Prairie

Prairie is a Rails 4.0 app that demonstrates the use of the Redis key value store to implement dynamic custom fields. Prairie relies on the redis-objects gem for much of the interaction with Redis. Its architecture addresses potential situations where a user might want to create dozens, or perhaps hundreds, of custom fields.

Dynamic custom fields

• Multiple field types including string, numeric, select list, radio button and checkbox
• Custom field grouping and sequencing: within groups, custom fields are sequenced using the Ranked-Model gem
• Custom field validation including string length and numerical limits

Search

What is the point of creating custom fields without the ability to search them? Prairie provides by-relevance search that orders search results in 3 groups:

• Exact match of all search terms, including core and custom fields
• Exact match of any search term
• Near match of all search terms, with 'substring' matching of string fields and 'within range' matching of numeric fields

Code quality

• Test coverage: full Rspec coverage and reporting with the Simplecov gem
• Acceptance testing features with the Capybara gem
• Redis configuration explicitly defined; see dvlp_9212.conf or test_6379.conf
• Pagination: with the Kaminari gem
• Decorators: with the Active Decorator gem
• Global settings with the Settingslogic gem
• Styling: with Twitter Bootstrap

Setup

Prairie requires PostgreSQL and Redis. With Ruby 1.9.3 or later and gem bundler installed:

bundle install
bundle exec rake db:create:all
bundle exec rake db:migrate
redis-server ./config/redis/dvlp_9212.conf
rails s

Why 'Prairie'

A prairie suggests an expanse of meadows, full of diverse fields and wildlife.
