Re: [Zope-dev] Recursive folders from Python
Try something like (taken from my own code, so it works for me, caveta
emptor):
def mkcontext(self,context=None):
global default_dd
if not context:
return 'EH!'
c=string.split(context,'/')
newself=self
for a in c:
try:
newself.manage_addFolder(a,createPublic=0,createUserF=0,REQUEST=getattr(self
,'REQUEST',None))
except:
pass
newself=getattr(newself,a) ## this is the relevant line
newself.manage_addLocalRoles(c[-1],['Manager'])
try:
newself.manage_addDTMLMethod('index_html','Start
Page',file=default_dd)
except:
pass
This func takes a slash separated list of folders (actually a NDS context
like 'dacs/media/stf/wmlph' and creates the folder hierarchy.
It's probably overkill for what you want but the relevant line is the
getattr one (as marked).

Re: [Zope-dev] Recursive folders from Python
Try using getattr to get the object... heres a python script to do it a little more cleanly: import string def create_folders(self): path = '/a/b/c' # create a folder for each part of the string, nested. for p in string.split(path, '/'): if p != '': self = create_folder(self, p) return 'Done' def create_folder(folder, id): try: folder.manage_addFolder(id) except: pass new_folder = getattr(folder, id) return new_folder - Original Message - From: "Jason Spisak" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, October 16, 2000 10:46 AM Subject: [Zope-dev] Recursive folders from Python > Zopists, > > Yesterday I was trying to create recursive folders from DTML. > I'd like to do the same from Python. > Does anyonw know why this code won't create a folder within a folder. > It's tells me the id is already in use, so that means it's not > descending into the newly created folder to make another folder. > > def create(self): > for digit in range(0, 10): > folder= self.manage_addFolder(str(digit), str(digit)) > subfolder = self.folder.manage_addFolder(str(digit), str(digit)) > > All my best, > > Jason Spisak > [EMAIL PROTECTED] > > ___ > Zope-Dev maillist - [EMAIL PROTECTED] > http://lists.zope.org/mailman/listinfo/zope-dev > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope ) > ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] Recursive folders from Python
Zopists, Yesterday I was trying to create recursive folders from DTML. I'd like to do the same from Python. Does anyonw know why this code won't create a folder within a folder. It's tells me the id is already in use, so that means it's not descending into the newly created folder to make another folder. def create(self): for digit in range(0, 10): folder= self.manage_addFolder(str(digit), str(digit)) subfolder = self.folder.manage_addFolder(str(digit), str(digit)) All my best, Jason Spisak [EMAIL PROTECTED] ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
