addressable_record¶ ↑

github.com/midas/addressable_record

Encapsulates the composed of pattern for addresses into any easy to use library.

• Store an address in multiple database fields, but load it as a AddressableRecord::Address object.

• Parse virtually any formatting an address can be represented with.

• Use 1 or more street address parts with no limit.

• Overrides #to_s with format strings to control output.

• Pre-defined named format strings to control output.

• Migration generator to generate a migration file containing the correct fields to hold the address data.

• geographer >= 1.1.1

• active_record >= 2.3

gem sources -a http://gemcutter.org
sudo gem install addressable_record

Add to environment file:

config.gem "addressable_record", :version => '~>1.0.0', :source => 'http://gemcutter.org'

Run:

sudo rake:gems:install

Generate a migration to add the necessary field to the database:

script/generate addressable_record_migration {file_name} {table_name} {field_name}
script/generate addressable_record_migration users_have_home_address users home_address

Will yield:

class UsersHaveHomeAddress < ActiveRecord::Migration
  def self.up
    add_column :users, :home_address_raw_street, :string, :limit => 255
    add_column :users, :home_address_city, :string, :limit => 50
    add_column :users, :home_address_state_or_province, :string, :limit => 50
    add_column :users, :home_address_raw_zip_code, :string, :limit => 9
    add_column :users, :home_address_country, :string, :limit => 75
  end

  def self.down
    remove_column :users, :home_address_raw_street
    remove_column :users, :home_address_city
    remove_column :users, :home_address_state_or_province
    remove_column :users, :home_address_raw_zip_code
    remove_column :users, :home_address_country
  end
end

Call the macro in an ActiveRecord descendant:

class User < ActiveRecord::Base
  address :home_address
end

Set the field equal to something:

@user.home_address = AddressableRecord::Address.new( 
  :raw_street => '123 Jones Street###Suite 540', 
  :city => 'Atlanta',
  :state_or_province => 'GA', 
  :raw_zip_code => '333331111', 
  :country => 'U.S.A.' )

or (with identical results):

@user.home_address = ['123 Jones Street', 'Suite 540', 'Atlanta', 'GA', '33333-1111']

Reference the raw database fields:

@user.home_address_raw_street                             # => 123 Jones Street###Suite 540
@user.home_address_city                                   # => Atlanta
@user.home_address_state_or_province                      # => GA
@user.home_address_raw_zip_code                           # => 333331111
@user.home_address_country                                # => U.S.A.

Reference the sub parts of the field:

@user.home_address.streets.first                          # => 123 Jones Street
@user.home_address.streets.join( ', ' )                   # => 123 Jones Street, Suite 540
@user.home_address.streets[1]                             # => Suite 540
@user.home_address.street                                 # => 123 Jones Street, Suite 540
@user.home_address.city                                   # => Atlanta
@user.home_address.state_or_province                      # => GA
@user.home_address.state                                  # => GA
@user.home_address.province                               # => GA
@user.home_address.zip_code                               # => 33333-1111
@user.home_address.zip_code_prefix                        # => 33333
@user.home_address.zip_code_ext                           # => 1111
@user.home_address.country                                # => U.S.A.

Use formats to control the output:

@user.home_address.to_s( '%s' )                           # => 123 Jones Street, Suite 540
@user.home_address.to_s( '%c' )                           # => Atlanta
@user.home_address.to_s( '%S' )                           # => GA
@user.home_address.to_s( '%z' )                           # => 33333-1111
@user.home_address.to_s( '%C' )                           # => U.S.A.
@user.home_address.to_s( '%c %S' )                        # => Atlanta GA

Use pre-defined named formats to control the output:

@user.home_address.to_s( :us_long )                       # => 123 Jones Street, Suite 540, Atlanta, GA 33333-1111 U.S.A.
@user.home_address.to_s( :us )                            # => 123 Jones Street, Suite 540, Atlanta, GA 33333-1111

• Fork the project.

• Make your feature addition or bug fix.

• Add tests for it. This is important so I don’t break it in a future version unintentionally.

• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

• Send me a pull request. Bonus points for topic branches.
