 Hello, the things we want to do is to find every media file (DTML 
 document) in a folder structure and change their format. They are a
 few folders deep and the number of folders that contain the file is
 unknown, so I tried to use a recursive way to get access to every
 document.
 
 So this is what I did, I wrote a script named changeType with
 parameter object, which is initially 0. Then when object is 0, just
 set object = context. If in object we found that there's another
 folder called f, just called changeType(f). The script is shown as
 below:
 
 #parameter object = 0 from Products.PythonScripts.standard import
 html_quote request = context.REQUEST RESPONSE =  request.RESPONSE
 
 if object == 0: object = context
 
 folders = object.objectValues(['Folder']) for f in folders: fds =
 f.objectValues(['Folder']) if(len(fds) != 0): f.changeType(f) 
 ...(methods to change format)
 
 But this causes an error:
 
 Error Type: AttributeError Error Value: ‘str’ object has no attribute
 ‘objectValues'


You likely want to use 'ZopeFind', which handles all the recursion for
you.  E.g.:

for _, dtml_doc in context.ZopeFind(obj_metatypes=['DTML Document']):
# do something with 'dtml_doc' here.

[Zope] Zope 2: traversing and modifying DTM doc in folders?

[Dan Gaibel]

Greetings, I have a developer here trying to fix a problem with some legacy 
Zope 2 (2.8.6) material. Basically, she is trying to change properties on a 
DTML document, but so far cannot get the script to recursively search through 
folders to act on every document in the hierarchy.

Any advice is greatly appreciated!

Hello, the things we want to do is to find every media file (DTML document) in 
a folder structure and change their format. They are a few folders deep and the 
number of folders that contain the file is unknown, so I tried to use a 
recursive way to get access to every document.

So this is what I did, I wrote a script named changeType with parameter 
object, which is initially 0. Then when object is 0, just set object = 
context. If in object we found that there's another folder called f, just 
called changeType(f). The script is shown as below:

#parameter object = 0
from Products.PythonScripts.standard import html_quote
request = context.REQUEST
RESPONSE =  request.RESPONSE

if object == 0:
   object = context

folders = object.objectValues(['Folder'])
for f in folders:
   fds = f.objectValues(['Folder'])
   if(len(fds) != 0):
  f.changeType(f)
   ...(methods to change format)

But this causes an error:

Error Type: AttributeError
Error Value: ‘str’ object has no attribute ‘objectValues'
​
I think the reason should be, it doesn't seen object or context as object 
and context but seen them just as strings. But I have no idea about how could I 
solve this or if there's any other way I can call a recursive method to get 
every DTML document in their respective subfolders. Please let me know if you 
have any suggestion/examples on Zope/found another error in my code/etc.
