images and HTML code in a product
by Gregory Popovitch 04 Aug '01

04 Aug '01

I'm quite new with Zope, so I apologize if this question is trivial. I am writing a product which generates HTML pages with references to a large number of images and HTML files. I would rather not duplicate these images and files in each instance of the product, but have them reside in the 'Products' directory itself. How can I 'publish' these files from the 'Products' directory, so that they can be found by every product instance through the acquisition process. gregory (greg(a)gpy.com)

[Q] How to get "Owner" access to work properly?
by Asko Seeba 04 Aug '01

04 Aug '01

Hi, I'm new in this Zope thing and sorry, if I ask a boring old question, but I didn't find any FAQ and this mailinglist here is my last hope :). CONFIGURATION 1. So, I downloaded Zope 2.4.0 binary executable package for windows and installed it on win2000. 2. I (with manager rights at manager page) made a folder (say my_folder) for a web page, added an acl_users folder to this folder 3. I made the web page private by unchecking "Acquire permission settings?" checkbox from "View" permission and adding the checkbox to "Manager" role. 4. I added a special role for the my web page users into my_folder's Security tab, say "Author" with following permissions: Add Documents, Images, and Files Add Folders View 5. I added users alice and bob (two famous paranoics in security related literature) and made a simple file upload form with a possibility to also delete the upploaded files. PROBLEM I want to get the situation where each user can delete only these files that are uploaded by this user. I tried deleting with calling manage_delObjects from DTML document. 1. When I set up the checkbox for "Delete objects" _only_ to role "Author", then everyone with this role can delete the file, even those who are not owners of the file. 2. When I set up the checkbox for "Delete objects" _only_ to role "Owner", then nobody can delete the file, even the file owner. For example, when Bob uploads a file, then I can see from management page's ownership tab, that the file owner is Bob, but if Bob tries to delete the file, he gets a dialog box asking password (although he is already logged in as a Bob) and if clicking Cancel (using IE 5.50.4522.1800), he gets an error (see Appendix below). According to Zope documentation, the Owner's role should applie automatically for owned files, but here it doesn't work. Why?

File Upload returns "application/octet-stream", not correct type
by Joel Burton 04 Aug '01

04 Aug '01

This is possibly a browser error, rather than a Zope error, but I can't find any references on the web for a browser bug. When we upload to Zope (via a form that we build, or by simply adding a "File" object through the management interface), it comes out as "application/octet-stream" rather than as the appropriate MIME type. This only happens on one computer (Win 98, IE 4), suggesting a browser bug, but I can't find any references on the web about a problem with this. Does Zope do any mangling at all of MIME types? Does anyone have any ideas what this could be? Thanks for any help. -- Joel Burton <jburton(a)scw.org> Director of Information Systems, Support Center of Washington

Need help with a syntax error
by Steven Grimes 04 Aug '01

04 Aug '01

I have the following line of code inside a <dtml-in>: <dtml-call "REQUEST.set('tqry',Query.PoRpt.Aug01POquery(pormth=tpormth,pmth=07,pyear=20 01,sellid=_['sequence-item']))"> If I change the pmth variable to pmth=08 and try to save I get a syntax error. I only changed the 7 to an 8. That is the only character in the file I changed. Any help would be greatly appreciated.

Starting zope from a python script
by Chris Keyes 04 Aug '01

04 Aug '01

Hi All... I'm trying to write a Python script to control zope, basically it creates the instance home etc and so on and then fires up zope, checks for z2.pid and then prods zope and does some things to it... Thats all ok, fine etc... but I am writing a script that reverses the process if anything fails (it should never fail, but while I'm looking after it, things will inevitably go wrong) so... I want to be able to kill the Zope processes... Simple me thinks, I am using a -u to set the user so I can kill all the threads belonging to that user and the thing will die?? No, not quiet, the process that started the Zope instance keeps restarting it (most of the time this sounds like a great option but...) So I want to keep hold of the parent process ID so I can kill that, I think something like os.spawnv will let me do it, but it doesn't work under Linux :-( seems to be doze only... Anyone got any good ideas how to do this... I've just thought I can follow the parent PID links back from the user process, so that would be one way... Will go and try that, if anyone has any better (neater?) solutions I'd be grateful... Cheers Chris K

