But Isn't the same thing as saving the object in the
request["session"]["myobject"] ?.
The dictionnary is not being erase entirely, but it is the associate value
that are reset to empty string. I though at first that I might trigger the
__init__ , but when I trace it, the object is not being reinitialyse.
Is it possible that the object is only keep in memory because I use a third
level method to assign the values?
class object1:
def __init__(self):
self.key1 = object2()
class object2:
def do2(self, v):
self.key2 = { "value": v }
In views.py I do :
myobj = object1()
myobj.key1.do2("value")
