This rails engine implements a Decidim component that allows to the administrators to configure crowfunding campaigns for a participatory space.


This plugin provides:

  • A CRUD engine to manage crowfunding campaigns.

  • Public views for crowfunding campaigns via a menu inside each participatory space.

  • An interface with Census API.

  • Rake tasks necessary to automatize recurrent payments.


Add the following lines to your application’s Gemfile:

gem 'decidim-crowdfundings'

And then execute:

bundle exec rails decidim_crowdfundings:install:migrations
bundle exec rails db:migrate
bundle exec rails generate decidim:crowdfundings:install

Then you’ll need to configure the environment variable CENSUS_URL to point to the running instance of census.


In order to execute the tests data from iban_bic gem must be populated as well:

bundle exec rails db:migrate RAILS_ENV=test

Docker & Docker compose

This engine is supplied with Docker compose files. If you want to use them you need to check the spec/decidim_dummy_app/database.yml and adjust the database settings:

default: &default
  adapter: postgresql
  encoding: unicode
  # For details on connection pooling, see rails configuration guide
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  host: <%= ENV.fetch("DATABASE_HOST") { "db" } %>
  username: <%= ENV.fetch("DATABASE_USERNAME") { "admin" } %>
  password: <%= ENV.fetch("DATABASE_PASSWORD") { "admin" } %>

If you desire to use different settings you need to check the Docker compose settings and adjust the setup of the PostgreSQL image.

Finally remember that the Docker file do not includes any command relative to the database setup. Due to this limitation, the first time that you execute the app you must execute the following commands:

docker-compose run web bash
cd spec/decidim_dummy_app
bundle exec rails db:create
bundle exec rails db:migrate
bundle exec rails db:seed

Rake tasks

This engine provides the following rake tasks:


This task collects all recurrent contributions that need to be renewed. Ideally it should be automatically executed at least once per month.


This task collects all contributions in pending status. Then proceeds querying Census about the payment method status. According to Census response the contribution payment will be accepted or rejected. This process should be executed several times per month, ideally on periods of low load. It should be executed at least once before the decidim_crowdfundings:recurrent_contributions is executed.
