Django Template - Value Iteration
I am using following code to calculate total price for each item in shopping cart. How should I calculate grand total for whole cart - sum of each "total" from code below?

How to manage multiple device login with django rest framework?
So I have an app in which I previously managed login logout with access tokens. When login, an access token will be generated and it will be sent to FE. Access token will be stored in FE (Front end) and it will define if the user is logged in or not. When the user logs out, access token will be deleted from both FE and BE (Back-end database). In this scenario, logging in with the same account in multiple devices is not possible and also had other issues. Now I want to add multiple device login and some other features. So far I have thought of providing a maintaining a refresh token and access token in the database. The expiration of access token and refresh token will be around 5 minutes and 1 month respectively. When access token will expire during user is logged in, it will check if the refresh token is valid and if valid, new access token will be generated. Access token and refresh token both will remain after logging out to allow multiple device login. But I am not satisfied with this idea and I think there are some best practices and tools that I can … -
Use django models in an external .py file
I am trying to make a telegram bot that needs access to a database of a django app. I want to avoid making webservices in views.py to manage content because I don't want to make an API an just want to keep things separated by the moment, so I need to access to the django ORM in the telegram bot. I have imported the models in my bot main file but I get this message: File "C:\Python37-32\lib\site-packages\django\apps\registry.py", line 135, in check_apps_ready raise AppRegistryNotReady("Apps aren't loaded yet.") django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. Once I get this message, I add the app to settings adding this line to the INSTALLED_APPS variable: 'localadmin.apps.BotConfig' and the next lines in the apps.py file: class BotConfig(AppConfig): name = 'localadmin.bot' Having in mind that there's a folder called "bot" which have the main.py file that launches the bot. So, I think, everything was in order, but, with this changes, I get the next error message. File "C:\Python37-32\lib\site-packages\django\apps\registry.py", line 135, in check_apps_ready raise AppRegistryNotReady("Apps aren't loaded yet.") django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. So I guess my problem, is that I need to use a proper django app to use the models, but I can't do this, due that … -
Twilio with Django - Capturing Call SID
I am trying to implement Twilio with Django. I have followed and implemented this tutorial and it works fine. I've then rolled this into my project and calls work fine.

Django/Docker-compose: Retry Database Connection when: django.db.utils.OperationalError: (2002, "Can't connect to MySQL server on 'db' (115)")
This question have been asked here: django.db.utils.OperationalError: (2002, "Can't connect to MySQL server on 'db' (115)") and the answer has been to wait for the database to be ready. However, the official documentation here: https://docs.docker.com/compose/startup-order/ suggests that instead an in app retry method is implemented in order to retry the database connection when this fails. To handle this, design your application to attempt to re-establish a connection to the database after a failure. If the application retries the connection, it can eventually connect to the database. The best solution is to perform this check in your application code, both at startup and whenever a connection is lost for any reason. Unfortunately, the documentation just ends there and does not provide any examples or guides on how to implement this retry method. Does anyone knows how to do that in a clean way? -

root domain running wordpress and django application on app subdomain - proxy pages from app subdomain to main domain
I have a Saas website that is developed using Django and the marketing site is also hand coded and running under django. I would like to move the marketing site on the main domain to wordpress and then host the web application under an app subdomain. However a number of pages that are important to our SEO are generated by the web application and appear on the main domain now. eg. example.com/service_page_1 example.com/service_page_2 Once I move the application to a subdomain these will be available at: app.example.com/service_page_1 app.example.com/service_page_2 Is there a way example.com can be running a wordpress marketing site and these pages from the subdomain can be made available on the main domain? I thought about hosting the content in iframes on the wordpress site but I am not sure how this would affect SEO. The web application will be running behind an nginx web server. Is there a way to proxy calls to certain routes on wordpress to my web application running behind nginx? (eg. www.example.com/service/*/ to display the page from my web application at app.example.com/service/*/) -

Is there a way to change the display value in series using highcharts

So I am currently working with displaying time and dates in highcharts when I noticed a small problem. When looking at the chart everything looks fine like this. https://i.stack.imgur.com/6hALh.png But when I hover my mouse about a point on the chart it shows a different value. It looks like this https://i.stack.imgur.com/WUr2p.png I would like so that when focusing on a point it will display as HH:MM:SS like it does on the side instead of the total amount of microseconds.
