Functions

func FixedError

func FixedError(err error) ent.Hook

FixedError is a hook returning a fixed error.

func If

func If(hk ent.Hook, cond Condition) ent.Hook

If executes the given hook under condition.

hook.If(ComputeAverage, And(HasFields(...), HasAddedFields(...)))

func On

func On(hk ent.Hook, op ent.Op) ent.Hook

On executes the given hook only for the given operation.

hook.On(Log, ent.Delete|ent.Create)

func Reject

func Reject(op ent.Op) ent.Hook

Reject returns a hook that rejects all operations that match op.

func (T) Hooks() []ent.Hook {
	return []ent.Hook{
		Reject(ent.Delete|ent.Update),
	}
}

func Unless

func Unless(hk ent.Hook, op ent.Op) ent.Hook

Types

type CardFunc

type CardFunc func(context.Context, *ent.CardMutation) (ent.Value, error)

The CardFunc type is an adapter to allow the use of ordinary function as Card mutator.

func (CardFunc) Mutate

func (f CardFunc) Mutate(ctx context.Context, m ent.Mutation) (ent.Value, error)

Mutate calls f(ctx, m).

type Chain

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

Chain acts as a list of hooks and is effectively immutable. Once created, it will always hold the same set of hooks in the same order.

func NewChain

func NewChain(hooks ...ent.Hook) Chain

NewChain creates a new chain of hooks.

func (Chain) Append

func (c Chain) Append(hooks ...ent.Hook) Chain

Append extends a chain, adding the specified hook as the last ones in the mutation flow.

func (Chain) Extend

func (c Chain) Extend(chain Chain) Chain

Extend extends a chain, adding the specified chain as the last ones in the mutation flow.

func (Chain) Hook

func (c Chain) Hook() ent.Hook

Hook chains the list of hooks and returns the final hook.

type CommentFunc

type CommentFunc func(context.Context, *ent.CommentMutation) (ent.Value, error)
