Can we do $all query in sails/waterline js?

问题

I am using mongodb and sails/waterlinejs

One of my documents has a field "participants": ["1" ,"2" ,"3"]

I would like to make a mongodb query:

Document.find({participants: {$all: ["1", "2"]}})

But I notice that if I do it in waterline, it returns me all the documents that contains EITHER "1" OR "2".

I would like to get BOTH "1" AND "2"

Is this something that I have to do in native query? Does waterline have a doc somewhere that lists all the available operators for .find()?

Thanks

回答1:

Try to use $and, You should do like this.

query = Model.where({"$and": [ { "participants": "1" }, { "participants": "2" } ] });

You could use the modifier in.

Searches for records where the value is in the list of values.

Model.find({
  participants: { in: ['foo', 'bar'] }
})

Edit

Provide an array to find records whose value for this attribute exactly matches any of the specified search terms.

Model.find({
  participants : ['foo', 'bar']
});
