query.needNesting() function

Whether a fields map asks for any of the model's relations.

Signature:

export function needNesting(model: typeof Model, fields: any): boolean;

Parameters

Parameter	Type	Description
model	typeof Model	Model whose associations to check against.
fields	any	Requested fields map.

Returns:

boolean

true when at least one key names an association.

The cheap test for "does this query need joins at all", used to avoid building an include when the caller only wants columns.
