I'm working with loopback v4 and I need to use the MongoDB $unset
extended operator. Documentation on MongoDB connector indirectly states that it can be used (see here) , but I can't find any example/documentation on how is it supposed to be used on my repository, do you have any hints?
According to the documentation, you need to modify the settings in DataSource
first.
xxx.datasource.ts
export class XxxDataSource extends juggler.DataSource {
static dataSourceName = '...';
constructor() {
super({
"name": "...",
"connector": "mongodb",
"url": "...",
"database": "...",
"allowExtendedOperators": true // <= !!!! default is false
});
}
}
xxx.controller.ts
return await this.xxxRepository.updateById(
"....id....",
{
$unset: {
test: ""
}
} as any // <= !!!! you can using `$unset` now, add `as any` to avoid type error
)
