The frontend code is located in the assets folder.
It's a mixture of old jQuery code and newer React code.
The code is built with webpack and transpiled using Babel.
Some static files are still stored in files/static, but should be moved to assets and included using webpack.
Python 3 with Django is used as a backend and is mostly located in the apps folder.
Django templates are in templates folder.
The API uses Django REST framework

cd onlineweb4The easiest way to get started with development is to use the provided Docker images. On the other hand on slower machines Docker might be noticeable slower in which case a local installation using virtualenv can be preferred.
To fire up the dev environment, you should use Docker. Following that, you will need docker-compose, which can be installed following this guide.
There is a Makefile located in the root directory. This can be used to manage the application without direct interaction with docker, docker-compose, et al.
If you can't use make, you can fire up the dev environment by issuing docker-compose up -d.
If the site doesn't load properly the first time you are running the project, you might need to restart Docker once by running docker-compose restart.
A few packages are required to build our Python depedencies:
- libjpeg-dev
- ghostscript
If these aren't already installed poetry will likely fail to build the packages.
Onlineweb4 is setup to use the Poetry for dependency mangement.
To install dependencies run poetry install. If you're system doesn't have a compatible version of python, 3.7.x,
you can use pyenv.
To start the server firstly run the database migrations with python manage.py migrate, and run the server with python manage.py runserver.
Next, you need to fire up the front-end stuff, by running npm install followed by npm start.
The project should now be available at http://localhost:8000
After installing Docker and docker-compose, Download dependencies by running
make buildYou also need to set up the database, by running
# Enter the bash-terminal in the Docker container
make bash-backend
# Run the migrations
python manage.py migrateFor your convenience, you can also just run make migrate
To exit the Docker bash-terminal, use ^D (ctrl + D) or exit
And to be able to log in, you should create a superuser, a user with all types of permissions by default.
# If you aren't already in the bash-terminal in Docker
make bash-backend
# Create a super user from inside the container
python manage.py createsuperuserNow follow the instructions by supplying a name, password and an email.
You can then start Onlineweb4 by running
make startAnd your local version of Onlineweb4 should be available on http://localhost:8000!
You can stop it with make stop
To view output from onlineweb4, run make logs. To view output from a specific service (e.g. django), use one of the following:
OW4_MAKE_TARGET=django make logs # for django
OW4_MAKE_TARGET=webpack make logs # for the frontendAfter doing changes to a model, you will need to make an migration for the database-scheme. You can automatically create those commands by running the following:
make makemigrationsNote: we run format-linting on our migration files. Luckily we have set up the make makemigrations command to also
automatically format the created files. So if you use our command you should not need to do anything more. If you
are oldschool and prefer running ./manage.py makemigrations yourself, then you will need to either run black
afterwards, or run make lint-backend-fix after creating the migrations, so that they are properly formatted. You
could also look at the Makefile to see how we redirect the output if you want to do so yourself.
Pushes made to the main branch will trigger a redeployment of the application on dev.online.ntnu.no.
Pull requests trigger containerized builds that perform code style checks and tests. You can view the details of these tests by clicking the "detail" link in the pull request checks status area.
Builds will fail if our requirements for code style are not met. To ensure that you adhere to our code guidelines, we recommend you run linting tools locally before pushing your code. This can be done by running make lint, and you can automatically fix the backend linting by running make lint-backend-fix. Running make test will run our tests and linters all at once. Look to our Makefile for more specific commands.
Running make test frequently can be quite inefficient, which is why we recommend using editors that support linting your code as you go. For JavaScript, we use ESLint, with editor plugins available here. Correspondingly, we use stylelint for our stylesheets, with editor plugins available here. For Python, we use Black, isort and Flake8.
We highly recommend setting up your editor to automatically fix linting issues, which can be done for Black, and isort
In dotkom, we find that PyCharm is a great IDE that is well suited for contributing to onlineweb4. It'll come with support for ESLint, stylelint, and PEP 8 out of the box, and can be set up to run isort and Flake8 with some ease. We recommend it to our beginners who don't want to spend a lot of time setting up the plugins or extensions mentioned above, or don't have any preferences of their own yet. You can apply for a free student license here.
Onlineweb4 comes with an API located at /api/v1.
Autogenerated Swagger-docs can be found at /api/v1/docs.
Some endpoints require user authentication. See OAuth/OIDC.
Onlineweb4 has an Oauth2/OIDC-provider built-in, allowing external projects to authenticate users through Onlineweb4.
Auth0: Which flow should I use?
Digital Ocean: Introduction to Oauth 2
Auth0: Authorization Flow with PKCE - Single Page Apps
To authenticate users through https://online.ntnu.no, contact [email protected] for issuing a new client.
Follow the steps in Usage in a project for how to use the client information.
Initialize OpenID Connect by creating an RSA-key:
docker-compose run --rm django python manage.py creatersakeygo to localhost:8000/admin and log in with your administrator user.
Scroll to OpenID Connect Provider and add a new Client.
Fill in the information related to the selected flow (see linked documentation on flows).
Upon saving, a client-ID and client secret is generated for you. Revisit the client you created to retrieve the id and secret.
Automated configuration and all endpoints
There are many packages that provide oauth2/oidc-helpers. These can be quite helpful to automate much of the OAuth2-flow.
If you have configured your client correctly, the following cURL-commands are the equivalent of the authorization code flow and illustrate how the HTTP-requests are setup.
curl -v http://{url:port}/openid/authorize?\
client_id={your client_id}&\
redirect_uri={your configured callback url}&\
response_type={your configured response type}&\
scope={your configured scopes}&\
state={persistant state through the calls}&\Note: Two common scopes are openid and onlineweb4
This will trigger a 302 Redirect where the user will be asked to login to Onlineweb4.
Upon successfull login, the user are redirect to your configured callback url with ?code={authorization_code}&state{persistant state} added to the url.
Retrieve the code from the URL (and check that the state has not been tampered with, i.e. still is the same one.)
Exchange the code for an access token which will be used to identify the user in your application.
curl -v http://{url:port}/openid/token?
\grant_type={grant, i.e. the content of the parenthesis of the response type}
\code={code from previous step}This response will contain some basic information about the user, based on which scopes you requested, as well as an access token which can be added to the authorization header to request data from the API.
To use the access token, add Authorization: Bearer {token} to your requests to the API.
As a last step, basic user information can be retrieved from the endpoint /openid/userinfo.
This endpoint requires the Authorization-header to be set as mentioned above and the profile-scope to have been requested.
More information, such as email can be retrieved if the email-scope have been requested.
The full set of scopes for userinfo are: [email, address, phone, offline_access].
