Types

type BillProductFunc

type BillProductFunc func(context.Context, *ent.BillProductMutation) (ent.Value, error)

The BillProductFunc type is an adapter to allow the use of ordinary function as BillProduct mutator.

func (BillProductFunc) Mutate

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

Mutate calls f(ctx, m).

type CategoryFunc

type CategoryFunc func(context.Context, *ent.CategoryMutation) (ent.Value, error)

The CategoryFunc type is an adapter to allow the use of ordinary function as Category mutator.

func (CategoryFunc) Mutate

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

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 Condition

type Condition func(context.Context, ent.Mutation) bool

Condition is a hook condition function.

func And

func And(first, second Condition, rest ...Condition) Condition

And groups conditions with the AND operator.

func HasAddedFields

func HasAddedFields(field string, fields ...string) Condition

HasAddedFields is a condition validating `.AddedField` on fields.

func HasClearedFields

func HasClearedFields(field string, fields ...string) Condition

HasClearedFields is a condition validating `.FieldCleared` on fields.

func HasFields

func HasFields(field string, fields ...string) Condition

HasFields is a condition validating `.Field` on fields.

func HasOp

func HasOp(op ent.Op) Condition

HasOp is a condition testing mutation operation.

func Not

func Not(cond Condition) Condition

Not negates a given condition.

func Or

func Or(first, second Condition, rest ...Condition) Condition

Or groups conditions with the OR operator.
