If you don't need this page to be update more then once a day or once a
hour what you can do is this :
You make sub-function that you gonna cache
def __sub_func_NAME():
complex query
return var
def display_func():
var = cache.ram('var',
lambda: __sub_func_samples_list(),
time_expire=3600)
from = RESULT OF YOUR FORM GENERATION
return dict(form=form)
That way you can cache the long query, so it will be slow only once in a
wild...
Sorry, I don't have time to analyse in details if what you are doing could
be optimize. I think that if you just want to make it faster you can follow
the path a suggest as long as your code give you the result you expect.
