A gem which handles multiple types of users on a rails app

#Acts as user

Acts as user handles multiple user roles on a rails app. It uses polymorphic associations to relate other models and behave like a user.

Getting started

ActsAsUser 1.2.1 works with rails 3 onwards. You can add it to your Gemfile with:

gem 'acts_as_user'

Then run the bundle command to install it.

After you install ActsAsUser you need to run the generator:

rails g acts_as_user:install

The generator will install in initializer which describes all the ActsAsUser configuration options, so we recommend you take a look at it. When you are done you are ready to start your user model:

rails g acts_as_user User <attributes>

Next you'll probably want to run the migrations "rake db:migrate", as the generator will create a migration file (open it modify if you need to).

##Configuration

For the models you want to inherit to you just have to add this line of code into them:

class Member
	acts_as_user
end

A little note on the User model...just in case!

class User
	is_user
end

###Ignore attributes to delegate from the user

If you want to ignore some attributes from your user model to the childs, you can do it on the acts_as_user.rb initializer like so:

ActsAsUser.setup do |config|
	config.ignored_attributes = ["name", "bio"]
end

By default it ignores the following attributes:

["created_at", "updated_at", "id", "userable_type", "userable_id"]

##Devise support

Yes we do!

Acts as a user plays well with Devise as it ignores and adds the corresponding attributes to delegate to.

When using devise, ActsAsUser will also ignore the encrypted_password attribute from the user. No further configuration needs to be done.

##Getting to know the user

ActsAsUser gem now adds some handy instance user methods that returns true or false wheter the current user is a specific type or not, for example:

A simple configuration may look something similar to:

class User < ActiveRecord::Base
 is_user
end

class Customer < ActiveRecord::Base
 acts_as_user
end

class Admin < ActiveRecord::Base
 acts_as_user
end

Just a little configuration is needed, you can do it on the acts_as_user.rb initializer like so:

ActsAsUser.setup do |config|
	config.models_acting_as_users = [:admin, :customer]
end

Now we will instantiate a Customer object:

customer = Customer.find(1)
current_user = customer.user

You now should be able to detect in this case if the current_user is wheter an admin or a customer by simply calling:

current_user.customer?
 => true
current_user.admin?
 => false

Enjoy!
