Callbacks

{% hint style="info" %} This section is based on Granite's README {% endhint %}

There is support for callbacks on certain events.

Here is an example:

require "granite_orm/adapter/pg"

class Post < Granite::ORM
  adapter pg

  before_save :upcase_title

  field title : String
  field content : String
  timestamps

  def upcase_title
    if title = @title
      @title = title.upcase
    end
  end
end
