Tech Stack (Dependencies)

1. Backend Dependencies

Our tech stack will include the following:

• virtualenv as a tool to create isolated Python environments
• SQLAlchemy ORM to be our ORM library of choice
• PostgreSQL as our database of choice
• Python3 and Flask as our server language and server framework
• Flask-Migrate for creating and running schema migrations You can download and install the dependencies mentioned above using pip as:

pip install virtualenv
pip install SQLAlchemy
pip install postgres
pip install Flask
pip install Flask-Migrate

Note - If we do not mention the specific version of a package, then the default latest stable package will be installed.

2. Frontend Dependencies

You must have the HTML, CSS, and Javascript with Bootstrap 3 for our website's frontend. Bootstrap can only be installed by Node Package Manager (NPM). Therefore, if not already, download and install the Node.js. Windows users must run the executable as an Administrator, and restart the computer after installation. After successfully installing the Node, verify the installation as shown below.

node -v
npm -v

Install Bootstrap 3 for the website's frontend:

npm init -y
npm install bootstrap@3

Overall:

• Models are located in the MODELS section of app.py.
• Controllers are also located in app.py.
• The web frontend is located in templates/, which builds static assets deployed to the web server at static/.
• Web forms for creating data are located in form.py

Data Handling with Flask-WTF Forms

The starter codes use an interactive form builder library called Flask-WTF. This library provides useful functionality, such as form validation and error handling. You can peruse the Show, Venue, and Artist form builders in forms.py file. The WTForms are instantiated in the app.py file. For example, in the create_shows() function, the Show form is instantiated from the command: form = ShowForm(). To manage the request from Flask-WTF form, each field from the form has a data attribute containing the value from user input. For example, to handle the venue_id data from the Venue form, you can use: show = Show(venue_id=form.venue_id.data), instead of using request.form['venue_id'].
