avvo/easygoing_active_model

An ActiveModel::Model that does not raise exceptions when you pass a parameter for something undefined.

EasygoingActiveModel

ActiveModel::Model will raise an error if you try to pass in a value that it does not have a setter for. This version of it just skips over such params.

For example, imagine the following client class, used in association with any API:

class ClientClass
    include ActiveModel::Model

    attr_accessor :my_variable_1
    attr_accessor :my_variable_2

end

Some controller might have this:

ClientClass.new(params)

Or some parent class might do a similar thing:

class ClientClassParent

    def initialize(params = {})
        @child_class = ClientClass.new(params[:child_class])
    end

end

Either way, it is possible the hash being passed in to instantiate ClientClass has some parameter other than :my_variable_1 or :my_variable_2. If it does, we'll get an exception.

Installation

Add this line to your application's Gemfile:

gem 'easygoing_active_model'

And then execute:

$ bundle

Or install it yourself as:

$ gem install easygoing_active_model

Usage

Just include EasygoingActiveModel::Model instead of ActiveModel::Model.

class ClientClass
    include EasygoingActiveModel::Model

    attr_accessor :my_variable_1
    attr_accessor :my_variable_2

end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake false to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
