# Event Map Extension for Radiant This extension adds mapping to the [event_calendar](http://github.com/radiant/radiant-event-calendar-extension). It will geocode your events automatically based on the address of the venue, or you can supply a postal code, UK postcode or grid reference for greater precision. Events can be displayed on a google map and you can create links to bing or google maps that display the location of each event. ## Installation Should be straightforward: script/extension install event_map or as a gem: gem install radiant-event_map-extension ## Requirements * [event_calendar](http://github.com/radiant/radiant-event-calendar-extension) extension * [layouts](http://github.com/squaretalent/radiant-layouts-extension) or [share_layouts](http://github.com/radiant/radiant-share-layouts-extension) extension * [geokit](http://geokit.rubyforge.org/) gem ## Configuration There is one required config setting if you're using the full-page map controller: * `event_map.layout` is the name of the layout used by the controller If you're only using the `events:googlemap` radius tag then this isn't required. ## Basic Usage ### Linking to maps We override the `url` method of EventVenue to return a map link if no other url is defined. The format of those links is determined by the link template stored in the config setting `event_map.link_format`. The markers :lat, :lng and :title will be replaced with the the correct value for each event venue. There are also two shortcuts: * 'google' is the default and equivalent to `http://maps.google.com/maps?q=:lat+:lng+(:title)` and will drop a pin on a google map. * 'bing' is equivalent to `http://www.bing.com/maps/?v=2&cp=:lat~:lng&rtp=~pos.:lat_:lng_:title&lvl=15&sty=s&eo=0`, which will display a 1:25000 ordnance survey map (if you're in the UK) with a destination flag at your chosen point. ### Placing a map on one of your pages For simple uses this radius tag might suffice: For more searchability you need to use the full-page map controller. ### Displaying a map page Create a layout that includes a `map_canvas` div and these page parts: * `map_js` is required. It brings in the javascripts (and can be used in the header or at the end of the page as you prefer) * `title` is the page title and can also be shown with `r:title` * `faceting` gives the option to remove any date filters that have been applied. If you add the `taggable_events` extension it gets more useful. Here's a starting point: <r:title />

Make sure that `Radiant::Config['event_map.layout']` matches exactly the _name_ of this layout. ### custom markers To display a different marker for (events in) each calendar, set `Radiant::Config['event_map.use_calendar_icons?']` to true and then create shadow and marker files at paths like these: * /images/map_icons/slug.png * /images/map_icons/slug_shadow.png where 'slug' is the slug of each calendar. Basic pin and shadow images are included for you to modify and name appropriately. If a venue has several events then the first will event will set the marker. NB. we're not doing anything fancy here with offsets or masks: if you need that kind of detail then a bit more javascript is required. ### javascript compatibility The map javascript is generated by the EventVenuesController using `app/views/event_venues/index.js.erb`. You should find that it automatically populates the map with or without jquery present. ### JSON interface If you don't want to use the included scripts, you can skip that whole mechanism and work with the event data instead. EventVenuesController provides a simple JSON interface. Usually it's at /map and looks for addresses like this: /map everything /map/2010 events in 2010 /map/2010/12/ events in December 2010 /map/2010/12/12 events on 12 December 2010 If you're using `taggable_events` then we also inherit the tag-faceting interface here. ## Bugs and features [Github issues](http://github.com/spanner/radiant-event_map-extension/issues) please, or for little things an email or github message is fine. ## Author & Copyright Copyright 2008-2011 Will at spanner.org.
