# Works Cited
Works Cited allows you to add a list of the works cited in ActiveRecord objects, to be formatted by a helper that can be added to relevant pages to format the citations like a bibliography.

Works Cited uses CanCanCan to authorize the editing of citations. This makes it easy for you to control access.

## Installation
Add this line to your application's Gemfile:

```ruby
gem 'works_cited'
```

And then execute:
```bash
$ bundle install
```

Then generate the migrations
```bash
$ rails g works_cited:install
$ rake db:migrate
```

## Configuration

You will need to add access for the people who should be authorized. Works Cited uses CanCanCan for authorization. Simply add the appropriate permissions to your ability.rb file:

```ruby
class Ability
  include CanCan::Ability

  def initialize(user)
    user ||= User.new

    can :list, WorksCited::Citation
    can :list, WorksCited::Contributor

    return if user.new_record? # Anonymous Users leave

    can :read, WorksCited::Citation
    can :read, WorksCited::Contributor
    # # We could have other rules in here, like:
    # can :manage, WorksCited::Citation, record: { user_id: user.id }
    # can :manage, WorksCited::Contributor, record: { user_id: user.id }

    return unless user.admin? # Non Admin Users leave

    can :select, :all
    can :manage, WorksCited::Citation
    can :manage, WorksCited::Contributor
  end
end
```

You may wish to add custom contributor roles or citation types. To do that, add something like the following to `config/initializers/works_cited.rb`:

```ruby
WorksCited.configure do |config|
  # This will dynamically generate a scope (.astrologians) and a boolean check (#astrologian?)
  # on WorksCited::Contributor
  config.valid_contributor_roles << 'astrologian'

  # This will dynamically generate a scope (.star_charts) and a boolean check (#star_chart?)
  # on WorksCited::Citation
  #
  # If you want to override the default view for any new (or existing) types:
  # List a citation: app/views/works_cited/citation_types/citation/_star_chart.html.[haml/erb]
  # Add/Edit a citation: app/views/works_cited/citation_types/fields/_star_chart.html.[haml/erb]
  config.valid_citation_types << 'star_chart'
end
```

## Usage
Make a model ready to accept citations

```ruby
has_works_cited
```

Add the helpers to the relevant views

```haml
= works_cited_list @record
```

## Contributing
* Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
* Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
* Fork the project.
* Start a feature/bugfix branch.
* Commit and push until you are happy with your contribution.
* Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
* Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
