Reading uploaded file headers
by Greg Green 19 Apr '01

19 Apr '01

I am trying to read the header of a file uploaded in a REQUEST. I can get the filename and the data, but reading the headers gets me an authorization failure. Here is the python script: if file.headers.has_key('content-type'): type = file.headers.get('content-type') else: type = 'text/plain' return [file.filename, type, file.read()] If I remove the first 4 lines, everything works fine. Leave them and I the script doesn't work. Please reply to me off of the list as well, as I am not subscribed. Thanks. -- Greg Green Advanced Design Systems Math & Computing Technology Boeing (425) 865-2790

I have tested it on: Zope 2.3.1 and Zope 2.3.2b1 and the refcounts grows, but on Zope 2.2.4 it seems to work correctly.

Growing Refcounts
by Juan Carlos Coruña 19 Apr '01

Hi, invoking a xmlrpc call on any method, for example calling the default index_html dtml method, causes the delta of xmlrpclib.Unmarshaller and xmlrpclib.FastParser to increase without freeing instantes. After testing with diferent Zope versions I have discovered that calling the same method on Zope 2.2.4 works ok. Can anybody report the same problem? Is there a bug in the latest versions? Any solutions?

Can dtml-in iterate over a list of lists?
by Dunigan, Craig 19 Apr '01

19 Apr '01

I have a Python script called "listArticles" that accepts a sort parameter called "EWSortOrder," and returns a sorted list of lists. I would like to display the list of lists using a DTML method called "ArticleList" that looks something like this: <table> <dtml-in expr="listArticles(EWSortOrder)"> <tr><td class="1">sequence-item[0]</td></tr> <tr><td class="2">sequence-item[1]</td></tr> .... </dtml-in> </table> where sequence-item is obviously the list in the current iteration, but clearly Zope isn't recognizing it as a list: Error Type: KeyError Error Value: sequence-item[0] Traceback (innermost last): File /opt/Zope/ZopeInst/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /opt/Zope/ZopeInst/lib/python/ZPublisher/Publish.py, line 187, in publish File /opt/Zope/ZopeInst/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: CatalogAware) File /opt/Zope/ZopeInst/lib/python/ZPublisher/Publish.py, line 171, in publish File /opt/Zope/ZopeInst/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: ArticleList) File /opt/Zope/ZopeInst/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: ArticleList) File /opt/Zope/ZopeInst/lib/python/OFS/DTMLMethod.py, line 189, in __call__ (Object: ArticleList) File /opt/Zope/ZopeInst/lib/python/DocumentTemplate/DT_String.py, line 538, in __call__ (Object: ArticleList) File /opt/Zope/ZopeInst/lib/python/DocumentTemplate/DT_In.py, line 711, in renderwob (Object: listArticles(EWSortOrder)) File /opt/Zope/ZopeInst/lib/python/DocumentTemplate/DT_Var.py, line 276, in render (Object: sequence-item[0]) KeyError: (see above) Can I do this, and if so, how can I let dtml-in know to expect a list each time? I can't nest dtml-in's because each item in the sub-list is processed a little differently.

ZGETMAIL ? => Zope wget + mail-this-page
by Jason Cunliffe 19 Apr '01

19 Apr '01

Hi A popular feature for some is mail-this-page-to-a-friend. Depending on the circumstances, this ranges from lame harassement to a cool and useful thing. Mostly on the lame side imo, but can offset problem of heavy frames use. Sending a URL is often all that is requirtrd but for dynamic sitses this may or may not produce the intended result. so I am wondering if anyone has already come up against this with Zope, or has good suggestions for doing so. I can imagine a small product, ZGETMAIL, which harnesses a server-side wget tool to snapshot the selected current page in HTML, timestamp it and send or stash it like a digital postcard. Mail-this-Zopepage-to-a-friend would then allow one to send a special url linking to the location holding the snapshot HTML. The goal is to reduce confusion from forwarding URLs whose content changes, and to make it as easy and hassle free as possible to do so [no outlook express instaces screwing things up etc]. Useful especially for people logged into unfamiliar web terminals while away from laptop/home/office. - Jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']

Is there a simple way to define a custom "Unauthorized" message, like a "Standard Unauthorized Message" dtml method? If not, why not?

