title: using different serializer for the same model appearing at different places
body: <p>hope someone can help me on this</p>
  
  <p>I am using the rails serializers to format my model output to a RESTFul JSON web service.</p>
  
  <p>Now my question is...</p>
  
  <p>Say if I have a model user, that I will be using everywhere amongst the application.  Some of the places I want pretty much all the user data (name, email, phone, addresses...etc.), while others I just want the name, email.  However, these user objects are attachment to some main model via has_many, belongs_to...etc.</p>
  
  <p>So how could I indicate which serializer I want for users at each specific output.</p>
  
  <p>Thanks in advance</p>
