I'm still not entirely sure what you are after. Assuming that you have a form
that you
- want to display
- validate
- perform some background task through threading or subprocesses
- while the form is displayed again
then the actions and form should (roughly) laid out as this:
class MyForm(TableForm): # or list or whatever
.... # fields etc.
my_form = MyForm("my_form",
action = "/perform_action" # use actual path to MyController.perform_action
)
class MyController(...):
@expose("template")
def display_form(self):
tmpl_context.my_form = my_form
return {}
@expose()
@validate(my_form, error_handler=display_form)
def perform_action(self, param_1, param_2, ..):
do_something_in_background(param_1, param_2, ...)
flash("I'm busy fulfilling your request, master!")
redirect("/display_form")
