func (*Model) Average ¶

func (self *Model) Average(field string, flt interface{}) (float64, error)

func (*Model) Count ¶

func (self *Model) Count(flt interface{}) (uint64, error)

func (*Model) Create ¶

func (self *Model) Create(from interface{}) error

Creates and saves a new instance of the model from the given struct or dal.Record.

func (*Model) CreateOrUpdate ¶

func (self *Model) CreateOrUpdate(id interface{}, from interface{}) error

Creates or updates an instance of the model depending on whether it exists or not.

func (*Model) Delete ¶

func (self *Model) Delete(ids ...interface{}) error

Delete instances of the model identified by the given IDs

func (*Model) Drop ¶

func (self *Model) Drop() error

func (*Model) Each ¶

func (self *Model) Each(destZeroValue interface{}, resultFn ResultFunc) error

func (*Model) Exists ¶

func (self *Model) Exists(id interface{}) bool

Tests whether a record exists for the given ID.

func (*Model) Find ¶

func (self *Model) Find(flt interface{}, into interface{}) error

Perform a query for instances of the model that match the given filter.Filter. Results will be returned in the slice or array pointed to by the into parameter, or if into points to a dal.RecordSet, the RecordSet resulting from the query will be returned as-is.

func (*Model) FindFunc ¶

func (self *Model) FindFunc(flt interface{}, destZeroValue interface{}, resultFn ResultFunc) error

Perform a query for instances of the model that match the given filter.Filter. The given callback function will be called once per result.

func (*Model) Get ¶

func (self *Model) Get(id interface{}, into interface{}) error

Retrieves an instance of the model identified by the given ID and populates the value pointed to by the into parameter. Structs and dal.Record instances can be populated.

func (*Model) GetBackend ¶

func (self *Model) GetBackend() backends.Backend

func (*Model) GetCollection ¶

func (self *Model) GetCollection() *dal.Collection

func (*Model) GroupBy ¶

func (self *Model) GroupBy(fields []string, aggregates []filter.Aggregate, flt interface{}) (*dal.RecordSet, error)

func (*Model) List ¶

func (self *Model) List(fields []string) (map[string][]interface{}, error)

func (*Model) ListWithFilter ¶

func (self *Model) ListWithFilter(fields []string, flt interface{}) (map[string][]interface{}, error)

func (*Model) Maximum ¶

func (self *Model) NewInstance(inits ...dal.InitializerFunc) interface{}

func (*Model) Sum ¶

func (self *Model) Sum(field string, flt interface{}) (float64, error)

func (*Model) Update ¶

func (self *Model) Update(from interface{}) error

Updates and saves an existing instance of the model from the given struct or dal.Record.
