12. Setting up the Django development environment

Página 57

Chapter 12 of our e-book course covers setting up the Django development environment. Django is a top-notch web development framework, written in Python, that promotes rapid development, clean design, and a pragmatic approach. In this chapter, we'll take you step-by-step through setting up the Django development environment.

1. Python Installation

The first step in setting up the Django development environment is to install Python. Django is written in Python, so you'll need to have Python installed on your computer. You can check if Python is already installed on your computer by opening the terminal and typing 'python --version'. If Python is installed, this command will show the Python version. If not, you'll need to install it.

2. Django Installation

After installing Python, the next step is to install Django. To install Django, you can use pip, which is Python's package manager. Open the terminal and type 'pip install django'. This command will install the latest stable version of Django.

3. Virtual environment configuration

It is good practice to create a virtual environment for your Django project. A virtual environment is an isolated environment where you can install packages without affecting other projects. To create a virtual environment, you can use venv, which is a Python module for creating virtual environments. In the terminal, type 'python -m venv myenv' to create a virtual environment called myenv.

4. Activation of the virtual environment

After creating the virtual environment, you need to activate it. Enabling the virtual environment will ensure that the packages you install will be installed in the virtual environment and not the global system. To activate the virtual environment, in the terminal, type 'source myenv/bin/activate'.

5. Creating the Django project

With the virtual environment turned on, you can create a new Django project. To create a new Django project, in the terminal, type 'django-admin startproject myproject'. This command will create a new Django project called myproject.

6. Running the Django development server

After creating the Django project, you can run the Django development server. The Django development server is a lightweight web server that you can use to develop your project. To run the Django development server, in the terminal navigate to your project directory and type 'python manage.py runserver'. This command will start the Django development server.

7. Creating a Django Application

A Django project is made up of several applications. A Django application is a module that provides specific functionality. To create a new Django application, in the terminal, type 'python manage.py startapp myapp'. This command will create a new Django application called myapp.

8. Database Configuration

Django comes with an abstract database system that lets you work with different database systems. To configure the database, you need to modify your project's settings.py file. In this file, you can define the database system you want to use, the database name, user, password, host and port.

9. Creating the Data Model

With the database set up, you can create the data model. The data model is a representation of the database in Python code. To create the data model, you need to modify your application's models.py file.

10. Database Migration

After creating the data model, you need to migrate the database. Database migration is the process of applying the changes you've made to the data model to the database. To migrate the database, in the terminal type 'python manage.py makemigrations' and then 'python manage.py migrate'.

11. Creation of the view

With the data model and database configured, you can create the view. The view is the HTML representation of the data model. To create the view, you need to modify your application's views.py file.

12. Template creation

The last step in setting up the Django development environment is to create the template. The template is the HTML file that the view uses to generate the web page. To create the template, you need to create an HTML file in your application's templates directory.

We hope this chapter has given you a clear understanding of how to set up the Django development environment. In the next chapter, we'll start developing our Django application.
