sort on multiple columns with Catalog
by Wim Bekker 30 May '03

30 May '03

Hi, I have a nice Catalog that sort pages on Field Scheduled (this is a number grouping pages together). Now I also want the results sorted on Id, probably some other time also on another Field. Can I do this with Catalog or should I write a script? Wim

Use of Client.py
by Encolpe DEGOUTE 30 May '03

30 May '03

Hi, i had got a problem today with lib/python/ZPublisher/Client.py. When it takes a file in the MultiPart function, it look only at the _extmap dictionary to calculate the mime-type. This one is small and there is no method to force the mime-type in that one is not in _extmap. Today i have just add 'application/zip', but i don't think it's the right way to do this. What do you think of this? -- Encolpe DEGOUTE, Ingénieur Logiciel, Nuxeo SARL: Zope Service Provider.

Webdav and winword
by volker.wend＠efgbsh.de 30 May '03

30 May '03

He folks, I try to create a folder in Zope for some folks with winword for shared documents. I thought we could use webdav to access those files and edit them... But each time I open a file from within winword vi the webdav port, winword opens the file in read-only mode. If I create a new file and save that multiple times, everything works fine. Sometimes I even can open the file in read-write mode and than suddently I can only open them read-only. I checked in "WebDAV Lock Manager" but the file is not locked. Any Ideas or hints for debugging ? Regards, Volker Wend

I do not see where you do that, and that is probably why the method does not know about the variable. Within the zsql method, you refer to the parameters by the names you gave them when you added them to the method definition. Also, in the outer code, pbtemp seems to be a dictionary, where as in the zsql method you are treating it as a simple scalar value. So when you do get wi working, in the future you may get confused by the name. I would suggest using a different name for that variable to avoid the confusion. Cheers, Tom P

Hi, The serail number has 3 records (cell_number) I wish to update each record with the proper pbtemp information. My input is still as follows: <dtml-in expr="_.range(3)"> <input type="text" name="pbtemp[sequence-index]" size="6"> </dtml-in> Alexis Roda sent me directly some suggestions that I tried but it produced an error. <dtml-call "REQUEST.set('serial_number', 'mem0314701')"> <dtml-call "REQUEST.set('cell_number', 0)"> <dtml-in expr="_.range(3)" prefix="p"> <dtml-call "REQUEST.set('cell_stack_number', cell_number+1)"> <dtml-call "REQUEST.set('cell_number', cell_number+1)"> <dtml-call expr="testing(parameter=pbtemp[p_index])"> </dtml-in> But I see this error: Error Type: NameError Error Value: global name 'pbtemp' is not defined The zsql is as follows: update atp_fields set pbtemp=<dtml-if pbtemp><dtml-if "pbtemp==''">NULL<dtml-else> <dtml-sqlvar pbtemp type=float></dtml-if><dtml-else>NULL</dtml-if> where serial_number=<dtml-sqlvar serial_number type="string"> and cell_stack_number=<dtml-sqlvar cell_stack_number type="int"> The zsql works when I test it.

First you have to decide what HTML you want to produce. Then you can work out how to generate it. I take it that you want something like this - <tr><td><input name='name1'></td></tr> <tr><td><input name='name2'></td></tr> <tr><td><input name='name2'></td></tr> This is easy - you just put it into the loop you already have - <dtml-in expr="_.range(3)"> <tr><td><input type="text" name="pbtemp[sequence-index]" size="6"></td></tr> </dtml-in> There is no sense trying tp generate anything if you do not know - at least have a good idea of - the results you want. Always work out the html first. If this is not what you had in mind, then please communciate the output you want.

Newbie: Location of External method files
by Vern T Takebayashi 29 May '03

29 May '03

Please excuse my ignorance as I am new to Zope. Is the Extensions folder in the Zope root directory the only place that Python external method files can be located? Or, can external methods be placed in the Extensions folder of a Product (so that they are only visible within the scope of that Product). The reason why I ask this question is that if you have multiple developers storing external methods in the same folder (which can be accessed globally) how do you avoid methods with the same name? A related question I have is about how Zope looks for external methods. It seems that Zope looks along a certain path, in a way that is different from normal acquisition traversal. i.e. you cannot simply locate the external method in a parent folder and expect Zope to find it. If someone could explain how Zope searches for the external methods, I would appreciate this greatly.

Re: [Zope] uploading large files w/ LocalFS
by Gilles 29 May '03

29 May '03

Hello Paul, sorry for having not argumented my reply. The major problem I had with big upload/download is memory consumption: the last time I try it (zope 2.5.1 or 2.6) downloading a 800Mb file (stored on a LocalFS directory) was taking lots of memory. I think the zserver has to keep the complete request/response object in memory before using/sending it. I asked to this list, and got the: "put static/big stuff in apache" reply. This is point 1 of the 2 things I don't like with Zserver/zope. The point 2 is the 'hanging' capability. I think there is no plan to solve these minor annoyances, they are present (afaik) since Zope 0.9.

<dtml-in>, batches and <dtml-unless previous-sequence-start-number>
by Derek Basch 29 May '03

29 May '03

Hello, I am attempting to build a: <<< 1 2 (3) 4 5 6 >>> style batch record control using DTML. I have gotten everything working except for the links to the first and last batches in the previous-batches and next-batches mapping sequences. <<< and >>> respectively. I am able to sucessfully test for previous-sequence-start-number in the affirmative (<dtml-if p.s.s.n>). However, a test in the negative seems to be broken (<dtml-unless p.s.s.n>). Such as in the snippet below. In other words, a hyperlink is inserted if I use <dtml-if> but not if I use <dtml-unless>. Can anyone tell me what I am doing wrong or is this a broken feature? <dtml-call "REQUEST.set('batch_number', 0)"> <dtml-in expr="SQL(q=q)" previous size=bat_size start=query_start> <dtml-in previous-batches mapping> <dtml-unless previous-sequence-start-number> <a href="<dtml-var document_id><dtml-var sequence-query>query_start=<dtml-var batch-start-number>"><<<</a> </dtml-unless> <dtml-call "REQUEST.set('current_batch_number', _['sequence-length'] + 1)"> <dtml-call "REQUEST.set('batch_number', _.int(batch_number) + 1)"> <dtml-unless sequence-start> , </dtml-unless> <dtml-if expr="batch_number >= current_batch_number - 10"> <a href="<dtml-var document_id><dtml-var sequence-query>query_start=<dtml-var batch-start-number>"><dtml-var batch_number></a> </dtml-if> </dtml-in> </dtml-in> <dtml-call "REQUEST.set('batch_number', _.int(batch_number) + 1)"> <dtml-call "REQUEST.set('current_batch_number', _.int(batch_number))"> <dtml-var current_batch_number> <dtml-in expr="SQL(q=q)" next size=bat_size start=query_start> <dtml-in next-batches mapping> <dtml-unless next-sequence-start-number> <a href="<dtml-var document_id><dtml-var sequence-query>query_start=<dtml-var batch-start-number>"><<<</a> </dtml-unless> <dtml-call "REQUEST.set('batch_number', _.int(batch_number) + 1)"> <dtml-unless sequence-start> , </dtml-unless> <dtml-if expr="batch_number <= current_batch_number + 10"> <a href="<dtml-var document_id><dtml-var sequence-query>query_start=<dtml-var batch-start-number>"><dtml-var batch_number></a> </dtml-if> </dtml-in> </dtml-in> Thanks, Derek Basch __________________________________ Do you Yahoo!?
