Newbie ZClass question
by Michael S. Fischer 21 Aug '02

21 Aug '02

Following the example in the Zope Book, I tried creating a new Product containing a ZClass "Quip" using the ZMI (2.5.1). When I add an instance of the Quip product to a folder, the Add form appears. I then enter "test" as the ID and hit the "Add" button. This yields an error message with the following exception and stack dump: Error Type: NameError Error Value: global name 'Quip' is not defined Traceback (innermost last): File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 114, in publish File /usr/lib/zope/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: Quip_factory) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 98, in publish File /usr/lib/zope/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: Quip_add) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: Quip_add) File /usr/lib/zope/lib/python/OFS/DTMLMethod.py, line 127, in __call__ (Object: Quip_add) File /usr/lib/zope/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ (Object: Quip_add) File /usr/lib/zope/lib/python/DocumentTemplate/DT_With.py, line 61, in render (Object: Quip.createInObjectManager(REQUEST['id'], REQUEST)) File /usr/lib/zope/lib/python/DocumentTemplate/DT_Util.py, line 159, in eval (Object: Quip.createInObjectManager(REQUEST['id'], REQUEST)) (Info: REQUEST) File <string>, line 2, in f NameError: (see above) Any idea what's happening here? -- Michael S.

nested login's w/ cookie crumbler
by Dennis Allison 21 Aug '02

21 Aug '02

I am using cookie crumbler with the default acl-users. The site organization (much simplified) looks like root - a - b - one- ... | c - d - two- ... There are separate acl-users folders at root, one, and two The acl-users folder at one and two are disjoint. The root acl-users folder is for admin and managers only. There are two cookie crumblers (default parameterization), each parallel with the acl-users folder in one and two. Each of the cookie crumblers references the default stuff (login_form, logged_in, etc.) The two subsites are supposed to be isolated from each other. This is done by roles. Access to site one requires one of two or three roles, access two requires other roles. Managers get to visit both. At least that's the plan. But there's several things wrong in terms of the observed behavior. I'd appreciate a little help from anyone who understands the interaction of Zope's security and the login mechanism.

That works beutifully, however I ran into another problem... :) I found that "page.xsl" cannot be a zope object, be it a LocalFS['filename'] or a DTML Method or DTML Doc. Is there a way using LocalFS or any other product where I can pass it the actual path rather than the object...??

StructuredDocument PUT_factory problem
by John Hunter 21 Aug '02

21 Aug '02

I have a folder where I want to create StructuredDocuments via ange-ftp using emacs. I wrote a PUT_Factory external method to make StructuredDocument the default for text/plain or text/html PUTs, but I am getting an error when I try the constructor. I have added some extra stuff to see what is getting passed to the put factory, which I'll include below def PUT_factory( self, name, typ, body ): """ Override the default PUT method to make STX page the default type for ftp uploads """ from Products.StructuredDocument import StructuredDocument h = open('/home/jdhunter/tmp/zope.out', 'w') h.write('name = %s, typ= %s, \nbody = %s\n' % (name, typ, body)) if typ == 'text/plain' or typ=='text/html': try: ob = StructuredDocument( body, __name__=name ) except: h.write('Could not create STX') ob = None return ob return None Here is the output file ~/tmp/zope.out. Any idea why my PUT_Factory is failing? name = test3, typ= text/html, body = Structured Text - Introduction Structured text uses indentation and simple symbology to indicate the structure of a document.

Creating python script from python
by Mark Gibson 21 Aug '02

21 Aug '02

I've built a python product that creates a python script in the zodb. This seems to work, the script appears int the zmi where I expect it to, and looks like I expect it to. The problem is, it doesn't work. When I try to use the python script, I get the following error: Error Type: NameError Error Value: global name '_' is not defined I'll spare you the traceback. Suffice to say this occurs in the newly created python script. When I view the bindings on the script, the '_' appears appropriately in the Namespace field. If I now hit 'Save Changes' in the bindings screen, the problem goes away; no complaints about the '_'. Does anyone have any idea why this would happen? Any idea how I can get the script to work without following this procedure? Again, I don't make any changes to the bindings, I simply hit 'Save Changes' button. Thanks, Mark

HOw to use a tal:condition
by zope 21 Aug '02

21 Aug '02

Hi All I wanted to ask about how to use the tal:condition exactly I am trying: <div tal:condition="request.form['txtPL'] == 'john' or nothing" tal:replace="request.form['txtPL']"> List </div> I want to check a condition for a variable :If it is existing or not? But There is some syntax probelm Because I am not being able to check the condition. I am working on XML and I get a fixed error ireespective of what the error is when the value is not available to the request object.The error shown is : The XML page cannot be displayed Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later. End tag 'td' does not match the start tag 'img'. Error processing resource 'http://192.168.10.11:8080/oms/Users/mem'. Line 9, Position 3 Hence I cannot show the error that is actually thrown If the variable "txtPL" doesnt exist it throws an error . But then isnt that suppoosed to be taken care of by assigning the value nothing in the tal:condition. But this does not happen Only if the tal:condition returns true it works(i.e. if there is a value for "txtPL". I f there is no value for "txtPL" it throws an error Could you please tell me what exactly is the syntax for doing a tal:condition check for a variable existing in request. The problem arises in doing the check : request.form['txtPL'] == 'john' Hoiw can i check this value I cant give: request/form/txtPL == 'john' This also thorws an error.

python ques
by AM 21 Aug '02

21 Aug '02

Hi all, I realize the following is a python question but my post on comp.lang.python has been languishing there for some time now without any replies, so I just wanted to check if any of you knew a way out of my problem... I am trying to convert XML docs to HTML docs using an XSL file on the fly. The function (external method ) that I have which does it is the following: ## code begin import libxml2 import libxslt styledoc = libxml2.parseFile("page.xsl") style = libxslt.parseStylesheetDoc(styledoc) doc = libxml2.parseFile("xml_file.xml") result = style.applyStylesheet(doc, None) #--- style.saveResultToFilename("-", result, 0) #--- style.freeStylesheet() doc.freeDoc() result.freeDoc() ## code end Now the only problem with this is that result which is an xmldoc object can only save to a file, I looked at the source of libxml.py:xmldoc. It can dump and save in a variety of ways but only to a file or if the arg is "-", as above, to the standard output. I wanted to save the contents of result to a string which I could then send back as part of the RESPONSE object. So I have two ques: 1. If possible, how do I save the contents directly to a string so as to bypass the whole "print open(html_file).read()" thing?? OR 2. How do I trap the output being sent to stdout and capture it into a string??

LOGIN MECHANISM
by chpeer2002 21 Aug '02

21 Aug '02

What I want to realise: - web-application with zope user login - username, password stored in an Interbase database - session tracking I've been searching for a while how to solve the login problem. Could you give me an answer to the following questions? 1) Is it possible to use the normal acl_user folder together the Interbase database? (How??) 2) Situation with ZODB: given is a web-page where a user can decide on one of two web-apps. He than has to login (zope user) using a web form. When the user logs out and than clicks the "back" button of the browser a few times he comes back to the first page. When the user now decides on the other web-app he is automatically logged in because the username and password are the same for both apps. I would like to force the user to login again. Do you have an idea? 3) Which login mechanism is used at zope.org? (ZODB??) Thanks for any help? Christian
