Usage

To configure a working interactive map in your Decidim application, you must define before :

• MAPS_API_KEY env var
• Uncomment the maps section in decidim initializer development_app/config/initializers/decidim.rb:38
• Define :
  • Assemblies with scope
  • Scope with GeoJSON content
  • PP with linked assemblies enabled (geocoding address for PP is not required)

Seeds should create expected resources see seeds file

Installation

Add this line to your application's Gemfile:

gem "decidim-homepage_interactive_map", git: "https://github.com/OpenSourcePolitics/decidim-module-homepage_interactive_map.git"

And then execute:

bundle
bundle exec rake decidim_homepage_interactive_map:install:migrations
bundle exec rake db:migrate
bundle exec rake decidim_homepage_interactive_map:webpacker:install

• On OSX:

brew install proj
bundle config set build.rgeo-proj4 --with-proj-dir="/opt/homebrew/"
bundle pristine rgeo-proj4
bundle install

• On Ubuntu:

sudo apt update && sudo apt install libproj-dev proj-bin -y
bundle config set build.rgeo-proj4 --with-proj-dir="/usr/local/bin/"
bundle pristine rgeo-proj4
bundle install

How to use

Existing positions

bundle exec rake decidim_homepage_interactive_map:repair_data

New positions

No need to do anything, the module will automatically transpose the scope position.

In Decidim's backoffice, enable Interactive map content block.

How it works

1. The content block will first ensure map api key is defined.
2. Ensure linked assemblies are present
3. Load a leaflet map inside the content block
4. Fetch assemblies and scopes
5. Apply GeoJSON as zone layer
6. Define markers for each assemblies
7. Load participatory process
   • If PP has location, places the marker at the defined address
   • Otherwise, place the participatory process on the top right corner of assemblie marker (like a notification badge)
