title: Loopback: How to change the name of a model?
body: <p>I have a model with name "aaa_bbb", I want to change the name to aaa-bbb, I would like to know how I can achieve that? Or can I just change the name directly in my model json file? Here is the my current model.json file.</p>
  
  <pre><code>{
    "name": "aaa_bbb",
    "base": "PersistedModel",
    "idInjection": true,
    "options": {
      "validateUpsert": true
    },
    "properties": {
      ...
    },
    "acls": [],
    "methods": []
  }
  </code></pre>
