Module: Mongoid::Extensions::Object::Checks

Included in:

Object

Defined in:

lib/mongoid/extensions/object/checks.rb

Overview

This module has object checks in it.

Instance Method Summary

• #_vacant? ⇒ true, false

  Since Active Support’s blank? check looks to see if the object responds to #empty? and will call it if it does, we need another way to check if the object is empty or nil in case the user has defined a field called “empty” on the document.

Instance Method Details

#_vacant? ⇒ true, false

Since Active Support’s blank? check looks to see if the object responds to #empty? and will call it if it does, we need another way to check if the object is empty or nil in case the user has defined a field called “empty” on the document.

Examples:

Is the array vacant?

[].vacant?

Is the object vacant?

nil.vacant?

Returns:

• (true, false) —

  True if empty or nil, false if not.

• 2.0.2
