  1. POSpecifying name of rails partial to render using a variable
    text
    copied!<p>Is it possible in Rails 3.0 to render a partial where the name of the partial is stored in a variable?</p> <p>I am attempting something similar to:</p> <pre><code>&lt;%= escape_javascript(raw render :partial =&gt; @partial_name, :locals =&gt; { :value =&gt; @value} )%&gt; </code></pre> <p><strong>Updated with more details</strong></p> <p>In my application I have a set of models using multi-table inheritance, for example lets say I have a base model 'cupcake' and variants such as 'AwesomeCupcake' and 'AlrightCupcake'. </p> <p>Each of these models have their own custom partial for displaying information and follow the naming scheme: '_awesome_cupcake' and '_alright_cupcake'. </p> <p>On a page I have links to each type of cupcake in which I want the controller to accept a parameter and dynamically derive which partial to render. The following works as wanted if (in the new.js.erb file) I replace '@partial_name' with something such as 'awesome_cupcake'.</p> <p>Here is a little more information into how my components are laid out:</p> <p><strong>application.js</strong></p> <pre><code>$('#set_cupcake').click(function () { $.getScript('/cupcakes/new.js?cupcake_type=awesome'); }); </code></pre> <p><strong>cupcakes_controller.rb</strong></p> <pre><code>def new cupcake_type = "#{params[:cupcake_type].capitalize}Cupcake" if Object.const_defined? cupcake_type @cupcake = cupcake_type.constantize.new @partial_name = "#{params[:cupcake_type]}_cupcake" end end </code></pre> <p><strong>views/cupcakes/new.js.erb</strong></p> <pre><code>$('#cupcakes') .append("&lt;%= escape_javascript(raw render :partial =&gt; @partial_name, :locals =&gt; { :cupcake =&gt; @cupcake } ) %&gt;") </code></pre>
