[ANSWER] 500 error with IE on login
by Gregory Dudek 07 May '02

07 May '02

This presents a longwindeded solution to a problem I posted here. I think I may not be unique in having this problem. Problem: A while back I posted a question here regarding a problem I was having with login screens. Specifically, users using MSIE on Windows were getting a "Server Error" page saying "The page cannot be displayed" (error 500) instead of my login page. The login folder product I was using was the Generic User folder product (GUF) but I am almost certain the problem afflicts other user folder products like Extensible User Folder. I am running zope 2.4 It turns out the problem is unique to MSIE (Internet Explorer) on the windows platform. As far as I know it does not occur with any other browser including mozilla, netscape (even on Windows) or even the Mac version of MSIE (Thanks due to complaw(a)hal-pc.org from this list in helping run tests). It seems to happen with version 5.5 and version 6.0 of MSIE but not on every machine -- differences might be a subversion/patch issue. Explanation (mainly due to Oliver Bleutgen via this list): the 500 error is generated by zope and appears in the page header. It's part of the mechanism for catching an access violation that leads to a request for login. The problem is that when MSIE sees this error it does not display the rest the login page that follows, but substitutes it's own internally generated page instead. Solutions / Work-around: There are 2 solutions, one based on users changing their preferences the second a code-hack to zope itself. First the easy but sub-optimal work-around: If the user turns off "friendly" error messages in their browser the intercept by internally generated pages can be avoided. Of course, forcing the user to do this is ugly. For a page I made giving detailed user-level instructions, see the following: http://abatonix.dyn.dhs.org/mudcritters/windowsLoginProblem A once-only pointer to this message is generated by the following DTML on my home page ( http://www.mudcritters.com ): <dtml-if "(AUTHENTICATED_USER.getUserName()=='Anonymous User')"> <dtml-if "(_.string.find(REQUEST.get('HTTP_USER_AGENT'),'Windows')>=0) and (_.string.find(REQUEST.get('HTTP_USER_AGENT'),'MSIE')>=0)"> <center> <dtml-if "REQUEST.has_key('MSIEwarning')"> <dtml-else> (Once-only obnoxious mega-sized message.) <dtml-call "RESPONSE.setCookie('MSIEwarning', AUTHENTICATED_USER, expires=(ZopeTime() + 365).rfc822(),path='/' )"> </dtml-if> WARNING: As a user of Internet Explorer on Windows, to login properly <a href="windowsLoginProblem"> click here. </a> </center> </dtml-if><dtml-else></dtml-if> Alternate solution: I modified zope not to give a 500 error as a default in such cases. Then things work fine with all browsers and nobody has to muck with any preferences. I actually think the 500 error in inappropriate in this case so I removed it. The code hack may have other side-effects although since most browsers ignore the 500 error I think it should be OK and it runs fine for me. In line 240 of lib/python/HTTPResponse.py (in the zope directory) change the lines: if type(status) is types.StringType: status=lower(status) if status_codes.has_key(status): status=status_codes[status] else: status = 500 self.status=status to read: if type(status) is types.StringType: status=lower(status) if status_codes.has_key(status): status=status_codes[status] else: status = 200 # GD changed above from 500 as a hack self.status=status Sorry this is so long, but I wanted to save the next poor soul who gets bitten by this.

Upload Photo objects in a localFS

I have a local file system named images. I would like to write-in photo objects. When I write an Image object with <dtml-with images> <dtml-call "manage_addProduct['OFSP'].manage_addImage(REQUEST['id_img'],file,'')"> </dtml-with> there is no problem, but when I try to write a Photo object with <dtml-with images> <dtml-call expr="manage_addProduct['Photo'].manage_addPhoto(id_img, '', file)"> </dtml-with> Zope generate the next error : Error Type: Bad Request Error Value: Cannot add objects of type 'Photo' to local directories.

Thanks in advance for the help or the ideas you can give to me. William.

How do I get an attribute from object, without aquisition
by Max M 07 May '02

07 May '02

I am trying to get at an attribute from an object. First I check if it exists via "hasattr(obj, id)" but the problem is that there are other objects with the id further up in the aquisition chain. So I get some objects that I don't want. How do i limit my hasattr() to just an object and not the aquisitioned attributes ?? regards Max M

Zope Questions
by George M. Ellenburg 07 May '02

07 May '02

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Greets. I'm (slowly) learning Zope, and loving every bit of it, but have run into a few snags. I'm quite comfortable with PHP, which I know is the source of a lot of my problems as Zope and PHP are two entirely different paradigms. There's just so much information on the Zope website, that I'm having a difficult time finding the answers to certain problems, which unfortunately have left me in somewhat of a quagmire. Can someone point me to the location where I might find more information on the following, with regards to Zope: - Variable Passing through GET request Here's what I'm trying to do: I'm trying to create a "tool-tip" (which is actually contained in a frame) and would like to pass a parameter to the DTML document which contains the HTML, etc. for the tool-tip. Something like: <a href="show_tip?a=b&c=d"> Q: Is there a magical Zope variable that contains the arguments passed on a GET URI (as in PHP?) Q: Must any variable be declared first? - "case" statement Q: Does there exist the equivalent of a shell "case" statement in Zope? (This is in line with my previous questions). Thanks in advance.
