Building a basic function calling api using Django

Django tasks, reminders, notifications
I have a fairly simple web app in Django (Apache, Ubuntu) for keeping some meetings documentation. Meetings have their appointment time stored in database (postgres) in datetime format. Now, I'd like to have a custom reminder module that would enable to user to setup their preferred reminders. For example: Meeting will be held at a certain date (let's say 25th of April 2018, 8:00 PM) and user should be able to setup a custom reminder (via SMS for example but the question is not about the sending texts or emails - I got this covered) to be fired up 24h before the time of meeting. It got me thinking that this requires some kind of a permanent process browsing through the meetings table and checking if now() is the appointment time -24h and if yes then perform the reminder. I started with rabbitmq and celery but these look a bit complicated at first glance (here's one of the tutorials I found) and looks like it's not designed for what I need. So, question is - how to setup a permanent process that would check if a set reminder time is now and if yes - perform the reminder task? -
How to use Python script in Django using AJAX or something like that?
Sorry for a badly asked question! I am building an IoT project for schools and colleges written in Django framework. I am using Raspberry Pi in the project and database and web is hosted on DigitalOcean. So, My Raspberry Pi takes care of hardware side, i.e. RFID, Fingerprint, etc and DigitalOcean takes care of admin stuff just for viewing purposes. Now, I have written a script that enrolls students in the database with RFID and Fingerprint and to make purchases in the canteen. It is working without any issues but problem is that there is no GUI to add students or to make purchases. I am using the terminal as of now, which is okay as I can use that stuff but the real operator doesn't know anything about terminal or virtualenv or any of that. So My terminal script is totally useless for them, plus that can expose code. So I have decided to create a web interface for them, where the operator can easily add students and do stuff. I think I can use JSON-AJAX to do that but don't know how. RFID and Fingerprint will return string once successfully scanned, and I need to use those on … -
my nginx cannot load uwsgi on Ubuntu 16.04
trying to run django app "mysite" through uwsgi with nginx on Ubuntu 16.04, but when I start uwsgi and check in my browser, it just hangs. i set django upstream socket to on port 8002 and nginx to listen on 8003. In the browser i visit 192.168.0.17:8003 prior to running uwsgi and it throws 502 which is expected, so I start uwsgi with uwsgi --http :8002 --module mysite.wsgi --logto /tmp/uwsgi.log --master and 8003 now hangs when I reload in the browser. I looked through /var/log/nginx/error.log but it's blank (so is access.log). Here is nginx config, which is symlinked to /etc/nginx/sites-enabled: sudo nano /etc/nginx/sites-available/mysite_nginx.conf # mysite_nginx.conf # the upstream component nginx needs to connect to upstream django { # server unix:///path/to/your/mysite/mysite.sock; # for a file socket server 127.0.0.1:8002; # for a web port socket (we'll use this first) } # configuration of the server server { # the port your site will be served on listen 8003; # the domain name it will serve for server_name 192.168.0.17; # substitute your machine's IP address or FQDN charset utf-8; # max upload size client_max_body_size 75M; # adjust to taste # Django media location /media { alias /home/myusername/uwsgi-tutorial/mysite/media; # your Django project's media files … -
Does django hits the database when you request for an object's attribute from a chached query?
I'm having trouble to understand how to properly use the Caches Framework. lets say I have this code: class Book(models.Model): title = models.CharField() author = models.ForeignKey(User) @classmethod: def get_all_books(cls): query = cache.get_or_set( 'all_books', cls.objects.all() ) return query now I know that every time that I run Book.get_all_books() it returns the already cached result. but what if I run this code in shell: >>> list = listBook.get_all_books() >>> list[0].title # does this line hits the database? >>> list[0].author # does this line hits the database? >>> list.filter(title='for dummies') # does this line hits the database? what did I missed to study? can you please guid me? thank you in advance. -

I am new to django.

How to input query flat output from a different database to a Django model?
First off, I'm new to Django and Python overall - so I might be asking the wrong question, if that's the case please tell me where to look. If not, continue: I'm working with a Django app that queries a Wordpress database, I have created a connection and wrote the query as such: cnxn = MySQLdb.connect(host="localhost", user="root", passwd="password", db="dbname") query = '''SELECT post_id, label, meta_value FROM table''' The issue is that the data is in a flat format, where the label should be the column name and the meta_value should be the value, output: post_id label meta_value ------- ----- ---------- 1 name example name 1 email example@mail.com 2 name example name 2 2 email example2@mail.com Please keep in mind that there are 24 labels for each post_id, so each form entry adds 24 lines to the table. How would I got about creating a Django model that appends the data from the table in a pivot style format to be able to display it nicely in the template? The goal is to be able to display 4-5 labels on the main page with a link on each line that shows the full input on a separate page. Desired output: post_id … -

not much change in queries time when using redis cache
I am learning caching django apps using django-redis. In my home page, there is nothing dynamic. I have used the caching over there. I see not much difference. The following query has taken more time and I don't know what it is for and why SELECT ••• FROM "djconfig_config" WHERE "djconfig_config"."key" = '''_updated_at''' 90.03221908981072% 1.07 The way I have used the caching is CACHE_TTL = getattr(settings, 'CACHE_TTL', DEFAULT_TIMEOUT) @cache_page(CACHE_TTL) def index(request): # if not request.user.is_authenticated(): # return render(request, "index.html") # else: # return render(request, "index.html") return render(request, "index.html") No query is done here instead it's taking that much time due to the query of djconfig_config. However, I have used middleware to check the invitation exist or not in every request to set the session of invite_code and email. Here is the screenshot before and after caching Do I have to do something more? -
pycharm django test custom setting is overridden
I am new to django. When I try to run tests, I encounter the following error: NotImplementedError: Language af is not supported and tests run with no problem on other devices, which means the problem is of my pyCharm. My test configuration is same as the other device. the line which raises the error is: VALID_CHARACTERS = {lang: _get_valid_characters(lang) for lang in LANGUAGE_LIST} where LANGUAGE_LIST = [x[0] for x in settings.LANGUAGES] and settings.LANGUAGES is returning all languages, instead of my language (where af is the first language in list). In my projectcomon/settings.py I have LANGUAGES = [ ('fa', 'Farsi'), ] bu it seems to be overridden by default setting. Where is the problem? thanks -

Pre-Populate template field with default value from model in Django/Wagtail
I want to add a default value and have it populate the field in a Wagtail template based on a Django model.

Django: Context Processors Returning same value for different Users
I have a django app in which users can Answer a Question, I'm having some trouble while printing the number of views different users. Here's my Answer model, class Answer(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, default=1) content = models.TextField() views = models.IntergerField(default=1) Here's how I'm getting the number of views per user inside the context_processors.py, def all_views(request, pk=None): if pk: my_user = User.objects.get(id=pk) else: my_user = request.user user_views = Answer.objects.filter(user=my_user).aggregate(Sum('views')) context = {'user_views': user_views } return context But the problem is that it's returning the number of views of request.user for every single user. Means if I log in as abc (id=1) having 20 views & visit xyz (id=2) profile having 40 views, then it shows 20 views on xyz profile as well instead of 40. Why if pk: condition is not working? & How can we fix that? Thank You! -
