Updating one data.fs from another
by Graham Chiu 23 May '00

23 May '00

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I do development on my site on my notebook, and then rather than overwriting my production data.fs, I then manually make the changes to the production data.fs by create/cut/paste from my development data.fs which is all very painful. I tried ftp'ing into my development site, but some things like TinyTables are 0 bytes in size and can't be accessed. My browser also doesn't support cut/paste of whole documents from one data.fs to another, just the data whereas it supports this within a data.fs. Is there some other way to propagate changes from a development site to a production site? - -- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.co.nz/index.php Powered by Interbase and Zope -----BEGIN PGP SIGNATURE----- Version: PGPsdk version 1.7.1 iQA/AwUBOSlQv7TRdIWzaLpMEQKLPQCfWcsRKQkXIP5nwaRuetiqpJ/PQ/oAoJf+ q0bL2DJvxMEceE8fCtupQPuq =kroL -----END PGP SIGNATURE-----

SQLSession Problem
by wai＠mahirnet.com 23 May '00

23 May '00

Hi All, I'm using zope 2.1.6 with apache server on NT platform. and I had a problem with SQLSession. I tried to put in the '_force_new_session' flag whenever I called a session, so I can have a fresh SessionID. But I always got a error return with a message "TypeError". So I wonder if this is the correct way to call the session component : <dtml-call "Session('_force_new_session=1')"> Please help. Cheers Wai

Actually, it *is* possible still to add the test_project objects; the problem is that the management interface is confused about the list of possible options. To prove this to yourself, follow Eric's recipe above, and then invoke the add form directly through the URL, e.g.: <URL http://my.site/a_test_folder/a_test_project/manage_addProduct/test_product/…> If you fill out the ID and press 'Add', le voilà! The management interface is using some unhappy heuristics in its attempt to determine the legal set of addable classes: * In the initial case, the only possible item is test_project, so it hard-wires the "Add" button to it (and doesn't show a list!) * In the second case, the "nested class rule" kicks in before the MI gets up to the top of the product, and so the nested "project team" class is the only one found; again, the MI wires up the "Add" button directly, with no list. * If you had more nested classes, you would see a list of them (but still not the project class itself). Likewise, if you add other meta-types to the "Subobject" tab of the class, they will appear in the list as well. This problem is a ZClass bug and should be reported to the Collector: http://classic.zope.org:8080/Collector (Actually it looks like a duplicate of #811).

Deleting folder-like objects.
by John Morton 23 May '00

23 May '00

After a few experiments, I've observed a couple of things about deleting folder-like objects: 1) You can delete them with the same practiced easy as any other object, along with everything in it. No 'Are you sure you want to shoot yourself in the foot' dialogs, or anything. (How hard to implement with manage_beforeDelete?) 2) Deleting a folder effectively removes everything under it (well, you can't navigate to them, AFAIK), but it doesn't invoke the manage_beforeDelete methods of it's decendants. Any reason for this, or should I proceed straight to the bug collector? John.

Q; Date / ZCatalog / Search
by Jørgen Skogstad 22 May '00

22 May '00

Kindest sir, I have a small question I hope someone could share some wisdom with. I am not that familiar with the various objects available within the Zope framework yet. .. I have made a ZCatalog which works seamlessly for text only searches etc. However; I need to search on a date basis on the generated object in the ZCatalog. For now my "date" entry/column is [string] coded.. not "date" as would be apropriate? How can I use date .. and then make a search to get the last 5 entries in a table? http://www.zope.org/Members/Zen/howto/AdvZCatalogSearching .. shows some possible ways to do this; but I can't seem to get them to work properly; <dtml-comment> Items modified in the last 14 days </dtml-comment> <dtml-in "Catalog(bobobase_modification_time=_.DateTime(date)-14, bobobase_modification_time_usage='range:min')"> New item: <dtml-var "Catalog.getpath(data_record_id_)"><br> </dtml-in> .. does anyone have any information on how they have used this and gotten it to work? .. and might have an example or two? ;) What exactly does the various elements in the above example do? .. like "Catalog(bobobase_modification_time=_.DateTime(date)-14, bobobase_modification_time_usage='range:min')" ?? .. mm .. any input? ;) Thanks in advance.. Kindest, Jørgen Skogstad

RE: Generate edito form from dtmlDocument : property type
by Dr. Ross Lazarus 22 May '00

22 May '00

I think the general idea of automating html generation for data entry web forms is a very good one, but IMHO it's heroic to even think about doing this sort of stuff in dtml!! (This discussion probably should be moved to zope-dev?) I've got something which generates useful DTML and ZSQL code automagically from ZClass BASIC propertysheet contents and so can be used to do the grunt work for making zclass add and edit methods. It generates ZSQL code which is only tested for the sybaseda but would be relatively easy to tweak for other DA's It uses a single python external method - have a look at http://www.zope.org/Members/rossl/ZClassExtender for an example of what's possible...feel free to extend it?!!

how do you iterate over tiny tables?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a folder full of Tiny Tables.
