Decidim::ComparativeStats

Allows to compare different Decidim sites by accessing their GraphQL API and generate graphs.

NOTE: This module is in beta status, feel free to report issues or contribute in it!

This module works by connecting to several Decidim API's. Just go to your your-decidim-installation.org/admin/comparative_stats and add endpoints to compare. For instance, Decidim Barcelona endpoint is https://www.decidim.barcelona/api

Then, go to graphs and see some nice graphs!

Graphs can be embedded anywhere independently, just use the button embed <> and copy the code to any other place.

The generated code will look something like:

<iframe
  src="http://your_url/comparative_stats/widgets/global_stats.html"
  frameborder="0"
  width="100%"
  height="420"
  scrolling="vertical"></iframe>

You might want to customize the height parameter to match your particular case.

A real example comparing the participatory processes carried out by the cities of Barcelona and Helsinki in 2019

Add this line to your application's Gemfile:

gem "decidim-comparative_stats", git: "https://github.com/Platoniq/decidim-module-comparative_stats", branch: "master"

And then execute:

bundle
bundle exec rails decidim_comparative_stats:install:migrations
bundle exec rails decidim_comparative_stats:webpacker:install
bundle exec rails db:migrate

Depending on your Decidim version, choose the corresponding Awesome version to ensure compatibility:

API queries are cached 1 hour by default. This can be tuned by creating an initializer in your Decidim installation. For instance, create the file config/initializers/comparative_stats.rb with this content:

# frozen_string_literal: true

Decidim::ComparativeStats.configure do |config|
  config.stats_cache_expiration_time = 2.hour
end

To start contributing to this project, first:

• Install the basic dependencies (such as Ruby and PostgreSQL)
• Clone this repository

Decidim's main repository also provides a Docker configuration file if you prefer to use Docker instead of installing the dependencies locally on your machine.

You can create the development app by running the following commands after cloning this project:

bundle
DATABASE_USERNAME=<username> DATABASE_PASSWORD=<password> bundle exec rake development_app

Note that the database user has to have rights to create and drop a database in order to create the dummy test app database.

Then to test how the module works in Decidim, start the development server:

cd development_app
DATABASE_USERNAME=<username> DATABASE_PASSWORD=<password> bundle exec rails s

In case you are using rbenv and have the rbenv-vars plugin installed for it, you can add the environment variables to the root directory of the project in a file named .rbenv-vars. If these are defined for the environment, you can omit defining these in the commands shown above.

Please follow the code styling defined by the different linters that ensure we are all talking with the same language collaborating on the same project. This project is set to follow the same rules that Decidim itself follows.

Rubocop linter is used for the Ruby language.

You can run the code styling checks by running the following commands from the console:

bundle exec rubocop

To ease up following the style guide, you should install the plugin to your favorite editor, such as:

• Atom - linter-rubocop
• Sublime Text - Sublime RuboCop
• Visual Studio Code - Rubocop for Visual Studio Code

To run the tests run the following in the gem development path:

bundle
DATABASE_USERNAME=<username> DATABASE_PASSWORD=<password> bundle exec rake test_app
DATABASE_USERNAME=<username> DATABASE_PASSWORD=<password> bundle exec rspec

Note that the database user has to have rights to create and drop a database in order to create the dummy test app database.

In case you are using rbenv and have the rbenv-vars plugin installed for it, you can add these environment variables to the root directory of the project in a file named .rbenv-vars. In this case, you can omit defining these in the commands shown above.

If you want to generate the code coverage report for the tests, you can use the SIMPLECOV=1 environment variable in the rspec command as follows:

SIMPLECOV=1 bundle exec rspec

This will generate a folder named coverage in the project root which contains the code coverage report.
