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

BASE2 is one of a family of variables defined by Zope.

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

I can recommend the Zope book (-> zope.org) and URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html as background reading. Dieter

The wonder is that it every worked. >Fix up your html first, get it working without style sheets or javascript, >then add in a simple style sheet and get it working. >Then you can try to create the real style sheet you want. 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

Sure. You would need an External Method and either the Python modules "urllib" or "httplib" or the Python module "ZPublisher.Client". This gives you the HTTP part. Modern Zope distributions contain a "pyexpat" module, see below the "Shared" package. This will allow the XML parsing. > Id like to then be able to write it to *my* database using a ZSQL method.. It appears that you do not need to go through Zope for that. An external Python script should be able to do it, too. Dieter
