Validate() is run always before one of the more specific validation methods

I did not see this mentioned explicitly anywhere.

The method validate is run always before a call to validate_on_create or validate_on_update is made.

Example:

class Foo < ActiveRecord::Base
  def validate
    puts 'In validate'
  end

  def validate_on_create
    puts 'In validate_on_create'
  end

  def validate_on_update
    puts 'In validate_on_update'
  end
end

Now, when creating a new Foo using script/console, the output is as follows:

In validate
In validate_on_create

and when updating a Foo, the output looks like:

In validate
In validate_on_update
