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.

You could be able to use your SQLite code to work with MySQL with the URI mapped as in above code. config = purpose of using ORM like SQLAlchemy is that you can use a different database with limited or no change in most cases. When you install it using pip install pymysql, the SQLALCHEMY_DATABASE_URI will be changing to: app. So I had opted for the MySQL driver with full python implementation pymysql. It was found that the default driver used by the SQLAlchemy ( mqsqldb), didn't get compiled for me in the virtual environment. Else remove it.ĭb.mit() # This is needed to write the changes to database In case your server is not running in the same machine, Put the server IP in place of the localhost.īelow is your code with some little changes: from flask import FlaskĪpp.config = SQLAlchemy(app)ĭb.create_all() # In case user table doesn't exists already. My assumptions are your MySQL server is running on the same machine where Flask is also running and the database name is db_name. Would work without any of the changes rather than a proper modification to the database URI, though the examples I had found for using the SQLAlchemy with the MySQL appear to be using a totally different API.Ĭan I (2) migrate my Flask SQLAlchemy code to work with the MySQL database by just modifying the database URI and if so (1) what should be that URI? Username = db.Column(db.String( 80), unique= True)Įmail = db.Column(db.String( 120), unique= True)ĭef _repr_( self): return '' % ernameĪdmin = User( 'admin', ' ') But I am really worried about (2), I had assumed that SQLAlchemy provided an abstraction layer so that simple SQLAlchemy code such as from flask import Flaskįrom import SQLAlchemyĪpp.config = 'sqlite:////tmp/test.db'Ĭlass User( db.Model): id = db.Column(db.Integer, primary_key= True) I presume that (1) is moderately simple and just a matter of being shown how to map, for example, the contents of the connection dialogue I use in my MySQL database tool to an appropriately formatted URL.

I'm unclear if any of my existing SQLAlchemy SQLite code will work with the MySQL.

I Cannot find out how to connect to the MySQL database (that is, what the SQLALCHEMY_DATABASE_URI should be) and.

I had migrated the database itself and have it running under MySQL, but I had built a site with Flask SQLAlchemy and SQLite and want to switch to MySQL.
