Django dynamic change of LANGUAGE_CODE to use 1 template and 3 translated model fields
I want to use one single template to be displayed in 3 different languages depending on the LANGUAGE_CODE, so I would like to alter the value of LANGUAGE_CODE value and selecting the language from a dropdown menu in my template. My model contains translated fields in 3 languages class Recipe(AuditBaseModel): recipe_id = models.AutoField(primary_key=True) recipe_code = models.CharField(max_length=30, null=False, blank=False) recipe_name = models.TextField(verbose_name=_('recipe_name'), blank=True, null=True) recipe_name_eng = models.TextField(blank=True, null=True) recipe_name_nor = models.TextField(blank=True, null=True) My template is able to show each field depending on the LANGUAGE_CODE {% get_current_language as LANGUAGE_CODE %} {% if LANGUAGE_CODE == 'en-gb' %}<h2>{{ recipe_form.recipe_name_eng.value }}</h2> {% elif LANGUAGE_CODE == 'nb' %}<h2>{{ recipe_form.recipe_name_nor.value }}</h2> {% elif LANGUAGE_CODE == 'es' %}<h2>{{ recipe_form.recipe_name.value }}</h2> {% endif %} Also, in my template, I have a dropdown menu for language selection <li><a href="">Language</a> <ul class="sub-menu"> <li><a href="">English</a></li> <li><a href="">Norsk</a></li> <li><a href="">Espanol</a></li> </ul> </li> How can I dynamically alter the value of LANGUAGE_CODE in my settings.py when the user selects a specific language from the template menu? Any better idea without using i18n? Many thanks in advance -

is it ok to use formview instead of updateview, createview in Django?
so I'm new here in django and have already get the point of some generic views but it really gives me a hard time to understand the UpdateView, CreateView and DeleteView all information that I search still not giving me a point on how to use them. So I have a form registration which have username and password but they are in different table or model to save; you may take a look on the forms.py, And trying UpdateView its giving me only an error to my project. So as I found in some forums, i can't use UpdateView to a foreign key table for its looking only a primary key So instead of using them I use FormView replacing by the 3 generic view for now. Is it ok to use the FormView as an option aside the 3 generic view?

do i need to learn all functions of programming language? [duplicate]
I am new to programming, i know basics of programming. I also write some code in python, php and javascript. Every programming language has hundreds of builtin functions. For example, every programming language has different functions of string, array, int and file I/O etc. Plus framework functions like django, laravel and codeiginter etc. Do i need to learn all builtin functions? for example if i learn php do i need to learn all functions of php plus laravel/codeiginter or if i learn asp.net do i need to learn all functions of c# and asp.net? i don't think it is possible, because there are hundreds of functions in programming language, functions return types and functions parameters? -

Django signals for two types of users
I'm trying to build an app that will have two different user types. Currently I have one type of user called - Tenant Profiles. I'm trying to add in Landlord Profiles type also. Both profiles are derived from Django's in-built auth_users. I have taken last_name field from auth_users to True or False and I'm trying to build Landlord/Tenant profiles based on this condition. I have tried to modify the signals.py file, but have had no luck so far. With code attached below it allows you register, but only creates account for auth_users. If I use commented code in signals.py it will create Tenant Profile. signals.py from django.db.models.signals import post_save from django.contrib.auth.models import User from django.dispatch import receiver from .models import Tenant_Profile, Landlord_Profile # This function aims to create a profile everytime a user registers @receiver(post_save, sender=User) def create_profile(sender, instance, created, **kwargs): #if created: #Tenant_Profile.objects.create(tenant=instance) if created and User.last_name == False: Tenant_Profile.objects.create(tenant=instance) elif created and User.last_name == True: Landlord_Profile.objects.create(landlord=instance) # kwargs just accepts any additional keyword arguments on the end of the function @receiver(post_save, sender=User) def save_profile(sender, instance, **kwargs): #instance.tenant_profile.save() if User.last_name == False: instance.tenant_profile.save() elif User.last_name == True: instance.landlord_profile.save() views.py def register(request): if request.method == 'POST': form = UserRegistrationForm(request.POST) if … -

