Rooftop::Rails::Events

A library to make it super-easy to integrate events from Rooftop CMS into your Rails site.

What's included

A bit of a mix of stuff, and all work in progress. Here's a flavour:

Controller Mixins

You need to include these yourself.

Rooftop::Rails::Events::EventHandler

A mixin for a controller which handles events. It has methods for show(), instances() and book_instance() which get the event from Rooftop for you.

In the simplest form, you can just include this in your controller

class EventsController < ApplicationController
    include Rooftop::Rails::Events::EventHandler
end

But each method yields to a block so you can do other stuff if you want. Here's a more representative EventsController from a real project:

class EventsController < ApplicationController
  include Rooftop::Rails::Events::EventHandler
  decorates_assigned :events, :event, with: EventDecorator
  layout :determine_layout

  def instances
    # Pass a block into the EventHandler mixin's method, which is yielded to at the end of the method
    super do
      # If the event has an external ticketing url, redirect to it instead of rendering a list of instances
      # n.b. pretty obviously you'll need to define has_external_ticketing_url?() and external_ticketing_url() on your model
      if @event.has_external_ticketing_url?
        redirect_to @event.external_ticketing_url and return
      end

      # If the event only has 1 instance, it seems a bit mean to list that instance and make the user click again; go straight to the book_instance method
      if @event.instances.count == 1
        redirect_to action: :book_instance, instance_id: @event.instances.first.meta_attributes[:spektrix_id] and return
      end

    end
  end

  private
  def determine_layout
    case action_name.to_sym
      when :show
        "templates/event_detail"
      when :instances
        "templates/instance_list"
      when :book_instance
        "templates/iframe_wide"
    end
  end
end

Model Mixins

These are included automatically when you use this gem.

Rooftop::Rails::Events::Cache

A mixin added to the Rooftop::Events::Event to cache / expire it.

### Rooftop::Rails::Events::InstanceCache The same as Rooftop::Rails::Events::Cache but for instances. Allows you to receive a webhook for just an instance and be able to clear the cache for its associated Event.

### Rooftop::Rails::Events::Scopes Handy scopes for dealing with events - finding after a date, between dates, in the future etc.

Object Decorators

We use a lot of Draper as our decorator pattern at Error Agency. So there are some mixins you add to your EventDecorator to provide utility methods for use in views.

#in your project
class EventDecorator < Draper::Decorator
    include Rooftop::Rails::Events::Decorators
end

## Controller mixin for Event collections The standard pattern we've found works well for Rooftop is to have a PagesController with mixins which check the template of the page you're rendering, and makes requests to get collections of objects you'll need.

class PagesController < ApplicationController
    include Rooftop::Rails::Events::EventCollections 
end

You get a bunch of stuff for free with this:

  • Rooftop events in the future will be returned as a collection called @events by default
  • if you pass in query params, you can filter these:
    • q will do a free-text search
    • from will take an dd-mm-yyyy date string and return things happening on or after that date
    • to will work likewise, in reverse

Customising querystring filters

You might want to filter by something else. That's relatively easy.

class PagesController < ApplicationController
    include Rooftop::Rails::Events::EventCollections
    self.add_event_filter :genre, ->(events,params) {
        # add something here which returns a collection when genre is passed in, for example
        # very important - you must return something here
        if params[:genre].present?
            events.with_genre(params[:genre])
        else
            events
        end
    }
end

Installation

Add this line to your application's Gemfile:

gem 'rooftop-rails-events'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rooftop-rails-events

Usage

TODO: Write usage instructions here

Development

After checking out the repo, run bin/setup to install dependencies. 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.