Problems with zclass and instances!!
by Edgardo Zulian 04 Aug '01

04 Aug '01

Hi there: I have created a product 'X' with a zclass call 'X1'. This X1 zclass in the propertysheet has a Common Instance Property Sheet called 'section' (/Control_Panel/Products/X/X1/propertysheets/common/section), with some properties with default values: ie. one of it's property is call ed 'section1' with the default value 'left side', the type of this property is 'string': section1 'left side' string Then in the views of the zclass I 've added a method "propertysheets/section/manage", so when I create an instance I can enter to this propertysheet. So the problem is here: When I create an instance of this 'X1' zclass an I enter to this propertysheet/section , I can change the default value of 'section1' which was 'left side' to 'center side' for example. But then if i change the original default value of my zclass 'X1' to 'right side' let say. The change will not be reflected in my instance, which is okey because i have change d the value to 'center side' before. Another case is when I create another instance of 'X1' zclass without making any change to the value of 'section1' and click on save changes, then if I change the default value in the zclass, the change will not be reflected in this instance. So the question is: There is a way to recognize when an instance will not take the changes that are make to the default values of a propertysheets (in this case thepropertysheet 'section' ) of a zclass from which they inheritance? I try with this lines in an external method, but nothing: self=self._getOb('instanceTest') # instanceTest is the name of the instance of the 'X1 Zclass' a=getattr(self,'meta_type') b=getattr(self.__class__,'meta_type') # in this example the answer was the same: X1 a=eval('self.__class__.propertysheets.section._propertyMap()') b=eval('self.propertysheets.section._propertyMap()') # the answer was again the same: {'id': 'section1', 'type': 'string','meta': {}, 'mode': 'w'} #I try acceding to the zclass to know if it was different from theinstance... a=eval('self.Control_Panel.Products.X.propertysheets.common.section.propertyMap()') # the answer not help: {'id': 'section1', 'type': 'string', 'meta': {}}, I cannot found any property or something that help me... I don't know where to look or what to try next....if anybody can help me with this....... Thanks in advance Edgardo

Bind error on Server Startup
by Eric Roby 03 Aug '01

03 Aug '01

I am trying to get Zope 2.3.3 up and running on a Sun server running the latest OS. I can start it up fine on port 8080 (or all ports I tried above 7000). However, I am unable to start it up on any lower ports (including port 80). The traceback message I get points the following def block in asyncore.py. def bind (self, addr): self.addr = addr return self.socket.bind (addr) The specific error I get is "bind error: (13, 'permission denied'). I have talked to the sys admin and everything is set correctly as far as access to bind or any other network resources are concerned. There are NO other resources on port 80 on this system. Anyone had similiar problems??

Newbie question
by David Lambert 03 Aug '01

03 Aug '01

I am currently browsing the API Reference section of the Zope book and am trying simple examples. I am puzzled as to how various methods may be accessed from dtml. For instance the line: <dtml-var expr="getSize()"> works fine, but: <dtml-var expr="dow()"> (which I would have expected to return the day of week) gives an error Obviously I am confused. Could somebody try and put me on the right tracks! TIA Dave.

How do I connect to a PostgreSQL database?
by Terry McKenna 03 Aug '01

03 Aug '01

All, I am trying to establish a connection to a PostgreSQL database but have had no luck with getting the database adapter to list in the "add" drop down. I really need a recommendation on which database adapter to use (it's for a help desk application) and how to install it in Zope. I tried a couple of them from the Zope products page but no luck. I was able to get MySQL to work but I need PostgreSQL. -Thanks in advance. __________________________________________________ Do You Yahoo!?
