Well, that sounds like a bug. I'd stick it in the collector, although I can't say I've seen that behaviour myself. Are you usign any weird userfolders? cheers, Chris

AW: [Zope] search & edit

I don't know if it is what you want, but if you want to have just some code for BASIC input/edit/delete you can install the product Znolk (version: 0.1.3d). It generates the necessary forms and sql-methods. You will find the latest version on www.bluedynamics.com --> products --> Znolk. > I'm about to start building Zope w/PostreSQL search and edit > forms.

You can put it into a product (HowTo on zope.org) or use it in an external method. In both cases, you would need to learn something about Zope security. There is a documentation of Brian about this topic on zope.org. Dieter

load_site.py doesn't recognize .jpeg
by Paul Winkler 22 Feb '01

22 Feb '01

Hi, Possibly this has been noted and fixed already, but just in case... In Zope 2.2.2, the utilities/load_site.py script doesn't recognize the .jpeg extension - it treats them as plain text files. I solved this by adding one line as shown below. def upload_file(object, f): if os.path.isdir(f): return upload_dir(object, f) dir, name = os.path.split(f) root, ext = os.path.splitext(name) if ext in ('file', 'dir'): ext='' else: ext=string.lower(ext) if ext and ext[0] in '.': ext=ext[1:] if ext == 'jpeg': ext = 'jpg' ### THIS IS THE NEW LINE if ext and globals().has_key('upload_'+ext): if verbose: print 'upload_'+ext, f return globals()['upload_'+ext](object, f) if verbose: print 'upload_file', f, ext call(object.manage_addFile, id=name, file=open(f,'rb')) -- ................. paul winkler .................. slinkP arts: music, sound, illustration, design, etc. web page: http://www.slinkp.com A member of ARMS: http://www.reacharms.com

How to write a ZClass constructor method in PythonScript?
by Dirksen 22 Feb '01

22 Feb '01

Inside a ZClass A (extended from objectManager), I define another ZClass B, here is what's in the default contstructor dtml method for B: <dtml-with "B.createInObjectManager(REQUEST['id'], REQUEST)"> ... </dtml-with> Well, I rewrite it in PythonScript, and modify the factory and add_form to point to this new method. The script is like: req = context.REQUEST container.B.createInObjectManager(req['id'], req) I think the PythonScript verion is equivalent to the DTML verion. But in the experiment, the PythonScript complains that B is not a attribute of the container, i.e. an instance of ZClass A, while the DTML works fine. Why is the ZClass definition not exposed to PythonScript? Any hints please! Cheers Dirksen __________________________________________________ Do You Yahoo!? Yahoo!

quick question - database connections in python methods & return types?
by Lee 22 Feb '01

22 Feb '01

Hi there, I have a quick question that I need answered concerning the return types of SQL queries executed in Python methods. I am querying/updating a database using Python methods as follows: -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ # make a database connection string try: db_conn = self.MySQL_database_connection() except Exception: return "A connection to the database could not be made. <a href='./'> Recover</a>." try: SQL = "some SELECT query" result=db_conn.query(SQL) except Exception: return "The class could not be created.<a href='./'> Recover</a>." -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ When this is executed and I "return result[1]" it outputs the data in a format like: [(1, 16, 9, 1)] * return result[0] gives me: [{'name': 'PRACTICALS', 'type': 's', 'null': None, 'width': None}, {'name': 'TUTORIALS', 'type': 's', 'null': None, 'width': None}, {'name': 'ASSIGNMENTS', 'type': 's', 'null': None, 'width': None}, {'name': 'BONUS', 'type': 's', 'null': None, 'width': None}] - the exact details aren't neccessary here I think. At first I had problems trying to use this data i.e. parse it an store it in an array, list, etc. but I overcome that by by first converting "result" to a string using `result[1]`. I was just wondering how to classify the original return type? It is *not* a list, tuple, array or combination of either so what is it? I'm writing a report on my project you see and I can't say that my method returns an *cough* *cough* value ;-) Thanks very much in advance if you can help. Cheers, Lee

Virtual Host Monster problems
by John Morton 22 Feb '01

22 Feb '01

I'm having some difficulties getting the virtual host monster object doing what it ought to be doing. My set up is Apache doing proxy pass thing to the magic virtual host monster path names on a Zope 2.2.5 install that's using Site Access 2.0.0b4. What it's suceeding in doing is serving pages from the name virtual URLs; what it's not doing is translating internal page links at all. The wierd thing is that I got the whole thing working without a hitch on a very similar install at home, yesterday. The only differences of note are that this instance of Zope has a few more products installed (can't tell you which at this stage) and that the home install was a fresh name virtual setup, where as the problem one started out as a SiteRoot name virtual setup and is being converted to use the Virtual Host Monster method. So, has anyone encountered this problem before? Does anyone have any idea where I should start trying to fix this problem? John
