func Batch ¶

func Batch[T any](size int, createFn func(m ...T) (*T, error), override ...T) ([]*T, error)

Batch is a function that repeatedly executes a data creation function ('createFn') a specified number of times and returns a slice of pointers to the created objects.

T is the type of the struct being created (e.g., ds.User). fn is the function that creates a single instance of T (e.g., CreateUser). override allows passing custom field values to override defaults in the created instances.

func Five ¶

func Five[T any](fn func(m ...T) (*T, error), override ...T) ([]*T, error)

Five is a convenience function to create exactly five instances of a data structure T. It is a wrapper around Batch with size=5.

func LookupIUnique ¶

func LookupIUnique[T any](ctx context.Context, db *app.DB, table, column string, value T,
	transformFn func(T) T) (T, error)

LookupIUnique tries to find a unique value in the given table.column by repeatedly querying the database with a transformed version of the input value.

The transformFn is expected to produce a new candidate value (for example, by appending a suffix or incrementing a counter) and must eventually lead to a value that does not exist in the database, otherwise the function will recurse indefinitely (angry emoji).

func NewBookAuthor ¶

func NewBookAuthor() ds.BookAuthor

NewBookAuthor creates a new BookAuthor model populated with fake data.

func NewBookAuthors ¶

func NewBookAuthors(countOpt ...int) []ds.BookAuthor

NewBookAuthors generates and returns a slice of BookAuthor values.

func Ten ¶

func Ten[T any](fn func(m ...T) (*T, error), override ...T) ([]*T, error)

Ten is a convenience function to create exactly ten instances of a data structure T. It is a wrapper around Batch with size=10.

func Two ¶

func Two[T any](fn func(m ...T) (*T, error), override ...T) ([]*T, error)

Two is a convenience function to create exactly two instances of a data structure T. It is a wrapper around Batch with size=2.
