dm-filemaker-adapter

A Filemaker adapter for DataMapper, allowing DataMapper to use Filemaker Server as a datastore.

dm-filemaker-adapter uses the ginjo-rfm gem as the backend command and xml parser. Ginjo-rfm is a full featured filemaker-ruby adapter that exposes most of Filemaker's xml interface functionality in ruby. dm-filemaker-adapter doesn't tap into all of rfm's features, but rather, it provides DataMapper the ability to use Filemaker Server as a backend datastore. Most of the basic functionality of DataMapper's interface is supported, including compound queries and 'or' queries (using Filemaker's -findquery command), validations, associations, query operators like :field.gt=>something, lazy-loading where possible, first & last record, aggregate queries, ranges, field mapping, and more.

Installation

gem 'dm-filemaker-adapter'

And then execute:

$ bundle

Or install it yourself as:

$ gem install dm-filemaker-adapter

Usage

# ruby

DB_CONFIG = {
  adapter:            'filemaker',
  host:               'my.server.com',
  account_name:       'my-user-name',
  password:           'xxxxxxxxxx',
  database:           'db-name'   
}

DataMapper.setup(:default, DB_CONFIG)

class User
  include DataMapper::Resource

  # Name the filemaker layout representing the table you're modeling.
  storage_names[:default] = 'user_xml'  

  # Property & field names are case-sensitive.
  property :id, Serial
  property :username, String, :length => 128, :unique => true, :required => true,
    :default => lambda {|r,v| r.instance_variable_get :@email}
  property :email, String, :length => 128, :unique => true, :required => true, :format=>:email_address
  property :updated_at, DateTime, :field=>'ModifiedAtTimestamp'
  property :encrypted_password, BCryptPassword

  has n, :orders
end

class Order
  include DataMapper::Resource
  storage_names[:default] = 'order_xml'

  property :id, Serial
  property :user_id, Integer
  property :status, String

  belongs_to :user
end

DataMapper.finalize



# create record
  user = User.create(:email => 'abc@company.com', :username => 'abc')

# create associated record
  user.orders.new(:status=>'draft')

# get a specific user id
  User.get '1035'

# first record that matches exactly 'name'
  User.first :username => 'name'

# all records updated since 3 days ago
  User.all :updated.gt => Time.now-3*24*60*60

# records 10 thru 20, ordered by :id (the range is resolved by filemaker, before records are returned!)
  User.all(:order => :id)[10..20]

# filter associated records
  user.orders.all(:status=>'closed')

# use the union operator to create 2 find requests in a filemaker 'OR' operation
  User.all(:email => 'abc@company.com', :activated_at.gt => '1/1/1980') | \
  User.all(:username => 'abc', :activated_at.gt => '1/1/1980')

# which gets translated to the filemaker query
    User.find [
      {:email => 'abc@company.com', :activated_at => '>1/1/1980'},
      {:username => 'abc', :activated_at.gt => '>1/1/1980'}
    ]

# use the intersection operator to combine multiple search criteria in a filemaker 'AND' operation
  User.all(:email => 'abc@company.com', :activated_at.gt => '1/1/2015') & \
  User.all(:email => 'abc@company.com', :activated_at.lt => '5/1/2015')

# you can also write this as
  User.all(:email => 'abc@company.com', :activated_at.gt => '1/1/2015', :activated_at.lt => '5/1/2015')

# both of the above get translated to the filemaker query
    User.find(:email => 'abc@company.com', :activated_at => '>1/1/2015 <5/1/2015')
