Tag Cloud Helper for Sunspot and ActsAsTaggableOn

Fork of sgarza/tag_cloud_helper (http://github.com/sgarza/tag_cloud_helper) providing functionality for contexts or (sub-sets of tags) in the form of Sunspot search facets (Solr)

Dependency

Tag Cloud Helper depends on

• mbleigh/acts-as-taggable-on at http://github.com/mbleigh/acts-as-taggable-on

• outoftime/sunspot_rails at http://github.com/outoftime/sunspot_rails/

To use Tag Cloud Helper

1. Install the plugin by running

    script/plugin install git://github.com/edavey/tag_cloud_helper.git
   

   This will install the plugin in your vendor/plugins directory.

2. Use the following helper method in your view, e.g.:

      <%= tag_cloud @keywords, :model => :article, :context => :keyword, :limit => 25 -%>
   

   where the signature is: tag_cloud(collection_of_facet_rows, {context, model, limit=30})

I assume the following:

• that your model name corresponds to the name of the controller which your links will use. The example generates links like:

    /articles?keyword=jobs
  

• that if you are filtering your search results by other facets then you wish to preserve any existing url parameters and get links like:

    /articles?filter=video&keyword=jobs&query=money
  

• that you don't wish to preserve a page parameter, i.e. if you add the jobs keyword then you want to see the first page of the new results set.
