error with new products and not my original products site with new products error yellow page def cart(request): # check authenticated user data = cartData(request) cartItems = data['cartItems'] order = data['order'] items = data['items'] context = {'items': items, 'order': order, 'cartItems': cartItems} return render(request, 'store/cart.html', context)
