This is my personal library I use to share the Ruby tidbits I made it for my various projects


Add this line to your application's Gemfile:

gem 'ruby-tidbits', git: 'https://github.com/konoplev-roman/ruby-tidbits'

And then execute:

$ bundle



To use bool extensions, add to the top of your file:

require 'tidbits/bool'

You can now use

  • .to_bool on NilClass, String, Numeric, FalseClass and TrueClass
  • .to_i for FalseClass and TrueClass


nil.to_bool# => false

'yes'.to_bool# => true

'no'.to_bool# => false

1.to_bool# => true

0.to_bool# => false

false.to_bool# => false

false.to_i# => 0

false.to_bool# => true

true.to_i# => 1


Add to the top of your file:

require 'mysql2'
require 'tidbits/mysql2'

This code provides a set of extensions to the mysql2 Rubygem.

  • The result of the query is returned as an array.
  • The exception is returned with the sql query that caused the error.


# when valid sql
database.query 'SELECT * FROM users;'# => [{ ... }, { ... }]

# when invalid sql
database.query 'SELECT * FROM user;'# => Mysql2::Error (Table 'user' doesn't exist; SQL: SELECT * FROM user;)

Symbolize keys

Add to the top of your file:

require 'tidbits/symbolize_keys'

Recursive converts the keys of the hash to symbols


{ 'foo' => { 'bar' => { 'baz' => 1 } } }.symbolize_keys# => { :foo => { :bar => { :baz => 1 } } }
