Ruby Client for REST API

This file implements a simple Ruby client library for using Parse's REST API. Rather than try to implement an ActiveRecord-compatible library, it tries to match the structure of the iOS and Android SDKs from Parse.

So far it supports simple GET, PUT, and POST operations on objects. Enough to read & write simple data.


This currently depends on the gems 'json' and 'patron' for JSON support and HTTP, respectively.

Getting Started

To get started, load the parse.rb file and call Parse.init to initialize the client object with your application ID and API key values, which you can obtain from the dashboard.

Parse.init :application_id => "<your_app_id>",
           :api_key        => "<your_api_key>"

Creating and Saving Objects

Create an instance of Parse::Object with your class name supplied as a string, set some keys, and call save().

game_score = "GameScore"
game_score["score"]         = 1337
game_score["playerName"]    = "Sean Plott"
game_score["cheatMode"]     = false

Alternatively, you can initialize the object's initial values with a hash.

game_score = "GameScore", {
    "score" => 1337, "playerName" => "Sean Plott", "cheatMode" => false

Or if you prefer, you can use symbols for the hash keys - they will be converted to strings by Parse::Object.initialize().

game_score = "GameScore", {
        :score => 1337, :playerName => "Sean Plott", :cheatMode => false

Retrieving Objects

Individual objects can be retrieved with a single call to Parse.get() supplying the class and object id.

game_score = Parse.get "GameScore", "xWMyZ4YEGZ"

All the objects in a given class can be retrieved by omitting the object ID. Use caution if you have lots and lots of objects of that class though.

all_scores = Parse.get "GameScore"


Queries are supported by the Parse::Query class.

# Create some simple objects to query
(1..100).each { |i|
  score = "GameScore"
  score["score"] = i

# Retrieve all scores between 10 & 20 inclusive"GameScore")   \
  .greater_eq("score", 10)      \
  .less_eq("score", 20)         \

# Retrieve a set of specific scores"GameScore")           \
  .value_in("score", [10, 20, 30, 40])  \
