Added a :style option for rendering partials with RecordIdentifier

Reported by Justin French | December 27th, 2008 @ 01:21 PM | in 2.x

Added a :style option for rendering partials with RecordIdentifier, allowing the same object to be rendered with a different partial to suit different rendering situations.

The value of :style is used to add a suffix to the standard partial name provided by RecordIdentifier#partial_path. Examples:

# Before:
<%= render :partial => "posts/post_summary", :locals => { :post => @post } %> 
# After:
<%= render :partial => @post, :style => :summary %>

# Before:
<%= render :partial => "posts/post_summary", :collection => @posts, :as => :post %> 
# After:
<%= render :partial => @posts, :style => :summary %> 

This also heavily reduces the noisy view code if you want to use an alternate partial on a collection of objects with differing classes, like records from a table with STI.

    I would almost think that the latest improvement to render would make this unneeded. See

    You'd do your example as: <%= render("post_summary", :post => @post) %>. That seems just as long and doesn't require a special exception for :style.

    For the record, have been discussing this elsewhere. DHH's solution only solves one of the cases (not the collection version), but we're coming up with a plan B. Will leave this in wontfix.
