✨ Environment

To use the starter, Python3 should be installed properly in the workstation. If you are not sure if Python is installed, please open a terminal and type python --version. Here is the full list with dependencies and tools required to build the app:

Python3 - the programming language used to code the app
GIT - used to clone the source code from the Github repository
Basic development tools (g++ compiler, python development libraries ..etc) used by Python to compile the app dependencies in your environment.
(Optional) Docker - a popular virtualization software

✨ Start the app in Docker

👉 Step 1 - Download the code from the GH repository (using GIT)

$ # Get the code
$ git clone https://github.com/app-generator/django-gradient-able.git
$ cd django-gradient-able

👉 Step 2 - Start the APP in Docker

$ docker-compose up --build

Visit http://localhost:5085 in your browser. The app should be up & running.

✨ Manual Build

Download the code

$ # Get the code
$ git clone https://github.com/app-generator/django-gradient-able.git
$ cd django-gradient-able

👉 Set Up for `Unix`, `MacOS`

Install modules via VENV

$ virtualenv env
$ source env/bin/activate
$ pip3 install -r requirements.txt

Set Up Database

$ python manage.py makemigrations
$ python manage.py migrate

Start the app

$ python manage.py runserver

At this point, the app runs at http://127.0.0.1:8000/.

👉 Set Up for `Windows`

Install modules via VENV (windows)

$ virtualenv env
$ .\env\Scripts\activate
$ pip3 install -r requirements.txt

Set Up Database

$ python manage.py makemigrations
$ python manage.py migrate

Start the app

$ python manage.py runserver

At this point, the app runs at http://127.0.0.1:8000/.

✨ Manage App `Users`

By default, the starter is not provided with users. To access the private pages and the admin section (reserved for superusers) follow up the next sections.

👉 Create `Superusers`

To access the admin section, Django requires superuser privilegies. Let's create a new superuser and access the admin section of the project:

$ python.exe manage.py createsuperuser
>>> Username (leave blank to use 'test'): test
>>> Email address: admin@appseed.us
>>> Password: *******
>>> Password (again): *******
>>> Superuser created successfully.

Once the superuser is successfully created, we can access the admin section:

http://localhost:8000/admin/ (make sure you have a / at the end).

👉 Create (Ordinary) Users

By default, the app redirects guest users to authenticate. In order to access the private pages, follow this set up:

Start the app via python manage.py runserver
Access the registration page and create a new user:
- http://127.0.0.1:8000/register/
Access the sign in page and authenticate
- http://127.0.0.1:8000/login/

✨ Codebase structure

The project is coded using a simple and intuitive structure presented below:

✨ Application Bootstrap Flow

The entry point of the project is the core.settings.py file where the project configuration is bundled. The most important files that make the project functional are listed below:

manage.py (saved in the root of the project) loads core/settings.py
core/settings.py:
- Loads the .env file (dynamic configuration)
- Loads the project routing:
  - core.urls.py
- Defines the templates directory
  - apps/templates
- Defines the INSTALLED_APPS section
  - apps.home - custom app that serve all pages
- If the DB_ENGINE variable is not present in the environment
  - SQLite persistence is used
- If the DB_ENGINE is present
  - The DB URI is built dynamically for MySql or PostgreSQL.

✨ Project Routing

The core file that bundles together all routing rules is core/urls.py.

The home application being a generic router that serves all pages defined in the templates/home directory, should be the last rule defined in the urlpatterns.

NOTE: all new apps, should be included above apps.home.urls generic rule.

urlpatterns = [
    path('admin/', admin.site.urls),          # Django admin route
    path("", include("apps.authentication.urls")), # Auth routes - login / register

    # ADD NEW Routes HERE

    # Leave `Home.Urls` as last the last line
    path("", include("apps.home.urls"))
]

✨ UI Assets and Templates

The project comes with a modern UI fully migrated and usable with Django Template Engine.

👉 Page Templates

All pages and components are saved inside the apps/templates directory. Here are the standard directories:

templates/layouts: UI masterpages
templates/includes: UI components (used across multiple pages)
templates/accounts: login & registration page
templates/home: all other pages served via a generic routing by apps/home app

< PROJECT ROOT >
   |
   |-- core/                           # Implements app configuration
   |-- apps/
   |    |
   |    |-- home/                      # A simple app that serve HTML files
   |    |-- authentication/            # Handles auth routes (login and register)
   |    |
   |    |-- static/
   |    |    |-- <css, JS, images>     # CSS files, Javascripts files
   |    |
   |    |-- templates/                 # Templates used to render pages
   |         |-- includes/             # HTML chunks and components
   |         |    |-- navigation.html  # Top menu component
   |         |    |-- footer.html      # App Footer
   |         |    |-- scripts.html     # Scripts common to all pages
   |         |
   |         |-- layouts/              # Master pages
   |         |    |-- base.html        # Used by common pages
   |         |
   |         |-- accounts/             # Authentication pages
   |         |    |-- login.html       # Login page
   |         |    |-- register.html    # Register page
   |         |
   |         |-- home/                 # UI Kit Pages
   |              |-- index.html       # Index page
   |              |-- page-404.html    # 404 page
   |              |-- *.html           # All other pages
   |
   |-- ************************************************************************

👉 Static Assets

The static assets used by the project (JS, CSS, images) are saved inside the apps/static/assets folder. This path can be customized with ease via ASSETS_ROOT variable saved in the .env file.

