	// WithGlobalUniqueID sets the universal ids options to the migration.

	// WithDropIndex sets the drop index option to the migration.
	// If this option is enabled, ent migration will drop old indexes
	// that were defined in the schema. This defaults to false.

Functions

func Create 

func Create(ctx context.Context, s *Schema, tables []*schema.Table, opts ...schema.MigrateOption) error

Create creates all table resources using the given schema driver.

func Diff 

func Diff(ctx context.Context, url string, opts ...schema.MigrateOption) error

Diff compares the state read from a database connection or migration directory with the state defined by the Ent schema. Changes will be written to new migration files.

func NamedDiff 

func NamedDiff(ctx context.Context, url, name string, opts ...schema.MigrateOption) error

NamedDiff compares the state read from a database connection or migration directory with the state defined by the Ent schema. Changes will be written to new named migration files.

Types

type Schema 

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

Schema is the API for creating, migrating and dropping a schema.

func NewSchema 

func NewSchema(drv dialect.Driver) *Schema

NewSchema creates a new schema client.

func (*Schema) Create 

func (s *Schema) Create(ctx context.Context, opts ...schema.MigrateOption) error

Create creates all schema resources.

func (*Schema) Diff 

func (s *Schema) Diff(ctx context.Context, opts ...schema.MigrateOption) error

Diff creates a migration file containing the statements to resolve the diff between the Ent schema and the connected database.

func (*Schema) NamedDiff 

func (s *Schema) NamedDiff(ctx context.Context, name string, opts ...schema.MigrateOption) error

NamedDiff creates a named migration file containing the statements to resolve the diff between the Ent schema and the connected database.

func (*Schema) WriteTo 

func (s *Schema) WriteTo(ctx context.Context, w io.Writer, opts ...schema.MigrateOption) error

WriteTo writes the schema changes to w instead of running them against the database. 

if err := client.Schema.WriteTo(context.Background(), os.Stdout); err != nil {
	log.Fatal(err)
}
