wrong number of arguments (2 for 1)

[greyblake]

I can't migrate database.
Using version 0.0.2.

Backtrace:

lib/active_record/connection_adapters/mysql2_adapter.rb:381:in `tables'
lib/active_record/connection_adapters/mysql2_adapter.rb:400:in `table_exists?

From source code:

      def tables(name = nil)
        tables = []
        execute("SHOW TABLES", name).each do |field|
          tables << field.first
        end
        tables
      end

      def table_exists?(name)
        return true if super

        name = name.to_s
        schema, table = name.split('.', 2)

        unless table # A table was provided without a schema
          table = schema
          schema = nil
        end

        tables(nil, schema).include? table
      end

As you see #table_exists? calls #tables with 2 parameters.

Thanks for the hint.

I ported the changes from the mysql2-gem (which should solve this) into this extract.

Version 0.0.3 (which has the upstream fixes) is pushed to rubygems and should be good for you.
