func (*NewRepository) DeleteProduct

func (r *NewRepository) DeleteProduct(ctx context.Context, id int) (err error)

DeleteProduct deletes a product from the database by the given ID. It returns an error if the deletion fails.

func (*NewRepository) GetCategoryByID

func (r *NewRepository) GetCategoryByID(ctx context.Context, id int) (*model.Category, error)

GetCategoryByID retrieves a category by its ID from the database. It returns the category or an error if not found.

func (*NewRepository) GetProductDetail

func (r *NewRepository) GetProductDetail(ctx context.Context, id int) (product *model.Product, err error)

func (*NewRepository) UpdateCategory

func (r *NewRepository) UpdateCategory(ctx context.Context, id int, category *model.Category) error

UpdateCategory updates an existing category in the database. It returns an error if the update fails.

func (*NewRepository) UpdateProduct
