I do not understand the question.
Something is creating the object (a function or a constructor, which
is also a function).
myobject=MyObject()
You can only reference the object after it has been created or after
is has been extracted from cache. This means the constructor of the
object must be called the first time but not the second time.
myobject = get_me_the_object_from_cache_or_make_one_using(MyObject())
In web2py this is translated as
myobject = cache.ram('myobject',lambda: MyObject(), 10**10)
If you already have the object you want to cache you can do this:
if I already_have_the object_I_want_to_cache:
cache.ram('myobject',lambda:myobject,0)
else: # get me the object
myobject = cache.ram('myobject',lambda: None,10**10)
Since web2py 1.65.4 you can use None instead of 10**10 and None means:
never expires. 0 means expires now.
