		Delete(id int64) error
		GetAll(title string, genres []string, filters Filters) ([]*Movie, Metadata, error)
	}
}

func NewModels

func NewModels(db *sql.DB) Models

Return a Models struct containing the initialized MovieModel.

type Movie

type Movie struct {
	ID        int64     `json:"id"`
	CreatedAt time.Time `json:"-"`
	Title     string    `json:"title"`
	Year      int32     `json:"year,omitempty"`
	// if the Runtime field has the underlying value 0 then
	// the omitempty make it considered to be empty and the MarshalJSON
	// won't even be called at all.
	Runtime Runtime  `json:"runtime,omitempty"`
	Genres  []string `json:"genres,omitempty"`
	Version int32    `json:"version"`
}

type MovieModel

type MovieModel struct {
	DB *sql.DB
}

func (MovieModel) Delete

func (m MovieModel) Delete(id int64) error

func (MovieModel) Get

func (m MovieModel) Get(id int64) (*Movie, error)

func (MovieModel) GetAll

func (m MovieModel) GetAll(title string, genres []string, filters Filters) ([]*Movie, Metadata, error)

func (MovieModel) Insert

func (m MovieModel) Insert(movie *Movie) error

func (MovieModel) Update

func (m MovieModel) Update(movie *Movie) error

type Runtime

type Runtime int32

Declare a custom runtime type with underlying type of int32.

func (Runtime) MarshalJSON

func (r Runtime) MarshalJSON() ([]byte, error)

Implement a MarshalJSON() method on the Runtime type so it satisfies the json.Marshaler interface. This should return the JSON-encoded value for the movie runtime it returns "<runtime> mins"

func (*Runtime) UnmarshalJSON

func (r *Runtime) UnmarshalJSON(jsonValue []byte) error

This will change the Runtime and so we make it pointer receiver
