Django Configuration

General Information

Configuring the Django Web Framework and its dependencies.


The EXAMPLE sections of code end up building an inventory website.


Checklist


Database: MariaDB

Configuring the MariaDB Database.

  • Configure MariaDB to listen only on localhost
    vim /etc/my.cnf
     
    [mysqld]
    bind-address=127.0.0.1
  • Start/Enable the database
    systemctl enable mariadb
    systemctl start mariadb
  • Run secure setup
    mysql_secure_installation
    • Prompts for the following:
      • Current password for root (should be none, just press enter)
      • Set database root password
      • Remove anonymous users
      • Disallow root logins remotely
      • Remove test databases
      • Reload privilege tables
  • Connect to the database
    mysql -u root -p
  • Create your project's database
    create database myprojecthere character set utf8;
  • Create a database user that Django will use
    create user appuserhere@localhost identified by 'PASSWORDHERE';
  • Grant permissions for the app user on your project's database
    grant all privileges on myprojecthere.* to appuserhere@localhost;
  • Flush privileges
    flush privileges;

Django

Configuring Django.

  • Verify django works
    python
    >>> import django
    >>> print(django.get_version())
    >>> exit()
  • Create a directory to store the project
    mkdir /home/django
    cd /home/django
  • Create a new Django project
    django-admin startproject myprojecthere
    cd /home/django/myprojecthere
  • Create a new Django application inside of the project
    python manage.py startapp myapphere
  • Edit project settings (/home/django/myprojecthere/myprojecthere/settings.py)
    # Allowed Referrer Hosts (hostname and any cnames)
    ALLOWED_HOSTS = ['djangoserver.mycorps.domain.org','myapp.mycorps.domain.org']
     
    # Application definition (add the application, the rest are built in)
    INSTALLED_APPS = [
         # APPNAME.apps.APPCLASSNAME -> see ../myapphere/apps.py
        'myapphere.apps.MyapphereConfig',    # add your application here
        'django.contrib.admin',
        'django.contrib.auth',
        'django.contrib.contenttypes',
        'django.contrib.sessions',
        'django.contrib.messages',
        'django.contrib.staticfiles',
    ]
     
    # Static files (CSS, JavaScript, Images)
    #https://docs.djangoproject.com/en/1.11/howto/static-files/
    STATIC_URL = '/static/'
    STATIC_ROOT = '/var/www/static/'
  • Edit project settings (/home/django/myprojecthere/myprojecthere/settings.py)
    # Database Configuration
    # https://docs.djangoproject.com/en/1.11/ref/settings/#databases
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.mysql',
            'NAME': 'myprojecthere',
            'USER': 'appuserhere',
            'PASSWORD': 'PASSWORDHERE',

            },
        }
    }
  • Run the initial migrate command to create database tables for built in apps that come with Django
    cd /home/django/myprojecthere
    python manage.py migrate
  • Describe your data models (objects that will be stored in the database) (/home/django/myprojecthere/myapphere/models.py) EXAMPLE

    ####---- End of Logging Config ----####
  • Create logging directory and setup ownership/permissions
    mkdir /var/log/myprojecthere
    chown :apache /var/log/myprojecthere
    chmod g+rwx /var/log/myprojecthere
  • Create an admin user
    python manage.py createsuperuser
  • Make your models/objects available for editing in the admin portal (/home/django/myprojecthere/myapphere/admin.py)
    # -*- coding: utf-8 -*-
    from __future__ import unicode_literals
     
    from django.contrib import admin

    # Make Class Available in Admin Portal (see /home/django/myprojecthere/myapphere/models.py)
    from .models import AssetEntry
    admin.site.register(AssetEntry)

A URL+View will generate a web page.

Project Level URLs File

  • Edit project URLs (/home/django/myprojecthere/myprojecthere/urls.py)
     # add the "import include" part or you won't be able to refer to app level url files
    from django.conf.urls import url, include
    from django.contrib import admin
     
    # URL Regex Patterns - Map URIs to App's url file for additional matching
    urlpatterns = [
        # No URI following site name (default app to use)
        url(r'^$', include('myapphere.urls')),

        url(r'^myapphere/', include('myapphere.urls')),
        # Included /admin URI
        url(r'^admin/', admin.site.urls),
    ]


App Level URLs File

  • Create a new App level URLs file (/home/django/myprojecthere/myapphere/urls.py) EXAMPLE
    # urls.py - App URLs Map to App Views
    from django.conf.urls import url
     
    from . import views
     
    urlpatterns = [
      # "/myapphere/" beginning is implied because we are in the "myapphere" urls file already
     
      # /myapphere/  -  All Devices, All Environments (the index)
      url(r'^$', views.index, name='index'),
     
      # /myapphere/stats  -  All Devices, Statistics
      url(r'^stats/$', views.stats, name='stats'),
     
      # /myapphere/env_name  -  All Devices, Specific Environment
      url(r'^(?P<env_name>(dev|test|prod))/$', views.env, name='env'),
     
      # /myapphere/device_type/  - Specific Device, All Environments
      url(r'^(?P<device_type>(firewalls|routers|servers|storage|switches|workstations))/$', views.asset_type_all_env, name='asset_type_all_env'),

      url(r'^(?P<device_type>(firewalls|routers|servers|storage|switches|workstations))/(?P<env_name>(dev|test|prod))/$', views.type_env, name='type_env'),
     
      # /myapphere/<asset_hardware> - Physical or Virtual
      url(r'^(?P<asset_hardware>(physical|virtual))/$', views.asset_hardware, name='asset_hardware'),
    ]
  • Edit the App Views that are loaded depending upon URL match(/home/django/myprojecthere/myapphere/views.py) EXAMPLE
    # views.py - URLs are mapped to views
    # -*- coding: utf-8 -*-

Apache

Configuring Apache to pass traffic to the application.

