Acts As Featureable

Build Status

Requires ruby 1.9.3 or later

Add a polymorphic resource to your rails app for pulling content to a main/features page.

Installation

Add this line to your application's Gemfile:

gem 'acts_as_featureable'

And then execute:

$ bundle

Or install it yourself as:

$ gem install acts_as_featureable

Run the generator:

$ rails g features

This will create the migration file and an initializer.

Migrate the database:

$ rake db:migrate

Configuration

Edit the initializer file to set default settings for feature size and auto title & summary assigning:

Usage

Featureable Model

Add the appropriate line to the class you want to feature:

class Topic
	acts_as_featurable
end

Add the routes to your routes config file for the resource(s) you wish to make featureable

resources :topics do
	resources :features
end

CanCan integration

If you are using CanCan for authorization, the features controller will automatically add authorization to each action.

Creating Features

Add a feature to a model. The title and summary (or whichever methods you add in the initializer file) will be assigned:

featureable = Topic.create(title: 'Title', summary: 'Summary')
featureable.features.create
# => <Feature title: "Title", summary: "Summary">

You can also override them directly:

featureable = Topic.create(title: 'Title', summary: 'Summary')
featureable.features.create(title: 'My New Title', summary 'My New Summary')
# => <Feature title: "My New Title", summary: "My New Summary">

The position of the features can be specified:

featureable = Topic.create
featureable.features.create(position: 3)
# => <Feature position: 3>

If it is not specified, it will automatically be assigned the next, lowest position:

featureable = Topic.create
featureable.features.create
# => <Feature position: 1>

featureable.features.create
# => <Feature position: 2>

If you try and assign a position which has already been taken, it will find the next, lowest available position:

featureable = Topic.create
featureable.features.create
# => <Feature position: 1>

featureable.features.create(position: 1)
# => <Feature position: 2>

featureable.features.create(position: 1)
# => <Feature position: 3>

Categories

You can specify categories when creating features:

featureable = Topic.create
featureable.features.create(category: :mains)
# => <Feature category: "mains">

You can specify any category and as many as you like to pull to different parts of your site.

featureable = Topic.create
featureable.features.create(category: :mains)
# => <Feature category: "mains">
featureable.features.create(category: :hot_topics)
# => <Feature category: "hot_topics">

featureable.features.count
# => 2

featureable.features.where(category: :hot_topics).count
# => 1

This is the default behaviour. If you specify categories in your acts_as_featureable.rb initilaizer file:

config.categories = [:mains, :hot_topics]

then these are the only allowable categories for your application. You also get the side benefit of having a scope created for each of these categories on the Feature class. See the next section for more details.

Feature scope

Get all features ordered by thier position ascending:

Feature.ordered

If you have specified strict categories in your initializer (see previous section) then you can use those as scopes on the Feature class:

Feature.hot_topics
# => <Feature category: "hot_topics" ... >

View Helpers

Adds two helper methods to your views:

<%= feature_form_for(featureable) %>

Which renders a basic form for creating features from a featureable object.

<%= features_for(featureable) %>

Which simiply lists the features' position and category with a delete link
