Monkeying with the Zope database
by Steve Jibson 13 Nov '00

13 Nov '00

I've been toying with the Zope database and I'm probably alomst to the point where I know enough to be dangerous. I am trying to make a few changes to the stuff in the Zope database without actually running Zope. Here's what I'm tring to do: 1 - Create a new user in the top level acl_users folder 2 - import a file "login.zexp" into the top level folder (login.zexp has been copied to the import directory) Here's some code I've written: ------------------ import sys sys.path.insert(0, '/home/zope/lib/python') import Zope appRoot = Zope.DB.open().root()['Application'] # create a new user appRoot['acl_users']._doAddUser(name='ThisWebSiteIsMine-SoThere', password='pw', roles=['Manager'], domains=[]) get_transaction().commit() # login as that user owner = appRoot['acl_users'].getUserById('ThisWebSiteIsMine-SoThere') Zope.AccessControl.SecurityManagement.newSecurityManager(None, owner) # import login.zexp and take ownership appRoot.manage_importObject('login.zexp', set_owner=1) get_transaction().commit() ------------------ Here's the resulting traceback: ------------------ Traceback (innermost last): File "go.py", line 22, in ? appRoot.manage_importObject('login.zexp', set_owner=1) File "/home/zope/lib/python/OFS/ObjectManager.py", line 526, in manage_importObject self._setObject(id, ob, set_owner=set_owner) File "/home/zope/lib/python/OFS/ObjectManager.py", line 267, in _setObject object.manage_fixupOwnershipAfterAdd() File "/home/zope/lib/python/AccessControl/Owned.py", line 273, in manage_fixupOwnershipAfterAdd self.changeOwnership(user) File "/home/zope/lib/python/AccessControl/Owned.py", line 166, in changeOwnership new=ownerInfo(user) File "/home/zope/lib/python/AccessControl/Owned.py", line 297, in ownerInfo db=user.aq_inner.aq_parent AttributeError: aq_inner ------------------ It appears to be dying while trying to set the ownership. There's a good chance that I'm going about this all the wrong way (I'm new at this stuff). Any help to fix up what I've tryed or new ways to approach the problem will be appreciated. Thanks, Steve

Re: Advanced search in ZCatalog (Micha)

Hi, I played with ZCatalog and ZClasses a time ago. Due to the fact that ZCatalog can Index all Objects - You Can Index a Method, .....!!! This Methods can be External-, Phython-, or DTML-Methods. But they have to return something to the catalog (DTML-RETURN Tag). You can give this method a name like "PrincipiaSearchSource" or what the hell you think of. In my case I index about 10 different ZClass, 100 Instances of them, with a PythonMethod called text_inhalt (text_contents) Param: self Code return string.join((self.id, self.inhalt), '; ') Or in an subclass return string.join((self.id, self.teaser, self.gericht, self.keys, self.art, self.norm, self.parteien), '; ') Be warned you can use a DTML Method and return something with the dtml-return tag, but this is not working very well within a ZCLass, !!! ?????? P.S.: If you want to call a resultObject (e.g. a ZClass) directly through Zope/DTML/Python use the PyMethod "fetchObj" much cooler than only via catalog.getpath (which is link /hfg/kkjk/) to do somthing like this: <dtml-in mein> ****Result from a canned search <dtml-call "REQUEST.set('meineURL',fetchObj(_,Catalog.getpath(_.int(_['sequence-item']) )))">****convert /parent/child to an real object parent.child <dtml-var meineURL> *** points to a ZClass [Base:Renderable] calling the Object/Class directly, which renders itself </dtml-in> use something like this: Python Method: fetchObj Param: _,fetchStr, attr=None obj = _ for p in string.split(fetchStr, '/'): obj = obj[p] if attr is None: return obj else: return render(_.getattr(obj, attr)) Greetings from Heidelberg Michael Kobald

Usually, I use an external method returning a string containing the text from all the fields I want to search on, and I index THAT field in the Catalog. It works great!

You need to add a user. The superuser cannot own any objects inside zope. Go to the folder called acl_users and add a user with manager permissions. Close all copies of your browser. Open a new one and login as the new user. Then you will be able to add objects.

Zope declining?
by Hung Jung Lu 13 Nov '00

13 Nov '00

Hi, >From the mailing list volume in the last 3 months, it is not hard to see that there is a steady decline. This compared to the trend of last two years (doubling volume every year), should probably raise a red flag. I know what many would say: there are now more experts than newbies as compared to before. There are not as many problems as before, etc. But that is that really all? I don't think so. regards, Hung Jung _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

[ANNOUNCE] New Minimal product How-To
by Max M 13 Nov '00

13 Nov '00

Hi I have just added this Product How-To: http://www.zope.org/Members/maxm/HowTo/minimal_01/index_html I would very much like some feedback as to whether this type of How-To is worth the effort. I wrote it because I would have liked something like this myself when I started. So should I write more like this, or is it a waste of time? Introduction text: 'Zope product programming has gotten a reputation as being difficult. This is not true. I belive that It's simply because the examples that has been shown, like the Boring class, has been too full featured. Furthermore the samples have skipped several steps when explaining the functionality, making "the Zope" way seem long and a bothersome. With all kinds of unnessecary extra code that is added "just because". I remember reading the Boring examples the first time thinking that there was all this deep black magic about Zope that no one really understood, but just did because the had seen it elsewhere. Therefore I have choosen to write a series of How-To's explaining in the simplest possible way how to program Zope. The pace will be VERY slow and every line of code will be explained in detail. If there is ANYTHING that is unclear please tell me about it. (Use the " Feedback to this page's author" link in the bottom of this page.)' Max M. W. Rasmussen, Denmark.
