1. Create a new Django project using Aldryn Django

About this tutorial

In this tutorial you will create and deploy a new project using Aldryn Django. Aldryn is a wrapper around Django, the most popular Python web application framework. Aldryn provides automatic configuration and integration with cloud services such as database, media storage and so on.

Important

Unless you are sure you wish to use Aldryn, we recommend starting with our standard Django tutorial instead.

Set up a project in the Cloud

If you have not already done so, you will need to set up the local development environment.

Create the project

In the Divio Control Panel, create a new project.

Any web application in any language can run on Divio, as long as there is nothing that prevents its being Dockerised. For convenience we some ready-to-go project types for applications built in Java, PHP, Node and other languages. Use of these is optional. You can also start with a Build your own project, in which you build your application from a blank sheet.

For this tutorial, select the following options for your project (other options should be left on their default settings):

  • Platform: Python 3.x

  • Project type: Django

Django 2.2

At the time of writing, version 2.2 is Django’s Long-Term Support release, and is guaranteed support until at least April 2022. This is the version currently selected by default in Divio projects.

Divio projects use Git for code management. We provide a Git server that your projects will use by default; you can also choose to use another Git service if you prefer. For this tutorial, use our Git server.

Hit Continue, then select the free Developer plan for this project (the Developer plan is fully-featured and provides all you need to work on an application up to the point of putting it into production).

It takes a few moments to create the project. During this process, the Control Panel defines the basic project files for your application by adding commits to its repository. This could include assembling its Dockerfile and other files, depending on the project type.

Project environments

'Project Dashboard'

Your project has two independent server environments, Test and Live . The Test and Live environments have their own services, and unique environment variables to configure access to them. They can be deployed independently, and can also be configured to track different Git branches.

Deploy the project

Once the project has been fully created, use the Deploy button to deploy the Test server.

The deployment process first builds the Docker image from the Dockerfile, and then launches a Docker container from the image. The container environment will include automatically-configured environment variables for connections to services such as the database, media storage and so on.

Typically, this takes a minute or so.

Open the Test environment website

Once you have successfully deployed the Test environment, the Control Panel will indicate this in the interface with a Last deployment successful at … message and the project URL in the Test environment pane will display as a link, for example https://tutorial-project-stage.us.aldryn.io. Select the link to access the project.

Since this is your own project, you can use our single-sign-on to log in by selecting Log in with Divio. You’ll see the familiar Django admin for a new project.

About deployment

Any time new changes to the project code are committed to its repository, the Control Panel will indicate this with a message showing the number of undeployed commits for each of its server environments.

'Deployed and undeployed commits'

New code and configuration changes applied via the Control Panel (to subscriptions, cron jobs, environment variable, domains or other settings) will not take effect on either server environment until it is deployed once again.

If for whatever reason a deployment fails, there will be no down-time - the containers that are currently running will continue running, and the failing changes will not be deployed.

Explore the Dashboard

The Divio project Dashboard provides you with access to useful controls and information for the project. They are fairly self-explanatory and at this stage you don’t need to interact with any of them, but it’s worth familiarising yourself with what’s available.

Enable Beta options

We often expose new functionality to users who opt-in to Beta features. You can do this in your account settings.
