Error handling and super users....
by Andy 30 Jun '00

30 Jun '00

Hi, A couple of questions...: a) is there a way of sending an error to a default object other than standard_error_message? For example I would like errors of type x to be handled by one object and y by another. Obviously most objects should have their own error handling that makes sense, but a there are few special cases when I can see it being useful. The most obvious method is to put a big dtml if inside the standard_error_message and send the errors to those objects. But does anyone know of a more elegant solution (if not I can see a potential product in there)... b) anyone know a way of restricting the super_user to a domain? Zope allows you to restrict users, but I would like to tighten down Zope a little more by only allowing super_users from within our domain... Thanks in advance. Andy McKay

Hi, Good, I did it, I mean, I succeeded, I do know how to procceed with LoadSite, Itamar, you should say in your page to download not only wxpython, but also winsock etc.. in the wxpython page, they are saying it, but I didnot see it, 2 other programs, we need to download for see LoadSite working. Ok ? thanks guys ! for your support.. Zope Team should incorporate that software into Zope too. As well as they should put their "Available Object" white box, you know what I mean ? ->ABOVE<- the files. See, when you have 900 files in one directory, you need to scroll down each time.. so I suggest to put that box, you know the box I mean ? Place it at the top of the page.

Has anyone gotten Zope running on either LinuxPPC or OSX? If so, can you share your wisdom on how it was done? We'll also be looking for experienced Zope web site developers so send me your resume if interested. Thanks Jerry Jewell WebDudes, Inc. 916 624 0601

SQL method: Trying to be too clever?
by Andy Gates 30 Jun '00

30 Jun '00

Is it possible to pass a variable into anything other than the values of a SQL method? I'm trying to pass a parameter to a method, such that the param is used to define which field is affected by the action: insert into related (rootstory, <dtml-sqlvar field>) values (<dtml-sqlvar storytitle>, <dtml-sqlvar value>) Possible? This doesn't work, of course... ---------------------- Andy Gates, Learning and Research Technology Andy.Gates(a)bristol.ac.uk - ICQ#74362415

I am trying to set up MySQL user folder [http://www.zope.org/Members/vladap/mysqlUserFolder] on my WinNT box. This product requires the compiled MySQLdb python module. I have MYSQL.pyd, but I'm unable to compile _mysql.pyd on Windows ? Does anyone have this binary ? thanks in advance, Darcy --------------------------------------------------- Ph: (734) 764 3377 Email: darcyc(a)engin.umich.edu URL: http://www-personal.engin.umich.edu/~darcyc/ ---------------------------------------------------

Hello, I need get 2 properties of Zclass at the same time. I´m using in my form : <td><select name="region"> <dtml-in "Locality.objectValues(['Locality']) "> <option value="<dtml-var REGION>"><dtml-var title> </dtml-in> <option selected> </select></td> I need get another property, for example MASTER_REGION, in this moment. How can I to do it? (is urgent!) Thanks in advance, Marcus Mendes

queries and tiny tables and python methods... oh my!
by Timothy Wilson 30 Jun '00

30 Jun '00

Hi everyone, (Please excuse the vague Wizard of Oz reference in the sub., but my brain may be imploding. :-) I'm trying to merge several type of Zope objects, and I'm getting lots of little errors. I wonder if someone could suggest where my problem lies. 1. I'm querying our LDAP server to retrieve the records for a given person in the directory. No problem there. 2. I'm parsing one of the entries in the LDAP directory to retrieve the user's location. Python method code is simple. 3. I'm using a Tiny Table to look up a value for one of the parsed strings. Easy. The problem is hooking them all together. Passing the query to a PythonMethod is throwing up the following error: Error Type: TypeError Error Value: argument l: expected read-only character buffer, instance found (BTW, Netscape on Windows doesn't product a traceback, but Netscape on Linux does.)  parseLocation is a Python Method which takes 1 argument (a string) and returns the first element of the list that's formed by splitting the string. That first element is a two-letter code that's looked up in a Tiny Table called buildingCodes which returns the full name of the building. OK, it looks to my relatively inexperienced eyes that the Python Method isn't getting an argument of the type is expects. Here's the code for parseLocation ('l' is the argument): x = string.split(l, '_') return x[0] (BTW, changing it to x = string.split(`l`, '_') eliminates the error, but nothing is rendered. qry_person is an ZLDAP filter method that takes one argument (uid). The original dtml to display this mess looks like: <dtml-call "REQUEST.set('user_id', user_id)"> <dtml-in "qry_person(uid = user_id)"><br> <dtml-in "buildingCodes(parseLocation(l))"> <dtml-var building><br> # 'building' comes from the Tiny Table </dtml-in> </dtml-in> I'd appreciate it if anyone has any ideas about this. I'm probably making the whole thing too complicated, but for reasons of code reuse, this seemed like the most efficient approach. -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.k12.mn.us/ | http://www.zope.org/ W.

How do you use acquisition when instantiating an object via a REQUEST.set
by Corey Zimmet 30 Jun '00

30 Jun '00

I am a relatively new Zope user and I have a simple python Class in a python product such as: class Item(Acquisition.Implicit): # Just a simple item class def __init__(self, id): self.id=id If I instantiate the object in DTML with somthing like this: <dtml-call "REQUEST.set('item',Item.Item('someid'))"> How can I make the object acquire the current context? I do not want the object to be added to any container other than the REQUEST. Thanks, Corey
