The Proposals module adds one of the main components of Decidim: allows users to contribute to a participatory process by creating proposals.


Proposals will be available as a Component for a Participatory Process.


Add this line to your application's Gemfile:

gem 'decidim-proposals'

And then execute:


Configuring Similarity

pg_trgm is a PostgreSQL extension providing simple fuzzy string matching used in the Proposal wizard to find similar published proposals (title and the body).

Create config variables in your app's /config/initializers/decidim-proposals.rb:

Decidim::Proposals.configure do |config|
  config.similarity_threshold = 0.25 # default value
  config.similarity_limit = 10 # default value

similarity_threshold(real): Sets the current similarity threshold that is used by the % operator. The threshold must be between 0 and 1 (default is 0.3).

similarity_limit: number of maximum results.

This module includes the following models to Decidim's Global Search:

  • Proposals

Participatory Texts

Participatory texts persist each section of the document in a Proposal.

When importing participatory texts all formats are first transformed into Markdown and is the markdown that is parsed and processed to generate the corresponding Proposals.

When processing participatory text documents three kinds of secions are taken into account.

  • Section: each "Title 1" in the document becomes a section.
  • Subsection: the rest of the titles become subsections.
  • Article: paragraphs become articles.
