Nesta::Plugin::RelatedByCategory

A plugin for finding related articles to a Nesta article, based on a dead-simple idea:

Given pages A and B, the more categories A and B have in common, the higher B's relevance to A.

Add this line to your application's Gemfile:

gem 'nesta-plugin-related-by-category'

And then execute:

$ bundle

Or install it yourself as:

$ gem install nesta-plugin-related-by-category

In your Nesta /views folder, declare a related_articles.haml with something like the following:

- if has_related_articles?(@page)
  %section.related-articles
    %h2 Related articles
    %ul
      - related_by_category(@page).each do |article|
        %li
          %a(href="#{article.abspath}")= article.heading

Then, at the bottom of your template file (page.haml is default), reference it:

= haml :related_articles, :layout => false

By default, the plugin will display 3 articles; this can be overridden by a number of your choice:

related_by_category(@page, 5) # 2nd argument is the number of articles to display.
