Refactor to Helpers

This Rails partial is almost all template escapes. Put it into a helper, and refactor each case to methods so we can build out the controls for each. (I've converted to tabs - fighting with Vimgolf's default config shouldn't be part of the challenge.)

Start file

## _controls.html.erb
<div class='controls'>
	<% if event.author == current_user -%>
		<%= link_to "Edit Activity", edit_event_path(event), :class => 'button' %>
	<% else -%>
		<% if current_user.attending? event -%>
			<%= link_to "Leave", leave_event_path(event), :class => "button neg", :method => :post %>
		<% else -%>
			<% if current_user.invited_to? event -%>
				<%= link_to "Accept Invite", join_event_path(event), :class => "button pos", :method => :post %>
			<% else -%>
				<%= link_to "I'm Going", join_event_path(event), :class => "button pos", :method => :post %>
			<% end -%>
		<% end -%>
	<% end -%>
</div>

## event_helper.rb
module EventHelper
end

End file

## _controls.html.erb
<div class='controls'>
	<%= event_controls event %>
</div>

## event_helper.rb
module EventHelper
	def event_controls(event)
		if event.author == current_user
			author_controls(event)
		elsif current_user.attending? event
			attendee_controls(event)
		elsif current_user.invited_to? event
			invitee_controls(event)
		else
			public_controls(event)
		end
	end

	def author_controls(event)
		link_to "Edit Activity", edit_event_path(event), :class => 'button'
	end

	def attendee_controls(event)
		link_to "Leave", leave_event_path(event), :class => "button neg", :method => :post
	end

	def invitee_controls(event)
		link_to "Accept Invite", join_event_path(event), :class => "button pos", :method => :post
	end

	def public_controls(event)
		link_to "I'm Going", join_event_path(event), :class => "button pos", :method => :post
	end
end
