RailsAdmin AuthorizedFields

This gem adds ability to setup authorization rules for fields in a simple way.

Installation

Add this line to your application's Gemfile:

gem 'rails_admin_authorized_fields'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_admin_authorized_fields

Configuration

Create initilializers/rails_admin_authorized_fields.rb:

RailsAdminAuthorizedFields.configure do |config|
  config.default_rule = proc { bindings[:view]._current_user.has_role?( :admin ) }
end

default_rule used when either authorized_fields or unauthorized_fields section included but rules for some fields are not specified.

Usage

Just add authorized_fields section to your model with specified rules:

rails_admin do
  authorized_fields( {
    [ :enabled, :is_default, :text_slug ] => proc { bindings[:view]._current_user.has_role?( :admin ) },
    [ :domain ] => proc { !bindings[:view]._current_user.has_role?( :manager ) },
  } )

  field :enabled
  field :name
  field :domain
  field :is_default
  field :text_slug
end

You can also use unauthorized_fields section in opposite of authorized_fields. All rules will be checked.

rails_admin do
  unauthorized_fields( {
    [ :enabled, :is_default, :text_slug ] => proc { bindings[:view]._current_user.has_role?( :manager ) },
  } )

  field :enabled
  field :name
  field :domain
  field :is_default
  field :text_slug
end

Note: all fields are not authorized by default if any rules present.

TODO: just a small changes needed to make authorized_fields section overridable in subsection (list, edit)
