Hi,
I'm trying to use a dtml tree tag with an External Method, but it isn't =
working.
The code that I'm using is:
<dtml-in obj_fs> -> this is the external Method
<dtml-tree branches_expr=3D"objectValues(['Folder','External =
Method'])" assume_children=3D1>
<dtml-var sequence-item>
</dtml-tree>
</dtml-in>
And the code in obj_fs is:
def obj_fs(self):
import os, os.path
lst=3Dos.listdir("/var/spool/news/articles")
return lst
What I'm trying with this, is that the zope programme go get me the =
folders in the directory "/var/spool/news/articles", show those folders =
and with the tree, it will appear a plus sign that when we click on this =
plus sign, it will display the subfolders in the folder that we have =
clicked.
The result must be like the Windows Explorer, with folder and =
subfolders.=20
Is the tree tag compatible with the External Method? If yes, this is not =
working. Can anyone help me to figure where is the error and tell me =
another way to can make this result?
Please send your answers to: psilva@ruido-visual.pt
Thanks,
Pedro
