title: How to document a flask-restplus response with list of strings
body: <p>I am documenting my response models, and need to show the api returns list of string. </p>
  
  <pre><code>["user1","user2"]
  </code></pre>
  
  <p>but the model requires a dictionary(json) format, as follow:</p>
  
  <pre><code>ns.response(200,'Success', NS.model("my_get_model",[{
      "name": fields.String(example="user1"),
  }]))
  </code></pre>
  
  <p>I have tried following codes but none of them work:</p>
  
  <pre><code>ns = Namespace('My Apis')
  
  
  ns.response(200,'Success', [ns.model("my_get_model",
      fields.String(example="user1")
  )])
  </code></pre>
  
  <p>or</p>
  
  <pre><code>ns.response(200,'Success', ["user1"])
  </code></pre>
  
  <p>or</p>
  
  <pre><code>ns.response(200,'Success', ns.model("my_get_model",fields.List(fields.String(example="user1"))))
  </code></pre>
  
  <p>Please advice.</p>
