Hashash
Hashash is a collection of classes and mixins that make it more useful when working with JSON APIs. Convert underscore to camelcase, convert camelcase to underscore, convert hashes to the objects.
Installation
Add this line to your application's Gemfile:
gem "hashash"
And then execute:
$ bundle
Or install it yourself as:
$ gem install hashash
Underscore keys when working with JSON APIs
underscore_keys
converts all keys in a hash to underscore.
hash = { firstName: "Surim", lastName: "Kim" }
hash.underscore_keys
# => {:first_name=>"Surim", :last_name=>"Kim"}
deep_underscore_keys
recursively converts all keys in a hash to underscore.
hash = { person: { firstName: "Surim", lastName: "Kim" } }
hash.deep_underscore_keys
# => {:person=>{:first_name=>"Surim", :last_name=>"Kim"}}
Camelize keys when working with JSON APIs
camelize_keys
converts all keys in a hash to camelcase.
lowerCamelCase
hash = { first_name: "Surim", last_name: "Kim" }
hash.camelize_keys
# => {:firstName=>"Surim", :lastName=>"Kim"}
UpperCamelCase
hash = { first_name: "Surim", last_name: "Kim" }
hash.camelize_keys(:upper)
# => {:FirstName=>"Surim", :LastName=>"Kim"}
deep_camelize_keys
recursively converts all keys in a hash to camelcase.
lowerCamelCase
hash = { person: { first_name: "Surim", last_name: "Kim" } }
hash.deep_camelize_keys
# => {:person=>{:firstName=>"Surim", :lastName=>"Kim"}}
UpperCamelCase
hash = { person: { first_name: "Surim", last_name: "Kim" } }
hash.deep_camelize_keys(:upper)
# => {:Person=>{:FirstName=>"Surim", :LastName=>"Kim"}}
Converts hashes to the objects.
objectified_hash
hash = { person: { first_name: "Surim", last_name: "Kim" } }
objectified_hash = Hashash::ObjectifiedHash.new(hash)
# => #<Hashash::ObjectifiedHash:70188137990700 {hash: {:person=>{:first_name=>"Surim", :last_name=>"Kim"}}}
puts objectified_hash.person
# => #<Hashash::ObjectifiedHash:70188137990400 {hash: {:first_name=>"Surim", :last_name=>"Kim"}}>
puts objectified_hash.person.first_name
# => "Surim"
Development
After checking out the repo, run bin/setup
to install dependencies. Then, run rake test
to run the tests. You can also run bin/console
for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install
. To release a new version, update the version number in version.rb
, and then run bundle exec rake release
, which will create a git tag for the version, push git commits and tags, and push the .gem
file to rubygems.org.
