How to implement?

Initial solution to display the star rating is based on a How To:

  • in the Review node, create field_review_rating of type Integer and add the star options
  • the custom HTML markup for this field is provided by theme_preprocess_field() in template.php
  • create/add field--field-review-rating.tpl.php to the theme's template folder and use the custom HTML markup to override its display
  • Font Awesome Icon Library is loaded in html.tpl.php
  • add the CSS to color the stars in the theme's CSS folder

This works fine when a node is displayed. But what about a list of reviews produced by Views?

How can I reproduce the node's custom display in a Views' display? It's definitely possible but it quickly gets more complicated. It also means that our system will have 2 templates to handle these 2 separate contexts, duplication is rarely ideal and often leads to more work and errors...

AH! a better solution would be to use a content view mode e.g. Teaser instead of fields, that way there is no need to work with Views' templates + the work done in field--field-review-rating.tpl.php 100% recyclable :)
