In addition, note that the original number is a unix timestamp - seconds since 01/01/1970. So to add two weeks to it, you'd do: t + ( 2 * 7 * 24 * 60 * 60 ) Anthony >>> "Andreas Jung" wrote > Why do you want to use the timeTime() representation ? > Just add 14 (2*7 days) to the instance of the corresponding > DateTime object. > > newDate = DateTime("2002/02/05") + 14 > > - aj > > ----- Original Message ----- > From: <hpinson(a)indepthl.com> > To: <zope(a)zope.org> > Sent: Tuesday, February 19, 2002 20:12 > Subject: [Zope] timeTime() function question > > > > Can anyone explain the math behind the Python / Zope UTC > > timeTime() function?

timeTime() function question
by hpinson＠indepthl.com 20 Feb '02

20 Feb '02

Can anyone explain the math behind the Python / Zope UTC timeTime() function? I need to add two weeks to a timeTime generated date, for post processing. For example; with the timeTime() generated number: 1014071233.22 What would two weeks from this number be, in timeTime format?

Re: [Zope] CUF, XUF, and the Redmond Axis of Evil
by complaw＠hal-pc.org 20 Feb '02

Some of my users have had trouble when using IE (5.5 or greater, particularly the verion that comes with WinXP). While it doesn't seem to be a server OS issue, I suspect that it does have something to do either with acquisition and Zope (where the acl user folder is located within the heirarchy somehow affecting the cookie) and/or within IE itself (IE somehow making an assumption that anything below the initial login branch is okay but then "invalidating" the assumption when the user goes above the point of initial login). I don't have the code for IE and my search on the 'Net hasn't turned up any evidence to support the latter theory, so take it for what its worth. A conceivable workaround would be to detect an unauthorized person, redirect to the root/home page, authenticate, and then redirect back to the original page. Once IE is authenticated as far up as it can go, it seems to behave itself. How you do the work around, however, is unknown. The workaround that I suggest to my users is to get Netscape. I have that luxury, and that does solve the problem. Unfortunately, that won't help you. Sorry I can't be of more help.

Question about accessing properties of images
by Kevin Carlson 19 Feb '02

19 Feb '02

I have some code where I am in a folder and am accessing an image in that folder by name (passed into the page as an argument named "pic" in the URL). I am trying to access a property ("desc") of the image object ("pic") and am only able to do it using the following code: (Note that I am doing this from the folder containing the image object.) <dtml-in objectItems prefix=p > <dtml-if expr="p_key == pic"> <dtml-var desc html_quote> </dtml-if> </dtml-in> This seems a bit wasteful to go through a <dtml-in> loop in order to retrieve the "desc" property from the image. Is there an easier way to do this?

Using Form data values in ZSQL Method: I must be missing something here
by Howard Hansen 19 Feb '02

19 Feb '02

I'm certain that I'm doing something very silly here, and I've learned many new things about Zope and databases by researching this problem, but I haven't figured out how to make it work. All I want to do is create forms that allow me to insert or update records in a database. Here's the structure I've set up: form: collects the form data, and when the user clicks submit, it calls: action_dtml_method: which calls: zsql_method, which modifies the database and tells the user what just happened When I hit Submit, I can easily list the values from the form inside the action_dtml_method, but zsql_method acts like it has no clue about the form values. It gives me the error: Missing input variable, field_companyname and the traceback:  I've tried using <dtml-call zsql_method>, <dtml-with zsql_method>, <dtml-in zsql_method>, and each of those using "zsql_method()" as well. I could try to pass the values explicitly, but I've used acquisition very effectively in other situations, and I'm not terribly interested in passing 29 parameters to the query. Clearly, I'm missing something fundamental, could someone please tell me what it is? Thanks! Howard Hansen http://howard.editthispage.com

