Random Drankspel

This is the repository for the Random Drankspel generator. This application is designed to create a way to pick a random drinking game.

Getting Started

This project is built using both Django for the backend and VueJS for the frontend.

Setup backend

0. Get at least Python 3.8 installed on your system.
1. Clone this repository.
2. If pip3 is not installed on your system yet, execute apt install python3-pip on your system.
3. Also make sure python3-dev is installed on your system, execute apt install python3-dev.
4. Install Poetry by following the steps on their website. Make sure poetry is added to PATH before continuing.
5. Make sure poetry uses your python 3 installation: poetry env use python3.
6. Go to the backend directory.
7. Run poetry install to install all dependencies.
8. Run poetry shell to start a shell with the dependencies loaded. This command needs to be ran every time you open a new shell and want to run the development server.
9. Run cd website to change directories to the website folder containing the project.
10. Run ./manage.py migrate to initialise the database and run all migrations.
11. Run ./manage.py createsuperuser to create an administrator that is able to access the backend interface later on. The password you set here will not be used as the openid server will be used for identification, be sure to set the super user to your science login name.
12. Run ./manage.py runserver to start the development server locally.

Now your server is setup and running on localhost:8000. The administrator interface can be accessed by going to localhost:8000/admin.

Setup frontend

1. Install the Yarn package manager
2. Clone this repository
3. Go to the frontend.
4. Use yarn install to install the required packages
5. Use yarn serve to serve the test server
6. Note that you might need to setup a .env file in the root of the cloned repository. The .env file will need to look something like the following (for local development):

VUE_APP_BACKEND_URI=http://localhost:8000/api/v1

Docker container

A Dockerfile is included in the respective folders of both the backend and frontend of the repository. For building the docker file, you can run docker build -t [tag] . in the respecitve folder of the docker you want to build. An example docker-compose file is added as docker-compose.yml.example. Note that for running this docker-compose file, the setup.sql in backend/database_init should be configured as well.

Setting environment variables for the frontend

Normally, environment variables are included during build and can not be changed afterwards. This is a problem when building a docker container which can be applied to different scenarios (e.g. with different API servers). Due to this fact, environment variables can be either included during build with a .env file in the root directory or with docker environment variables afterwards. Using docker environment variables will overwrite the environment variables included during build.

Environment variables that are available and should be overwritable by docker environment variables later should be included in the docker.blueprint.env file. Note that this file must use ' for indicating strings and the format is as follows:

    '[NAME_OF_VARIABLE_IN_VUE]': '${NAME_OF_ENV_VARIABLE}'

Before starting the nginx process, the docker environment variables will be set under the window.__env__ variable in the index.html file.

Using environment variables for the frontend

To use environment variables that can be set during runtime (with docker environment variables), add the variable to the docker.blueprint.env file as explained above. Then use the getEnvVar function in src/util/env.ts for getting the value of an environment variable. This function will first check wether it is set in the window.__env__ variable and will then look if it is an environment variable.

Voice assistants

The backend of this project supports the uses of Voice assistants to interact with the drinking games registered. Look at the method below to find out how to use them on your platform.

Siri

Siri natively support shortcuts. It is very easy to interact with this project via Siri. Setup a shortcut in the Shortcuts app on iOS. Alternatively, you can use this link to import a Dutch version of the shortcut (change the trigger to English for an English version).

Google Assistant

The Google Assistant side of this project is more complex, as Google has more features for adding Voice assistants to its own Google Assistant. We will be using Dialogflow for interacting with our voice assistant. The steps how to set this up are displayed below:

1. Setup a voice assistant on Google's Dialogflow platform.
2. Make sure to setup a service account for the Dialogflow project such that our application can interact with it later.
3. Download the JSON key file and set the GOOGLE_APPLICATION_CREDENTIALS environment variable (either in the docker-compose.yml file or on your own machine) to the absolute path to the credentials file.
4. Set the GOOGLE_AGENT_NAME environment variable to the name of the agent displayed in the Dialogflow console.
5. Set the GOOGLE_INTENT_TRIGGER environment variable to the trigger value (such as Give a random drinking game).
6. Set the GOOGLE_INTENT_RESPONSE environment variable to the response value (such as Here is your drinking game: {}). Note that the response will be formatted by Python, and using {} is obligatory (the random drinking game will be substituted with it).
7. Run the server.
8. Execute manage.py reset_dialgflow_agent to create the needed intent within Dialogflow.
9. Setup the fullfillment URL within the Fullfillment tab in the Dialogflow console. Make sure your URL ends in /api/dialogflow (the endpoint for dialogflow is located there).
10. You can now try out the Voice assistant in the Dialogflow console and add it to your phone.
