Accessing Files within Zope?
by Dianne Van Dulken 05 Jul '02

05 Jul '02

Hi all, I have just set up a folder which is designed to contain details of all our users. I've set up a ZClass for these users. The problem I am having is the transferance from our old system to our new one. I have a file containing all the email addresses of the old users (which is all I need initially), one per line, and want to write a script that steps through this file and processes the users into the Zope interface. The problem I am having is that I am finding it impossible to actually open the file within zope so you can actually use it. I've tried scripting with filein = open(file) But that never actually worked. I've tried it in Zope methods with "<dtml-in "_.getitem(file).split('\n')"> But that assumes it is a string (I admit, it was wishful thinking when I tried that). Does anyone know of a way to read a text file, contained in zope, and step through it? I've looked in the archives, and not found a way. Thanks! Di

nope, wasn't that :) I'm actually following the example from chapter 3 of Zope: Web Application Development and Content Management. the annoying thing is that I've tried it three times now, triple++ checked everything. and it's worked once, and failed twice. zope wrote: > i don't know if this will fix it, but you might try naming the product > CalendarEvent and the class calendarEvent, so there is a distinct > namespace between them. > m > > -----Original Message----- > *From:* zope-admin(a)zope.org [mailto:zope-admin@zope.org]*On Behalf > Of* Ben Avery > *Sent:* Friday, July 05, 2002 9:07 AM > *To:* zope(a)zope.org > *Subject:* [Zope] simple z-class problem > > Hi, > > I'm having intermittent problems with the simplest z-class within > a new product, through the ZMI. > I'm going through the stages of > > 1) I create a new product, CalendarEvent. > 2) inside Test, I create a z-class, id: CalendarEvent. > 3) inside this, I add some property sheet with some properties > through the properties tab. > 4) finally, I change the default view to > propertysheets/Prop/manage from the dropdown list. > > Now when I try to create an instance of it in a development > folder, I get the constructor form, but then a NameError: > *Error Type: NameError* > *Error Value: global name 'CalendarEvent' is not defined* > trace below: > >Traceback (innermost last): > File /export/home/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 150, in publish_module > File /export/home/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 114, in publish > File /export/home/Zope-2.5.1/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook > (Object: CalendarEvent_factory) > File /export/home/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 98, in publish > File /export/home/Zope-2.5.1/lib/python/ZPublisher/mapply.py, line 88, in mapply > (Object: CalendarEvent_add) > File /export/home/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 39, in call_object > (Object: CalendarEvent_add) > File /export/home/Zope-2.5.1/lib/python/OFS/DTMLMethod.py, line 127, in __call__ > (Object: CalendarEvent_add) > File /export/home/Zope-2.5.1/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ > (Object: CalendarEvent_add) > File /export/home/Zope-2.5.1/lib/python/DocumentTemplate/DT_With.py, line 61, in render > (Object: CalendarEvent.createInObjectManager(REQUEST['id'], REQUEST)) > File /export/home/Zope-2.5.1/lib/python/DocumentTemplate/DT_Util.py, line 159, in eval > (Object: CalendarEvent.createInObjectManager(REQUEST['id'], REQUEST)) > (Info: REQUEST) > File <string>, line 2, in f >NameError: (see above) > > > > I have done this exact procedure before, with success.

You have access to all of Python in an External Method. You can write a nonce program to read the file and construct dtml document or documents. You can install a product like External File or Local File System which provides direct access to the files in Zope. The files behave as DTML documents.

Upload, read() and a rather unexpected persistence
by Milos Prudek 05 Jul '02

05 Jul '02

Hi, I just found out that it is impossible to use File.read(20000) twice even in separate scripts, because Zope remembers the file position. Therefore data must be saved in the same Python Script that checks for validity and the data distilled from File.read must be saved elsewhere, if the saving procedure would use File.read again. Details: HTTP upload files may be checked via simple routine: fault=[] for F in files: Ft = context.filetype(F.file.read(20000)) # filetype is External method that calls UNIX's file command if Ft.find('GIF image data')==-1: fault.append('Not an image'.) But it is impossible to use F.file.read(20000) in a second script whose execution follows, because Zope remembers the 20000 position and will start reading at position 20001. Is this a feature (persistence), or a bug? -- Milos Prudek

Hi alienoid, > What I have to do to start Zope automatically from /etc/rc.d/init.d? > Thanks in advance I don't know how you do it there, but you can try the following line at the end of your "/etc/inittab" file: zp:2345:respawn:/usr/local/Zope/start It works and restarts zope if it crashes for some reason. Regards, Josef.
