IIRC they use <dtml-in "objectValues(['article'])" size=3 sort_expr="skey" start=query_start> i.e. sort_expr instead of sort. Unfortunately I can't find any documentation besides the src of DT_in.py about it's functionality. cheers, oliver

RE: [Zope] DTML-IN not using SIZE parameter in HDML coding.
by Schmidt, Allen J. 13 Jul '01

Been to the archives several times and have run across this, too. But, if there are 20 records and I say size=4, I don't get just 4. If I know there are 8 records and I say size=2 I get all 8. I have tried several combinations but each comes back with too much data as it is ignoring the SIZE. -----Original Message----- From: Paul Zwarts [mailto:paz@oratrix.com] Sent: Friday, July 13, 2001 10:25 AM To: Schmidt, Allen J.; zope(a)zope.org Subject: RE: [Zope] DTML-IN not using SIZE parameter in HDML coding.

Its all done in Zope. The application works great. It asks you for part of a company name to search for, submits and queries a database and returns a list of company names that match. However, it seems to be ignoring the size parameter of the dtml-in tag. So long at the list is fewer than 10 it works fine. If over that, the phone can't handle the display of the page and throws an error. Not a Zope error but one from the phone. Any idea why size would not work with HDML?

Number of bytes... If there is only a small line returned for each of 20 rows...this will be less than the 1400 (should be much less...) Could if have anything to do with the number of rows ZSQL 'grabs' for the query? I'm referring to the Advanced tab now. Anything to do with this there? The size of the page should be determined by the number characters I present to the 'browser' right? If I have just two words for each line times, say, 20 lines, that should not overload it. Aside from this small thing, Zope makes it so nice to write pages for the phone. Several major things are planned and the list keeps growing as we discover new things we can do.

Mobile pages like HDML/WML has page size limits, which use to be the problem. The size attribute of the dtml-in tag doesn't ensure you a target page size, which depends on the number of all the characters within the page, including WML/HDML tags. For WML the page size limit is 1400 bytes. Ausum "Schmidt, Allen J." wrote: > > I'm working on an HDML page to displayed on a WAP-enabled phone. Its all > done in Zope. > The application works great.

Re: [Zope] ftp problem: ZServer unhandled connect event??
by Li Dongfeng 13 Jul '01

13 Jul '01

Thanks for the speedy patch. That solved most of the ftp download problem. To improve, there are still something we can do: 1. When running Zserver in debug mode, some ftp transfer will give out: PROBLEM(100) ZServer unhandled connect event message. 2. When run in ftp-passive mode, some large files(above 350KB) still cannot be retrieved, but no problem in non-passive mode. I'm not sure if this is due to Zserver or my linux network configuration. 3. Some objects cannot be downloaded, like "acl_users", but retrieving them will cause the batch process to stop. Of course this is related to the ftp client in use. Maybe we can give a default download action for un-downloadable objects, like just creating a zero-length file?

Virtual Host Monster but wrong Root Folder returned by PARENTS[-1]
by Justin Heesemann 13 Jul '01

13 Jul '01

Hello, i am using zope 2.4.0b2, having a virtual hosting monster in my root folder. in my root folder i have a folder called "host.com" (and i want to add otherfolders for all other domains). i'm using a rewrite rule in apache which says : RewriteRule ^/(.*) http://my.host.com:8080/VirtualHostBase/http/www.host.com:80/host.com/Virtu… [P] Ok, everything is fine so far. i then have created a small dtml method in the folder host.com, which i call "RootNavigation" as it should present a small navigation bar, listing all folders in the root dir (which I think should be "/hosts.com"). RootNavigation : ---------- <dtml-with expr="PARENTS[-1]"> <dtml-in expr="objectValues('Folder')"> <a href="&dtml-absolute_url;" class="prim"><dtml-var title_or_id></a> </dtml-in> </dtml-with> ---------- Unfortunately, when i point my browser to http://www.host.com i don't get a list, of the folders residing in /hosts.com, but a list of the domains (including host.com) which i have created as folders in the Zope Root Dir. So it seems that PARENTS[-1] is not pointing to the /host.com folder. Any ideas how to change that ? Best Regards, Justin Heesemann

POST to zope

Can someone suggest a document somewhere that outlines Zope mechanism for POST and GET? I'm trying to make POSTs to Zope from elsewhere without any ideas of how to go about it. Thanks, Paul Zwarts

Re: [Zope] Choice of the sorting key of a dtml-in tag
by Jean Lagarde 13 Jul '01

13 Jul '01

Hi Benoit, My first answer post! Although I haven't tried that yet, my understanding is that 'sort' only accepts constants, i.e. it will interpret skey as the literal 'skey', not as its value. You need to use the undocumented 'sort_expr' instead, i.e. <dtml-in "objectValues(['article'])" size=3 sort_expr="skey" start=query_start> I'm not sure if you can include 'reverse' in skey; you probably have to state that separately in the dtml-in tag. Hope that solves your problem, Do a search on sort_expr on this list for more details.
