I'm not sure I understand the problem you want to solve, but have you tried:  If the folder is one of your ancestors (ie above you and in your path) you can just reference it's attributes like they were your own. If the folder you are targeting is above you but not in your path (ie not an ancestor) but is a child of one of your ancestors, you must first aquire the folder, and then reference it's property, like this:  The rule is: If a folder is an ancestor of yours, you can just say  If a folder is a child of one of your ancestors, but not one of your ancestors (like a cousin), you can say , because you must first aquire the folder. Remember that when it comes to aquisition, DTML Methods and DTML Documents behave differently. Documents aquire from their perspective, and Methods aquire from the perspective of the folder than contains them (Note: see the ZDP FAQ entry on the difference between Methods and Documents). -Michel > name is the property, and candidate1 is the folder id. > > I have tried _.namespace and the #with and #in tags, all have the same > problem. > > Here is the traceback > >  > > Do I have to know the folder that separates the hirearchy and put that > in somewhere? > > Zope-on! > > Jason Spisak > webmaster(a)mtear.com > > _______________________________________________ > Zope-Dev maillist - Zope-Dev(a)zope.org > http://www.zope.org/mailman/listinfo/zope-dev > > (For non-developer, user-level issues, use the companion list, > zope(a)zope.org, http://www.zope.org/mailman/listinfo/zope ) >

Pb using Document Template
by Stephane Tallard 10 Mar '99

10 Mar '99

Hi all, I have a problem using DocumentTemplate.String. I try to use the python extended string syntax use it to generate C++ code . I want DocumentTemplate to call a method for me and put the result in the output file. But unfortunatly the doc is not that clear for that particular use. I'm not sure that anyone here uses DocumentTemplate in that way ... Could you check my example code , where french people will recognize typical french idioms, and tell me where is the misuse ? The resulting error message is : Document Template Parse Error: Document Template Parse Error: Invalid attribute name, ""_['toto'].myprint()"", for tag %(call "_['toto'].myprint()")s, on line 2 of <string><p> Note that the first call doen't make an error, but is not interpreted as a command. Thanks Stephane my code ====================== import DocumentTemplate l__att_type= "ATTTYPE" l__att_name= "ATTTRIBUTE" l__att_member_name = "ATTRIBUTEMEMBER" results = """\ %(call "coucou()")s %(call "_['toto'].myprint()")s """ class TOTO: def __init__(self): self.coucou = "coucou" print self.coucou def myprint(self): print self.coucou toto = TOTO() def coucoucoucou(): print coucoucou dic = {'is_date_att':1,'att_type':l__att_type,'att_name':l__att_name,'att_member':l__att_member_name, 'toto' : toto} print dic print dic['toto'].myprint() print DocumentTemplate.String(results)(None, dic)

[DTML] I give UP!!!! (well, almost... ;))
by Butch Landingin 10 Mar '99

10 Mar '99

I've been trying to figure this out, and I've given up (at least for the day...:(). How do I change the value of a temporary variable that I created with a namespace method? e.g.:      ...      ... I tried the following and they don't work :   I've tried to look at the dtml of all the products I've d/l'ed and also at the proto-FAQ but I haven't found one that exactly does this. Thanks in advance to any DTML guru(s) who can help me this... Butch Landingin butchland(a)yahoo.com _________________________________________________________ DO YOU YAHOO!?

It will continue to accept new connections. If all those connections need to wait for a single-threaded database server, then you don't gain much by running in multi-threaded mode. >Even if ZHS doesn't block completely, more and more queries can pile up. Right. >ZHS has no capability to limit the number of simultaneous threads, Yes, but ZServer does.

While it would appear at first that running a multi-threaded >ZHS would be a win (allows short-running stuff that can be handled >completely by the published module to complete), I think the bad (nay, >catastrophic) failure mode suggests otherwise. I'm not sure how things would work out in real life. I suggest you do some tests to see how things perform under a heavy load. If ZHS is creating too many threads, you might want to switch to ZServer. If you don't like running alpha software, you might want to change ZHS to use a thread pool, which wouldn't be very hard. (Not that I'm volunteering ;-) Otherwise, you might want to start caching results of your database queries, this could potentially help you quite a bit, no matter what server mix you end up using. Finally, I have no idea what your database server is like, but if there are any easy ways to make it multi-threaded or simply faster, go for it ;-) It sounds like this is where your performance bottleneck lies. Good luck. -Amos
