Method: Sequel::Schema::CreateTableGenerator#dump_indexes

Defined in:
lib/sequel/extensions/schema_dumper.rb

#dump_indexes(options = OPTS) ⇒ Object

Dump this generator’s indexes to a string that could be evaled inside another instance to represent the same indexes. Options:

:add_index

Use add_index instead of index, so the methods can be called outside of a generator but inside a migration. The value of this option should be the table name to use.

:drop_index

Same as add_index, but create drop_index statements.

:ignore_errors

Add the ignore_errors option to the outputted indexes
