It seems that a separate zope instance for each plone site is the way to go. Just a question: is it a problem for performance/bottleneck/big python lock?

Critical System Hosed, Plan B - upgrade zope, convert db
by Wes Modes 13 Apr '08

13 Apr '08

Okay, I accept that Zope is a mysterious god that requires sacrifice. And I wasn't able to solve the mysteries of how to get it up and running again with my old data after an unintentional "upgrade." However... I can upgrade Python from 2.4.2 to 2.4.4 and upgrade Zope from 2.7.2 to 2.10.5, get that working, and then hopefully convert my old data. I can handle the python and zope upgrades, but have no idea how to take my old zope database and use it with my brand new zope installation. Any ideas?

Database conversion
by Wes Modes 12 Apr '08

12 Apr '08

I am running Zope 2.10.5 I've just upgraded from Zope 2.7 I would like to move my database to the newly created instance. I followed the very reasonable and clear instructions here, http://svn.zope.org/*checkout*/Zope/trunk/doc/FAQ.txt (esentially, just moving the Data.fs file) However, the old data does not come up when I bring up the server again. Perhaps the old objects need conversion or some other juju? Any suggestions?

thank you so much thomas.. that was really very helpful. I'm starting to get the picture. As you have said, i am the data from the database not from the database. But i cannot understand the below Link code.. "<a href="http:/link/to/my/description/template/?my_recnum=<dtml-var drug_name_recnum>"><dtml-var my_drug_name></a>" Can you please elaborate on the code,, Am especially concerned about understanding the below line of code.. "a href="http:/link/to/my/descrip tion/template/?my_recnum=<dtml-var drug_name_recnum>" The example youo showed aptly suits my need. I use CSS and HTML i don't use pagetemplates. If you are willing can you please send me the code of how you are dynamically <a href>'ing the individual subjects. That will be more helpful.

the grand reunion
by Yuri 11 Apr '08

11 Apr '08

Hi! Actually I've two Plone "working envinronment" and one zope, each in a different machine: - one, with two zope 2.9 istances (one for developing), running both multiple Plone 2.5 instances - one, with zope 2.9, running multiple Plone 2.5 instances - one, with zope 2.7.9, running zope only applications We have bought "big iron" hardware now, where I can do almost everything (with a fiber channel network storage, multiple rack servers). tipically, I use one instance to develop, and one to deploy. This mean different zope instances which shares only the base, and having different products. I would like to have an easy way to develop without having to be subject to dependencies from other envinroment, minimize the effort to mantain it and focus on doing things :) Is one big zope installation, with multiple instances, well suited for this tasks? Or is better different zope versions? What about the various Data.fs, is better to have them separated by application or by zope envinroment? I mean all the Plone in a single Data.fs or each one in a separated Data.fs? So, what is the best approach to migrate the three servers?

retrieving a single column from database and giving it as hyper link fetching respective data
by member madhangc 11 Apr '08

11 Apr '08

Dear all, I'm developing a biological database using Zope 2.6 and pgsql. Let me explain my issue with an example. There is a menu called Drug in my homepage, by clicking the menu the drug names along with their type in two different columns get displayed in the body. I can do things till that. My problem is , lets say there is a link called "Isoniazid" with all other links(drug names) in it. When a user clicks one of the links as i said before as "isoniazid" only the information about isoniazid has to be retreived and displayed , likewise to all the other drug links. I have no idea how to capture the click event and the data to be retrieved. Can someone help. Thanks in advance. And another query, how can i select text from a dropdown box. I just need the data which is selected in the dropdown box and sent as query. Thanks again. -- Best Regards \madhan Things must be learned only to be unlearned again or, more likely, to be corrected. -- Richard Feynman

Dear list I'm trying to send a multi-part email after having submitted a form. In that form, the user will give some basic information from him, then he will be able to send at most three files. This is my dtml-method to send email after having submitted the data: <dtml-let email="REQUEST.get('aba_email_txt').encode('utf-8')" name="REQUEST.get('aau_name_txt').encode('utf-8')" lastName="REQUEST.get('aat_vorname_txt').encode('utf-8')" company="REQUEST.get('aas_firma_txt').encode('utf-8')" file1="REQUEST.get('aap_dateien_anhang_dat')" file2="REQUEST.get('aaq_dateien_anhang_dat')" file3="REQUEST.get('aar_dateien_anhang_dat')"> <dtml-sendmail smtphost="my_host.my_domain.com"> To: my_mail(a)my_domain.com From: &dtml-email; Subject: Anfrage &dtml-name; &dtml-lastName; - &dtml-company; Content-Type: text/html; charset=utf-8 <dtml-mime type="text/html; charset=utf-8"> <html> <body> Some html code comes here </body> </html> <dtml-boundary type="application/octet-stream" disposition="attachment" filename_expr="file1.filename" ><dtml-var "file1.read()"><dtml-boundary type="application/octet-stream" disposition="attachment" filename_expr="file2.filename" ><dtml-var "file2.read()"><dtml-boundary type="application/octet-stream" disposition="attachment" filename_expr="file3.filename" ><dtml-var "file3.read()"></dtml-mime> </dtml-sendmail> </dtml-let> Let's say that the user doesn't submit file3, on that case, zope will generate something like this: "some_ramdom_id.dat" and it will attach an empty file. I tried something like this: <dtml-if "file1.filename not in ['', None]"><dtml-boundary type="application/octet-stream" disposition="attachment" filename_expr="file1.filename" ><dtml-var "file1.read()"></dtml-if> However when I try to save, zope fails and says: """ Error Type: Document Template Parse Error Error Value: Unexpected tag, for tag <dtml-boundary type="application/octet-stream" disposition="attachment" filename_expr="file1.filename" >, on line 215 of sendAnfrage """ The only way I found to cope with this was doing a script to validate if a file has whether a name or not, then I will return a dictionary like this: {'name': real_name_or_dummy_name, 'data': <file.read()>_or_dummy_text} So, I feed the boundary with a dummy file when no file was uploaded. I don't really like to send dummy files since it may confuse the person receiving the emails. Is there any better way of achieving this? Please note that since I'm working in the zmi and I'm not the administrator of the machine where my page is hosted, I can only use dtml to send mail :-(, thus using the python mail library isn't an option on this case.
