rails_admin_aasm

Rails Admin State Machine

Properly manage AASM states from rails_admin

Allows easily sending state_machine events to a model from Rails Admin, including support for ActiveRecord \ Mongoid and custom state field name and multiple state machines per model.

Based on https://github.com/rs-pro/rails_admin_state. Since state_machine currently is not maintained, I turn to AASM https://github.com/aasm/aasm.

Installing

Add this line to your application's Gemfile:

#please use `0.1.1` if rails_admin <= `0.8.1`
gem 'rails_admin_aasm'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_admin_aasm

Usage

Add the state action:

RailsAdmin.config do |config|
  config.actions do
    ......
    state
  end
end

Mark the field you need display as state:

rails_admin do
  list do
    field :state, :state
    ...
  end
  edit do
    field :state, :state
    ...
  end
  ...
end

States and event button/label custom classes:

rails_admin do
  list do
    field :state, :state
    ...
  end
  ...
  state({
    events: {dead: 'btn-danger', drain: 'btn-warning', alive: 'btn-success'},
    states: {dead: 'label-important', drain: 'label-warning', alive: 'label-success'}
    disable: [:dead] # disable some events so they are not shown.
  })

end

Some classes are preset by default (published, deleted, etc)