How it works

.env defines the ASSETS_ROOT variable
core/settings.py read the value of ASSETS_ROOT and defaults to /static/assets if not found:

# content of core/settings.py (truncated content)

ASSETS_ROOT = os.getenv('ASSETS_ROOT', '/static/assets')

All pages and components use the ASSETS_ROOT variable. Here is a sample extracted from templates/layouts/base.html:

<head>

    <!-- Source Code -->
    <link rel="stylesheet" href="{{ ASSETS_ROOT }}/css/style.css">

    <!-- RUNTIME -->
    <link rel="stylesheet" href="/static/assets/css/style.css">

At runtime, the href property is resolved to /static/assets/css/style.css based on the value saved in the .env file:

# No Slash at the end
ASSETS_ROOT=/static/assets

✨ Default Apps

The codebase comes with two simple apps that handle the authentication and serve all pages saved in the apps/templates/home directory.

👉 Authentication App

This default app defined in apps/authentication handles the authentication routes login, register. The most important files that make the authentication usable, are listed below:

forms.py - defines the Login, Registration forms
views.py - implements the login, registration flow
routes.py - map routing rules over the views
models.py - EMPTY file
- The extended user model is NOT provided

👉 Home App

This app returns all pages saved in the templates/home directory to authenticated users. In case a page is not found, a generic page is returned using a 404 HTTP error status.

✨ Customisation

👉 Set up the MySql Database

Note: Make sure your Mysql server is properly installed and accessible.

Step 1 - Create the MySql Database to be used by the app

Create a new MySql database
Create a new user and assign full privilegies (read/write)

Step 2 - Install mysqlclient package

$ pip install mysqlclient

Step 3 - Edit the .env to match your MySql DB credentials. Make sure DB_ENGINE is set to mysql.

DB_ENGINE : mysql
DB_NAME : default value = appseed_db
DB_HOST : default value = localhost
DB_PORT : default value = 3306
DB_USERNAME: default value = appseed_db_usr
DB_PASS : default value = pass

Here is a sample:

# .env sample

DB_ENGINE=mysql               # Database Driver
DB_NAME=appseed_flask         # Database Name
DB_USERNAME=appseed_flask_usr # Database User
DB_PASS=STRONG_PASS_HERE      # Password 
DB_HOST=localhost             # Database HOST, default is localhost 
DB_PORT=3306                  # MySql port, default = 3306

At this point, the app should use MySql for the persistence layer.

👉 Adding a new app

The existing codebase can be extended with ease with new apps and features. Here are the steps that create a new application named polls.

Create a new app using startapp command (make sure you are in the root of the project)

$ python manage.py startapp polls

Write a simple view for the new app - Edit polls/views.py

from django.http import HttpResponse

def index(request):
    return HttpResponse("Hello! This is the polls APP index.")

Create urls.py inside the polls directory

from django.urls import path

from . import views

urlpatterns = [
    path('', views.index, name='index'),
]

Update project routing - core/urls.py file:

urlpatterns = [
    path('admin/', admin.site.urls),         
    path("", include("apps.authentication.urls")), 

    # ADD NEW Routes HERE
    path('polls/', include('polls.urls')),  # <-- NEW

    # Leave `Home.Urls` as last the last line
    path("", include("apps.home.urls"))
]

Enable the new app - Update core/settings.py file:

... (truncated content)

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'polls',                       # <-- NEW
    'apps.home' 
]

... (truncated content)

Start the project and access the project in the browser:

http://localhost:8000/polls/

👉 Static Assets for `production`

As explained in the Static Assets section, the assets are managed via:

apps/static/assets - the folder where JS, CSS, and images files are saved
ASSETS_ROOT - environment variable, that defaults to /static/assets if not defined

In production, the contents of the apps/static/assets files should be copied to an external (public) directory and the ASSETS_ROOT environment variable updated accordingly.

For instance, if the static files are copied to https://cdn.your-server.com/gradient-able-assets, the .env file should be updated as below:

# No Slash at the end
ASSETS_ROOT=https://cdn.your-server.com/gradient-able-assets
