I also had a problem with ZSyncer 0.6 on a Zope 2.6.2 installation and I was attempting to do a sync with another Zope (plone) 2.6.2. I fixed the problem as follows (I can't promise this is a good fix, as it's a quickie but it seems to be OK): Around like 571 replace the code that looks like: full = obj.absolute_url_path() with try: full = obj.absolute_url_path() except: # absolute_url_path and virtual_url_path just don't work # in a apache proxy-vhm-zope situation, apparently. full = re.sub(r'.*?//.*?/',r'/',obj.absolute_url()) Greg Dudek > > > Syncing from A to B doesn't work at all.

acquisition
by Jason Leach 18 Nov '04

18 Nov '04

hi, So I have a cookie crumblier login manager. If I call a page that accesses login manager the macro/ZPT (through acquisition) references all my pages as: www.foo.com/login/mypage and www.foo.com/login/otherpage. I suppose its fry my references like href="mypage" in the Macro/Template. Do I need to fully qualify all the references with href="www.foo.com/mypage"? Jason.

Performance Zope & Caching with Squid
by Gregor Melhorn 18 Nov '04

18 Nov '04

Hello Zope-Users, First: I really don't know much about squid for now. Second: I've got the following problem on Zope Caching: My site has a high number of concurrent, authenticated users, that need to view private content (that's some kind of "worst case", isn't it? *G*). There is some frequently accessed content that may not be viewed by anonymous users, but is static to many authenticated users. Obvious solution would be using a RAM Cache manager, I suppose, so authorization is still done. Wouldn't it be faster to have the content cached by a proxy, taking the load from my ZEO-Clients (that would effectively only serve the same page over and over again)? Is it possible to somehow change the cookie user information that is submitted to Squid, so squid performs an authentication by itself? So I'd declare these (read-only) pages as cacheable, and Squid performs authentication before content is served. Is it possible to use Squid for ssl-encryption? Thanks in advance. Gregor

Thanks, I hadn't thought of that - tried it, but still get the error. It is reported as a TALES attribute error but I think that is just what bubbles up from whatever error is generated in the python script when it tries to do: print(item.art_image()) > Finally, you should re-think doing HTML in a script.

Yes, I know - unless as some say the TAL gets 'too' complicated or convoluted, in which case one 'should' move that logic to a python script - though perhaps not HTML generation. Anyhow...here is my situation: The number of items returned by a query will vary. So I need to generate a table with a fixed number of columns and a variable number of rows (last row not necessarily full). That is, a 2-D output, not just a 1-D list like in all the TAL 'repeat' examples I've ever seen or done so far. It was something I could figure out how to code in python. It was instant headache to try to code it in TAL. I am doing it with an explicit control variable in python - to know when to end one row and start another - and I don't know how that's possible in TAL. Is it? If someone can give an example in TAL of iterating over a variable number of items and generating a 2-D table with a fixed number of columns that would indeed be a more appropriate solution. thanks, John S. __________________________________ Do you Yahoo!?

PAFlow goes international
by Paolo Bizzarri 18 Nov '04

18 Nov '04

PAFlow is an open source software for document tracking and document management. It is currently being been developed following a series of requirements for the Italian public administration. Until now, PAFlow has been mainly an italian project. Even if it is used in several different public administrations here in Italy, we would love to have it used in an international contest. Also, we would like to take a more "open development" approach to the whole project. As such, we have done a couple of actions: - we have activated the mailing list "paflow-english", as current mailing list are in italian only. You can find it at: http://lists.sourceforge.net/lists/listinfo/paflow-english - we have provided a public CVS for the whole project, that mirrors our internal CVS every night. You can find it at: http://sourceforge.net/cvs/?group_id=7171. The web site for the project (currently in Italian only) is available at www.paflow.it. You can also download and try the latest version from the web site. We will try to provide more material as soon as possible. We are anyway open to input from other people. We really hope this project could be of interest for Zope users, and to find people interested in cooperating with us. Anyway now PAFLow is out in the wild. Regards.

Syncing Zope 2.6.1 to 2.7.3
by Ulrich Wisser 18 Nov '04

18 Nov '04

Hi, I really tried to get this working, but it feels a bit strange. I have two Zope instances: A: Zope 2.6.1 (binary release, python 2.1, linux2-x86), python 2.1.3, linux2 B: Zope 2.7.3-0, python 2.3.3, linux2 I installed ZSyncer 0.6.0 on both machines. When I try to sync from B to A everything works fine. Syncing from A to B doesn't work at all. When I try to open the "Sync" page I get an error immediately. (Please find the error messages below.) Any advice would be appreciated. I already tried to filter meta types. I did not change the default meta type selection. I am out of ideas. Ulrich # Whoops, Error!

image objects into table via python script
by John Schinnerer 18 Nov '04

18 Nov '04

Hello, I am using a python script to generate an HTML table structure. The script is called from a page template, like this: The script (renderTable) iterates over items returned from a catalog query which is passed one parameter. To put for example a date or string property in the table is easy, like this: ... for item in resultItems: print("<td>") print(item.creation_date.strftime('%B %Y')) print("</td>") ... return printed What I really need to put in the table, though, are Image objects that are part of the objects returned. How can I put the Image object into the table structure returned by the script, so that the Image object will render itself as usual? That is, as it would in for example: The below of course does not work (art_image is an Image object in the item object) - it gives a TALES attribute error on art_image: ... for item in BGitems: print("<td>") print(item.art_image) print("</td>") ... return printed ...and I am stuck on how to get the art_image Image object into the table returned by the script. thanks, John S. __________________________________ Do you Yahoo!?

If the previous answers did not give you what you want: You need to put the image tag in the printout: for item in resultItems: print '<td>' print '<img src="%s" width="%s" height="%s" alt="%s">' % (item.urloftheimage, item.width, item.height, item.caption) print '</td>' ... return printed Just remember that images are fetched after the page is rendered, so you should get a page even if the image url is wrong. You need to make sure that the query is returning your image object, not just its id.

First, and I think you know this, recall that you're not including the Image object, but rather an HTML 'img' tag that will display the image. There could be any number of problems, but make sure that what you think has an Image object in context actually does. Are you sure that you're not being given a BLOB or a name? To get the tag rendered from an Image, you can call the image. So put a pair of parentheses on the end of the name. This should be the exact same effect as the 'tag' method. (I do this by memory, so don't take it as gospel.) Finally, you should re-think doing HTML in a script. That's really what templates are for. You can use scripts for creating the list of items or doing complex transformations, but actually creating the HTML is not usually recommended. --jcc