Django auto primary key field increments instead of taking released ids
I'am using models.AutoField(primary_key=True) for my model, so id field is automatically incremented. Number of rows in a table stays always under 1000, because outdated rows are always deleted, so AutoFiled could use released ids, but it doesn't - it always increments. Can i make it to take free integers from released ids? -

Python: Append a dictionary as a new object to a dictionary key
I am developing a Django API to populate certain sets of data under different sections/categories. In there each section/catergory will have multiple dictionaries. Requirement: "data": { "engineers": { {"id": 1, "name": "aaa"}, {"id": 2, "name": "bbb"}, {"id": 3, "name": "ccc"}, }, "doctors": { {"id": 5, "age": "50"}, {"id": 6, "age": "60"}, {"id": 7, "age": "70"}, }, } In this example I need to append new engineer objects to "engineers" node, and new doctor objects to "doctors" node.

What happens when data on Redis is not consumed?
I just got started with Redis and i'm trying to understand how does it work, so i apologize if what i'm gonna say is not correct. I want to build a real time system where a Python application retrieves stock market trades from around 600 markets. Those trades should be sent to a Django application and shown on the frontend in real time, so i would have Python retrieves the trades > Django receives them and sends them to the page. I did not know how would Django receive the trades, so i thought of making some research on Redis, to see if it would be useful for my case, so here is what i thought: i'm retrieving the trades from 600 markets, so for every market i would create a Redis channel, whenever a trade is received, my Python app will push it to the right Redis channel. On my Django app, whenever an user opens the market page, a connection will be established to the right Redis channel (according to the specifi market that the user requested), and in this way the user will receive the trades on their page. So it would be: Python app updates the … -
How do I hash passwords in DRF?
I have a problem with serialized data that Django REST Framework outputs because the password fields aren't hashed (especially the ones created direct from DRF). The user that I created using createsuperuser command has the serialized password hashed (pbkdf2) which is fine, but the ones that I create using DRF aren't. The serializer that I use looks like this (serializers.py): from users.models import User class UserSerializer(serializers.ModelSerializer): password = serializers.CharField(style={'input_type': 'password'}) class Meta: model = User fields = '__all__' The model class looks like this (models.py): from django.contrib.auth.models import AbstractUser # Create your models here. class User(AbstractUser): class Role: ADMINISTRATOR = 'Administrator' PHARMACIST = 'Pharmacist' PATIENT = 'Patient' choices = { (ADMINISTRATOR, 'Administrator'), (PHARMACIST, 'Pharmacist'), (PATIENT, 'Patient'), } role = models.CharField(max_length=100, choices=Role.choices, default=Role.ADMINISTRATOR) first_name = models.CharField(max_length=100, blank=False) last_name = models.CharField(max_length=100, blank=False) email = models.EmailField(max_length=100, unique=True) birth_date = models.DateField(auto_now_add=False, blank=True, null=True) address = models.CharField(max_length=255) And the queryset looks like this (views.py): from django.shortcuts import render from users.models import User from rest_framework import viewsets from users.serializers import UserSerializer # Create your views here. class UserViewSet(viewsets.ModelViewSet): serializer_class = UserSerializer queryset = User.objects.all() I am looking forward for your help. -
Django 2.2 disabled form field not passed to widget
I'm using the same form for creating and editing an object. One field cannot be edited when editing the object, so I passed it to self.fields['my_field'].disabled = True since django 1.9+ allow that (and it's cleaner). But whatever, the html doesn't change, the input is still editable and there's no disabled attribute on it. Checked in the view's context_data, my context_data['form'].fields['my_field'].disabled is True. So I don't understand what's happening. From what I saw here when the disabled is passed to the widget attributes. Am I missing somehting? When I manually do self.fields['my_field'].widget.attrs['disabled'] it's actually working. Do I have to add it myself to the widget ? Thanks in advance -
Non-pages in Django wagtail menu
I use wagtailmenus for my menus in Wagtail. This works fine for Wagtail pages. But sometime I wan't to include Django apps (e.g. photoalbum etc.) in the menu or submenu. Any ideas how to go about this?
