I am trying to combine some filters with no success. I am using the mongodb driver for go
// FindOneByID returns an error on fail, otherwise, it sets the {out} by the result.
func FindOneByID(collectionName string, id *primitive.ObjectID, out interface{}, considerArchivedItems bool) error {
ctx, _ := context.WithTimeout(context.Background(), 2*time.Second)
var filter bson.M
if considerArchivedItems {
filter = bson.M{"_id": id}
} else {
filter = bson.M{"$and": bson.A{ bson.M{"_id": id}, bson.M{isArchived: bson.M{"$ne": false}}}}
}
return database.Collection(collectionName).FindOne(ctx, filter).Decode(out)
}
Now, I insert an object as archived and trying to get the document. The document is inserted as archived, so I want to consider archived items.
However, when I pass in the else, document can be either archived or not (false or true), I still get it anyway. So it means that my $and doesn’t work..
const (
databaseNameUnitTests = "database_name_unit_tests"
databaseCollectionNameUnitTests = "database_name_unit_tests"
)
type Test struct {
ID *primitive.ObjectID `protobuf:"bytes,1,opt,name=id,proto3" json:"_id,omitempty" bson:"_id,omitempty"`
IsArchived bool `protobuf:"varint,2,opt,name=IsArchived,proto3" json:"is_archived,omitempty" bson:"is_archived,omitempty"`
Description string `protobuf:"varint,3,opt,name=Description,proto3" json:"description,omitempty" bson:"description,omitempty"`
}
// func
var item Test
err := mongodb.FindOneByID(databaseCollectionNameUnitTests, insertedID, &item, false)
The following query from Robo 3T : db.getCollection('database_name_unit_tests').find({$and:[{"_id":ObjectId("5d2e8afeb0e106fbe0d5af21")},{"is_archived": {$ne:false}}]})
this works tho, where am I wrong?
