using ZODB/Catalog outside of Zope - What am I doing wrong?
by Roman Milner 11 May '00

11 May '00

Hello. I'm trying to use the ZODB and Catalog out side of zope. I have three fields in my class: two FieldIndex and one TextIndex. Searching on the FieldIndexes works fine but searching on the TextIndex returns strange results. Sometimes I get nothing on something that should hit and other times the wrong result for things that do hit. The two scripts are below. If you try running the search script and pass it "Second" you will see what I mean. It will return "First Test" instead of "Second Test". Thanks for any help, ^Roman #############crawler.py############################# #! /usr/bin/env python import sys sys.path.append('/usr/local/Zope/lib/python') import ZODB import Persistence from Persistence import Persistent from ZODB.FileStorage import FileStorage from Products.ZCatalog.Catalog import Catalog class CURL(Persistent): def __init__(self, url, ctype, the_data): self.url = url self.ctype = ctype self.the_data = the_data def identify(self): print "URL: " + self.url + " Text: " + self.the_data class URLStorer: def __init__(self, file='./db/db.fs'): self.file = file self.db = ZODB.DB(FileStorage(file)) self.co = self.db.open() self.root = self.co.root() if self.root.has_key('cat'): self.cat = self.root['cat'] else: self.cat = Catalog() self.cat.aq_parent= self.root self.root['cat']= self.cat self.cat.addIndex('url','FieldIndex') self.cat.addIndex('ctype' ,'FieldIndex') self.cat.addIndex('the_data','TextIndex') get_transaction().commit() def storeURL(self, curl): uid = id(curl) print "stored as " + str(uid) self.root[uid] = curl self.cat.catalogObject(curl, uid) get_transaction().commit() def searchURL(self, **kw): r = self.cat.searchResults(kw) k = [] for i in r: id = i.data_record_id_ k.append(root[paths[id]]) return k if __name__ == "__main__": a = URLStorer() a.storeURL(CURL('http://foo', 'text/html', 'First Test')) a.storeURL(CURL('http://safbar', 'text/sdfhtml', 'Second Test')) a.storeURL(CURL('http://asfasf', 'afasfs', 'Third test')) a.storeURL(CURL('http://asfasf', 'afasfs', 'Fourth test')) ########################search.py################# #! /usr/bin/env python from crawler import CURL, URLStorer import sys b = URLStorer() ids = b.searchURL(the_data=sys.argv[1]) for i in ids: i.identify()

Because there is a resource impact on doing this sort of thing, it wouldn't happen all at once so I'd like the Wiki to work toward general agreement on goals and priorities.

Not that big, I think; I've only come to zope this week after formerly using bobo a few years ago, i.e. a couple of the modules that make up zope. As such I can't speak for the ZODB or all the other fancy-shmancy stuff that's new since then, but I've built a template processing system using DocumentTemplate and modifying it slightly (new tags, new syntax). In the process I got irritated many times, and I've been wanting to complain for a few days. This is close enough to the time. ;) COMPLAINTS AGAINST DOCUMENT TEMPLATE - crappy way of registering new tags. - mapping dictionary is too screwy. - can't pass arbitrary values/objects - _pop and _push don't work as expected, can get invalid and choke. - should have the rest of the standard dict stuff setattr, keys, etc. - pDocumentTemplate and cDocumentTemplate have different bugs :( - Should have a way of backtracking (delayed render?) - Zope-specific stuff (manage_blah) is part of the base package OK, those are just my irritated notes, cut and pasted from a sticky. There's other stuff, which people have noted on the site in writing new tags. Rather than complaining about it, however, I wrote a couple of base classes: generic_re_class (for new tag syntaxes), GenericTag.Block and GenericTag.Inline. They deal with some of the DT weirdness (like tag arguments) and made things *so* much easier... So let's get a Wiki going where I can do my first bit of giving back to the community! And, I want to use ZSQLMethods, although I haven't looked at how separateable they are...

Folks, it's about time (or past time) Zope is splitted from its monolithical package into the real packages it uses. I'm facing similar problems when using ZPublisher.Client in gnope. These things should IMHO be distributed as independent Python packages, at least: - ZODB - Catalog - ZPublisher - StructuredText They were all designed to be Zope-independent (ok, the only good reason to use ZPublisher outside Zope is for clients, but anyway, it's designed to make other things possible). I'm sure there are more. What would be the drawbacks of making these subpackages independent? Management? I don't think that would be too bad. And the possibility of having them released independently is also a very big bonus (StructuredText is _so_ unmaintained that there are people working on an independent version - and it looks cool!)

Creating a new product, adding methods
by Thomas Weholt 11 May '00

11 May '00

Hi, I`ve made a product based on 'Boring Product' and would like to use my own python-objects and methods. I got objects and methods in a seperate file, let`s call it 'my_stuff.py'. ( very impressive, I know :-> ) How can I use my methods in dtml-docs without using them as external methods? I do have a working product, so I guess I could import them or init. them there, but how? Say my module has a function 'testMe' that takes a couple of arguments and returns a string. How can I call this method from dtml?? Is there are doc on this subject, creating a product, adding features etc. where most of the stuff are done in old-fashioned python-code? I want to add stuff like methods, objects and functions using Python, not the Zope-interface. And, finally, is it normal procedure to return the results from methods and functions as formatted html, or should the formatting be done in the dtml-document itself?? Thanks. Thomas

Development note
by Michel Pelletier 11 May '00

11 May '00

Zope 2.2 has a new security API. Amid all the trojan news, I wanted to remind developers of Zope products that this new API should be used in many cases where users traditionally queried AUTHENTICATED_USER for something. If, in your code, you get information from the AUTHENTICATED_USER object then you should take a good look at the new API. Unless developers switch to this API, their products are potentially less secure than code that does use this API. All the details are in the Wiki... http://www.zope.org/Members/michel/Projects/Interfaces/SecurityPolicies -- -Michel Pelletier http://www.zope.org/Members/michel/MyWiki Visit WikiCentral for the latest Zen: http://www.zope.org/Members/WikiCentral

Hi, I have a question, is there a way or is there a product, to create a folder in the managementscreen of zope which mapps to the normal filesystem on the server. This is very useful because sometimes i have to call cgi-scripts from zope. But i can't see in zope what scripts are in the /cgi-bin/ folder. Has anyone an idea. mfg as
