JSON Schema Builder

Build Status

Build a JSON schema for your ActiveRecord models. STOP your API pains!

The created schema.json files are meant as stubs and need to be enriched with field descriptions and names. You might also want to remove or add object properties, since the gem only uses the available ActiveRecord database fields.


Hook the gem into your rails app and create the schema files. rake re gem 'json_schema_builder' rake schema:build

Your Models and their fields are written into JSON files which you can pimp further.
