Fyyur

Introduction

Fyyur is a musical venue and artist booking site that facilitates the discovery and bookings of shows between local performing artists and venues. This site lets you list new artists and venues, discover them, and list shows with artists as a venue owner.

This project was done as a part of Udacity Full Stack Development Nanodegree.

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

Highlight folders:

• templates/pages -- Defines the pages that are rendered to the site. These templates render views based on data passed into the template’s view, in the controllers defined in app.py. These pages successfully represent the data to the user.
• templates/layouts -- Defines the layout that a page can be contained in to define footer and header code for a given page.
• templates/forms -- Defines the forms used to create new artists, shows, and venues.
• app.py -- Defines routes that match the user’s URL, and controllers which handle data and renders views to the user.
• Models in app.py -- Defines the data models that set up the database tables.
• config.py -- Stores configuration variables and instructions, separate from the main application code.

Data Handling with Flask-WTF Forms

The code uses 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'].

Development Setup

1. Download the project starter code locally

git clone https://github.com/nour-massri/Fyyur.git

2. Create an empty repository in your Github account online. To change the remote repository path in your local repository, use the commands below:

git remote -v
git remote remove origin
git remote add origin <https://github.com/<USERNAME>/<REPO_NAME>.git>
git branch -M master

Once you have finished editing your code, you can push the local repository to your Github account using the following commands.

git add . --all
git commit -m "your comment"
git push -u origin master

3. Initialize and activate a virtualenv using:

python -m virtualenv env
source env/bin/activate

Note - In Windows, the env does not have a bin directory. Therefore, you'd use the analogous command shown below:

source env/Scripts/activate

4. Install the dependencies:

pip install -r requirements.txt

5. Run the development server:

export FLASK_APP=myapp
export FLASK_ENV=development # enables debug mode
python3 app.py
