FormalWear

"You're going to like the way you look. I guarantee it."

FormalWear helps you create Form Objects with required and optional attributes and gets all fancy widdit.

Installation

Add this line to your application's Gemfile:

gem 'formal_wear'

And then execute:

$ bundle

Or install it yourself as:

$ gem install formal_wear

Usage

class TestFormalWear
  include FormalWear

  required_attr moms_id: {
    name: "Your mom's id",
    type: :text,
    source: ->(s) { s.primary.thing_to_be_configured },
  }

  required_attr docs_id: {
    name: "Your doc's id",
    type: :text,
    source: ->(s) { s.primary.dependent_object.another_thing_to_be_configured },
    store: :set_my_docs_id
  }

  required_attr lambda_lambda_lambda: {
    name: 'Revenge Of The Nerds!',
    type: :text,
    source: ->(s) { s.get_pledged },
    store:  ->(s) { s.got_lambda? }
  }

  protected

  def after_save
    # no-op
  end

  def set_moms_id
    # no-op
  end

  def set_my_docs_id
    # no-op
  end

  def got_lambda?
    # no-op
  end

  def get_pledged
    primary.dependent_object.another_thing_to_be_configured
  end
end

Including FormalWear into your class adds a required_attrs and required_attr methods. Specifying a required attr, like so:

  required_attr lambda_lambda_lambda: {
    name: 'Revenge Of The Nerds!',
    type: :text,
    source: ->(s) { s.get_pledged },
    store:  ->(s) { s.got_lambda? }
  }

adds the attribute to the list of required_fields, and populates it from the source specified in its hash when your class is initialized.

Instantiating

  TestFormalWear.new(primary_object)

... where primary object you will use to fetch values from their source. (TODO: add support for multiple sources)

Specifying sources

The source option takes a lambda that accepts self as its argument. This allows you to use a method within your class to fetch the information needed from its source, or to directly fetch it using the primary object set when you instantiated the class.

Source is a required attribute, but it can return nil if you feel so inclined. It's a bit like going commando under that tuxedo, though.

TODO

• Update this readme
• (Maybe?) Add helper methods for providing data for working with forms
