Storing many large objects in many folders
by Christoph Schmitz 10 Dec '02

10 Dec '02

Hi, I need to store many large objects (30+MB video files) in a way that Zope can serve them; plus, these files should be distributed over a large folder tree /mytree/... in my Zope system. We've considered the following options: - use LocalFS; the problem is that I'd like to avoid having a LocalFS object in every folder of /mytree/..., and I neither want to put all the files into one filesystem directory; so I'd need some solution that automatically maintains the logical structure of /mytree/... in the filesystem directory. - use BLOBs on a RDBMS; unfortunately, I couldn't get the DBMS connection we are using (DB2 via SQLRelay) to work correctly with BLOBs; I've considered http://www.zope.org/Members/peterb/oracle_lobs, but without success. Are there any viable alternatives apart from these two? What do other people use when they have to maintain large numbers of large objects? Thanks in advance, Christoph -- -- Christoph Schmitz <cschm(a)REMOVEMEgmx.de>

You should really direct your questions to the list, not to me. I'm cc'ing the list.

Look at the html source, inside the quotes. I bet you'll see <ZPublisher.HTTPRequest.FileUpload instance at e41414> > form > filex <ZPublisher.HTTPRequest.FileUpload instance at e41414> > > > How can I find the name and the path of the filex? Name: filex.filename Path: I don't think you can. But you might have a look at filex.headers, maybe there's something useful in there.

user folder question
by ben＠thesite.org 10 Dec '02

10 Dec '02

I'm having a problem with user folder permissions: I have one acl_users folder at the root folder of a website, www.mysite.org, using Cookie Crumbler I also have an acl_users folder in parallel to this, allowing access to an XML-RPC application server area. I need to keep them separate, or failed XML-RPC authentications are picked up by the Cookie Crumbler code, and the XML-RPC client gets the login_form html page sent back! I need to let certain users of the website create user accounts in the xml-rpc server area. I have a user role, hq_user, who creates the user in the xml-rpc area. The permissions on the xml-rpc root directory grant hq_user the manage_users permission. But when I try to add users in this other acl_users folder, I get an error that it is not allowed. But this user, if I change the code, can create users in its "own" acl_users folder. The hq_user role is created in the root directory above both the acl_users folders in question. the python code: context.xmlrpcfolder.acl_users.userFolderAddUser(name=f_username, password=f_pwd, roles=['c_lcp'], domains=()) can anyone shed light on this? what permissions do I have to set to add a user to an acl_folder? TIA Ben Avery (zope 2.6.0, pyth 2.1.3, solaris 2.7)

ZODB / SQL question
by Michael 10 Dec '02

10 Dec '02

Is there some documentation on how to migrate from an existing ZODB application to SQL? I seem to only find info on setting up and using one or the other, but now how to switch from one to the other. Any pointers would be appreciated. Michael

dynamic resize of image?
by Kelley, Sean 10 Dec '02

10 Dec '02

I have some images in a btree folder that get added by users. How do I show those images in a smaller size easily on a search results page? It would be nice to some way specify the default size in width such as 50 pixels etc.

Paul, If I had not figured it out myself at about the same time you were writing your reply, you would have saved my evening! Thank you very much! I hope I speak for all of us in need of help on this list in thanking all of you Zope masters for taking the time to answer our questions.

ZPT standard_error_message not finding methods
by Felix Ulrich-Oltean 10 Dec '02

10 Dec '02

Hi I'm trying to write a standard_error_message page in ZPT and attach it to my class. In my class definition I have: standard_error_message = PageTemplateFile('html/error_page.html', globals()) and manage_master = PageTemplateFile('html/master_page.html', globals()) in error_page.html I have: <p tal:content="exists:container/manage_master" /> Now, this returns true: http://localhost:8080/sites/myClassInstance/standard_error_message but this returns false: http://localhost:8080/sites/myClassInstance/some_nonexistent_page There are also other methods that are found when calling standard_error_message explicitly, but not when it's called as a result of an error. What am I missing about how standard_error_message is called? TIA Felix.

TAL that kills
by David Bear 10 Dec '02

10 Dec '02

Interesting problem. IN a ZPT the following TAL will always kill the Zserver processes. <p tal:repeat="doc container/docStore"> <a tal:attributes="href doc/getId" tal:content="doc/title_or_id">document </a> </p> any idea why? This is Zope 2.5.1 running on python 2.1.1 on FreeBSD. I've done a littl tal and none of it has caused zope to die like this.
