Where to store translations in microservice architectre
For today I have 2 microservice apps. The first one is a backend application built with Django and Django Rest Framework. The second one is the frontend application built with React. I store some info that needs to be translated in the DB. Let's perhaps I have a table named "furniture_types" with only one column the name. And data is 4 rows: "chair", "sofa", "table", "bed". On front-end, I want to display translations for "furniture_types" in other languages for example Russian and Ukrainian. And what I do I store translation files on the frontend and and use intl frameworks. So if user chose Ukrainian he will see "стілець" instead of "chair" and so on. Everything works well know but I see two problems that I still don't mind of solution for. I use django admin and I want to have the admin panel and some tables data in the admin panel be translated into the Russian. What I mean is when the user go to admin panel and want to create an Order in the field furniture type will see the list of options in russian language not as the stored in the DB.

How can i send requests to another service from a Django view?
I'm trying to create a simple microservice structure on my Django project where, when a certain Django view is called, this view will send a JSON post request to a Flask microservice containing some user's data; the Flask microservice should receive the request, take that user's data and send back to Django some additional data using Requests again, so that my Django view can receive that data and perform some operations, such as showing it to the user. Right now i'm just sending some dummy data, to test if this Django > request to Flask > Flask > Request to Django system works, but i'm encountering some problems. To debug my code, right now, i'm trying to just print the received data, but i'm having some troubles.

Passing calculated value to Django template
I'm pretty new to Django and I'm having trouble with passing a variable to a Django template. My code finds the average of an Integer field from the database (using Django's AVG) then perform a calculation on the result. Ultimately I would like to pass the result of this calculation to a template. My model.py is: from django.db import models class Post(models.Model): fname = models.CharField(max_length=20) lname= models.CharField(max_length=25) reading=models.IntegerField(default=100) entrytime=models.DateTimeField(auto_now_add=True) def __str__(self): return self The view is: from django.views.generic import TemplateView, ListView from django.db.models import Avg from .models import Post class ShowCalcView(ListView): model=Post template_name = 'calc.html' def calca1c(request): context = Post.objects.aggregate(Avg('reading')) r=context['reading__avg'] rs = (46.7 + r) / 28.7 context['calc'] = rs return context The template is: <h1>Approximate A1C</h1> <p>Approximate A1c: {{ calc }}</p> I have tried using {{ calc }}, {{ calc.rs}}, {{ calc['rs'] }}, and just about every other combination I can think of but the value is not being passed. I have checked the function in the shell, and it produces the desired result. I'm probably missing something obvious but I cannot figure it out. Thank you for your assistance.
