For protecting data in views from anonymous users you need to use authenticating system. Django provides built-in functions for auth implementation (documentation).

What is authentication? Authentication - process of user identification data comparison. Authentication passes in two steps:

- User identification - searching in database entered username.

- Authentication. If username from first step exists, system comparing value from "password" field in HTML page with password, saved in database. Be…

Why exactly Docker compose? Docker compose used when you want to run your applications on any machine and start it by one click. This way called as serverless and cross platform architecture. Docker allow you to run applications on any computer, where it installed. It's very convenient and simple.

Django SECRET_KEY need for providing cryptographic signing (documentation). This value is stored in <your_app>/settings.py file. When you start new project it will be generated from built-in function (source code). For production deployment SECRET_KEY must be strong and reliably protected.

These steps help you for generating new SECRET_KEY value:

1. Activate your project's virtual environment:

source env/bin/activate

2. Enter in Django's manage.py shell:

python3 manage.py shell

3. Import get_random_s…

Telegram provides a powerful and simple API for interacting with users via bots. Whether you are building a notification system for your server, a feedback bot, or simply automating daily tasks, the Telegram Bot API is an excellent choice.

You can interact with the API using standard HTTP methods (GET and POST) from any programming language. In this tutorial, we will focus on Python and the requests library to send text messages and files.

Since we will b…

Hardcoding tokens, database credentials and other sensitive data in .py files is not secure. Many people use django-environ library, but I think it inconvenient. So I use yaml files for storing sensitive data and pyyaml library for reading data of them.

Create project folder:

mkdir myproject

cd myproject

python3 -m venv env

source env/bin/activate

pip3 install django pyyaml

Introduction

In my previous article, I covered the absolute basics of downloading and running containers. However, once you start working with Docker daily-especially with stacks like Django and PostgreSQL-you need more tools in your belt.

This cheat sheet covers the essential commands I use for debugging running containers, cleaning up disk space, managing networks, and manually transferring images between servers.

Container lifecycle

While run creates a new c…

If you've worked with Python's requests library to make HTTPS calls, you've almost certainly run into this wall of yellow text in your console:

This warning is common, frequently Googled, and often "f…

After we're figured out the setup cron jobs in operating system, it's time to learn how to run any scripts in Docker container.

Create folder with your project's name and create there four text files with following names:

myproject/
  - my_script.py
  - cronjob
  - Dockerfile
  - docker-compose.yaml

import requests
r = requests.get(url='https://example.com/')
if r.status_code == 200:
    # do something
else:

Допустим тебе надоело работать кассиром в Макдоналдсе, и ты решил ворваться в сферу информационных технологий «с ноги».

Что для этого нужно:
- Усидчивость;
- Терпение;
- Умение пользоваться «Гуглом»;
- Убрать в сторону всякие «не хочу», «не буду».

Что нужно изучать? Все советуют выбрать направление и начинать учиться по нему. Я же скажу что, независимо от выбранного направления, ты должен изучить «базу». Иначе ты становишься хирургом, не знающим анатомию! Не важно, будешь ты инженером по аппаратному …