Almost surely, your problem occurs because you do not call your DTML objects with the two optional but essential positional parameters. Usually call your DTML objects like this: <dtml-var "dtml_object(_.None,_,your_param1=v1,...)"> More info in the DTML section of URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html Dieter

Calling ZClass constructors programmatically...
by sean.upton＠uniontrib.com 19 Apr '01

19 Apr '01

Sorry to bring up this subject, as it seems to be a popular question on the list, but I'm not sure if there is a complete answer to the question in the list archives, HOWTOs, etc. I'm sure I am not alone in trying to find an answer to this... I have been trying a bunch of different things to instantiate a ZClass instance (in this case, it is a custom folder subclassed from ZCatalog:CatalogAware, and OFS:Folder). The ZClass constructor (which works when called by direct traversal from the factory form) is another PythonScript, and I am trying to call the constructor via a PythonScript elsewhere in the ODB hierarchy; my code to do that looks like this: #--------------------------------------------------------------------------- --- container.Control_Panel.Products.Classifieds.AdFolder_add(id=`item.id`, title=item['category'], shortTitle=item['category'], locationDepth=1, redir=0) #--------------------------------------------------------------------------- --- The problem with this is that it creates the instance in the namespace of the product folder where the AdFolder_add constructor resides. I would use container.manage_addProduct['Classifeds'].AdFolder_add() ... but this won't work, because manage_addProduct doesn't understand what 'Classifieds' is (though it does when called through the web and this also works fine programmatically for OFS:Folder...). The code for my constructor is below; I am wondering if there is a way to adjust the script that calls the constructor to have it (somehow) pass the namespace of the calling folder (acquisition parent of the calling script) to the constructor method? Any help anyone might have would be greatly appreciated. If I can find an answer, I will try to piece together a howto... Thanks, Sean ## Script (Python) "AdDayFolder_add" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters=id, title, shortTitle, redir ##title= ## #--------------------------------------------------------------------------- --- #--- Trap for no id, this sucks, and we quit... if not id: return 'Doh! Need an id for object constructor. Try again...' #--- Setup some defaults, in case params passed to this script aren't there... if not title: title="Ads" if not shortTitle: shortTitle='Ads' if not locationDepth: locationDepth='1' if not redir: redir='1' #default is to redirect to instance manager, see comments below #--- Set parameters passed to this script as REQUEST form params... container.REQUEST.set('title', title) container.REQUEST.set('shortTitle', shortTitle) container.REQUEST.set('locationDepth', locationDepth) #--- First, add new instance of an AdFolder class object within the #--- current context / parent folder / aquisition parent container.manage_addProduct['Classifieds'].AdFolder.createInObjectManager(id , container.REQUEST) #--- Secondly, sync the parameters passed to this method with the #--- Property Sheet of the AdFolder instance container[id].propertysheets.Basic.manage_editProperties(container.REQUEST) #--- Now re-index with catalog... container[id].reindex_object() #--- Now, by default, we assume this is a web-request initiated constructor #--- method that is going to need to redirect the browser to some URL, so if #--- redir=1 (default), then this is going to redirect to the management #--- interface URL for the new object instance; there are 2 other options, #--- each with it's own numerical code as possible (used) values of redir: #--- #--- 0 - No Redirect (redirect off) #--- 1 - Redirect default to instance management screen (redirect on) #--- 2 - Redirect to context/parent folder's management screen if (redir == '1'): return container.REQUEST.RESPONSE.redirect(container[id].absolute_url()+'/manage_wo rkspace') if (redir == '2'): return container.REQUEST.RESPONSE.redirect(container.absolute_url()+'/manage_worksp ace') else: return 'OK' #Default return statement, in the case of no redirect #--------------------------------------------------------------------------- --- ========================= Sean Upton Senior Programmer/Analyst SignOnSanDiego.com The San Diego Union-Tribune 619.718.5241 sean.upton(a)uniontrib.com =========================
