This is just normal python. When you want to assign to a global variable inside a function, you have to declare the variable as a global: _stateVariable = 0 class def func() >>> global _stateVariable _stateVariable = 1 -Randy -----Original Message----- From: Andrew Athan [mailto:aathan-zope-list%REMOVEME@memeplex.com] Sent: Friday, April 06, 2001 1:01 PM To: zope(a)zope.org Subject: RE: [Zope] Verrryy strange behavior (NameError) I'm sending this in case my sagga helps some other relative newcomer. I suspect this problem has something to do with python1.5.2's (or Zope's hackery of...) handling of namespaces within modules & classes. What I needed was access to a "static global" variable to store some state for me. (No, I haven't looked into threads, their existance, or such issues in Zope). What I was doing was: _stateVariable=0 .... class .... def fun() .... _stateVariable=1 and this was causing me all kinds of grief. By changing the code to _stateVariable = {'a':0} ... class ... def fun() ... _stateVariable['a']=1 everything works just fine. Now, can someone give me the shortcut to understand WHHHYYY? A.

Now, can someone give me the shortcut to > understand WHHHYYY? When Python sees an assignment to a *variable*, it assumes you want to define a new *local* variable. You must explicitly declare it "global" to be able to change the value of a global variable from a local context. In the second case, you do not assign to a variable, but modify an object (leaving all variable binding unchanged). Dieter

Re: [Zope] html quote of property sheets

Pierre-Julien Grizel writes: > If I type for example "<" in the title property of a DTML Document, it is > showed as "<" when I valid the property form. As you have probably guessed, the corresponding DTML object lacks a "html_quote". A further (even better) alternative would be to use the entity syntax. How about locating the object, fixing it and sending a bug report with patch into the Collector? Dieter

The intranet site Craig Stoddart has described incorporates HTML documents created with StarOffice, which automatically creates its own HTML, DOCTYPE and Head elements. The problem is not unique to StarOffice - most other HTML editing tools will cause similar problems. When the HTML document is wrapped up with standard_html_header and standard_html_footer, the problem being experienced by Craig will appear. If Craig deletes the superflous HTML elements (HEAD etc...) from the StarOffice document , they will re-appear the next time the document is updated via StarOffice. I think the answer is to write a dtml or Python method which will only display the HTML be displayed in the browser ie between the <BODY> and </BODY> tag. Although I think this is the answer, I am not sure how to achieve it. Has anyone else written similar code? John Lawson

Maybe, you fetch an unexpected "file" from somewhere that does not have a "filename" attribute. Replace "file" by "REQUEST.form['file']" in the "manage_upload". If it does not help, we need (at least) the last part of the traceback. Dieter
