Looking for Zope & Python Gurus' Résumés, SVP
by Chris Abraham 26 Oct '01

26 Oct '01

ZPugs and PIGies: I would like to have a file of Python, and Zope coders who are available for short-term, long-term, contract, sub-contract work, project-based, and "crap, it broke can you fix it?" work. Either in the Washington Metro Area or via Telecommuting. If you are out of the DC-Area, please send your résumé anyway, and I will keep it on file. I am getting lots of requests and I want to make sure that I have loads of people who might be interested in the projects. Please send your résumé and an hourly, day, and salary range and I will do what I can. Cheers, Chris Abraham -- chris abraham <cja(a)dds.nl> washington, dc 20003-0163 united states

Login Form?
by CJ Kucera 25 Oct '01

25 Oct '01

Howdy! I was wondering what I should look at to be able to do a form-based login such as the one found at www.zope.org. I've looked around the zope.nipltd.com archives and it seems that LoginManager might be the right thing to use, but using the "view_source" method at www.zope.org doesn't seem to incorporate any of that, so if someone could point me in the correct direction, I'd appreciate it. Thanks! -CJ WOW: Rapacious | A priest advised Voltaire on his death bed to apocalyptech.com/wow | renounce the devil.

sqltest op=like problems
by alex＠quad.com.ar 25 Oct '01

25 Oct '01

I'm trying to perform the following: SELECT * FROM table <dtml-sqlgroup where> <dtml-sqltest terminal op=like type=string optional> <dtml-and> <dtml-sqltest principal op=like type=string optional> <dtml-and> <dtml-sqltest product op=like type=string optional> </dtml-sqlgroup> if I pass only terminal and product I get the following: SELECT * FROM table WHERE terminal like 'foo' AND product like 'bar' but I need it to render like this: SELECT * FROM table WHERE terminal like '%foo%' AND product like '%bar%' so I read the mailing list archives and found out many people is doing a <dmtl-let fieldName="'%' + fieldNamel + '%'"> but this would break my optional attribute.. here's an example result using let on each field and passing only terminal and product as parameters: SELECT * FROM table WHERE terminal like '%foo%' AND principal like '%%' AND product like '%bar%' this is not tolerated since the principal field might be null, and doing a like '%%' would discard those entries. so, shouldn't dtml-test get patched to support at least the following op attributes: op=like_begin ( like '%foo' ) op=like_end ( like 'foo%' ) op=like_any ( like '%foo%' ) or is there any solution for this already? thanks Alex

RE: [Zope] can't store a date in Access database

As a point of reference, you can use reserved words if you enclosed them in brackets [Date]. The one I run into most often is [Desc] Looks like everyone was shortcuting their posts.

Thats it! 'Date' is a reserved word.

Won't that screw things up? Also - is the SQL statement expecting a ; at the end of it? Again I seem to remember access throwing fits when I tried to type in my own SQL statements and forgot. hth, Laurie

RE: [Zope] Stand-alone dedicated client for Windows?
by sean.upton＠uniontrib.com 25 Oct '01

25 Oct '01

A few random thoughts... Potentially, Zope has a lot to offer for building fat-client frameworks, but not a lot of support for a fat client MI. Personally, I think Zope as a front-end to ZODB has good potential in a data-center environment serving GUI clients in the web-services future, and that with this in mind, development frameworks ought to exist to make this as easy as possible to jump into (one can hope; perhaps someday when I get some time, I will try to implement something like this). I think part of the problem is that Zope really ends up being a toolkit for most folks - and one used in a variety of different ways - and a GUI toolkit would place restrictions on this and require a lot of work to address working with each and every Zope product. I think the solution for GUIs is really a responsibility/option for the application layer (i.e. Each Zope product), though there could be a set of tools created for generic Zope tasks for developers (only as an IDE); I think Boa Constructor is the most likely candidate for that. If you want higher-level stuff, you really need to code a custom GUI fro your product, or look into using the CMF with document editing software that supports FTP and/or WebDAV; what is most needed in this regard is not a one-size-fits all client, but a bunch of documentation and examples to make it easier to do this on your own. Developing custom GUI applications with Zope using Boa Constructor, wxPython, and XML-RPC could have very interesting possibilities, and perhaps what is needed is drag-and-drop components for doing this in Boa-Constructor that allow data-binding to XML-RPC calls, like the way Borland RAD tools bind RDB datasets to visual components... Python 2.2 will include XML-RPC support (but you would have to extend it with http basic-auth support), so Python 2.2 packaged together with wxPython for Windows in a unified installer would be a nice start for deploying an application using that as a framework; as for me, I just apt-get install, but it would be nice to be able to build GUI apps that could be deployed by having an installation program spawned to install all the prerequisites.

RE: [Zope] Zope Eats Memory
by sean.upton＠uniontrib.com 25 Oct '01

25 Oct '01

Are you using REQUEST.set() a lot? I am (my presentation code, unfortunately, uses these quite aggressively). I have dtml that wraps other DTML "core" presentation widgets, and I use <dtml-var "REQUEST.set('foo', '')"> a lot. Does anyone know if there is another, more graceful, way to pass parameters from a wrapping dtml method to a dtml method it calls? Also, slightly related, as I eventually plan to migrate this particular site to ZPT: are there any issues with reference leaks with tal:define similar to REUQEST.set() calls?

RE: [Zope] Loginmanager Installation Problem(despirate for help)
by Stuart Nicholson 25 Oct '01

I believe you need to update the ZPatterns Product as well. I'm using LoginManager successfully under Win32 Zope 2.4.1 but it requires the latest versions of both LoginManager and the ZPatterns product to resolve all the issues. You mention you've applied some patches, just for Login Manager? Or for http://cvs.eby-sarna.com/ZProducts/ZPatterns/ also? Hope that helps?

I appologize for my careless typos. I should have copied and pasted the code. Here is the copied text: insert into TableName(Date) values ('10/25/2001') The quotes were in fact single quotes. Yes the name of the table is really 'TableName', however this was just created to help tackle my problem. The real SQL statement has 20 fields to fill. I wanted to isolate the problem so I made a silly table named 'TableName'. You're right that I should not need a key for this test to work. I am sure the SQL is correct because it works fine in Java. Just not in Zope, it yeild the error: Error, sql.error: ('37000', -3502, '[Microsoft][ODBC Microsoft Access Driver] Syntax error in INSERT INTO statement.') Micah From: "Thomas B.

You need the actual name of the table. You also probably need to supply the primary key or index column value as well as the date column - definitely if there is a primary key or an index (there ought to be one, but in Access you can get away without a primary key). Finally, you need to use single quotes instead of double quotes around the date value. Double and single quotes are not interchangable in SQL. So if your table is called "fact_table", and its primary key or index column is called "the_key" whose value should be 102 for this row, and if the date field were called "Date", then you would write insert into fact_table (the_key,Date) values (102,'10/24/2001') Access will accept this syntax for a dattime field, as I just verified by checking. If you mean to be changing an existing date value, you need to use an update statement instead. Cheers, Tom P
