metahash's Introduction

MetaHash

Provides a subclass of Hash and a wrapper around Rails' serialize attribute for object-like access to hashes without validating existence of nested hashes

Examples

Access nested hashes using method / object syntax

h = Metadata.new
h # => {}
h.outer.inner # => {}

Access to values stored in nested hashes via method call syntax

h = Metadata.new( { outer: { inner: { hash_key: "value" } } } )
h.outer.inner.hash_key # => "value"

Set values for nested hash structures without the nested hashes having to be initially defined

h = Metadata.new( {} )

Using with ActiveRecord

In your Gemfile

gem "metahash", github: "TinderBox/MetaHash"

in your ActiveRecord model

metadata_field_for :field_name

Support

This gem has been tested with Ruby 2.0, and rails 3.2

metahash's Issues

Don't set the field to have nested empty hashes unless explicitly told to do so.

Desired behavior:

metadata = Metadata.new
metadata.data.should be_nil
metadata.data.nested_data.should be_nil
metadata.should == {}
metadata.data = {}
metadata.should == {data: {}}

Current Behavior:

metadata = Metadata.new
metadata.data == {}
metadata.data.nested_data == {}
metadata == {data: {nested_data: {}}

this is a problem if one of the nested keys we call is eventually supposed to be a non Hash

example:

metadata = Metadata.new
id = metadata.property.id
klass.find(id)

=> errors cause id is a hash, rather than an id or nil
