This is the source code of the ETM Pro: an online web app that let you create a future energy scenario for various countries, municipalities, neighbourhoods and more. This software is Open Source, so you can fork it and alter at your will.

If you have any questions, please contact us.

The ETM pro is released under the MIT License.

• master: Working branch and is tracked by the ETM beta server
• production: Tracks the ETM production server

New users are recommended to use Docker to run ETEngine. Doing so will avoid the need to install additional dependencies.

1. Get a copy of ETModel. You may choose to clone the repository using Git, or download a ZIP archive from Github.

2. Build the ETModel image:

   docker-compose build

3. Install dependencies and seed the database:

   docker-compose run --rm web bash -c 'bin/rails db:drop && bin/setup'

   This command drops any existing ETModel database; be sure only to run this during the initial setup! This step will also provide you with an e-mail address and password for an administrator account.

4. By default, ETModel will send requests to the beta (staging) version of ETEngine. This is used for testing purposes and is more frequently updated than the live (production) version.

   Run ETEngine locally

   If you wish to run a local copy of ETEngine, ETModel must be told where to find its API. You must first find your machine's local/private IP address; ETModel will use this to send messages directly to ETEngine, and also by your browser when you are using the ETModel application to create scenarios. To get your IP address, run:

   ipconfig getifaddr en0   # on macOS
   hostname -I              # on Linux
   ipconfig                 # on Windows

   • macOS
   • Ubuntu

   Create a file called config/settings.local.yml containing:

   ete_url: https://YOUR_IP_ADDRESS:3000

   Branches

   When running ETEngine locally, be sure to use the same branch or tag for ETModel, ETEngine, and ETSource. You are likely to encounter errors if you fail to do so.

   For example, if you wish to run the latest version all three should be set to the master branch. If you wish to run the production release from March 2022, they should all use the same tag:

   cd ../etengine && git checkout 2022.03
   cd ../etsource && git checkout 2022.03
   cd ../etmodel  && git checkout 2022.03

5. Launch the containers:

   docker-compose up
   

   After starting application will become available at https://localhost:3001 after a few seconds. This is indicated by the message "Listening on https://0.0.0.0:3001".

Mac users should be able to install the following prerequisites with Homebrew, Ubuntu users can use apt-get.

• Ruby 2.6.6 and a Ruby version manager such as rbenv
• Mysql database server
• Yarn 1.22.5

• Pull this repository with git clone git@github.com:quintel/etmodel.git

  • Local Engine You can communicate with either a local version of ETEngine, or one of our servers by specifying the ete_url in config.yml. To use a local version, change the standard beta server url to https://localhost:<PORT> based on which port you are running the Engine on.
  • Database password If you added a username and password to your mysql service, please replace the standard login info in database.yml with your own credentials.

• Run bundle install and yarn install to install all the dependencies

• Create and fill local database with rake db:setup and RAILS_ENV=test rake db:setup

• Fire up your local server with rails server -p3001

• Go to localhost:3001 and you should see the ETM pro!

If you want to get admin access to your own page, the easiest way to do so is to create an Admin User through the console and follow instructions:

rake db:create_admin

If you encounter a bug or if you have a feature request, you can either let us know by creating an Issue or you can try to fix it yourself and create a pull request.
