[Zope-dev] Folderish objects and multiple inheritance
Hi there,
Ok so I have a class that has multiple inheritance. My main class (A) works
fine, but I wanted to add in folderish properties. The problem is the order
of multiple inheritance and viewing folder objects. When you view a folder
from you call index_html and this gives a content list.
By inheriting this way:
class B(A, Folder):
I have kept all my A methods. However viewing it does not produce the
content list since its overwritten by A. Of course inheriting:
class B(Folder, A):
Does work for that, but breaks all my other methods.
Solutions:
Well I tried defining a tab - view_folder which was something along the line
of:
def view_folder(self, client=None, REQUEST={}):
''' doc string '''
return Folder(self, client, REQUEST)
But get an attribute error on manage_tabs.
Any ideas?
Thanks.

Re: [Zope-dev] Folderish objects and multiple inheritance
Well if anybody is interested I did solve this but instead of trying to
inherit A, Folder and then fix the folderish methods broken I did Folder, A
and then overrode class A methods I wanted.

[Zope-dev] Custom dtml tag
Im playing with a custom dtml-tag along the lines of constructs a url to a catalog query. It works fine, I would just like to extend it a bit and for this I would need to get to the calling object. For example, there will be a different query depending upon the object the dtml-query tag is contained in. Does this make sense, does anyone know the answer?

I can see how this would be useful in a situation where I dont have an instance of self. But in this case I do, so Im not sure how this helps.

Re: [Zope-dev] Custom dtml tag
Really? Ive looked up this and get nothing (an attribute error actually) and
its not in globals. If that would work that would be great - but a it
certainly doesnt seem to on a standard DTMLDocument / Method.

[Zope-dev] Advice on DTMLDocument
Hi there, Well a while ago I came across a bug that I couldnt cut and paste and object. A few people helped me out on that, thanks. Ive had a week of squishing bugs and finally got to this one. The reason why? I was subclassing DTMLDocument but using my own __init__ (similar to one where I dont subclass from DTMLDocument), where I didnt fiddle with __name__. The result was when absolute_url() was called I was getting: http://fork:8080/code/test/ElementWithAttributes ! Solutions I have found for this: -Dont subclass from DTMLDocument. This is not an option for me. -Dont try to use your own __init__, use DTMLDocument. This works great, but now I have to recreate all my objects. My current scheme is create the object in manage_addObject, let DTMLDocument do the __init__, then manipulate it then and there in the manage_addObject. Help would be appreciated on: -Why is this happening? A class fine breaks if you subclass DTMLDocument, it would seem __name__ is being used some times, not in others. -Is something funky happening in DTMLDocument __init__, which subclasses DTMLMethod etc...? Ive got a fix, but I only sort of know why and that bugs me. Thanks. -- Andy McKay, Developer.

[Zope-dev] Zope Error message
So now I need to change it so most normal errors (such as 404) are handled by standard_error_message. So I went to HTTPResponse.py and found this: def _error_html(self,title,body): # XXX could this try to use standard_error_message somehow? I gather someone smarter than me has tried this before.

Is there an method that I can use as a hook when an object is destroyed? (Im trying to save some _v_ data prior to destruction. Ive tried __del__ but this doesnt seem to get called.

Re: [Zope-dev] Custom dtml tag
Finally woke up on this problem.
Got this working by simply calling resolve_url upon the request object. But
what I want is a result that changes depending upon the object. Let's face
it, this can be acheived a whole lot easier by creating a method for the
objects and calling that.
So thats what Ive done and stayed away from using a dtml-tag.
Thanks for your help.

Re: [Zope-dev] __del__
I was hoping to have this method fired Zope is shut down, restarted etc and not call it implicitly. The theory being if this object is cached it will have to be unloaded at some point?

[Zope-dev] Do I really understanding caching?
We have been looking at caching in Zope as a way of tweaking performance. Heres an example of what I think happens: - Supposing I have a 1,000 object catalog. If one person changes an catalog aware object, that instance of the catalog will be pulled out of the ZODB and changed. It will then be written to the ZODB. That last copy will stay in the cache for as long as the "Cache Parameters" are set to allow. - If somebody changes another catalog aware object, that will repeat the above process. - However simply accessing the catalog (no changes) will pull the object from the cache. - What would be really nice is if the object only got written to the cache when it is no longer used, that way every time the catalog changed it didnt write to ZODB instead it changed the cached version. Of course that does bring up the recovering from disaster problem. So do I understand it correctly? -- Andy McKay, Developer.

