Generate Active Admin Comment during a Action

Question

How can I use Ruby/Rails code to generate an ActiveAdmin comment - such as during a controller action, or in an ActiveRecord lifecycle callback? (For example, when I change the status of a Order record from 'closed' to 'open'.)

Answer 1

Let say you have a User model, and you want to create a comment to a particular user.

in model:

after_update :add_comment

 def add_comment 
  ActiveAdmin::Comment.create(
    resource_id: User.last.id, # id of that particular user to which you add comment
    namespace: 'admin',
    body: 'Your comment body',
    resource_type: 'User',
    author_id: 1, # id of the comment's author, could be AdminUser.first, for example
    author_type: 'AdminUser'
  )
end
