default webpage after External Method script executed
by Alan 20 Jul '06

20 Jul '06

Hi! My simple webpage for submitting files is ok. It calls a External Method script to do all the dirty job. However, I am running out of ideas of how to get back to my default submitting web page after submitting a file (and thus execute the script). Any idea would be very welcome. Thanks in advance.

I'm trying to get a handle on Zope and don't understand the rational behind the manage_changeProperties() method. Why, given an object called myObject with a title property, can I not change the title by saying simply: myObject.title='The new title'

Although I wonder why there is no more direct method to do this, this works well. Cheers, Eric

Garito, please reread Andreas words. They are wisdom of the masters and not to be ignored. What would you want to catalog from the Page Template? The <html>, <body> and <div> tags? The tal:content attributes? Not these? But there is nothing else in there. There should be *no* content in the page template. If there is then *you are doing something wrong* and you will pay a heavy price down the road. Stop what you are doing and think about doing it in a better way. Regards, Sascha

ExternalFile - getting back the file
by krokodylek＠tenbit.pl 20 Jul '06

20 Jul '06

Hi :-) I'm using the ExternalFile product: http://www.zope.org/Members/arielpartners/ExternalFile because I need to have a file both in ZMI, as well as in filesystem. I would like to ask if anyone can tell me how to get back the file that ExternalFile was created from, having only the object? In fact I do not need the file itself, but tha data (bytes) that were inside. I would be very grateful for any help. Best regards, Maciej Zieba

Reading and parsing a text file object
by egf05＠doc.ic.ac.uk 19 Jul '06

19 Jul '06

Hi, I am new to Zope (but familiar with Python) and have a question. I have a text file in a folder and I would like to parse its content, and I wanted to put the text in a string variable. I understand I can access the content through file.data or better str(file.data). However, the string I obtain has no carriage returns anymore, they are replaced by a space. This is annoying because I cannot split the file line by line. Is there a "trick" I do not know? Or is there a better way to parse the content of a text file object? Any advice would be very appreciated. Thanks, Eric

Using the DTML REQUEST Object
by Muk Yan 19 Jul '06

19 Jul '06

Dear Exalted Sirs and Madams, I'm a Zope newbie, so be gentle. I'm using DTML on Zope (yes I know Plone and Tal is now the norm) and I was wondering if regularly using the REQUEST(set and get) object is bad practice. I'm mostly a C++ programmer and I know of the horrors of global variables, but I was wondering if there was any way to pass information from DTML Documents to DTML Methods and vice versa (and maybe from DTML Methods to DTML Methods) without using the REQUEST object. Thanks and take care, Muk Yan

Re: [Zope] external method with import tarfile

Hi there! I managed to find the problem and the solution. First, I've forgot to mention that in my script, oname is an uploaded file. I just inserted a f.close() and voilá! def upload_external(self,file,REQUEST): import os,tarfile ... f=open(oname,"wb") f.write(file.read()) f.close() ... tar = tarfile.open(oname,"r:gz") for itar in tar: tar.extract(itar.name,jobdir) return "Done" Cheers, Alan On 18/07/06, Alan <alanwilter(a)gmail.com> wrote: > Thanks for your reply. > > Yes, my script works and my file are not broken.
