Table resource

To create a resource with exist table exist in project, pass table with table path:

resource = project.resources.create('table', 'test_table_resource', table: "test_table partition(partname='part1')")

please note the table argument format:

• "tablename partition(col=value,[col=value])" for table with partition
• "tablename" for table without any partitions

Get Resource

To get resource content:

resource = project.resources.get('test_file_resource')

File.open(resource.name, "w") do |f|
  f.write resource.content
end

To get resource information except content:

resource = project.resources.head('test_file_resource')