[Zope-dev] why cant i rename an object from an external method
Heres a treat. I'm trying to write an external method to rename objects. I have approx 10,000 to rename so a script would be nice. No problem I thought, imitate a forms manage_renameObject and CopySupport.py can do the work. Rename works fine from the web form, but not from a script. (ASPNTools.getsomeobjectsfromstring returns a bunch of objects, Ive tried replicating this with resolve_url and get different namespace error, could this be a clue?). Heres my script: def search(self, REQUEST=None): l = ASPNTools.getsomeobjectsfromstring(self, REQUEST['path'], REQUEST) for obj in l: ob = obj.aq_parent # get the folder ob.manage_renameObject(obj.id(), 'Foo') return 'renamed' Here's my problem: The object 100BASEFX does not support this operation File d:\p4\Zope-dev\lib\python\Products\ASPN/Extensions/foo_rename.py, line 6, in search (Object: 100BASEFX) File d:\p4\Zope-dev\lib\python\OFS\CopySupport.py, line 288, in manage_renameObject (Object: Traversable) File d:\p4\Zope-dev\lib\python\OFS\CopySupport.py, line 406, in _verifyObjectPaste (Object: Traversable) Copy Error: (see above) There surely must be simple way of doing this so I dont have to resort to writing a Perl script to imitate the browser, please!

[Zope-dev] _setObject error - urgent!
Hi, I think I have traced my error with cut and paste, I am getting an error on _setObject. If the object is not registered with Zope properly this will be a problem. Basic synopsis: Im importing an object from a script so Im getting a handle to the folder I would like the object to be in: this is obj. Then I call add and set object: obj._setObject(id, globals()[doctype](id, m)) This rather unusual syntax allows me to use a constructor for man different objects. The type is specified in 'doctype', I then get this error: 2000-08-31T16:56:57 PROBLEM(100) ASPNDoc Error: [exceptions.NameError: cat] Any ideas?

Re: [Zope-dev] Fw: 2gb file size
Ive tried truncating the file and then running fsrecover.py, but get: File "ZODB\FileStorage.py", line 1530, in read_index if read(4) != packed_version: raise FileStorageFormatError, name FileStorage.FileStorageFormatError: q:\var\Data.fs As a desperation I commented out line 1530 and reran. It runs through the entire file and reduces the data.fs to 1k. Am I totally hooped?

[Zope-dev] Cache parameters
Just wondering what kind of cache parameters people run on their Zope installation. It would seem running a high target size and maximum time between accesses would speed up those requests it can find the cache, but not cached request take longer since more RAM is used in the maintaining of the cache (guess). Has anyone found a sweet spot away from the standard, I guess of course it all depends on the individual Zope site, this one is particulary ZCatalog heavy. Or should I just leave it at the default, which I found seems to work fine. -- Andy McKay, Developer.

[Zope-dev] Re: [Zope] IIS and PCGI
Well I fixed this using a ISAPI filter which I will release soon (once I have some time) that takes a url /a/b/c/x.pcgi/f/g/h, and passes /a/b/c/x.pcgi to IIS so the file will run and /f/g/h to Zope. My next question is has anyone succeeded in getting this to work to another box over a mapped or shared win32 drive? I mapped g:\ to my zope host, and then specified PCGI_PUBLISHER=g:\pcgi\pcgi_publisher.py in my pcgi file. The problem seems to pcgi-wrapper.exe which does not like a mapped drive.

[Zope-dev] calling SQL from External Method and using acquisition
This is just an annoying namespace issue: - I'm calling SQL methods from External Methods by . - I can then call a SQL method by calling self.sql_method() But (there is always a but): - I have to manually pass all the arguments, very annoying. Work arounds that seem to work - manually pass all the arugments, great except its my code rigid, Id like to use acquistion - call a "wrapper" DTML Method, which calls the ZSQL method, I still have to pass manually but then get to use acquistion to pick up other stuff. Very cool. But now I hace one wrapper class for every SQL method. Is there a simpler way I have missed? -- Andy McKay, Developer.

Re: [Zope-dev] case insensitive sorts
My main point is that the user who visits my site does not care about python, Unix, NT or any wierd metaphors about kettles. They want information fast and most users expect case insensitive sorts.

Except for the fact that Zope also checks that the first character is not a
_. Thats a big security headache. To be honest Im not so worried about Zope
being more restrictive.
> * Zope allows space characters in (ObjectManager) id's.

This one is much more important in my mind. Its a real pain. Is there a good
reason for this. It should be easy to fix, actually looking at the regex in
Object Manager, shouldn't that just be a case of taking the space out of the
end of the regex?
ObjectManager.py
line 112: bad_id=ts_regex.compile('[^a-zA-Z0-9-_~\,\.]').search]
On a more anal note could we also patch ObjectManager to tell the user what
characters aren't allowed eg:
line 224: 'The id "%s" contains characters illegal in URLs.' % id
should be
line 224: 'The id "%s" contains characters illegal in URLs. Only characters,
digits and the characters ~-_,. are allowed.' % id

[Zope-dev] Old to new registerClass
Im hacking around IEMethod and it uses an old style of class initialisation
in the __init__.py along the lines of:
misc_ = { 'imagef':'foo','imageg':'goo', }
lang_= { 'en':'lang_en','sv':'lang_sv', }
I want to put this into a modern style product initialisation
(context.registerClass). Looking at this functions API it didn't become
readily apparent how I can pass in these values. This would be nice to do so
I don't have any hacking of dtml to do. Has anyone done this / got any
advice?
Thanks.

