h2. WHAT

Given a bunch of ruby Hash, an ActiveRecord model class and a unique key, DataPatcher creates a Hash of the differences between the bunch of Hash and the table.

Have a look at the (very simple) spec/data_patcher.rb to get a better understanding of what's possible.

h2. REAL-LIFE USE

This is useful if you are aggregating various data sources and what to have a good level of control on what is added or modified. I do that on "Learnivore.com":http://www.learnivore.com and for some of my clients data processing.

When doing this, I tend to parse all the sources again, compare the result to already registered data, and see what are the differences and if they should be applied.

h2. TEST

Edit spec/database.yml and run rake spec.

Test data is recreated automatically when running rake spec.

h2. IDEAS

* find another name - I don't like DataPatcher

* find a better Hash patch format

** move the key outside the diff Hash ?

* support removed records ? (I don't need that for the moment)

* add some way to apply the patch directly inside DataPatcher ?
