Functions ¶
func ToMongoString ¶
func ToMongoString(s customsort.Sort) (bson.D, error)
ToMongoString converts the `Sort` to MongoDB sort format.
Types ¶
type MongoDB ¶
type MongoDB struct {
*storage.Storage
// Client is the MongoDB client.
Client *mongo.Client `json:"-" validate:"required"`
// Config is the MongoDB configuration.
Config *Config `json:"-"`
// Database to connect to.
Database string `json:"database" validate:"required"`
// Target allows to set a static target. If it is empty, the target will be
// dynamic - the one set at the operation (count, create, delete, etc) time.
// Depending on the storage, target is a collection, a table, a bucket, etc.
// For ElasticSearch, for example it doesn't have a concept of a database -
// the target then is the index. Due to different cases of ElasticSearch
// usage, the target can be static or dynamic - defined at the index time,
// for example: log-{YYYY}-{MM}. For Redis, it isn't used at all.
Target string `json:"-" validate:"omitempty,gt=0"`
}
MongoDB storage definition.
func (*MongoDB) Count ¶
func (m *MongoDB) Count(ctx context.Context, target string, prm *count.Count, options ...storage.Func[*count.Count]) (int64, error)
Count returns the number of items in the storage.
func (*MongoDB) Create ¶ added in v0.0.15
func (m *MongoDB) Create(ctx context.Context, id, target string, v any, prm *create.Create, options ...storage.Func[*create.Create]) (string, error)
Create data.
NOTE: Not all storages returns the ID, neither all storages requires `id` to be set.
WARN: MongoDB relies on the model (`v`) `_id` field to be set, otherwise it will generate a new one. IT'S UP TO THE DEVELOPER TO SET THE `_ID` FIELD.
func (*MongoDB) Delete ¶
func (m *MongoDB) Delete(ctx context.Context, id, target string, prm *delete.Delete, options ...storage.Func[*delete.Delete]) error
Delete removes data.
func (*MongoDB) List ¶
func (m *MongoDB) List(ctx context.Context, target string, v any, prm *list.List, opts ...storage.Func[*list.List]) error
List data.
WARN: In general, projections that include non-indexed fields or fields that are part of a covered index (i.e., an index that includes all the projected fields) are less likely to impact performance.
NOTE: It uses param.List.Search to query the data.