[Zope-dev] Storing session objects in a ZODB
I want to store the session objects (from CoreSessionTracking) in the ZODB so that users can save preferences (set in a Session) and call them back later. Just thinking that the easiest way to something is to pickle it, but pickling it in the ZODB which then pickles it, seems daft. Someone suggested I could just _setObject into the ZODB, but don't I still need to make a class wrapper around this? Has anyone tried this? I couldn't spot anything in the CoreSessionTracking API that obvious...

Re: [Zope-dev] Fw: [Zope-dev] Storing session objects in a ZODB
Well my quick hack and wacky of doing it is as follows: - I wrote a quick simple class "ZStore" that has as one of its properties a pickle, which you can read and write to using cStringIO - I make a ZStore object, throw in the session object, it pickles it as the data property, I add a few more useful properties, like title, owner etc... - To get it back I get that object, unpickle that property and I have the session back. Quick hack that works for me and allows me to change the content of a session object, without having to change the storage.

[Zope-dev] Changing Ownership
I have a folder inside a user_info_folder that allows users to store data (these fabled session snapshots of earlier posts). When I create it I want to set the Ownership of that folder to the user. Since a user is created by someone else (only admin can create users), the admin person is becoming the owner. Simple I thought, in python when the object is created, set the ownership obj.changeOwnership(user) where user is: user = self.acl_users.getUser(id) The error I get back is Error Type: AttributeError Error Value: aq_inner ... File d:\Zope23\lib\python\AccessControl\Owned.py, line 168, in changeOwnership (Object: Traversable) File d:\Zope23\lib\python\AccessControl\Owned.py, line 302, in ownerInfo AttributeError: (see above) It would seem ownerInfo is looking for the User context to find the path to the object. Anyway the end result is I can't seem to set the owner. Is there a simpler way to do this. Is getUser actually returning the wrong thing?

I looked at "External Session Data Container" (ESDC) and had some questions here I go: -Why does an ESDC have a session timeout in 20 minutes, yet the cookie lifespan can be 30 days. Surely there will be no way to tie a cookie back up to a session since the ESDC will be have had that person nuked, I was sort of hoping I coudl persist the data in the ESDC for a long time to provide storage (I could always set the minutes to 9 or something silly). I guess if I really want data to be persisted for ever some sort of Membership product will be needed... -Mounting a non-undoable db into Zope is not trivial unless there is something Im missing. There's a non-undoable system every Zope installation has called the file system, why dont we use that? I was thinking we could modifiy LocalFS to provide that sort of functionality would be much easier...

[Zope-dev] Debugging Zope
For all those who questioned my slip of an email a few weeks ago regarding debugging Zope with Komodo, well its official now. A how to and some screenshots are now available: http://www.zope.org/Members/andym/Komodo. I hope you find it as useful as I do.

Set it to this, and set a high cookie timeout. But yes, a better > way to do something like this is to use sessioning in combination with a > membership product. Ah ok, yes the more I thought about it, the more I thought a Membership system is the way to go. > Local filesystem access won't work across ZEO clients.

This doesn't mean someone couldn't write an alternate > data container implementation that uses the filesystem, however. True. But its another option that is quick and easy for many people.

[Zope-dev] manage_options in 2.3
Thanks for the new management interface guys I happily wrote a product last
night and did a quick interface using the standard Folder interface and
fiddled with filtered_meta_types list and dontAllowCutandPaste and so on. A
quick How-To will be on its way. I got a wierd error trying to fiddle with
manage_options though, in the olden days something like this worked:
manage_options = (
( Folder.manage_options[0], ) +
( {'label':'View', 'action':'my_index_html', ) +
( Folder.manage_options[2:], )
)
But I kept getting this error in 2.3:
(Object: manage_tabs)
File E:\Zope23\lib\python\App\special_dtml.py, line 236, in _exec
(Object: manage_tabs)
File E:\Zope23\lib\python\DocumentTemplate\DT_With.py, line 133, in render
(Object: _(manage_options=filtered_manage_options()))
File E:\Zope23\lib\python\DocumentTemplate\DT_Util.py, line 334, in eval
(Object: _(manage_options=filtered_manage_options()))
(Info: filtered_manage_options)
File , line 0, in ?
File E:\Zope23\lib\python\App\Management.py, line 119, in
filtered_manage_options
(Object: Traversable)
AttributeError: (see above)
Error Type: AttributeError
Error Value: 'tuple' object has no attribute 'get'
It seems its looking for a tuple of dicts? But looking at Folder on other
classes their manage_options hasn't changed. I then found this hack worked
(looking at this morning it could be improved):
_m = list(Folder.manage_options)
_m[1] = {'label':'View','action':'my_index_html'}
manage_options = (_m)
Whats going on?

Re: [Zope-dev] Python products
Take a look at FSPoll which has sort of structure... > You may have to do somethign funky if you want to limit the types of object that > appear in the 'Add' list of your new classes. I have no idea how to do that :-S I did that in FSPoll just last night. Basically overrode filtered_meta_types, and iterated through the tuple of objects, discarding ones I dont want, keeping the ones I do. I was hoping to do a how to in the next day or so. -- Andy McKay. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
