Note, if your Zope is in BBO_DEBUG_MODE it *will* reload all it's DTML scripts if they've changed on the filesystem, it will not, however, reload the actual code. This require a shutdown. It's not much of a pain if you don't do lots of micro-incremental adjustments to you code all the time. Once a code base is stable, it typicly doesn't change much. You can submit this to the Collector, and see if it can be a next release feature. http://www.zope.org/Collector -Michel > > Alexander Staubo > http://www.mop.no/~alex/ > mailto:redhand@mop.no > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

Preventing Zope from caching product?
by Alexander Staubo 12 May '99

12 May '99

It's really annoying having to restart the Zope process all the time when I'm working on a product -- because the product script is being cached by Zope, I have the restart the process every time I make a modification. Is there a way around it? Putting Zope is a no-caching debug mode would have been nice. Alexander Staubo http://www.mop.no/~alex/ mailto:redhand@mop.no

Re: [Zope] reverse sort
by Luciano Ramalho 12 May '99

The following external method has proven VERY useful for us at Hiperlogica. I believe it does what you want. ____________ WHAT IT DOES The function returns a list of documents in a folder, sorted by a 'pub_date' string attribute which must be present in all documents. The sort order is descending. A property of type 'list' named 'exclude' can be used to list the id's of documents which should not be listed. _____________________ HOW TO USE IT IN DTML To generate a list of titles with links:  <A HREF=""></A>  To generate a similar list, but looking inside a folder called 'folder1':  <A HREF="folder1/"></A>  To generate a list with only the tree most recent documents of the current folder:  <A HREF=""></A>  ____ NOTE We did not use the actual date of the document because (1) we did not know how to obtain it and (2) our customer wanted to be able to alter the date. We used 'pub_dates' formatted like this: '1999/05/12 14:32:02'. You could put anything inside pub_date to determine the sort order. ___________ SOURCE CODE def hx_list_docs(self, max=0): dic = {} #find documents for doc in self.objectValues(['DTML Document']): #collect if it is not in the exclude list if not ( doc.id() in self.exclude ): dic[doc.pub_date] = doc dates = dic.keys() dates.sort() dates.reverse() list = [] for date in dates: list.append( dic[date] ) if (max != 0) and (len(list) == max): break return list -- Best regards, Luciano -- Hiperlógica <http://hiper.com.br> Automação de web-sites || Web-site automation

reverse sort
by benjamin.ryzman＠easynet.fr 12 May '99

12 May '99

Hello from a new Zope user! I'm currently playing with the idea of implementing a sort of Slashdot community in Zope. I've just started DTML scripting and External methods but my experience with python is limited. I'd like to get a sequence of the DTML Documents in the current Folder *reverse* sorted by an attribute. Is there an easier way to do it than to write an External Method. I find it difficult to believe that the "in" tag gets a "sort" attribute but not an "rsort". Also I cannot use the python reverse() method in an expr since this method reverses in place (and thus returns None). What I was going to do was:  ...  which doesn't work.

RE: [Zope] IE5 form entry horror.
by Alexander Staubo 12 May '99

Why is this a problem? It's a client security problem, not something that hits the server in any particular way. If the desktop user configured his computer so that anyone can reclaim his password from the autocomplete list, that's his problem. You could "fix" Zope, but it wouldn't fix the thousands of other web sites which also do credit card. Afaik, autocompletion on forms is disabled by default.

You can patch ZPublisher anyway you want, the question is if it will get into the official product. This will require much thought on our part, on the one hand it solves your specific problem and possible solves problems for lots of other people using that browser, on the other hand, it would be a step of obfuscation. Perhaps it could be made a modular solution? Go ahead and send the patch to the list, I'd be curious to look at it. -Michel > Anthony > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

IE5 form entry horror.
by Anthony Baxter 12 May '99

12 May '99

one of the customer service people here just pointed out something of a horror problem (a week before go-live, yay). IE5 appears to have a client-side cache of form entry values - so if someone returns to a page, they get a drop-box of previously entered values for this form field - this occurs even on a form accessed by https. To say that I'm somewhat unimpressed by this utter misfeature is something of an understatement. Imagine a kiosk setup, with a registration screen prompting for (amongst other things) a credit card number. Gee, let's use one someone entered earlier - pull down a little scrolly box. aiieieieie. One thought that comes to mind is to make the form field name be a name with a random bit on the end. (Another thought that came to mind was to do a drive-by on the local MS office.) Anyway, the reason for the zope-post is that I'm thinking of hacking the field name converting so that you can do fieldname:type:end:anything and just finish looking for the type name after it hits the 'end' tag. This is a 3 line patch to ZPublisher/HTTPRequest.py - would it offend anyone if it was added? Anthony

Object references
by Robert Leftwich 12 May '99

12 May '99

What is the Zope way of holding references to objects in another object. Using the following ordering entry system as an example : Catalog contains zero or more CatalogItems CatalogItems are structured as CatalogItemNo, Description, UnitPrice, ... Order contains OrderNo, OrderDate, zero or more OrderItems, ... OrderItems are structured as CatalogItem, Quantity, ... What should the link between OrderItems and CatalogItems be ? In relational databases you would store the CatalogItemNo and in object databases a CatalogItem object reference. Given that I am using the Zope object database, how do I store a reference to a Zope CatalogItem object ? If it is possible to store the object reference, this gives rise to another question, how do you maintain the referential integrity of such a system, e.g. what do you do if someone deletes a CatalogItem that is used by some orders ? Thanks in advance Robert Leftwich
