Included in:

Defined in:
lib/opt_ar/helpers/method_finder_helper.rb

Overview

Methods for handling all attributes read

Constant Summary collapse

ID_STRING = 
'id'.freeze
WARN_MSG = 
'WARNING :: Trying to access attr that was not requested'.freeze
DEFAULT_DATE_TIME_ATTRIBUTES = 
%i[created_at updated_at].freeze
DATE_TIME_CONST_KEY = 
'DATE_TIME_ATTRIBUTES'.freeze

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *args) ⇒ Object (private)

Checks for attribute from the attributes hash and returns if found

Overriding to avoid attributes misses from causing an error It just throws a warning and proceeds with fetching the actual

ActiveRecord object,to check for it's response to the method
defined by name method_name

Provided only as a fallback for the worst case scenario. Avoid calling

methods on the instance, for attribute that was not requested initially

Raises:
