# Sequel::SchemaDumper

### Public Instance Methods

column_schema_to_ruby_type(schema) click to toggle source

Convert the column schema information to a hash of column options, one of which must be :type. The other options added should modify that type (e.g. :size). If a database type is not recognized, return it as a String type.

dump_foreign_key_migration(options=OPTS) click to toggle source

Dump foreign key constraints for all tables as a migration. This complements the :foreign_keys=>false option to dump_schema_migration. This only dumps the constraints (not the columns) using alter_table/add_foreign_key with an array of columns.

Note that the migration this produces does not have a down block, so you cannot reverse it.

    # File lib/sequel/extensions/schema_dumper.rb, line 71
    def dump_foreign_key_migration(options=OPTS)
      ts = tables(options)
      Sequel.migration do  change do#{ts.sort_by{|t| t.to_s}.map{|t| dump_table_foreign_keys(t)}.reject{|x| x == ''}.join("\n\n").gsub(/^/o, '    ')}  endend
    end

dump_indexes_migration(options=OPTS) click to toggle source

Dump indexes for all tables as a migration. This complements the :indexes=>false option to dump_schema_migration. Options:

:same_db | Create a dump for the same database type, so don't ignore errors if the index statements fail.
:index_names | If set to false, don't record names of indexes. If set to :namespace, prepend the table name to the index name if the database does not use a global index namespace.

    # File lib/sequel/extensions/schema_dumper.rb, line 89
    def dump_indexes_migration(options=OPTS)
      ts = tables(options)
      Sequel.migration do  change do#{ts.sort_by{|t| t.to_s}.map{|t| dump_table_indexes(t, :add_index, options)}.reject{|x| x == ''}.join("\n\n").gsub(/^/o, '    ')}  endend
    end

dump_schema_migration(options=OPTS) click to toggle source

Return a string that contains a Sequel::Migration subclass that when run would recreate the database structure. Options:

:same_db | Don't attempt to translate database types to ruby types. If this isn't set to true, all database types will be translated to ruby types, but there is no guarantee that the migration generated will yield the same type. Without this set, types that aren't recognized will be translated to a string-like type.
:foreign_keys | If set to false, don't dump foreign_keys (they can be

    added later via #dump_foreign_key_migration)

:indexes | If set to false, don't dump indexes (they can be added later via dump_index_migration).
:index_names | If set to false, don't record names of indexes. If set to :namespace, prepend the table name to the index name.

    # File lib/sequel/extensions/schema_dumper.rb, line 113
    def dump_schema_migration(options=OPTS)
      options = options.dup
      if options[:indexes] == false && !options.has_key?(:foreign_keys)
        # Unless foreign_keys option is specifically set, disable if indexes
        # are disabled, as foreign keys that point to non-primary keys rely
        # on unique indexes being created first
        options[:foreign_keys] = false
      end

      ts = sort_dumped_tables(tables(options), options)
      skipped_fks = if sfk = options[:skipped_foreign_keys]
        # Handle skipped foreign keys by adding them at the end via
        # alter_table/add_foreign_key.  Note that skipped foreign keys
        # probably result in a broken down migration.
        sfka = sfk.sort_by{|table, fks| table.to_s}.map{|table, fks| dump_add_fk_constraints(table, fks.values)}
        sfka.join("\n\n").gsub(/^/, '    ') unless sfka.empty?
      end

      Sequel.migration do  change do#{ts.map{|t| dump_table_schema(t, options)}.join("\n\n").gsub(/^/o, '    ')}#{"\n    \n" if skipped_fks}#{skipped_fks}  endend
    end

dump_table_schema(table, options=OPTS) click to toggle source

Return a string with a create table block that will recreate the given table's schema. Takes the same options as dump_schema_migration.

    # File lib/sequel/extensions/schema_dumper.rb, line 142
    def dump_table_schema(table, options=OPTS)
      table = table.value.to_s if table.is_a?(SQL::Identifier)
      gen = dump_table_generator(table, options)
      commands = [gen.dump_columns, gen.dump_constraints, gen.dump_indexes].reject{|x| x == ''}.join("\n\n")
      "create_table(#{table.inspect}#{', :ignore_index_errors=>true' if !options[:same_db] && options[:indexes] != false && !gen.indexes.empty?}) do\n#{commands.gsub(/^/o, '  ')}\nend"
    end
