Types

type Adapter 

type Adapter interface {
	SyncSchema(options SchemaSyncOptions, models ...interface{}) error
	Close() error
	Select(collectionName string, args interface{}) (interface{}, error)
	SelectInto(collectionName string, args interface{}, model interface{}) error
	SelectAdvanced(collectionName string, model interface{}, query *SelectQuery) error
	MutationAdapter
	DataFromDatabaseUsingResolveParams(objArr interface{}, modelType reflect.Type, p graphql.ResolveParams) error
	RunInTransaction(InnerTransactionFunc) error
}

Use this interface to implement a database interface This will be used by the abstraction layer

type Collection added in v0.4.0 

type Collection struct {
	Name string
	// contains filtered or unexported fields
}

func (*Collection) Delete added in v0.5.1 

func (c *Collection) Delete(obj interface{}) error

func (*Collection) Insert added in v0.5.1 

func (c *Collection) Insert(obj interface{}) error

func (*Collection) RunInTransaction added in v0.5.1 

func (c *Collection) RunInTransaction(fn TransactionFunc) error

func (*Collection) Select added in v0.4.0 

func (c *Collection) Select(arguments interface{}) (interface{}, error)

func (*Collection) SelectAdvanced added in v0.5.1 

func (c *Collection) SelectAdvanced(model interface{}, query *SelectQuery) error

func (*Collection) SelectInto added in v0.5.1 

func (c *Collection) SelectInto(arguments interface{}, model interface{}) error

func (*Collection) Update added in v0.5.1 

func (c *Collection) Update(obj interface{}) error

type Database added in v0.3.1 

type Database struct {
	// contains filtered or unexported fields
}

func Get added in v0.3.1 

func Get(adapter Adapter, schemaSyncOptions SchemaSyncOptions, models ...interface{}) *Database

func (*Database) Close added in v0.3.1 

func (db *Database) Close() error

func (*Database) Collection added in v0.4.0 

func (db *Database) Collection(model interface{}) *Collection

func (*Database) CustomCollection added in v0.5.1 

func (db *Database) CustomCollection(name string) *Collection

func (*Database) DataFromDatabaseUsingResolveParams added in v0.3.1 

func (db *Database) DataFromDatabaseUsingResolveParams(
	objArr interface{}, modelType reflect.Type, p graphql.ResolveParams) error

func (db *Database) Prepare() error

type InnerTransactionFunc added in v0.4.2 

type InnerTransactionFunc func(MutationAdapter) error

type MutationAdapter added in v0.4.2 

type MutationAdapter interface {
	Insert(collectionName string, obj interface{}) error

}

type MutationAdapterOverlay added in v0.4.2 

type MutationAdapterOverlay struct {
	// contains filtered or unexported fields
}

MutationAdapterOverlay overlays the methods of the mutation adapter on top of the Adapter ones. This is mainly used to provide the abstracted RunInTransaction functionality while keeping the database API the same

	Associations  Collection
	AssociateFrom reflect.StructField
	AssociateTo   reflect.StructField
	Type          relationtype.RelationType
}

type SchemaSyncOptions 

type SchemaSyncOptions struct {
	// Whether to remove columns from the database
	// that can't be found in models.
	//
	// *This is a potentially destructive option, only
	// enable if you're absolutely sure you want to remove
	// old columns*
	//
	// Note that this may not have an effect on document
	// or graph databases.
	RemoveOrphanedColumns bool
}
