Open-source dashboard generated by AppSeed in Flask Framework. Atlantis Lite (Dark Design) is a free bootstrap 4 admin dashboard that is beautifully and elegantly designed to display various metrics, numbers or data visualization.


Adding a new Blueprint

This sample shows how to define a new blueprint and use it on top of an existing starter. Steps:

  • Create a new directory for the blueprint with files:
    • init.py - declare the Blueprint
    • routes.py - the routing rules handled by the new Blueprint
  • The route /list-html will serve a simple HTML
<!-- File Contents: <ROOT> / app / home / templates / list-index.html -->
...
<div>
	<h2 class="text-white pb-2 fw-bold">Dashboard - LIST HTML</h2>
	<h5 class="text-white op-7 mb-2">
		<a href="{{ url_for('files_blueprint.list') }}" > ACCESS BP Link </a>
	</h5>
</div>

Manual Build

$ # Get the code
$ git clone https://github.com/app-generator/sample-flask-blueprints.git
$ cd sample-flask-blueprints
$
$ # Virtualenv modules installation (Unix based systems)
$ virtualenv env
$ source env/bin/activate
$
$ # Virtualenv modules installation (Windows based systems)
$ # virtualenv env
$ # .\env\Scripts\activate
$
$ # Install modules - SQLite Database
$ pip3 install -r requirements.txt
$
$ # OR with PostgreSQL connector
$ # pip install -r requirements-pgsql.txt
$
$ # Set the FLASK_APP environment variable
$ (Unix/Mac) export FLASK_APP=run.py
$ (Windows) set FLASK_APP=run.py
$ (Powershell) $env:FLASK_APP = ".\run.py"
$
$ # Set up the DEBUG environment
$ # (Unix/Mac) export FLASK_ENV=development
$ # (Windows) set FLASK_ENV=development
$ # (Powershell) $env:FLASK_ENV = "development"
$
$ # Start the application (development mode)
$ # --host=0.0.0.0 - expose the app on all network interfaces (default 127.0.0.1)
$ # --port=5000    - specify the app port (default 5000)  
$ flask run --host=0.0.0.0 --port=5000
$
$ # Access the dashboard in browser: http://127.0.0.1:5000/

Note: To use the app, please access the registration page and create a new user. After authentication, the app will unlock the private pages.


Codebase Structure

The project is coded using blueprints, app factory pattern, dual configuration profile (development and production) and an intuitive structure presented bellow:

Simplified version

< PROJECT ROOT >
   |
   |-- app/                      # Implements app logic
   |    |-- base/                # Base Blueprint - handles the authentication
   |    |-- home/                # Home Blueprint - serve UI Kit pages
   |    |
   |   __init__.py               # Initialize the app
   |
   |-- requirements.txt          # Development modules - SQLite storage
   |-- requirements-mysql.txt    # Production modules  - Mysql DMBS
   |-- requirements-pqsql.txt    # Production modules  - PostgreSql DMBS
   |
   |-- .env                      # Inject Configuration via Environment
   |-- config.py                 # Set up the app
   |-- run.py                    # Start the app - WSGI gateway
   |
   |-- ************************************************************************

The bootstrap flow

  • run.py loads the .env file
  • Initialize the app using the specified profile: Debug or Production
    • If env.DEBUG is set to True the SQLite storage is used
    • If env.DEBUG is set to False the specified DB driver is used (MySql, PostgreSQL)
  • Call the app factory method create_app defined in app/init.py
  • Redirect the guest users to Login page
  • Unlock the pages served by home blueprint for authenticated users

App / Base Blueprint

The Base blueprint handles the authentication (routes and forms) and assets management. The structure is presented below:

< PROJECT ROOT >
   |
   |-- app/
   |    |-- home/                                # Home Blueprint - serve app pages (private area)
   |    |-- base/                                # Base Blueprint - handles the authentication
   |         |-- static/
   |         |    |-- <css, JS, images>          # CSS files, Javascripts files
   |         |
   |         |-- templates/                      # Templates used to render pages
   |              |
   |              |-- includes/                  #
   |              |    |-- navigation.html       # Top menu component
   |              |    |-- sidebar.html          # Sidebar component
   |              |    |-- footer.html           # App Footer
   |              |    |-- scripts.html          # Scripts common to all pages
   |              |
   |              |-- layouts/                   # Master pages
   |              |    |-- base-fullscreen.html  # Used by Authentication pages
   |              |    |-- base.html             # Used by common pages
   |              |
   |              |-- accounts/                  # Authentication pages
   |                   |-- login.html            # Login page
   |                   |-- register.html         # Registration page
   |
   |-- requirements.txt                          # Development modules - SQLite storage
   |-- requirements-mysql.txt                    # Production modules  - Mysql DMBS
   |-- requirements-pqsql.txt                    # Production modules  - PostgreSql DMBS
   |
   |-- .env                                      # Inject Configuration via Environment
   |-- config.py                                 # Set up the app
   |-- run.py                                    # Start the app - WSGI gateway
   |
   |-- ************************************************************************

App / Home Blueprint

The Home blueprint handles UI Kit pages for authenticated users. This is the private zone of the app - the structure is presented below:

< PROJECT ROOT >
   |
   |-- app/
   |    |-- base/                     # Base Blueprint - handles the authentication
   |    |-- home/                     # Home Blueprint - serve app pages (private area)
   |         |
   |         |-- templates/           # UI Kit Pages
   |              |
   |              |-- index.html      # Default page
   |              |-- page-404.html   # Error 404 - mandatory page
   |              |-- page-500.html   # Error 500 - mandatory page
   |              |-- page-403.html   # Error 403 - mandatory page
   |              |-- *.html          # All other HTML pages
   |
   |-- requirements.txt               # Development modules - SQLite storage
   |-- requirements-mysql.txt         # Production modules  - Mysql DMBS
   |-- requirements-pqsql.txt         # Production modules  - PostgreSql DMBS
   |
   |-- .env                           # Inject Configuration via Environment
   |-- config.py                      # Set up the app
   |-- run.py                         # Start the app - WSGI gateway
