body: <p>Is it possible to do a find then save using async/await promise?</p>
  
  <p>I have the following code:</p>
  
  <pre><code>try {
      var accounts = await Account.find()
      .where("username").in(["email@gmail.com"])
      .exec();
      accounts.password = 'asdf';
      accounts.save();
  } catch (error) {
      handleError(res, error.message);
  }
  </code></pre>
  
  <p>and I am getting the following error:</p>
  
  <pre><code>ERROR: accounts.save is not a function
  </code></pre>
