Small bug in DTMLFile
by palomar＠sg.uji.es 27 Sep '01

27 Sep '01

Hello, (I think) there's a very small bug in 'App/special_dtml.py'. In Zope 2.4.1, the line 231 is: if bind_to in ('container', 'client'): I think it should be: if bind_to in ('container', 'context'): The problem shows when subclassing DTMLFile and trying to change the value of "_Bindings_client". The bug is also in the CVS. jdavid

Z2.log file not showing user name correctly
by George Nguyen 27 Sep '01

27 Sep '01

I was looking in the entries in the Z2.log file and it lists the user as being "Anonymous" when I'm actually logged in as a validated user. I'm using the LDAPLoginAdapter for my top-level acl_users. I have no other acl_users folders. Any comments? George __________________________________________________ Do You Yahoo!? Get email alerts & NEW webcam video instant messaging with Yahoo!

update Zcatalog
by Johan Beauce 27 Sep '01

27 Sep '01

Hello, I use Zcatalog to index my file. This file change often. They are deleted, added or modified. I have two choices to update my ZCatalog : first when I add a file, I add the file to the catalog (but it doesn't work) <dtml-let docAdding="_.getattr(PARENTS[0], idName)"> <dtml-call "companyDoc.catalog.catalog_object(docAdding,_.string.join(docAdding.getPhys icalPath(),'/'))"> </dtml-let> when I delete a file, I delete the file from the catalog (but it doesn't work) <dtml-let docAdding="_.getattr(PARENTS[0], idName)"> <dtml-call "companyDoc.catalog.uncatalog_object(_.string.join(docAdding.getPhysicalPath (),'/'))"> </dtml-let> second clear the catalog, and create all indexes in catalog again. <dtml-tree> <dtml-if "objectValues(['File'])"> <dtml-call "companyDoc.catalog.catalog_object(id,_.string.join(docAdding.getPhysicalPat h(),'/'))" </dtml-if> </dtml-tree> Can you help me to this two solutions work please ?

Adding a permission to an ObjectManager derived ZCLass
by Michael R. Bernstein 27 Sep '01

27 Sep '01

Hi all, I posted this 24 hours ago on the main zope list, but didn't receive a response, so I'm reposting here. I've got an ObjectManager and Folder derived ZClass that contains instances of a second rather simple ZClass. It works fine, the Manager role can access the management interface of the container, add edit and delete instances of the contained ZClass, and Anonymous can view index_html. Now, I am trying to add a permission to the container ZClass that will let a user with a specialized role that has the permission view the management interface (the 'Contents' tab) of the container and add, edit, or delete the simple ZClass instances in the container. The container doesn't have any property sheets, but the simple ZClass does. Does anyone have a simple walkthrough of what I need to do? The Zope Book only discusses adding a permission to control access to a Property Sheet. Thanks in advance, Michael Bernstein.

Distributing Zope & one of our products
by Simon Coles 26 Sep '01

26 Sep '01

Hi, You may know that as well as doing Cool Things With Zope, we also do stuff with Electronic Lab Notebooks (ELNs) - not using Zope unfortunately, but that's another story. Anyway, we have come up with an Open Source ELN (OS-ELN), which is based on Zope and the CMF. Readers of this forum will not be surprised to know that it didn't take much to turn Zope + CMF into quite a nice little ELN. For the curious, you can download what we have at http://www.opensourceeln.org/ What we're trying to do is make this thing approachable for people who don't know Zope, and indeed are somewhat unfamiliar with installing Open Source stuff on their machines. Our primary target for a more approachable install is Windows users, as we feel Linux users are probably going to be OK with a more manual install. The ideal would be to have single file they double click to install, answer a couple of simple questions in the install process, and then point their browser at their running ELN. Kind of like the existing Zope for Windows binary install... But of course at the moment we have to get them to: - install Zope - get, expand, and install the CMF (which is distributed as a .tgz, rather confounding Windows users) - get our product and expand/install it - then log in as the inituser, create a normal user, log out, log back in, create an ELN, then log out, then access the ELN, and join in the normal CMF fashion What I'd like to do is customise the existing Zope installer to include the CMF and our OS-ELN, and to have an already-setup Data.fs. That would really reduce the amount of work someone had to do to download and start playing with this, and of course once they've had a play they may well decide to invest more time in learning Zope and setting up a proper server for production use. Does anyone have any thoughts as to the desirability of this, and the best way of doing it? (BTW, I've always felt that "products" like Squishdot would really benefit from something like this as well. Maybe when Chris sees how easy this is to do for the OS-ELN.... ;-) Thanks for any help, Simon --------- My opinions are my own, NIP's opinions are theirs ---------- Simon J.

Acquisition, __getattr__ and making a Proxy/Symlink class
by Lupus Yonderboy 26 Sep '01

26 Sep '01

Hi folks, I'm having some troubles trying to develop a particular zope object and would really appreciate a bit of help. I'll explain what I'm trying to do: What we have is a tree of nodes rooted in a folder (excuse my ascii art) like so: + DocumentRoot (folder) + a + b + c + d + e + e + f + g + X (proxy, pointing to 'e') Here [a-g] are our node objects, and X is a proxy-object. The proxy-object is intended to behave a bit like a sybolic link with a few extra features. I have looked at Shane Hathaway's Symlink product, which does the linking job just fine. It allows us to create a proxy that behaves just like the target, but we also need the proxy-object to have it's own attributes and methods. In the above hierachy, the desired way of finding an attribute of the proxy 'X' goes something like: - look in the proxy object ('X') - if not there look in the proxy target ('e') - (maybe) if still not found acquire from aq_parent ('g') - otherwise raise AttributeError I guess we are wanting X to behave as though it were a child of the object it links to, so X always behaves as though it were X.__of__(e) (and possibly also a child of g, ((X o g) o e) or ((X o e) o g) if not too complicated). I have tried hooking __getattr__ and have a hard time avoiding recursion; I have taken a look at the ever-productive Shane Hathaway's TransparentFolder product as well but I think I am let down by my lack of understanding of the particulars of acquisition. Can anyone shed some light on how i might do this? All objects under the DocumentRoot will be derived from one of our base classes, so if we need to override __getattr__ as per TransparentFolders it can be done easily.

zLog and stderr
by Toby Dickenson 26 Sep '01

26 Sep '01

I have some old python modules which are generating messages from the new python 2.1 warning framework. I can easily fix these modules, however it has exposed a problem in Zope...... The warning framework tries to write to sys.stderr, and my Zope is dying from an exception because stderr has been closed. I think it makes sense that Zope should replace sys.stderr with an object that sends messages to zLog, however zLog itself sometimes wites to sys.stderr. Any thoughts on the right way to fix this?
