Py: This is another configuration file. You can think of it as a mapping between the URLs and Python functions that handle them. This file is one of Django's powerful features, and we will see how to utilize it in the next chapter. When we start writing code for our application, we will create new files inside the project's folder; so the folder also serves as a container for our code. Now that you have a general idea of the structure of a Django project, let's configure our database system. Setting up the database In this section, we will start working with setting up the database with various options and configuration files.
Open source: Using code written by someone else has finally become preferable than writing your own code. API as spinal cord: Web technologies today might not be the same tomorrow, or data might not be represented in the same way or in the same place tomorrow. In other words, more devices will come with different screen sizes. User Interface: In the past, the precious time of the development team was consumed by User Interface design. Agile development: Moving fast in the development cycle is acceptable to most startup companies.
