Re: [Zope] accessing object from a list constructed in init.py

2006-07-23 Thread Alexis Roda


En/na kevin7kal ha escrit:

Ok, thank you for that.
I can create the list of objects from the __of__(self) attribute without 
the wrapper error now,

but I still cannot access that attribute through zope.
Here is my code again, along with my zope content.


Another thing I've missed, class1 isn't persistent, but you store 
instances in Zclass2.attribute1a. This can explain the can't pickle error.

Re: [Zope] accessing object from a list constructed in init.py

2006-07-23 Thread kevin7kal

I've changed my code a bit, adding the docstring, Persistent to all 
classes and
__allow_access_to_unprotected_attributes__ = 1 to all classes.  Still, I 
recieve the same error.


I have changed the code so _attribute1a is a single instance of class1 
instead of a list of  containing multiple instances of class1 and I can 
access the attributes of the object without issue.
Are the objects automatically unwrapped when added to a list?  is there 
a way around this?

I can send the code again if need be.

so here is the code again, this time with only the single object in 
attribute1a.

--myClass.py--
import Acquisition
from persistent import Persistent

class class1(Acquisition.Explicit,Persistent):
   ''' a simple class with some attributes and methods'''
   __allow_access_to_unprotected_attributes__ = 1
   attribute1 = 'attribute 1'
   attribute2 = 'attribute 2'
   _number = ''
   def __init__(self,number2):
   '''simple init for the class'''
   self._number=number2*3
  
   def method1(self):

   '''return a string methd1'''
   mthd1 =  'methd1'
   return mthd1
   def method2(self):
   ''' return a string methd2'''
   mthd2 = 'method2'
   return mthd2
   def _get_number(self):
   return self._number
   number = property(fget=_get_number)

class class2(Acquisition.Explicit,Persistent):

   ''' a second simple class with some attributes and methods'''
   __allow_access_to_unprotected_attributes__ = 1
   _attribute1a = []
   attribute2a = []
   def __init__(self):
   '''create a list of class1 objects in attribute1a'''
   #i=1
   #while i  5:
   #obj = class1(i)
   #self._attribute1a.append(obj)
   #i=i+1
   self._attribute1a = class1(5)
   def method1a(self):
   '''instantiate class1 as object and return object usable by zope'''
   obj = class1(5)
   return obj.__of__(self)
   def method2a(self):
   '''returns class1.method1()'''
   c1m1 = class1.method1()
   return c1m1
   def get_attribute1a(self):
   #if self._attribute1a != []:
   #i = len(self._attribute1a)
   #j = 0
   #while j != i-1:
   #self._attribute1a[j] = self._attribute1a[j].__of__(self)
   #j = j+1
   #else:
   obj = self._attribute1a
   return obj.__of__(self)
   attribute1a = property(fget=get_attribute1a)
   attribute1b = property(fget=method1a)
   attribute2b = property(fget=method2a)

Ok, thank you for that.
I can create the list of objects from the __of__(self) attribute 
without the wrapper error now,

but I still cannot access that attribute through zope.
Here is my code again, along with my zope content.


Another thing I've missed, class1 isn't persistent, but you store 
instances in Zclass2.attribute1a. This can explain the can't pickle 
error.

Sorry, my fault, should be __allow_access_to_unprotected_subobjects__. 
If it does work then add the security declarations.

Re: [Zope] accessing object from a list constructed in init.py

2006-07-23 Thread kevin7kal


That did not work for me either.
It was also suggested that I try inheriting from folder rather than
re-inventing folder.
Still no dice.
I think there is something that I don't understand about acquisition and
context.  Why can an object be placed into context if it is stored as a
simple attribute of another object, but not if it is an element in a
list?  Or what must be done differently when the objects are elements in
a list?

The piece of the picture you are missing is that the magic of
acquisition happens in the 'getattr' hook:  acquisition-aware objects
create the wrapper (via '__of__') for objects fetched from them via
attribute access.

Containers which want to provide the same semantics for 'getitem' access
have to call '__of__' directly themselves.  For objects derived from
OFS.ObjectManager, that responsibility is delegated to the '_getOb'
method.  Standard folders store their items as attributes, and so their
'_getOb' doesn't have to do anything special::

def _getOb(self, id, default=_marker):
if id[:1] != '_' and hasattr(aq_base(self), id):
return getattr(self, id)
if default is _marker:
raise AttributeError, id
return default

A BTreeFolder, however, does not store items as attributes;  its
'_getOb' looks like::

def _getOb(self, id, default=_marker):
Return the named object from the folder.

tree = self._tree
if default is _marker:
ob = tree[id]
return ob.__of__(self)
else:
ob = tree.get(id, _marker)
if ob is _marker:
return default
else:
return ob.__of__(self)

RE: [Zope] Script execute with every request

2006-07-23 Thread Joshua Burvill









Ok, so I could put a dtml-call   into
my standard_html_header, and any redirects do them with a call to Dieters
script (which may not work with future zope versions) to make sure I am keeping
the original request.



Hmm, is there a better solution anyone knows of? 



Basically I just want to do an insert into a database
of some stuff from each request.

Hi,



Id like to log certain parts of each request

I thought of inserting a dtml-call xxx
into the standard_html_header, but when there is a RESPONSE.redirect, it will
not be the original request that gets logged.



Can anyone offer any suggestions?



Thanks, Josh
