TransientObjectContainer.keys()
Hi, I'm using Zope as an application server for some weird, non-Web-related stuff. TransientObjectContainer really matches my needs for a particular problem (the dict-like interface and the auto-delete feature are quite useful), but TransientObjectContainer has no keys() method. I can see why this is the case considering sessions, but it's something that I absolutely need for my application. I assume my options are: o Hack Zope and submit a patch. o Hack Zope and don't submit a patch, because it won't be accepted. o Figure out some (really inconvenient) way to store a list of keys in the TransientObjectContainer. o Don't use TransientObjectContainer, just use normal Zope objects. Use a cron job to implement auto-delete. I welcome your advice. Best Regards, -jj -- Hacker is to software engineer as Climbing Mt. Everest is to building a Denny's there.

TransientObjectContainer does have a keys method. At least in Zope 2.6 and the Zope trunk it does... On Thu, 2003-03-06 at 16:53, Shannon -jj Behrens wrote:

Chris, Thank you for your reply! I'm using 2.6. According to the API docs, TransientObject has a keys method, but TransientObjectContainer doesn't. Looking at TransienceInterfaces.py confirms that TransientObject implements DictionaryLike whereas TransientObjectContainer doesn't. Am I confused?

Isn't TransientObjectContainer a container for TransientObjects ? You get the auto-delete from TransientObjectContainer. I assume (without looking at the code) that the dict in TransientObjectContainer stores some sort of references to TransientObjects ... which you then use ... I could be very wrong ... since I'm not taking the time to read the code. On Thu, 2003-03-06 at 19:02, Shannon -jj Behrens wrote:

All of your statements are correct. However, I still know of no way to way to get a complete list of TransientObject's from the TransientObjectContainer. (This should not be confused with getting a list of keys from *an individual* TransientObject). Please set me straight if I'm wrong. Thanks, -jj

I think the problem is in Zope/lib/python/Products/Transcience.

That's right. The method has no security assertions so it's 'private' to "through the web" code like Python Scripts and ZPT. I'd suggest reading the Zope Developer's Guide Security chapter to get an understanding of how to change this. On Fri, 2003-03-14 at 13:21, Shannon -jj Behrens wrote:

Your advice is very helpful, although the documentation is quite complex. The documentation inspired me to just create an external method that accepts a TransientObjectContainer and returns the result of its keys method. How badly does this screw me?

Why not use the external method to just obtain the result you want, eg: def toc_keys(self): return self.temp_folder.session_data.keys() On Fri, 2003-03-14 at 15:23, Shannon -jj Behrens wrote:

No, unfortunately, it doesn't. Despite the fact that I'm logged in as a manager, it asks me for my username and password. See below.
The above should print the TransientObjects in the TransientObjectContainerInstance....
Again ... I've never read the code ... but that's the way session works...
I think the problem is in Zope/lib/python/Products/Transcience. Whereas the get method is declared as:
security.declareProtected(ACCESS_TRANSIENTS_PERM, 'get') def get(self, k, default=_marker):
the keys method is declared as:
def keys(self):
Notice that there is no security declaration. I think that this combined with the line:
security.setDefaultAccess('deny')
is locking me out.
Of course, this is my first time looking at the Zope code, so I could be wrong. In any case, it's not working. :(

Yes.

All of your statements are correct. However, I still know of no way to way to get a complete list of TransientObject's from the TransientObjectContainer. (This should not be confused with getting a list of keys from *an individual* TransientObject). Please set me straight if I'm wrong.

Duh :D Thank you! I am now quite happy! Best Regards, -jj On Fri, Mar 14, 2003 at 04:44:41PM -0500, Chris McDonough wrote:
Why not use the external method to just obtain the result you want, eg:
def toc_keys(self): return self.temp_folder.session_data.keys()

Your advice is very helpful, although the documentation is quite complex. The documentation inspired me to just create an external method that accepts a TransientObjectContainer and returns the result of its keys method. How badly does this screw me? I assume any keys method of any object is no longer safe.
