How to use OpenStruct In Ruby
OpenStruct is a Ruby standard library that provides a data structure similar to a Hash but with the ability to access keys as attributes.
Syntax:
require ‘ostruct’
object = OpenStruct.new(hash)
Example:
In this example, we create an OpenStruct object person from a hash containing information about a person. We can then access the attributes of the person object using dot notation, making the code more readable.
require 'ostruct'
# Hash containing person information
person_hash = { name: 'John', age: 30, city: 'New York' }
# Convert hash to object using OpenStruct
person = OpenStruct.new(person_hash)
# Accessing attributes of the object
puts "Name: #{person.name}"
puts "Age: #{person.age}"
puts "City: #{person.city}"
Output
Name: John Age: 30 City: New York
How to convert Hash to Object in Ruby?
In this article, we will discuss how to convert a hash to an object in Ruby. Converting hash to an object allows one to access hash keys as object attributes, providing them with a more intuitive way to work with data.
