SECRET_KEY = config("SECRET_KEY", default="guess-me") If DATABASE_URI.startswith("postgres://"):ĭATABASE_URI = DATABASE_URI.replace("postgres://", "postgresql://", 1) Within the file, add the following content: from decouple import config We'll store the configurations for the project in this file. In the root directory of the project (that is, outside the src directory), create a file called config.py. You'll define them later in the tutorial. You've also registered blueprints called accounts_bp and core_bp in the application. To use Flask-Bcrypt, Flask-SQLAlchemy, and Flask-Migrate in your application, you just need to create objects of the Bcrypt, SQLAlchemy and Migrate classes from the flask_bcrypt, flask_sqlalchemy and, flask_migrate libraries, respectively. You also set the configuration of the app using an environment variable called APP_SETTINGS. We use the _name_ argument to indicate the app's module or package so that Flask knows where to find other files such as templates. In the above script, we created a Flask app called app. The first file will be the _init_.py file for the project: from decouple import configĪpp.om_object(config("APP_SETTINGS"))įrom import accounts_bp Let’s start by creating a src directory: mkdir src To install the above-mentioned libraries, run the following command: pip install Flask Flask-Login Flask-Bcrypt Flask-WTF FLask-Migrate Flask-SQLAlchemy Flask-Testing python-decouple This tutorial was verified with Python V3.11, Flask V2.2.2, Flask-Login V0.6.0, Flask-Bcrypt V1.0.1, Flask-WTF V1.0.1, Flask-SQLAlchemy V2.5.1 and, Flask-Testing V0.8.1. Python Decouple helps you use environment variables in your Python project.Flask-Testing extension provides unit testing utilities for Flask.It helps you simplify things using SQLAlchemy with Flask by giving you useful defaults and extra helpers that make it easier to perform common tasks. Flask-SQLAlchemy is an extension for Flask that adds support for SQLAlchemy to your application.The database operations are made available through the Flask command-line interface. Flask-Migrate is an extension that handles SQLAlchemy database migrations for Flask applications using Alembic.Flask-WTF is a simple integration of Flask and WTForms that helps you create forms in Flask.Flask-Bcrypt is a Flask extension that provides bcrypt hashing utilities for your application. It handles the common tasks of logging in, logging out, and remembering your users’ sessions over extended periods of time. Flask-Login provides user session management for Flask.Flask is a simple, easy-to-use microframework for Python that helps you build scalable and secure web applications.To verify if the environment has been activated or not, you can see (env) in your terminal. Now, we need to activate the environment using this command: source env/Scripts/activate The above command will create a virtual environment named env. So, to create a virtual environment, you can use the below command: python -m venv env Python now ships with a pre-installed venv library. We are going to create a virtual environment using venv. Let's learn more about them and install them one by one.īut before we install them, let's create a virtual environment and activate it.įirst, start with creating the project directory and navigating to it like this: mkdir flask-basic-auth You'll need a few external libraries in this project. Basic knowledge of Flask and Flask Blueprints. Prerequisitesīefore you get started with the tutorial, make sure you have the following requirements satisfied: Feel free to check it out whenever you're stuck. return Response(movies, mimetype="application/json", status=200)Īs we can see flask-restful uses a Class-based syntex so, if we want to define a resource (i.The link to the GitHub repository is available at the end of the tutorial. Return Response(movies, mimetype="application/json", methods=) +movies = Blueprint('movies', get_movies(): #~/movie-bag/resources/movie.py +from flask import Blueprint, Response, request
