from tg.controllers import CUSTOM_CONTENT_TYPE
from tg import (
expose,
flash,
request,
response,
)
@expose(content_type=CUSTOM_CONTENT_TYPE)
@require(not_anonymous())
@validate(license_select_form, error_handler=index)
@validate(hardware_code_form, error_handler=enter_hardware_code)
def download_authorization_file(self, license_id, hardware_code):
rh = response.headers
rh['Content-Type'] = 'application/octet-stream; charset=utf-8'
disposition = 'attachment; filename="Authorize_%s.auz"' % str(
hardware_code)
rh['Content-disposition'] = disposition
rh['Pragma'] = 'public' # for IE
rh['Cache-control'] = 'max-age=0' #for IE
return authorizations
Works without a hitch for us (TG 2.0.1)

No. exposition is dealt with in TG2 itself before delegating execution
to the action - nesting actions won't work because of this.
