title: Rails_admin partial not recognizing variables passed through argument
body: <p>I want to be able to do something like this</p>
  
  <pre><code>rails_admin do
    partial "custom_view", variable: my_variable
  end
  </code></pre>
  
  <p>Rails_admin does not complain, but the model variable is not recognizable inside the partial neither</p>
  
  <p>I tried few other syntaxes such as : <code>partial "custom_view", :variable =&gt; my_variable</code> or <code>partial "custom_view", :locales { :variable =&gt; my_variable }</code>but no luck...</p>
  
  <p>Any clues how to achieve this ?</p>
  
  <p>Thanks!</p>
