![]() All virtual environments are stored in one folder (which can be overridden through environment variable WORKON_HOME). virtualenvwrapper: A Python package which installs globally and provides a toolset for creating/deleting/activating/etc.Usually, I create the environment close to the project folder. This is my favorite method because it is the simplest way to do the job. virtualenv: A Python package which generates a Python environment folder and has scripts for activating the environment and managing installed Python packages in the environment. ![]() There are a lot of ways to isolate your environment, but the most common ways are: ![]() This mistake is usually made by new Python and Django developers that don’t know about Python’s environment isolation features. This can be a problem if different projects require different incompatible versions of the same package. Python can’t use multiple package versions at the same time. 1: Using the Global System Python Environment for Project Dependenciesĭon’t use Python’s global environment for project dependencies, since it can produce dependency conflicts. As a whole, the Django framework is a pleasant experience and whenever you need help, just read the documentation. Django supports other template engines as well as Django templates, and it provides an API for easy integration of other template engines through standard shortcut functions for templates processing.ĭjango has a lot of other big features like a URL router that can parse incoming requests and build new URLs from a router schema. You can use a lot of standard filters and tags as well as create your new custom filters and tags for your project. It supports all major SQL instructions (and functions) which you can use from your Python source code and feels very comfortable because of Python’s features.ĭjango’s templating engine is very flexible and powerful at the same time. Since it’s lazy, it hits your database only when you need it, unlike other ORMs. With Django admin, you can create one quickly and flexibly.ĭjango has a powerful ORM which works with all major databases out of the box. I believe every application requires an admin panel-if not yet, it’s simply a matter of time until your basic application needs one. Through the Admin interface, a user can configure a lot of things including the access control list (ACL), row-level permissions and actions, filters, orders, widgets, forms, extra URL helpers, and anything else you can imagine. ![]() Django allows you to do all this without compromising on flexibility.ĭjango’s killer feature is a powerful configurable admin interface which builds automatically (automagically?) from your models’ schema and admin panel models, making you feel like a wizard. For me personally, the Admin, Object Relational Mapping tool (ORM), Routing, and Templating features made Django my first choice because applications require a lot of work and, while I enjoy my job as much as any developer could, I want to spend as little time as possible on these basic repetitive tasks. Django has a lot of modern features out of the box. This tutorial is useful even if you’re a skilled Django developer because mistakes, like maintaining an unmanageably large settings or naming conflicts in static assets, aren’t just limited to new developers taking their first stab at Django.ĭjango is a free and open source Python web framework that helpfully solves common development challenges and allows you build flexible, well-structured applications. In this tutorial, we will look at some common mistakes that are often made by Django developers and ways to avoid them.
