[Visualpython-users] Pickling Visual python objects.

[Chris L. <chr...@sp...>]

I'm trying to find a flexible way of storing visual objects in a 
database. I had considered building a set of schema's to describe the 
objects but a desire to store other parameters along with the visual 
objects made me feel that might not be as maintainable as I might like 
so I thought of pickling visual objects and saving the serialized output.
Upon trying this I get:

Traceback (most recent call last):
   File "<pyshell#36>", line 1, in <module>
     pickle.dump(data, output)
   File "C:\Python25\lib\pickle.py", line 1362, in dump
     Pickler(file, protocol).dump(obj)
   File "C:\Python25\lib\pickle.py", line 224, in dump
     self.save(obj)
   File "C:\Python25\lib\pickle.py", line 286, in save
     f(self, obj) # Call unbound method with explicit self
   File "C:\Python25\lib\pickle.py", line 562, in save_tuple
     save(element)

     self.save_global(obj)
   File "C:\Python25\lib\pickle.py", line 748, in save_global
     (obj, module, name))

Is this a non starter or might it be worthwhile to strip out the 
parameters of a visual object and repopulate the object upon pickle.load()?
