How do I use Jinja2 template in my Sendgrid Transactional Template
Is there a way to include jinja2 templating in Sendgrid template? Am trying to use {% for %} and {% endfor %} in Sendgrid template but it doesn't seem to work. Though email sends successfully but its empty when you open it.

How can I store and retrieve Django session variable to/from database?
I have my Django website which is currently being served from two machines, using a load balancer. I want to maintain session correponding to a user from one single machine. I know that I can configure my load balancer to use sticky sessions so that all the requests from a user will be served by the same server. But I want to use session variable to achieve the same. That is how can I store that session variable in a centralised database from which any server can access the session of that user and therefore any server can serve it by using that session variable storage. But I am unable to understand the flow and how will I achieve the same in Django. So my question is how can the session be saved in database for a user, for any server to be able to access it and serve the request accordingly. How will those login() and logout work in this case? -
Load static files for all templates and django (needs update for Django 3.0)
As of django 3.0, they took away the feature that allowed you to not have to put {% load static %} at the beginning of every template. Here's a question & answer that was asked and worked on previous versions: Load static files for all templates in django You could previously just add 'builtins': ['django.contrib.staticfiles.templatetags.staticfiles'] into your template options, and so long as you had {% load static %} in your base.html file, you wouldn't have to add it to any others. Is there another way to not have to add {% load static %} above every template using Django 3.0? -
How to fix "Truncated or oversized response headers received from daemon process" when running a Django application?
I have a Django application that is running on an Apache web server. However, the application throws of the error (found in the error log): Timeout when reading response headers from daemon process 'djangoproject': [Sat Dec 14 06:53:16.317958 2019] [wsgi:error] ... Truncated or oversized response headers received from daemon process My application works but it's turning out to be really slow. This happens very often - especially when I keep refreshing my template. I tried looking into the error and expanding the header limit size in the Apache config file but it didn't resolve my issue. This is my Apache config file: Alias /static /var/myproject/myapp/static <Directory /var/myproject/myapp/static> Require all granted </Directory> Alias /media /var/myproject/myapp/media <Directory /var/myproject/myapp/media> Require all granted </Directory> <Directory /var/myproject/myapp/myapp> #wsgi file lives inside here <Files wsgi.py> Require all granted <Files> </Directory> WSGIScriptAlias / /var/myproject/myapp/myapp/wsgi.py WSGIDaemonProcess djangoproject python-path=/var/myproject/myapp python-home=/var/myproject/myapp/venv WSGIProcessGroup djangoproject Does anyone know how to solve this problem? -

A couple of questions about Django
I just got started with Django and I would like to ask the more experienced devs some questions about. One of the main reasons why I chose to swap to Django is the rest-framework API. Would you say that is good practice to use djoser to take care of auth/register/forgotten passwords and all other features that the library provide or should I code everything by myself? If I want to some columns to the user model such as country, location, phone or others would you recommend me to override the default model or create a new model with a one to one relationship linked to the user? Considering both cases from the question above, will I have to override the registration/update methods or is it gonna sort it out by itself? -

Python - Add custom user models in Django admin
I'm working on a project using Python(3.7) and Django(2.2) in which I have implemented my models for multiple user types with custom user model as the base model. Everything working fine except the admin side, I have register these modles to admin but when I try to add an object from admin interface it's giving an error.

Django session deletion effects another django application
I have two applications running on the same server with different ports and with their SQLite DB's are also different which is used to store user sessions data. if request.session.exists(stored_session_key) and stored_session_key != request.session.session_key: Session.objects.get(session_key=stored_session_key).delete() request.user.logged_in_user.session_key = request.session.session_key request.user.logged_in_user.save() I'm using this condition, to delete the previous session of the same user to logout from previous device and keep login in the current device. This was working as expected. But I have two projects with the same logic. Problem: When I open two applications on the same browser(eg: In chrome, tab-1:https://ip_address:8000, tab-2:https://ip_adress:8001), I can able to login into one application at once. When I tried to login application two, the application one is getting logged out. Why this behavior and how to solve it? My assumption: Browser is sending different session_key, to the same running application when I log-in to a new application? -
Remotely manage the number of objects in a model
Let's say I have a model called Players. I want to limit the amount of players to 20 in one of my Django servers. I also have another, main control panel Django server that would manage all my other Django servers. Before I begin with my problem, here's the Django app I'll be using (Thinking of using, let me know if there's a better option out there) [Django Limits][1] . I want to make it so that my Django Projects would ask my main Control Panel for how many Players to allow for this app. I've set up the rest API and everything on the control panel and it has all the models and stuff, but how would I go on about with the Players Django Project itself to make it ask for how many Players to allow? I can't wrap my head around that. Any help would be appreciated. Thank you for taking your time reading, [1]: https://pypi.org/project/django-limits/ "Django Limits" . -

Django: Problem with Adding Editing and Deleting Functionality in Django Form
I am learning Django by building an application, called TravelBuddies. It will allow travelers to plan their trip and keep associated travel items (such as bookings, tickets, copy of passport, insurance information, etc), as well as create alerts for daily activities. The application will also able to update local information such as weather or daily news to the traveler. Travelers can also share the travel information with someone or have someone to collaborate with them to plan for the trip. I have created a form that enables the users to add their trip information, like trip name, planner name, co-planner, date etc. However, I can't find a proper way of allowing them to edit and delete the forms. I have seen some videos. But they are not using TemplateView like me. So, I am a bit confused. Here are my codes in forms.py file under addtrip folder: from django import forms from django.contrib.auth.models import User from django.forms import ModelForm from trips.models import Trip class TripForm(ModelForm): class Meta: model = Trip fields = ['trip_name', 'date', 'planner_name', 'add_coplanner', 'trip_description'] class UserForm(forms.ModelForm): password = forms.CharField(widget=forms.PasswordInput) class Meta: model = User fields = ['username', 'email', 'password'] Here are my codes in views.py file under … -

Is Django REST framework suppose to be public?
I recently found some security holes in my university website. Among other issues was that, a page for viewing and managing api requests, using Django REST framework was found to be public. There were option to generate manage oauth tokens, and different things like that. I am planning to report the issues together soon. Is this actually a bug or is it suppose to be public? If it is a bug, what are the possible consequences? Is it to be taken seriously? -
