How to add a custom user field.

Create an initializer config/initializers/custom_user_fields.rb

Decidim::CustomUserFields.configure do |config|
  config.add_field :birthdate, type: :date, required: true
  config.add_field :address, type: :textarea, required: false, rows: 10
  config.add_field :purpose, type: :text, required: false
end

Available field types

:date

parameters:

• required: must choose a date
• not_before: date in ISO8601 where the user cannot select before
• not_after: date in ISO8601 where the user cannot select after
• skip_hashing: Do not hash the field result (watch out privacy concerns)

:textarea a textarea field, which the content will be trimmed (no whitespaces before and after).

parameters:

• required: if the field is required
• min: minimal text length
• max: maximal text length
• skip_hashing: Do not hash the field result (watch out privacy concerns)
• ui.rows: how many rows the field should display

:text a text field, which the content will be trimmed (no whitespaces before and after).

parameters:

• required: if the field is required
• values_in: restrict the values accepted for the field
• format: a regex (like `format: /\A[A-z0-9]*\z/)
• skip_hashing: Do not hash the field result (watch out privacy concerns)

:extra_field_ref (Authorization only)

This field is a quiet special one, it allows workflows where the extra_field on registration is optional, but get required on authorization. Warning: this field can be use only in authorization configuration

parameters:

• ref: the extra_field reference name
• hide_if_value: hide the extra field if there is already a value.
• skip_hashing: Do not hash the field result (watch out privacy concerns)
• skip_update_on_verified: Do not update the extra_field reference when verified
• ...: any other parameters to override the reference option

Labels

Labels are translated and are under the translation scope decidim.custom_user_fields. Example of a config/locales/fr.yml file:

fr:
  decidim:
    authorization_handlers:
      pb2024:
        name: "Données de rescencement pour le Budget Participatif 2024"
        explanation: "Donnée récoltée pour participer au BP 2024"
    custom_user_fields:
      extended_data:
        first_name:
          label: "Prénoms"
        last_name:
          label: "Nom de famille"
      pb2024:
        birthdate:
          label: "Date de naissance"
          help_text: "La participation est réservée aux personnes de plus de 18ans"
        postal_code:
          label: "Code postal"
          help_text: "La participation est réservée aux habitants de MaCommune.

Create an authorization with custom fields

# Fields added to the profile
Decidim::CustomUserFields.configure do |config|
  config.add_field :first_name, type: :text, required: false
  config.add_field :last_name, type: :text, required: false
end

# Fields for the verification PB2024
Rails.application.config.after_initialize  do
  Decidim::CustomUserFields::Verifications.register("PB2024") do |config|
    config.add_field :first_name, type: :extra_field_ref, required: true, skip_hashing: true, hide_if_value: true
    config.add_field :last_name, type: :extra_field_ref, required: true, skip_hashing: true, hide_if_value: true
    config.add_field :birthdate, type: :date, required: true, not_after: 18.years.ago.to_date.iso8601
    config.add_field :postal_code, type: :text, required: true, format: /\A[\-0-9]*\z/, values_in: ["2000", "2001", "2002"]
  end
end

Then, add locales for this flow:

fr:
  decidim:
    authorization_handlers:
      pb2024:
        name: "Participer au BP 2024"
        explanation: "Valider votre compte"
    custom_user_fields:
      first_name:
        label: Prénoms
        help_text: Ce champs est requis pour participer aux budgets participatif.
      last_name: 
        label: Nom de famille
    pb2024:
      birthdate:
        label: Date de naissance
        bad_not_after: Seul les > 18 peuvent participer
      postal_code:
        label: Code postal
        bad_values: Ce code postal est inconu dans  maCommune
        help_text: Seul les communies prêt de maCommune peux être acceptée

Run locally

To run this module locally, we use Docker-compose:

docker-compose up

This will run a decidim-user_fields container, which sleeps and does nothing.

After your containers are mounted, you can seed the database:

  docker-compose exec -it decidim-user_fields bin/rails db:seed

Then, you can start the server

  docker-compose exec -it decidim-user_fields bin/rails s -b 0.0.0.0

You can then open a bash session and edit the initializer, as described in the "How to add a custom user field" section.

  docker-compose exec -it decidim-user_fields bash

Once something change, reset your server:

  docker-compose exec -it decidim-user_fields bin/rails restart

While developing locally, you have two environment variables that can help you:

• ROOT: the root of the application using the module
• MODULE_ROOT: the place where your gem code is.
