Zope URL/Page Retrieval with Python
by Samir Mishra 15 Nov '03

15 Nov '03

Hello All, I guess this is more of a Python question. I'm trying to access a page being generated by Zope using Python's urllib2 module. The page requires a username/password be entered before it can be accessed/rendered. I'm stuck on how I can provide user credentials to a website requiring authentication through a Python script. Could someone help me out? Thanks. Regards, Samir

hiding content -metadata/subject filter
by Michael Havard 14 Nov '03

14 Nov '03

I'm trying to set up a system where content authors can upload/edit files on ZOPE in a CMF site and use the default index_html to show a list of files. That works fine. But we need to refine it to allow the authors to hide some content from the index but still have it linkable from a document in the index. Clear as mud right. For example I might have a document that links to several other documents and has images, js, and css attached. I want the user to see the main document but to only access the images and scripts through that document and not see those items in the index. What's the best way? I attempted to use something I saw from zopelabs using a filter on 'Subject':'Indexable' but that failed with an error every time with exceptions.TypeError on 'in ' requires character as left operand in "", at line 9, column 2. _________________________________________________________________ >From Beethoven to the Rolling Stones, your favorite music is always playing on MSN Radio Plus.

get_transaction().commit() does not commit
by Harm_Kirchhoff＠mail.digital.co.jp 14 Nov '03

14 Nov '03

I guess it is another newbie question, but I can not save data to the DB: I open the DB like this: self.st = FileStorage.FileStorage(self.mountedDB) self.db = DB(self.st) self.connection = self.db.open() self.dbroot = self.connection.root() self.dbroot = OOBTree() return (True,'db mounted:'+ self.mountedDB) Next I make a number of changes to self.dbroot: self.dbroot[CstNo] [FY] ['1'] ['E'] = {} self.dbroot[CstNo] [FY] ['1'] ['S'] = {} self.dbroot[CstNo] [FY] ['1'] ['accno'] = {} self.dbroot[CstNo] [FY] ['1'] ['acba' ] = {} self._p_changed = 1 get_transaction().commit() And then I close: get_transaction().commit() # commit any changes that may be pending. self.connection.close() self.db.close() self.st.close() When I open again and try verify whether the keys exist, using self.dbroot.has_key(CstNo) # for example they do not exist. Looking at the DB with a text editor to see what is in there, reveals that there is nothing. The entire program runs through without any error.

Temporary partition problem
by Heimo Laukkanen 14 Nov '03

14 Nov '03

In a machine that is not in my full control is a problem with running zopes that have mosterious databases getting close to 2 gigs. Now there are problems with temp files that Zope puts on /tmp partition that is only 200 megs. I've set in start script TMPDIR to be on /spool in start script with TMPDIR ='/spool/something' EXPORT TMPDIR, but Zope does not follow that. While doing a large copy operation /tmp gets filled AND operation fails, but space on /tmp will not be freed. Python 2.1.3 and Zope 2.6.0 I searched mailinglists and in the past someone has had similar problem, but solution was not said. Any help would be appreciated. -- -huima

PIL: convert an image-object back to file object
by Christoph Landwehr 14 Nov '03

14 Nov '03

Hi, I use an external method utilizing PIL (python image library) to do some stuff with an image. As I want to do the changes on-the-fly, I pass the fileUpload instance from my HTML-form to a python script. The script calls a external method. The external method uses PIL to convert the fielUpload instance to a PIL.Image.Image instance, does some stuff and returns the PIL.Image.Image instance to the python script. In the script I want to save the returned object as an Zope image object using manage_addImage(). But the manage_addImage method expects a file object, not a PIL.Image.Image. Here’s the traceback Traceback (innermost last): • Module ZPublisher.Publish, line 98, in publish • Module ZPublisher.mapply, line 88, in mapply • Module ZPublisher.Publish, line 39, in call_object • Module Shared.DC.Scripts.Bindings, line 252, in __call__ • Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec • Module Products.PythonScripts.PythonScript, line 314, in _exec • Module Script (Python), line 13, in check <PythonScript at /test/autoimage/check> Line 13 • Module OFS.Image, line 589, in manage_addImage • Module OFS.Image, line 434, in manage_upload • Module OFS.Image, line 469, in _read_data AttributeError: Image instance has no attribute 'read' How do I convert the image object back to a file object so I can add it to Zope? Regards Christoph

VHM limits?
by Jaroslav Lukesh 14 Nov '03

14 Nov '03

Hi all, I have some questions, before i make some thousands (really!) VMH mappings to my server because I dont want to shut-out my zope loveliness... 1/ how much virtual servers could have single VHM mapping, or it have some size limit (eg., 64kB) 2/ it si possible to have multiple VHM objests in zope root (ie., one per set, for example vhm_A, vhm_B, vhm_C...) 3/ it is possible to place VHM objects into some folderish object (ie., Folder, Transparent Folder) for better organisation? Many thanks, JL.

Help for Newbie
by Ben Shaffer 14 Nov '03

14 Nov '03

I have started to use Zope using <dtml> tags, but have soon found that that does not fulfill all of my purposes. Through further research I have found that Python can also be used, and have learnt Python. My problem with Zope so far, is that although the zope.org documentation so far is fairly comprehensive, what I would really find useful, is documentation with examples. Is this available anywhere? Even if it was not on everything, but just the basics, it would be extremely useful. If someone could email a quick explanation of how to integrate Python with <dtml> tags that would also be extremely useful. Hoping that I am at the frustrating start of a blissful journey, Ben

Anyone looking at DreamFactory
by Brad Clements 14 Nov '03

14 Nov '03

I came across the DreamFactory product from Salesforce.com. I'm wondering if anyone else has considered it for 'thin client' development. Its like IBM's Sash project, but much simpler. -- Brad Clements, bkc(a)murkworks.com (315)268-1000 http://www.murkworks.com (315)268-9812 Fax http://www.wecanstopspam.org/ AOL-IM: BKClements

Re: [Zope] Adding users programmatically!
by Ibrahim Mubarak 14 Nov '03

14 Nov '03

> I figure the password is a field that contains the crypted pass and the crypting method. > > You insert only a plain password (without crypting) and i think that is the problem. > > You can review how Plone join new users into the acl_users folder. This is a follow up to my previous message in case my problem and solution can help someone somewhere :) Thank you, Manuel Saelices, for your response. However, the problem was not that I was passing the password as plain text. I made AccessControl/User.py spit out the password before and after the encryption process and it always stayed as plain text, even when adding users manually. After looking more closely at my Zope instance, I came across portal_registration and its API. I ended up using portal_registration.addMember. As an extra, it also creates the member's folder that contains their files and pictures (for use in forums). But why does addMember work and not userFolderAddUser, beats me.
