Activeadmin sortable by multiple columns

问题

Is there any possibility to sort activeadmin table using multiple columns?

I've found an issue that says it is impossible now. But I wonder if anyone has implemented such functionality?

回答1:

I've faced same issue. Judging by source code this feature isn't supported

    def sort_order(chain)
      params[:order] ||= active_admin_config.sort_order
      if params[:order] && params[:order] =~ /^([\w\_\.]+)_(desc|asc)$/
        column = $1
        order  = $2
        table  = active_admin_config.resource_table_name
        table_column = (column =~ /\./) ? column :
          "#{table}.#{active_admin_config.resource_quoted_column_name(column)}"

        chain.reorder("#{table_column} #{order}")
      else
        chain # just return the chain
      end
    end

But there is monkey patch solution.
