Create image with PIL in Zope
by Bruno Miguel Silva 01 Oct '04

01 Oct '04

Hi, I have a small script that generate a image with some text, in python with Python Imagin Library (PIL). The problem is, i want a security image in an html page in zope, so i started to put the code in a External module, and now i have all kind of problems with that script. When i use the "ImageFont.load('pathToFont.pil')", that causes an Error Type: IOError Error Value: cannot find glyph data file i don' understand, because i have the ".pbm", and it works in command line. So, then i try to do "ImageFont.load_path('font.pil')", and that causes a Error Type: IOError Error Value: cannot find font file once again i couldn't understand because it works on command line, because the font file is in "/usr/lib/python2.3/site-packages/pilfonts/" At this time, i start to dig in the sourcecode of ImageFont.py, and i found that when it raises the "cannot find glyph data file", is when it try's to open the ".pbm" file with Image.open(), i tried to do this to get more information, and it gives a Error Type: AttributeError Error Value: 'file' object has no attribute 'startswith' I don't know if this makes any sense to you, .... but are there someone to help me in this? Do i have other alternatives to generate images with text on the fly in zope? thanks in advance, --Bruno Silva

setting flags
by John Poltorak 01 Oct '04

01 Oct '04

I've just installed a Zope message board and am trying to get it working but get 'Resource not found' errors when trying to add a msg. I think the security is set up correctly, but the problem may be due to the 'integrated' flag not being set to 1... index_html says:- If you want to integrate MessageBoard in your product you must set 'integrated' flag to 1. How/where do I set it to 1? I realise this will probably be in the Zope docs somewhere but have no idea what I should look for. -- John

python script returning multiple values?
by Laura McCord 30 Sep '04

30 Sep '04

Hi, I have a python script: def userInfo(userName): server = xmlrpclib.Server("http://tweety:8080/RPC2") email = server.da.emailInfo(userName) office = server.da.officeInfo(userName) pwd = server.da.pwdInfo(userName) acct = server.da.acctInfo(userName) dir = server.da.dirInfo(userName) return ..... I need to return all of the values and access them through a zope page template. I can't find any documentation on this situation. I am suspecting I probably need to create a list in my python script but not sure yet how to display the values in my zpt. Any ideas would be greatly appreciated. Thanks, Laura

You can do that with Zope to an even greater extend: it is open source down to the very basics... But nobody provided documentation for all details -- aside from the not too bad source documentation. And I am convinced that this is not bad! You can use documentation extraction tools (like "DocFinder" or "epydoc") to derive most mass documentation. Most of Java documentation you know was derived in the same way. But, as you do not have full source, someone else had to extract it for you. With Zope, you can extract it yourself. > ... >It seems to me >that without a good understanding of the request and session objects and >the available methods and properties of these objects it will be >difficult to write complex applications that are not fragile. I think, I already told you that the most relevant aspects of the request and response objects are documented in the Zope Book. You can write complex applications with the most relevant aspects. You rarely need the more arcane features. In those rare case, you have the source as a last ressort. >Are you a >developer of zope itself or a user of the product? I am a user. Probably one can call me a high end user. But, if necessary, I change Zope, too, or provide additional products and patches as you can see at <http://www.dieter.handshake.de/pyprojects/zope> -- Dieter

How does it see the page before HTML? HTML is a language, not a program. A web browser, among other things, interprets HTML to make what you see on the screen. Web browsers do not (now, at least!) understand TAL, and will ignore any attributes they do not understand. So something must sit between the template and the requesting program to transform the template. Zope (and a few other programs) understands TAL, and will, before handing a page to a requesting client (like a web browser), interpret the TAL and METAL statements, creating an HTML page. --jcc

Newbie namespace question
by Jeffrey Blaze 30 Sep '04

30 Sep '04

Hi all, My question is really about HTML. I am implementing an open source defect tracking system called Roundup (a set of Python modules), and noticed that it uses TAL. However, I looked all through the Roundup and Python HTML and did not find a namespace declaration. Isn't one required? This from (http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/AppendixC.s tx): The prefix identifies the language, and must be introduced by an XML namespace declaration in XML and XHTML documents, like this: xmlns:ns="http://language.creator.com/namespaces/MyAttributeLanguage I realize that the statement above mentions XHTML but not HTML, implying that non-well-formed HTML does not require the declaration. But in the absence of the declaration, how does HTML know how to handle a TAL statement attribute? Why wouldn't it balk as soon as it sees the tal: prefix? Thanks, Jeffrey Blaze

How to trace deadlocks in my application?
by Kirk Strauser 30 Sep '04

30 Sep '04

I'm developing a fairly complex application that involves a lot of SOAP calls to a remote database server and quite a few external methods. All too frequently I'll get a report that the site's not responding, and when I log into the (FreeBSD) webserver I see that the CPU is pegged at 100% with Python eating all available resource. Does Zope offer any functionality that could help me trace which objects are causing these lockups? -- Kirk Strauser The Day Companies

Calendaring product and default view
by Bryan Simmons 30 Sep '04

30 Sep '04

I've recently installed the Calendaring product from the collective. The default view or base_view as the action is known, is an upload page for uploading an iCal file for integration with the calendar. Suppose I wanted to switch this default view to the month_view action instead? I have tried to come up with an easy way of doing it (i.e. some property somewhere including default_page for the folder) but nothing seems to work. The documentation that comes with the product is almost nil, so it wasn't much help. Anyone have any ideas or experience with this? -- Regards, Bryan Simmons -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live. -- Rick Osborne -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
