zmysqlda make failure

You guys really helped in an excellent way. Thanl you very much. Here is what I did. mysql3.22.27 did not work. Mysql-3.22.25.1-rpm worked like you said. That is what did it. I installed the MySQL-3.22.25-1 untared the Zmysqlda from /Zope. Went to /Zope/lib/python/Product/Zmysqlda/src and ran the two make steps. Then I untared the mysqldb_0_1_0 and installed it. And ran the patch. Then I was able to see the Zmysql objext to add from the zope manager. thanks alot for your help. cj technology.nospam(a)mylinuxisp.com

zope not working with wingate 3/winsock?
by Rowan Hick 22 Dec '99

22 Dec '99

All, Anyone tried running Zope on a 98 machine with Wingate 3.0 Client running? I think this is causing my zope to fall over (to be more correct not starting) as if I use it on a 98 machine without a Wingate 3.0 Client running it works fine n dandy.. I've tried switching off the wingate 3.0 client, and adding python.exe to it's list of "excluded" programs.. all to no avail... Would be neat if I didn't have to keep swapping windows directories to run Zope, so if anyone has got around this problem please shout out. Ta Rowan

Zope recommended by LinuxWord as "discriminating geek" gift
by Ben Glazer 22 Dec '99

22 Dec '99

Just wanted to point out that Zope is the holiday gift recommended by LinuxWorld for Web developers who love Linux. A very flattering review accompanies the gift suggestion: "Zope is dope. Here is a complete publishing system that has been used successfully by many sites. The Python programming language, which serves as the interface for building complex scripts with Zope, is both easy to learn and easy to compile for really fast execution. Zope provides all you need to create an intelligent Website, including the necessary tools, discussion forums, database interfaces, DHTML coding, integration with XML and objects, and so on. With all it does, this tool could fetch thousands of dollars, but Zope provides it for free."

dtml-tree bugs?
by Sam Gendler 21 Dec '99

21 Dec '99

>From playing around with dtml-tree tags, it would appear that there are some small bugs. I had problems using branches-expr. The namespace inside the tree tag was not from the object in the tree, but from the object containing the tree. Writing code in python that called objectValues, and then calling that from the branches= attribute of the tree tag fixed that one. However, I have another similar problem. Each object in the tree (a zclass called Cpi), contains a dtml-method called outline-string that returns a string. This method works fine when called directly from the containing object. However, when my tree is iterating through all of the Cpi objects, calls inside the tree tag to the outline_string method always result in the outline_string tag from the CPI containing the dtml-tree rather than the Cpi's contained by the tree (each Cpi contains other Cpis) The dtml-tree code is as follows: <dtml-tree branches=cpiBranches> <a href="<dtml-var absolute_url>/web_script"> <dtml-var outline_string> <dtml-var title_or_id></a> </dtml-tree> absolute_url and title_or_id render correctly for the class, but outline_string always renders from the class containing this code. I assume that the namespace doesn't grab dtml-methods correctly. While I am at it... How do I access the PARENTS object of a ZClass from inside python code? My ZClass uses code that is almost identical to the ZDiscussion Base Classes for base classes, and then has 2 ZClasses (equivalent to Topic and Item in ZDiscussions) based on the python code. I suspect the tree code would work if I called a python method instead of a dtml one, but I have no idea how to access the PARENTS object from within the code. I was unable to reference it as self.PARENTS or to pass it to the function. \ --sam

I'm developing using a cycle like this: > > * change .py file in lib/python/Products/* > > * save changes > > * restart Zope (takes 10 seconds :-() Also, forgoing the overhead of firing up Zope and accesing it with HTTP makes debugging and hardcore python level development much easier. You can do this by running Zope directly in a python interpreter by using the Zope 'debugger'. (This is the last time I do this demonstration, someone better write a how-to!) [michel@aldous python]$ python1.5.2 Python 1.5.2 (#1, Apr 14 1999, 10:34:26) [GCC 2.7.2.3] on linux2 Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam (You are now in python) >>> import ZPublisher, Zope (This 'runs' Zope) >>> ZPublisher.Zope('') (This fetches the index_html method in the root folder. Identical to accessing just the root level folder of your Zope *through the web*) <html>......</html> >>> ZPublisher.Zope('', d=1) (This puts you in the debugger) * Type "s<cr>c<cr>" to jump to beginning of real publishing process. * Then type c<cr> to jump to the beginning of the URL traversal algorithm. * Then type c<cr> to jump to published object call. > <string>(0)?() pdb> (Just like it says, you can step into the debugger and continue to the first pre-set breakpoint, which is right before the publisher kicks in. The second breakpoint is before the URL is traversed, and the third (and most useful to product developers) breakpoint is right before the discovered object is called) The Zen of Zope debugging is pretty deep, but actualy very easy to grasp IF you know how to use the python debugger BEFOREHAND. 90% of the complexity of debugging Zope is knowing how to use a command line debugger like python's (anyone familar with gdb should feel at home). -Michel

sqlgroup usage question
by Chuck Burdick (TT) 21 Dec '99

21 Dec '99

After reading about the <dtml-sqlgroup> tag and trying several arrangements, I am confused how it works. Here's the problem: Suppose I have a ZSQL method called 'list_employees' as follows: Arguments: id lastname select employee_id, firstname, lastname from employees <dtml-sqlgroup where> <dtml-sqltest employee_id optional type=int> <dtml-or> <dtml-sqltest lastname optional type=nb> </dtml-sqlgroup> Suppose also that I have a dtml method called 'mydtml' as follows: <dtml-var standard_html_header> <dtml-in list_employees> <dtml-var employee_id> = <dtml-var lastname>, <dtml-var firstname><br> </dtml-in> By the ZSQL guide, I would expect that I could call the dtml method in any of the following ways and get the desired result: http://myzope/some/folder/mydtml <<This should list all employees>> http://myzope/some/folder/mydtml?employee_id=5 <<This should list employee number 5>> http://myzope/some/folder/mydtml?lastname=Smith <<This should list all employees w/ lastname Smith>> However, none of these work. In each case, I get a 'Bad Request' error for one or both of the arguments. If I do not put 'id' and 'lastname' in the arguments list for the ZSQL method, then for any request, I get the full list of employees. According to the ZSQL Guide, that is because optional sqltest variables that are not listed in the 'Arguments' list are sought from properties in the current folder. Any hints on how I can achieve the desired functionality? Thanks, Chuck Burdick Web Administrator / Developer Trading Technologies, Inc. chuck.burdick(a)tradingtechnologies.com (847) 424-8844
