.then()
Execute a Waterline query instance using promises.
.then(callback)
As of Sails v1 and Node.js v8, you can take advantage of
awaitinstead of using this method.
Usage
| Argument | Type | Details | |
|---|---|---|---|
| 1 | callback | A function that runs if the query successfully completes Takes the result of the query as its argument. |
Callback
| Argument | Type | Details | |
|---|---|---|---|
| 1 | result | 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:
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
awaitinstead 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.- For more information, see the bluebird
.then()api docs.
