Mongoose 查询忽略不在模式中的字段

Question

这是我的架构:

const Post = mongoose.model('Post', {
  title: String,
  authorId: String,
})

我想查询它:

Post.find({ authorId: '123', someField: 1 })

结果是 []，我怎样才能让 mongoose 忽略不在模式中的查询字段？

它有一个标志 strictQuery ( https://mongoosejs.com/docs/guide.html#strictQuery )

For backwards compatibility, the strict option does not apply to the filter parameter for queries. Mongoose has a separate strictQuery option to toggle strict mode for the filter parameter to queries.

const mySchema = new Schema({ field: Number }, {
  strict: true,
  strictQuery: true // Turn on strict mode for query filters
});

const MyModel = mongoose.model('Test', mySchema);

// Mongoose will strip out `notInSchema: 1` because `strictQuery` is `true`
MyModel.find({ notInSchema: 1 });