Help: Zope and LDAP
by Tim Hawes 19 Feb '02

19 Feb '02

I am new to this list, new to Zope, and new to Python. I am, however, an old hat to perl, c/c++, and LDAP. I am very interested in Python and would consider picking up the now unmaintained ZopeLDAP package, that is if noone picks it up before me. I have not been able to get the addSubentry() function to work in ZopeLDAP. The docs are not very clear to me in how to use it. >From "PROGRAMMING.txt": 1. Getting an Entry Object and its attributes Using an LDAP Filter object is the best way to get an Entry object. LDAP Filter objects act like methods\functions and return a sequence of entry objects (so they can be used with any sort of looping structure). For example, if you had an LDAP Filter titled 'lookupByEmail' with the parameter 'email' with the content:: mail=<dtml-var name="mail">* Can be used in DTML like this:: [DTML example skipped] Or in a Python Script like this:: entries = container.lookupByEmail(email='jef') for entry in entries: # do something here... This all works fine and dandy for LDAP queries, and I can get selected fields from our LDAP tree in an HTML table quite rapidly with this. The problem comes in the explanation of how addSubentry() works... 3.1. Adding subentries Adding subentries to an Entry object is done through the 'addSubentry' method. Adding subentries is protected by the permission **Create New Entry Objects**. **addSubentry(rdn, [attrs,kw])** -- Add a new subentry identified by the rdn. The rdn **MUST** be a string in the form 'attr=value', such as 'ou=Housewares' or 'cn=Davy Jones'. The rest of the signature can be a combination of a dictionary of attributes passed in to 'attrs' or keyword arguments. If no 'objectClass' attribute is passed in, the default objectClass is 'top'. The newly created Entry object is returned, wrapped in the acquisition context of its parent. Some example uses are:: betty = housewares.addSubentry("cn=Betty Ford", { "objectClass": ["top", "person"], "sn": "Ford", }) clinic = betty.addSubentry("sn=Clinic", objectClass=["top","place"], description="A good place to go..." ) I take this to mean that in order to add subentries, I have to first create an Entry object as specified in the first paragraph that would seclude the object I want to add the object to?! Anyway, I have read and reread this file and it still makes no sense to me. I tried adding an LDAP filter that isolates the organizational unit I want to add entries to (ou=People,<basedn>) specify a basedn with an LDAP filter method called rootOU. I then write this script to work the magic I am hoping for: entries = container.rootOU() People = entries[0] fname = "BBBB" lname = "cccc" name = "%s %s" % (fname, lname) uidname = "%s.%s" % (fname, lname) rdn = "uid=%s" % uidname newentry = People.addSubentry(rdn,{"objectClass":["top","person","organizationalPerson","inetorgperson","dirmuser"], "sn":lname, "cn":name}) print "Success" return printed On test, I get this exception: Error Type: TYPE_OR_VALUE_EXISTS Error Value: {'desc': 'Type or value exists'} Traceback (innermost last): File /usr/local/zope/2.4.3/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/local/zope/2.4.3/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/2.4.3/lib/python/Zope/__init__.py, line 226, in zpublisher_exception_hook (Object: Admin) File /usr/local/zope/2.4.3/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope/2.4.3/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: copy_of_addentry) File /usr/local/zope/2.4.3/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: copy_of_addentry) File /usr/local/zope/2.4.3/lib/python/Shared/DC/Scripts/Bindings.py, line 324, in __call__ (Object: copy_of_addentry) File /usr/local/zope/2.4.3/lib/python/Shared/DC/Scripts/Bindings.py, line 354, in _bindAndExec (Object: copy_of_addentry) File /usr/local/zope/2.4.3/lib/python/Products/PythonScripts/PythonScript.py, line 363, in _exec (Object: copy_of_addentry) (Info: ({'script': <PythonScript instance at f538b8>, 'context': <Folder instance at ff6ad0>, 'container': <Folder instance at ff6ad0>, 'traverse_subpath': []}, (), {}, None)) File Script (Python), line 11, in copy_of_addentry (Object: guarded_getitem) File /usr/local/zope/2.4.3/lib/python/Products/ZLDAPConnection/Entry.py, line 249, in addSubentry (Object: GenericEntry) File /usr/local/zope/2.4.3/lib/python/Products/ZLDAPConnection/ZLDAP.py, line 344, in _addEntry (Object: Hrdhhs34_Directory) TYPE_OR_VALUE_EXISTS: (see above) After pulling hair out of my "already-balding-head" I resolved to by-pass ZopeLDAP altogether and use the python-ldap module directly, much more closely resembles the LDAP C API.

Help in chaining calls to different method types
by roy＠anoobe.com 19 Feb '02

19 Feb '02

Folks, Could someone help me (relative Zope newbie) with understanding how I can chain method calls, with a mixed bag (i.e: py scripts, dtml methods and dtml documents"). I find that the following calling chains fail. DTML_meth -> DTML_meth -> Python_Script DTML_doc -> DTML_meth -> Python_Script For example: x_py: Python script takes 1 parameter (p1) URL works standalone (http://localhost:9673/Test/x_py?p1=23) meth_1: DTML method takes 1 parameter (p1) and passes it to x_py body is: <dtml-var expr="x_py(p1=p1)"> URL works standalone (http://localhost:9673/Test/meth_1?p1=44) meth_2: DTML method takes no parameters body is: <dtml-var expr="meth_1(p1=66)"> URL fails (http://localhost:9673/Test/meth_2) I get the following message: Zope Error Zope has encountered an error while publishing this resource. Error Type: NameError Error Value: global name 'x_py' is not defined doc_1: DTML document. takes no parameters body is: <dtml-var expr="meth_1(p1='ha')"> fails the same as meth_1. URL fails (http://localhost:9673/Test/doc_1) Thanks, Roy Mathew.

Can you be more specific about what you want to do? I wonder if I'm understanding correctly... Why not just use a class variable for all instances of a class implemented for this purpose instead of instance variables? You can do this with both ZClasses and Python products...
