How to create custom login decorators in django
I am creating an app in django where all the authentication like login signup is done by using an exernal rest api so there is no database involved in it. This is why I am saving logged in user data in request.session now the issue is I don't want to show some of the pages if the user is not inside the sessions, what we usually do back in django apps is use @login_required decorator but now as there is no database so what will be the procedure of not showing those pages to not logged in users. thanks -

Django user permission on generate specific view depending on user group
I am new to Django user permission and is setting it up for the first time. I need to generate different views after user has logged in.

Say we have two users called user1 and user2 user1 belongs to group1 user2 belongs to group1 and group2 For user1 I will like to render a view that is specific for group1. For user2 the view rendered must be have both the content specific for group1 and group2 In my current views.py I am only able to decide if a user has logged in and if true the page staffLoginIndex.html will be rendered. from django.shortcuts import render from django.views import View from django.contrib.auth.mixins import LoginRequiredMixin # Create your views here. class StaffLoginIndexView(LoginRequiredMixin, View): login_url = '/accounts/login/' def get(self, request, *args, **kwargs): context = dict() context['user'] = request.user return render(request, template_name='staff/staffLoginIndex.html', context=context) -

How to integrate django with existing Postgres database
To use an existing database in Django, you need to have a model for each table. But creating models for existing tables manually is just too much work. However, there's no need to do that, since Django has a builtin tool to solve this exact problem. Reference article linked here: how-to-integrate-django-with-existing-database -
Custom error message not being raised during model validation
I have created a custom max_length error message on my Question model title field.

csv reader opening files differently in Django and Apache
I need to parse a csv file inside my Django application. The csv file could have some non-ascii characters that I need to remove before processing. Here's what my code looks like with open(inputFile, newline='') as f: reader = csv.reader(f) row1 = next(reader) for element in row1: columnHeader = element.encode("ascii","ignore").decode("ascii").strip() It works perfectly fine in Django standalone. But I get "'ascii' codec can't decode byte 0xef in position 0: ordinal not in range(128)" when I run it in production (Apache, mod_wsgi, Django). I have tried a slightly different formulation, but no luck. columnHeader = element.encode("ascii","ignore").decode() I am new to Apache, Django and Python - so kind of running out of ideas. (Both environments are on the same machine - Ubuntu). -

Redis on Heroku not recognizing Django celery migrations
I have a basic Django app deployed on Heroku with a Redis addon and postgres addon, and my tasks are running fine locally. However, on the deployed app, the worker is not recognizing the celery tables/migrations. I've checked that all migrations have been run on the deployed app (heroku run python3 ./manage.py showmigrations -a {my-app}). My Procfile command: celery -A my_app worker --beat -S django -l info Running this command locally works fine and correctly receives the tasks. I have the DATABASE_URL env variable on heroku set from the postgres addon, and additionally I have added POSTGRES_USER, POSTGRES_DB, and POSTGRES_PASSWORD env variables for the same postgres database.

Bokeh: Generate graph server side, update graph from JS client side (change data source, axes ...)
I just took Bokeh for a spin on a Django site. Lot of fine tutorials out there and really easy to get a quick example running. For example, I have a Django view that offers something like: ... # This is part of a broader Django view, simply adding a graph to it. # Fetch the x and y data for a histogram using a custom function. # It takes a queryset, a field in that queryset and returns, two lists one # containing the unique values that some field took on and the second containing # the count of times it took on that value.

Positioning Django objects, with template for loop tags *Struggling to replicate Instagram push and pop of photo location *
I am having difficulty positioning the photo location after a user posts a photo, where the (Purple Gameboy Photo) goes where the (Mansion Photo) is, and where the (American Football Player Photo) goes where the (Purple Gameboy Photo) is, just like Instagram's profile. Where the most recent go to the top left of the photos, and the last posted photos get pushed down to the bottom right The function checks the first iteration of the for loop and creates a row and column for the first photo, the American Football Player Phot is the first photo posted, then moves along until the fourth photo comes in. Rather than poping the oldest photo to a new row and pushing the newest photo to the front of the existing row. It keeps the location of the first photo and creates a new row for the latest photo.

I am trying to convert a function based view to a class based view....I've done it with the CreateView but the UpdateView is giving me grief. It won't take my update....I can get the view to take my update...but it doesn't save it....I don't get it... Here's my function based view... def update_task_update_view(request, pk): task = Task.objects.get(id=pk) form = TaskForm(request.POST or None, instance=task) if request.method == "POST": if form.is_valid(): form.save() return redirect("MyTasks:task_detail", pk=task.id) context = { "form": form, "task": task } return render(request, "partials/task_form.html", context) And here was my attempt at a Class Based View.... class UpdateTaskUpdateView(LoginRequiredMixin,UpdateView): model = Task form_class = TaskForm template_name = 'partials/task_form.html' def post(self, request, *args, **kwargs): form_class = self.get_form_class() form = self.get_form(form_class) if form.is_valid(): task = form.save() task.save() return redirect("MyTasks:task_detail", pk=task.id) else: return render(request, "partials/task_form.html", { "form":form }) This function based view is working fine...no issues with it. Thanks in advance for any thoughts. -
How to custom save login information in django
I am creating an app where I am dealing with an external REST API, I am sending my login credentials along with JWT token if they are correct I get a success status along with phone number and id, Now I dont know how to save this data to set persmissions to disaplay pages, like in normal app we sigply use login(request, user) to save the user but here we dont have database. Now I want to show some of the pages if the user is authenticated.I tried using reuqest.session['user_id] but deleting the session when user clicks on logout but this does't seems to be a good idea.
