`.then()`

Execute a Waterline query instance using promises.

usage

.then(callback)

As of Sails v1 and Node.js v8, you can take advantage of await instead of using this method.

Usage

	Argument	Type	Details
1	callback	((function))	A function that runs if the query successfully completes

Takes the result of the query as its argument.

Callback

	Argument	Type	Details
1	result	((Ref?))	The result from the database, if any. Exact data type depends on the query.

Example

To look up the user with the specified email address:

javascript

User.findOne({
  email: req.param('email')
})
.then(function (user){
  if (!user) { return res.notFound(); }
  return res.json(user);
})
.catch(function (err) { return res.serverError(err); });

Notes

Whenever possible, it is recommended that you use await instead of calling this method.

This is an alternative to .exec(). When combined with .catch(), it provides the same functionality.

The .then() function returns a promise to allow for chaining.
