Forms in Flask

In this Flask app we will demonstrate the basics of processing forms and also using a form library called WT Forms.

Setup

To Run this application, ensure you have installed Python 3 and follow these steps:

1. Clone this repository to your development environment.
2. Change to the directory (e.g. cd flask-forms)
3. Create a virtual environment using python -m venv venv. In some cases you may need to use python3 -m venv venv.
4. Activate the virtual environment using source venv/bin/activate or on Windows use .\venv\Scripts\activate.
5. Run pip install -r requirements.txt
6. Once that is finished, start the built-in development server using flask --debug run.
7. Next, open your web browser and go to http://127.0.0.1:5000/ , you should see the Flask forms webpage displayed.

Note: If you added a .env file and changed the FLASK_RUN_PORT value then you will need to change the port in the URL in step 7.
