[Zope] Help with tree tag and localfs

[sysman]

I did as you suggested, but I am afraid I am still a newbie at the =
python scripting. =20

What I did was setup two scripts:
filter_tree_nodes
pres_docs_get_url

And replaced 'root' with my localfs folder name (zinesfolder).

I setup pres_docs_get_url with 4 parameters, but I don't know which to =
setup for sure.  Are these correct?

item_id, item_ext_list, item_name, root_url

I still get nothing for objects in the folder.  Just a thought, could =
this have something to do with LocalFS and Zope 2.6.0?=20

In my case:

<dtml-let root=3D"pres_docs_storage">
  <dtml-tree name=3Droot branches_expr=3D"filter_tree_nodes()" nowrap =
single>
    <dtml-var "pres_docs_get_url( getId(),hasChildNodes(),=20
_['tree-item-url'], _['tree-item-expanded'])">
  </dtml-tree>
</dtml-let>

where pres_docs_storage is the LocalFS instance.

filter_tree_nodes:

obs =3D context.objectValues()
for ob in obs:
    if ob.getId() =3D=3D 'index.html':
        obs.remove(ob)  #not a good idea.. I have since modified this =
one

return obs

pres_docs_get_url:

#get URL (item_id, children obtained by hasChildNodes())
import string

item_ext_list =3D item_id.split('.')
item_name =3D item_ext_list[0][2:]
item_name =3D item_name.replace('_',' ')

root_url =3D container.REQUEST.BASE0
html =3D ''

if int(children) !=3D 0:
    if not expanded:
        html =3D '<img=20
src=3D\''+context.images.absolute_url()+'/help_book_closed_icon\'>&nbsp;<=
a=20
href=3D\'http://www.neuro-bs.com/pres_docs/html/'+item_url+'\'=20
target=3D\'content\'=20
class=3D\'help_menu_folder\'>'+string.capwords(item_name)+'</a>'
    else:
        html =3D '<img=20
src=3D\''+context.images.absolute_url()+'/help_book_open_icon\'>&nbsp;<a =

href=3D\'http://www.neuro-bs.com/pres_docs/html/'+item_url+'\'=20
target=3D\'content\'=20
class=3D\'help_menu_folder\'>'+string.capwords(item_name)+'</a>'

else:
    html =3D '<img=20
src=3D\''+context.images.absolute_url()+'/help_page_icon\'>&nbsp;<a=20
href=3D\'http://www.neuro-bs.com/pres_docs/html/'+item_url+'\'=20
target=3D\'content\'=20
class=3D\'help_menu_item\'>'+string.capwords(item_name)+'</a>'
=20
return html
