  • Create a JSON Response in Python

    JSON (JavaScript Object Notation) file is a very popular medium to interchange data between different formats. It contains data in text format that is supported by various languages such as Python, PHP, PERL, etc. The main purpose of the JSON file is to transfer data between the server and the client. The requests are generated by Python to retrieve the data from a particular resource URI. If the response of the request is returned in JSON format then the content of the response can be retrieved using the response.json() function. It returns the response by using a Python dictionary object. How this function can be used to parse JSON response using the Python request library will be shown in this tutorial.

  • Use of Django Request and Response Objects – Linux Hint

    The Request-response cycle is used to transfer the data between the client and server in all types of web APIs. The client-server architecture is used in the Django framework to implement the web application. The request and response are the two main components of the client-server application. An HttpRequest object is created in the Django application when a client requests any resource. A particular view function is used to handle the request and send the response using the HttpResponse object. The uses of different attributes and methods of HttpRequest and HttpResponse classes of the Django framework will be explained in this tutorial.

  • Form Validation in Django – Linux Hint

    Form validation is a very important task for any web application to enter valid data in the database. The users of the application will not be able to insert invalid data if the form data are validated before submitting. Django is called MVT (Model View Template) based framework where the task of the controller is done by this framework itself. The database-related tasks are done by Model and the data are presented to the template using View. The fields of a form are generated based on the particular model that will insert data into the Django database after validation. One type of validation is done by the browser-based on the field type that is defined in the model. Using the is_valid() function is another way to check the form data whether they are valid or not after submitting the form. This tutorial will show you how the data can be inserted into the Django database after validating the form.

  • How to Build a Basic Search for a Django Site? – Linux Hint

    A particular content of any site is normally retrieved by the users through Google search. However, if this search option is implemented on the website, then the users can easily find their desired content within the site without using Google search. . Another benefit of adding a search option within a website is that the developer can manage the searching output properly. That means he can control which content of the site will appear or not. This tutorial will show the process of implementing the basic search in the Django site.

  • 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.
