Functions

func DecisionContext

func DecisionContext(parent context.Context, decision error) context.Context

DecisionContext creates a new context from the given parent context with a policy decision attach to it.

func DecisionFromContext

func DecisionFromContext(ctx context.Context) (error, bool)

DecisionFromContext retrieves the policy decision from the context.

func NewPolicies

func NewPolicies(schemas ...interface{ Policy() ent.Policy }) ent.Policy

NewPolicies creates an ent.Policy from list of mixin.Schema and ent.Schema that implement the ent.Policy interface.

Types

type MutationPolicy

type MutationPolicy []MutationRule

MutationPolicy combines multiple mutation rules into a single policy.

func (MutationPolicy) EvalMutation

func (policies MutationPolicy) EvalMutation(ctx context.Context, m ent.Mutation) error

EvalMutation evaluates a mutation against a mutation policy.

type MutationRule

type MutationRule interface {
	EvalMutation(context.Context, ent.Mutation) error
}

MutationRule defines the interface deciding whether a mutation is allowed and optionally modify it.

type Policies

type Policies []ent.Policy

Policies combines multiple policies into a single policy.

func (Policies) EvalMutation

func (policies Policies) EvalMutation(ctx context.Context, m ent.Mutation) error

EvalMutation evaluates the mutation policies. If the Allow error is returned from one of the policies, it stops the evaluation with a nil error.

func (Policies) EvalQuery

func (policies Policies) EvalQuery(ctx context.Context, q ent.Query) error

EvalQuery evaluates the query policies. If the Allow error is returned from one of the policies, it stops the evaluation with a nil error.

type QueryPolicy

type QueryPolicy []QueryRule

QueryPolicy combines multiple query rules into a single policy.

func (QueryPolicy) EvalQuery

func (policies QueryPolicy) EvalQuery(ctx context.Context, q ent.Query) error

EvalQuery evaluates a query against a query policy.

type QueryRule

type QueryRule interface {
	EvalQuery(context.Context, ent.Query) error
}

QueryRule defines the interface deciding whether a query is allowed and optionally modify it.
