Re: [Zope] name conflict - ImageFile

Sure. You just need to 'packagize' PIL. Place the PIL directory somewhere in your Zope's python's path. Add an __init__.py to the PIL directory. Inside the __init__.py place the following: # Add any additional PIL modules that you want imported. # This is one, long import statement that my email clien will # wrap. import Image, ImageFile, ImageEnhance, ImageDraw, _imaging, GifImagePlugin, JpegImagePlugin, PngImagePlugin, BmpImagePlugin HTH Drew > Lauri Posti <lauri(a)mutabor.ee> said: > I ran into trouble when trying use PIL (python imaging lib) in zope > product. > The problem is that zope's App.ImageFile is used by PIL's internals > instead of PILs ImageFile and of course this doesn't work. > > Any ideas how to fix this problem? > > Im using Debian Linux 2.2 pyhton packages. > > > thanks, > Lauri

You have to set that checkbox in the account, that is supposed to access that data in it's default view, or in that account session you must use the "Go-control" to switch to the shared account.

The right solution is of course: def recursiveMethod(self, obj, result): if hasattr(obj, aq_parent): result.append(obj.title) recursiveMethod(self, obj.aq_parent, result) return result which you will have to call like this (assuming you external method in Zope is called recursiveMethod): <dtml-var "recursiveMethod(<obj>, [])"> Working with a keyword argument didn't work for me.

ZSQL arguments
by Stephen Harrison 30 Mar '00

30 Mar '00

Hi, ZSQL methods can have two types of string argument, string and required, where required is a non-empty string and a string is (one assumes) a potentially empty string. Although does not say in the ZSQL users guide, it would be nice if strings were also not required to exist as arguments, which to my mind is the logical progression of allowing an empty string. The reason I want to do this is that I am writing sql methods which build queries based on the existence of certain arguments. Obviously I can code the logic to test for empty strings, but it would be neater and simpler to be able to simply have <dtml-if myarg> ... The other reason this would be a neater solution is that it would avoid the need to set up lots of empty arguments in the dtml which calls the sql method. Comments?

dtml-return'ing the result of a SQL select (does not work)
by Dr. Peer Griebel 30 Mar '00

30 Mar '00

Hi, I just tried to implement something as described in the How-To How To: Use GenericUserFolder with an SQL database It does not work. The problem boils down to the fact that I can't dtml-return the result of a SQL query. I wrote the Z SQL Method 'qryTest': select * from mytable This method can be executed without problems. It displays all rows in the table. And I wrote a DTML Method 'returnData': <dtml-return qryTest> When calling the method I get Resource not found Traceback (innermost last): File D:\Programme\uZope\lib\python\ZPublisher\Publish.py, line 214, in publish_module File D:\Programme\uZope\lib\python\ZPublisher\Publish.py, line 179, in publish File D:\Programme\uZope\lib\python\Zope\__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File D:\Programme\uZope\lib\python\ZPublisher\Publish.py, line 167, in publish File D:\Programme\uZope\lib\python\ZPublisher\HTTPResponse.py, line 299, in setBody File D:\Programme\uZope\lib\python\ZPublisher\HTTPResponse.py, line 511, in notFoundError NotFound: (see above) I'm using Zope 2.1.4, WinNT.

(no subject)
by Bruno FAURE 30 Mar '00

30 Mar '00

Hello, I've just discovered Zope, and would like to get more information about it as it seems quite interesting . But I'm not sure I could use it for the web project I'm working on. First, I'd need to stock XML files in an object database like the one provided with Zope. What kind of requesting language may I use ? XQL ? Xpath ? XML-QC ? OQL ? XOQL ? Second question, is there a java API integrated in Zope ? If not, is it possible to interface Zope with others java products as Resine, servlet engines, EJB server...? Thanks in advance Bruno Faure

Zope and memory usage
by Tony McDonald 30 Mar '00

30 Mar '00

Hi, I just ./stop and ./start'ed two Zope servers that were taking up rather a lot of memory; PID USERNAME THR PRI NICE SIZE RES STATE TIME CPU COMMAND 841 nnle 12 33 0 395M 318M sleep 177:24 0.00% python 834 nnle 9 23 0 531M 14M sleep 101:20 0.00% python Is there any way of telling what objects are taking up this memory - could it be a memory leak in Zope at all? I'm using src-2.1.3 on Solaris because I still use the /REQUEST hint to see what my variables are. cheers, Tone. ------ Dr Tony McDonald, FMCC, Networked Learning Environments Project http://nle.ncl.ac.uk/ The Medical School, Newcastle University Tel: +44 191 222 5888 Fingerprint: 3450 876D FA41 B926 D3DD F8C3 F2D0 C3B9 8B38 18A2

variable SQL insert method
by Allen Wallis 30 Mar '00

30 Mar '00

Hi, I have a database with 3 tables. I would like to create a ZSQL method for inserting data into the tables. I started by creating a separate method for each table, but that seems a bit of a waste. Ideally I would like to have one method, "addEntry". The template would look something like: <dtml-if "tname=='supplier'"> INSERT INTO <dtml-var tname> VALUES (NULL, <dtml-sqlvar sup_name type=string> etc...); <dtml-elif "tname='manufacturer'"> INSERT INTO <dtml-var tname> VALUES (NULL, <dtml-sqlvar man_name type=string> etc...); </dtml-if> The problem is that I have to specify the arguments in the argument list, and the arguments are different for each if clause in the above code. Is there a way around this? thanks Allen

problem with dtml-if
by Anders Holmbech Nielsen 30 Mar '00

30 Mar '00

hi, I have this code in a dtml method called "test": <HTML><body bgcolor=#ffffff> <form action="test" method="get"> <SELECT NAME="day"> <dtml-in "(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26 ,27,28,29,30,31)"> <OPTION VALUE="<dtml-var sequence-item>"<dtml-if "_['sequence-item'] == day"> SELECTED</dtml-if>> <dtml-var sequence-item> </OPTION> </dtml-in> </SELECT> <input type="SUBMIT" name="SUBMIT" value="go"> </FORM> </BODY></HTML> It should "remember" the day selected and choose that as the default when making the select box. But for some reason the sentence: <dtml-if "_['sequence-item'] == day"> SELECTED</dtml-if> Doesn't work. I have also tried ... == _[day] ... == 'day' ...and a lot of other stuff but with no positive result.
