Define table structure (columns and indexes) inside your ActiveRecord models like you can do in migrations. Also similar to DataMapper inline schema syntax.
Specify columns like you would with ActiveRecord migrations and then run .auto_upgrade! Based on the mini_record gem from Davide D'Agostino, it adds fewer aliases, doesn't create timestamps and relationship columns automatically.
You don't have to be connected to the database when you run the DSL methods.
Over 2 years in Brighter Planet's environmental impact API and reference data service.
Lots and lots of use in the
class Breed < ActiveRecord::Base col :species_name col :weight, :type => :float col :weight_units end Breed.auto_upgrade! class Airport < ActiveRecord::Base self.primary_key = "iata_code" belongs_to :country, :foreign_key => 'country_iso_3166_code', :primary_key => 'iso_3166_code' col :iata_code col :name col :city col :country_name col :country_iso_3166_code col :latitude, :type => :float col :longitude, :type => :float end Airport.auto_upgrade! class ApiResponse < ActiveRecord::Base # store with: self.raw_body = Zlib::Deflate.deflate(body, Zlib::BEST_SPEED) # retrieve with: Zlib::Inflate.inflate(raw_body).force_encoding 'UTF-8' # just an idea! col :raw_body, :type => 'varbinary(16384)' end ApiResponse.auto_upgrade! # you can also do this ApiResponse.auto_upgrade! :dry_run => true # this won't delete columns that it doesn't know about ApiResponse.auto_upgrade! :gentle => true
Massive thanks to DAddYE, who you follow on twitter @daddye and look at his site at daddye.it
- make the documentation as good as mini_record
- investigate switching back to ActiveRecord::ConnectionAdapters::TableDefinition as a way of holding column and index info
mini_record version v0.2.1 - thanks @daddye! See CHANGELOG for a rough outline of the differences.
