Status Assignable

Installation

Add this line to your application's Gemfile:

gem 'status_assignable', '~> 0.1'

Usage

Model

In your model, add the following line:

class ModelName < ApplicationRecord
  include StatusAssignable
  # or
  has_assignable_status

  # ...
end

Then add a new migration that will add a status column to the model's database table:

rails g migration AddStatusToModelName

class AddStatusToModelName < ActiveRecord::Migration[<RAILS VERSION>]
  def change
    add_column :model_names, :status, :integer, default: 1
    # 0 = deleted, 1 = active, 2 = inactive
  end
end

Your model is now status assignable!

my_model = ModelName.find(1)
my_model.inactive! # Set the status to inactive
my_model.inactive? # true
my_model.deleted! # Set the status to deleted
my_model.deleted? # true
my_model.active! # Set the status to active
my_model.active? # true
my_model.soft_destroy # Archive the record with callbacks and its associations
my_model.archive # Alias of soft_destroy
my_model.soft_delete # Directly update the column in the database and also update its associations

Custom Status

You can also add your own status if need be. For example, if you want to add a pending status:

class ModelName < ApplicationRecord
  include StatusAssignable[pending: 3]
  # or...
  has_assignable_status pending: 3

  # ...
end

This will add a pending status for your model. You can then use it like so:

my_model = ModelName.find(1)
my_model.pending! # Set the status to pending
my_model.pending? # true

Take note that the application will raise an exception if the default statuses are overridden. Use different key-value pair for your custom status if that happens.

Associations

Model associations are also supported. For example, if you have a User that has many Posts and Comments, you can add the following line to the User model:

class User < ApplicationRecord
  has_assignable_status

  has_many :posts, dependent: :destroy, archive: :callbacks
  has_many :comments, dependent: :delete_all, archive: :assign
end

The archive option can be set to :callbacks or :assign. If set to :callbacks, the associated records will be archived using soft_destroy. If set to :assign, the associated records will have their status columns assigned directly.

It is important that the associations also are StatusAssignable!

Callbacks

Callbacks are only fired when archive or soft_destroy is called. soft_delete never fires callbacks (the association will use callbacks if it has the archive: :callbacks option).

There are callback hooks supported for soft_destroy: before_soft_destroy, around_soft_destroy, after_soft_destroy. They work like any model callbacks, so use them if need be when archiving a record.

class Post < ApplicationRecord
  has_assignable_status

  before_destroy -> { versions.destroy_all }
  before_soft_destroy :update_and_unlink_versions
end
