  • How to Use bulk_create() in Django? – Linux Hint

    Django framework can be used to create a web application with a database by writing script in models.py and views.py files of the Django app. The data can be inserted into the database tables by using Django Administration Dashboard or by writing a script in the views.py file. Django Administration Dashboard requires a login for an authenticated user to access the tables of the database. Single or multiple records can be inserted into the database tables by writing a script. bulk_create() method is one of the ways to insert multiple records in the database table. How the bulk_create() method is used to insert the multiple data in a Django database table will be shown in this tutorial.

  • How to Use Django Channel – Linux Hint

    Django is a popular Python framework used to develop web apps using the WGSI (Web Server Gateway Interface) and ASGI (Asynchronous Server Gateway Interface) server specifications. WGSI is used for developing synchronous Python apps, and AGSI is used for developing asynchronous and synchronous web apps. Channel is a useful feature of Django that is used to handle WebSocket, chat protocol, etc. alongside the HTTP protocol. Channel is built on the ASGI server specifications. A two-way interactive communication session between the user’s browser and the server can be opened using a WebSocket. The client initiates the WebSocket connection and the server responds with an accept or close message. The WebSocket messages are pushed into the channel using producers and sent to the consumers that are listening on the channel. This tutorial shows you how to use channels to handle WebSocket messages.

  • Python range() Explained: What It Is and How to Use It - Make Tech Easier

    One aspect of programming that many tutorials don’t tell you upfront is the amount of looping and counting you’ll have to do. As such, any programming language worth its salt will offer ways to enumerate numbers in a repeated way. The Python range sequence type is one of those methods.

  • Monthly Report - February

    Apology for the delay in monthly report, usually I get it released on first day of the month.

    Last month was the shortest month of the year as you all know, so getting things done became relatively harder.

    What is in store this time?

    Well, there were two things that took away all the attentions.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
