.update()

Update all records matching criteria.

await Something.update(criteria, valuesToSet);

Or:

var updatedRecord = await Something.update(criteria, valuesToSet).fetch();

Usage

	Argument	Type	Details
1	criteria		The Waterline criteria to use for matching records in the database. `update` queries do not support pagination using `skip` and `limit` or projections using `select`.
2	valuesToSet		A dictionary (plain JavaScript object) of values to that all matching records should be updated to have. (Note that, if this model is in "schemaful" mode, then any extraneous keys will be silently omitted.)

Result

Type	Description
	By default, for better performance, the updated records are not provided as a result. But if you chain `.fetch()`, then the array of updated record(s) will be sent back. (Be aware that this requires extra database queries in some adapters.)

Errors

Name	Type	When?
UsageError		Thrown if something invalid was passed in.
AdapterError		Thrown if something went wrong in the database adapter. See Concepts > Models and ORM > Errors for an example of how to negotiate a uniqueness error (i.e. from attempting to create a record with a duplicate that would violate a uniqueness constraint).
Error		Thrown if anything else unexpected happens.

See Concepts > Models and ORM > Errors for examples of negotiating errors in Sails and Waterline.

Meta keys

Key	Type	Details
fetch		If set to `true`, then the array of updated records will be sent back. Defaults to `false`.

For more information on meta keys, see .meta().

Example

await User.update({name:'Pen'})
.set({name:'Finn'});

sails.log('Updated all users named Pen so that their new name is "Finn".  I hope they like it.');
return res.ok();

Fetching updated records

To fetch updated records, use enable the fetch meta key:

var updatedUsers = await User.update({name:'Finn'})
.set({name:'Jake'})
.fetch();

sails.log(`Updated all ${updatedUsers.length} user${updatedUsers.length===1?'':'s'} named "Finn" to have the name "Jake".  Here they are now:`);
sails.log(updatedUsers);

return res.ok();

Notes

This method can be used with await, promise chaining, or traditional Node callbacks.

This method can be used to replace an entire collection association (for example, to replace a user’s list of friends), achieving the same result as the replaceCollection method. To modify items in a collection individually, use the addToCollection or removeFromCollection methods.

Is something missing?
