how to download big files using zope?
by Yuppie 07 Oct '02

07 Oct '02

Hi! I have some big files (about 500 MB) in the filesystem on the server and want to make them downloadable. I could do something like this, but it loads the file into memory: <code> def manage_download(self, REQUEST): myfile = open('myfile.bin', 'rb') filestring = myfile.read() myfile.close() REQUEST.RESPONSE.setHeader('Content-type', 'application/data') REQUEST.RESPONSE.setHeader('Content-Disposition', 'inline;filename=myfile.bin') return filestring </code> Is there a way to just pass the file through? Without loading it in a string or in the ZODB? Any hints are welcome. TIA, Yuppie

Export/Import problem (...object broken doesn't...)
by sara 07 Oct '02

Hi! I am a beginner in this Zope world. I am having a problem and I could't find the solution searching the MLs archives. I have exported a folder from my company Zope environment and I am trying to import it to my home one, but all I get is: The object broken doesn't support this operation The error stack ends with: path/CopySupport.py line 373 in _verifyObjectPaste Copy Error: (see above) Each time that I import/export from/to the same machine I don't experiment any problem, so I don't understand why my home Zope thinks that the company zexp contains broke object(s). Does anybody have a clue on what is going on? Thanks! Sara

mailhost location problem
by Ben Avery 07 Oct '02

07 Oct '02

Hi, since restructuring my zope objects to tidy up the project's root folder, I've been able to get objects working, but others not. I have put things like some zsql and python methods in a folder called 'helpers', so I can call a python method which spits out a dropdown HTML element, from any page as <dtml-var "helpers.category_dropdown()"> but I can't seem to make a <dtml-sendmail ..> tag work, however I refer to the mailhost object living in helpers. I've tried <dtml-sendmail mailhost="helpers/MailHost">, helpers.MailHost, and everything else I can think of, but it complains it still can't find it. Could anyone tell me how to refer to this mailhost object? TIA Ben Avery YouthNet UK (p.s. Zope 2.5.1, Python 2.1.3, Solaris 7)

Hi I have a home-made python product.

(/sites/beta.xx.com/style) The following works: - ttw editing of the Folder objects - FTP access to my class of objects, even nested ones - adding a folder ttw to an instance of my class - ftp access works Where can I start figuring this out?

Releasing a database connection automatically
by Florian Reiser 07 Oct '02

07 Oct '02

Hello, I'm using VFP7 over ODBC as database backend. However VFP7 is not only the database backend, but still has a application running on the same data zope uses. Some functionality which is built into the VFP7 appliction (like database reorg) requires that the VFP application gets exclusive access to the data. When I'm running zope on them, then I first have to stop it and after the action took place to start it again. Is it possible to signal zope that it should release the database connection, so the action could take place? After that, if zope gets the next request, it would open the database connection again. Thanx Florian Reiser Tel: +49 (0)7351 37 27 57 Fax: +49 (0)7351 37 27 59 E-Mail: florian.reiser(a)ra-bc.de

Bug in sendmail tag?
by Cornelis J. de Brabander 07 Oct '02

Hi all, I'm stuck with the following code. In zope 2.5.1 this code results in an attribute error with error value 'sendall'. In zope 2.4.3 it works. I've noticed there are differences in smtplib.py between the two versions. But the code I use is correct according two the DTML Reference. Is this a bug? <dtml-sendmail mailhost="MailHost"> To: 'brabander(a)fsw.leidenuniv.nl' From: 'brabander(a)fsw.leidenuniv.nl' Subject: 'foo' bar </dtml-sendmail> Traceback (innermost last): File E:\zope\251\lib\python\ZPublisher\Publish.py, line 150, in publish_module File E:\zope\251\lib\python\ZPublisher\Publish.py, line 114, in publish File E:\zope\251\lib\python\Zope\__init__.py, line 159, in zpublisher_exception_hook (Object: mailtest) File E:\zope\251\lib\python\ZPublisher\Publish.py, line 98, in publish File E:\zope\251\lib\python\ZPublisher\mapply.py, line 88, in mapply (Object: Mailer) File E:\zope\251\lib\python\ZPublisher\Publish.py, line 39, in call_object (Object: Mailer) File E:\zope\251\lib\python\OFS\DTMLMethod.py, line 127, in __call__ (Object: Mailer) File E:\zope\251\lib\python\DocumentTemplate\DT_String.py, line 473, in __call__ (Object: Mailer) File E:\zope\251\lib\python\Products\MailHost\SendMailTag.py, line 116, in render (Object: MailHost) File E:\zope\251\lib\python\Products\MailHost\MailHost.py, line 156, in send (Object: MailHost) File E:\zope\251\lib\python\Products\MailHost\MailHost.py, line 201, in _send (Object: MailHost) File E:\zope\251\bin\lib\smtplib.py, line 466, in sendmail File E:\zope\251\bin\lib\smtplib.py, line 316, in ehlo File E:\zope\251\bin\lib\smtplib.py, line 247, in putcmd File E:\zope\251\bin\lib\smtplib.py, line 235, in send File <string>, line 1, in sendall AttributeError: (see above)