  • Configure Apache's mod_wsgi for the application (new file)
    vim /etc/httpd/conf.d/myapphere.conf
     
    # Asset List Django/WSGI Config
     
    # WSGIScriptAlias: The base URL to serve the application from
    WSGIScriptAlias / /home/django/myprojecthere/myprojecthere/wsgi.py
     
    # WSGI Daemon Process Config
    WSGIDaemonProcess myapphere python-path=/home/django/myprojecthere
    WSGIProcessGroup myapphere
     
    # Location of Django Application and wsgi.py config
    <Directory /home/django/myprojecthere/myprojecthere>
      <Files wsgi.py>
        Require all granted
      </Files>
    </Directory>
     
    # Static files (admin interface and style sheet)
    Alias /static/ /var/www/static/
    <Directory /var/www/static/>
      Require all granted
    </Directory>
  • Configure the virtual host (new file)
    vim /etc/httpd/conf.d/vhosts.conf
     
    # Virtual Host Config
     
    # Redirect shortname to fully qualified
    <VirtualHost *:80>
      ServerName djangoserver
      Redirect "/" "http://djangoserver.mycorps.domain.org/"
    </VirtualHost>
     
    # Redirect all http to https
    <VirtualHost *:80>
      ServerName djangoserver.mycorps.domain.org
     
      <IfModule mod_rewrite.c>

    SSLCertificateKeyFile /etc/pki/tls/certs/current_key.key
    SSLCertificateChainFile /etc/pki/tls/certs/current_ca.crt
  • Start and Enable Apache
    systemctl start httpd
    systemctl enable httpd

Django: Authentication

Adding authentication to Django requires basic auth to be setup first, as LDAP auth builds upon it.

Basic authentication uses Django local user accounts.

  • Edit Project Settings (/home/django/myprojecthere/myprojecthere/settings.py)
    # Redirect Successful Logins Here
    LOGIN_REDIRECT_URL = '/myapphere/'
     
    # Ensure contrib.auth is added to installed apps:
    # Application definition
    INSTALLED_APPS = [
        'myapphere.apps.MyapphereConfig',
        'django.contrib.admin',
        'django.contrib.auth',    # must exist for basic auth to work
    ...
    ]
  • Add login and logout URLs to project URLs (/home/django/myprojecthere/myprojecthere/urls.py)
    # auth views - authentication login/logout module
    from django.contrib.auth import views as auth_views
     
    # URL Patterns - Map to Projects Within Django
    urlpatterns = [
        ...
        # Login URLs
        url(r'^login/$', auth_views.login, {'template_name': 'login.html'}, name='login'),
        url(r'^logout/$', auth_views.logout, {'next_page': '/login/'}, name='logout'),
        ...
    ]
  • Edit the application views (/home/django/myprojecthere/myapphere/views.py)
    # Require login decorator
    from django.contrib.auth.decorators import login_required
     
    # Put login decorator before every function definition that you want to require login to view:
    #-> Require login for the view following it <-#
    @login_required(login_url="/login/")
     
    def index(request):
  • Create a HTML Login Page (/home/django/myprojecthere/myapphere/templates/login.html)
    <!DOCTYPE html>
    <html>
    <head>
      <meta charset="utf-8">
      <title>{% block title %}Asset List{% endblock %}</title>
    </head>
     
    <body>
      <header>
        <h1>Asset List</h1>
        {% if user.is_authenticated %}
          Greetings, {{ user.username }}.
          <a href="{% url 'logout' %}">logout</a>
        {% endif %}
      </header>
     
      <hr>
      <main>
      <h2>Login</h2>
      <form method="post">
        {% csrf_token %}
        {{ form.as_p }}
        <button type="submit">Login</button>
      </form>
      </main>
      <hr>
     
    </body>
    </html>

Django: Jquery

Jquery can be added in order to enable an Export as CSV and/or Excel buttons.

Reference: Export Jquery Buttons: https://github.com/kayalshri/tableExport.jquery.plugin

  • From the reference link, download:
    • jquery.base64.js
    • tableExport.js
  • Search the internet for CSV and XLS icons. Download them.
    • CSV = save as “csv.png”
    • XLS = save as “xls.png”
  • Save the Javascript files and small pictures (CSV/XLS) into the same directory as the style sheet
    /home/django/myprojecthere/myapphere/static/myapphere/
  • Install the Django Jquery integration
    pip install django-jquery
  • Add Jquery to the “INSTALLED_APPS” list (/home/django/myprojecthere/myprojecthere/settings.py)
    # Application definition
    INSTALLED_APPS = [
        'jquery',
  • Add jquery to HTML templates
    <!-- Export button jquery support (https://github.com/kayalshri/tableExport.jquery.plugin) -->
    <script type="text/javascript" src="{% static 'js/jquery.js' %}"></script>
    <script type="text/javascript" src="{% static 'myapphere/tableExport.js' %}"></script>
    <script type="text/javascript" src="{% static 'myapphere/jquery.base64.js' %}"></script>
     
    <!-- Export Buttons -->
    <a href="#" class="plain" onclick="$('#assetlist').tableExport({type:'csv',escape:'false'});"><img src="{% static 'myapphere/csv.png' %}" width="24px" title="Export CSV"></a>
    <a href="#" class="plain" onclick="$('#assetlist').tableExport({type:'excel',escape:'false'});"><img src="{% static 'myapphere/xls.png' %}" width="24px" title="Export Excel"></a>
