Invalid password or unknown hashing algorithm in Django-rest-framework
I created a custom user model making use of just the email and password field. I created the API serializer for the custom user model using the djangorestframework. It seems to send all the data (email and password) but doesn't hash the password. I tried out different solutions here but none seems to work. models.py from django.db import models from django.contrib.auth.models import (BaseUserManager, AbstractBaseUser) class UserManager(BaseUserManager): def create_user(self, email, password=None): # Creates and saves a User with the given email and password if not email: raise ValueError('User must have an email address') user = self.model(email=self.normalize_email(email),) user.set_password(password) user.save(using=self._db) return user def create_staffuser(self, email, password): # Creates and saves a staff User with the given email and password user = self.create_user(email, password=password) user.staff = True user.save(using=self._db) return user def create_superuser(self, email, password): # Creates and saves a superuser with the given email and password user = self.create_user(email, password=password) user.staff = True user.admin = True user.save(using=self._db) return user class User(AbstractBaseUser): email = models.EmailField( verbose_name='email address', max_length=255, unique=True) active = models.BooleanField(default=True) staff = models.BooleanField(default=False) admin = models.BooleanField(default=False) USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] # Email and password are required by default def get_full_name(self): # The user is identified by their email address return self.email … -

rendering a template using ajax in django-oscar
I am trying to customize how the default implementation of Oscar's add review functionality works on a product's detail page, so that instead of django reloading the detail template with the form(default implementation),i use ajax to render the template(with the add review form). Any better way of implementing this to achieve that effect will be appreciated. The default implementation is triggered using a link on the detail page/template like so: {% block content %} ...... <a href="{% url 'catalogue:reviews-add' product_slug=product.slug product_pk=product.id %}#addreview"> </a> ...... {% iffeature 'reviews' %} {% block product_review %} {% endblock product_review %} {% endiffeature %} {% endblock content %} In my implementation I just changed the anchor tag implementation in the detail page/template like so: {% block content %} ...... <a class='xx' product_slug="{{product.slug}}" product_pk="{{ product.id }}" href="#addreview"> </a> ...... {% iffeature 'reviews' %} {% block product_review %} {% endblock product_review %} {% endiffeature %} {% endblock content %} In the default implementation, the product_review form template extends the detail template like so: {% extends "oscar/catalogue/detail.html" %} <div id="addreview" class="review_add" > <form id="add_review_form" method="post" action="#addreview"> ................... </form> </div> The default URLs config for reviews(which lives in the catalogue app as a package) is appended to the catalogue's … -

Unique and custom order_id generated by Django Autofield
I am building an e-commerce solution that stores unique and custom order_id's for every single order. The uniqueness is due to the separation of orders for 1 particular customer. The custom part is for the separation of different suppliers. For example: Supplier name = foo order1: order_id = foo-20202907-001 order2: order_id = foo-20202907-002 ... Supplier name = bar order1: order_id = bar-20202907-001 order2: order_id = bar-20202907-002 ... The first part of the order_is is depending on the name of the supplier. Next it will take in a date stamp and lastly it takes auto incremented field for the order amount that day. My current Order model: class Order(models.Model): order_id = models.AutoField(primary_key=True, editable=False) customer_id = models.ForeignKey(User, on_delete=models.CASCADE) The Autofield starts at 1 and increments it every time a new is placed by 1. When a lot of customers are placing different orders at different suppliers the order_id's get really messy. For the sake of the unique id in my payment system i need something like the above order_id's. I've read some articles about on custom unique field but I don't know whats the right approach. Is there a way to do this? -
Python - retrieving slug value from foreingkey class
I'm a newbie in Python and I need some help with my code. Not even sure if my title makes sense. Basically I have my blog and I'm trying to add a sidebar with popular posts. I have created a PostStatistics class to collect the number of visits in each post which can be seen from Django admin. The PostStatistics class has a ForeignKey to the Post class. OK so my problem is in the PostDetail view. I have a QuerySet there called Popular where I retrieve the 5 most popular posts in the last 7 days. There I retrieve the Post_id and Post__Title. I also need to retrive the Post SLUG but I have no idea how I can do that.

Django activate translations project wide instead of per view?
I have a Django project where I activate the translations based on the Accept-Language header on each and every view as follows, from django.utils import translation translation.activate(request.headers.get('Accept-Language', 'en')) So if I have a ViewSet using Django Rest Framework, I had to do the above for each and every methods as following, class MyViewSet(viewsets.ModelViewSet): def list(self, request, *args, **kwargs): translation.activate(request.headers.get('Accept-Language', 'en')) # .... def retrieve(self, request, *args, **kwargs): translation.activate(request.headers.get('Accept-Language', 'en')) # .... def update(self, request, *args, **kwargs): translation.activate(request.headers.get('Accept-Language', 'en')) # .... def destroy(self, request, *args, **kwargs): translation.activate(request.headers.get('Accept-Language', 'en')) # .... This is just for a viewset, I currently have 10+ viewsets and Translations are needed for every viewset. This make the process even harder to maintain and results in much code duplication. How can I clean up this code to something like activating translations project wide, any options available to do? thank you for any input. -

Does web sockets consume more memory than WSGI app?
I am beginning to explore Django channels (to handle ASGI requests),and created a simple chat app following guide https://channels.readthedocs.io/en/latest/tutorial/part_3.html.

If so I suppose that it will need more processor power to support multiple users. -

Generate same form dynamically pressing a buttom in django
I have modelform called WorkExperienceForm. Currently the form is adding only one information. But work experience can be of multiple times. forms.py: class WorkExperienceForm(forms.ModelForm): """ Creates a form for saving employee work experiences """ class Meta: model = WorkExperience fields = [ 'previous_company_name', 'job_designation', 'from_date', 'to_date', 'job_description', ] widgets = { 'previous_company_name': forms.TextInput(attrs={'class': 'form-control form-control-sm'}), 'job_designation': forms.TextInput(attrs={'class': 'form-control form-control-sm'}), 'from_date': forms.DateInput(attrs={'class': 'form-control form-control-sm has-feedback-left single_cal', 'id': 'single_cal3'}, format='%m/%d/%Y'), 'to_date': forms.DateInput(attrs={'class': 'form-control form-control-sm has-feedback-left single_cal', 'id': 'single_cal4'}, format='%m/%d/%Y'), 'job_description': forms.TextInput(attrs={'class': 'form-control form-control-sm'}), } def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) I want to add a "Add" button to the frontend. When user presses add button, same form will be generated. This can be done unlimited times. I also want to add a delete button so that user can delete form if he/she creates form mistakenly. How can I do that using javascript??? Any help will be appreciated.
