[Zope] Selection and Lines Properties for DTML Docs

[Steve McMahon]

I'm new to Zope and am interested in the use of document properties
for separating content and design in documents (i.e., using  in the "edit" tab to insert properties defined on
the "properties" tab>.

I've had success with simple text properties and would like to be
able to present the user with selection properties (choice 1, choice
2, ...). That works well when I first define a "lines" property, then
a "selection" property. But, what I'd really like to do is hide the
lines property from the user. I've tried putting a lines property in
another document, then setting the selection value
to 'source_doc.lines_prop'. That yields an error "No select variable
source_doc.lines_prop."

Any ideas on the right way to do this? Please feel free to point me
to good documentation!

In this case, I just meant that it shouldn't appear in the properties list 
for the particular page. I want to give the editor of the particular page's 
properties the ability to make a selection, but not the ability to change 
the list of possible selections.

You're diagnosis is dead-on. I added my lines property to the containing 
folder and it worked perfectly. I'm still mystified, though, as to why I 
couldn't put the lines property in another document in the same folder and 
use the notation 'doc_id.lines_id' to refer to the lines property in the 
other document.

Thanks, Steve

[Zope] Zope 'Best Practices'?

[Steve McMahon]

Is there anything like a Zope 'Best Practices' document or Wiki? One that 
would encourage use of certain practices, DTML idioms or products, and warn 
of practices, idioms or products that are known to cause problems down the 
line or are slated for extinction?

I ask this as a new user who's bewildered by the array of Zope tools and 
products. So, I read of a practice or Product and think 'wow, that's 
great!' But I have no idea whether it's in common usage and destined to 
become part of the core, or is headed for replacement or extinction.

Thanks! Steve McMahon

[Zope] ZMySQLDA, Problems Connecting

[Steve McMahon]

Greetings Zopers,

I'm attempting to make connections between Zope and MySQL using 
MySQL-python 0.3.0 and ZMySQLDA 2.01.

The Python/MySQLdb side is working. I can use "connect(db='test')" or 
"connect(db='test', user='guest', passwd='token')" -- where guest and token 
are a MySQL username and password -- to build a connection object and go on 
to do queries.

However, when I attempt to add a Z MySQL Database Connection to a folder, I 
get "Invalid connection string" -- no matter what the connection string I 
offer. (e.g., "test" or "test guest token" or "test@localhost guest token" 
or any number of permutations of these.

Anybody run into this problem? Any suggestions on avenues to pursue?

Thanks, Steve McMahon

 >...when I attempt to add a Z MySQL Database Connection to a folder, I get 
"Invalid connection string" -- no matter what the connection string

Problem solved. It turned out there was a line of commented-out diagnostics 
on the page that reported "Invalid connection string." That let me know the 
problem was an inability to connect through the socket. Checking that, I 
discovered that the RedHat default install has 0700 permissions for the 
directory containing the MySQL socket. Changing that to 0711 cleared up my 
problems.

[Zope] FTP Failures on new install

[Steve McMahon]

I've having trouble getting FTP working on a new Zope install. All other 
Zope functions appear normal, but I'm unable to transfer files _to_ Zope 
via FTP. I can use FTP to download files from the Zope server and can 
create new directories on the server. But attempts to transfer files to 
the server all result in "426 Error creating file" errors.



ftp> put test.html
200 PORT command successful.
150 Opening ASCII connection for test.html
426 Error creating file.


The problem is not a firewall problem; I can reproduce it with local ftp 
sessions and with no firewall in place.


I've tried several Zope versions from 2.6 to 2.7.7. All have the same 
problem. Common to the attempts is that they were all source builds with 
Python version 2.3.3 (#1, Mar 10 2004, 06:42:32) [GCC 3.3.2] on Solaris 
10 on a dual-Opteron Sun V20Z. I'd be happy to update the Python version 
if anyone thinks that might cure the problem.


Thanks! Steve McMahon

[Zope] Re: FTP Failures on new install

[Steve McMahon]

Sorry, I should have mentioned that there are no traces of the problem 
in the error log. Z2.log entries look routine, except for the ftp error 
itself.

Visit your "error_log" object (in Zope's "Root Folder" (ZMI!))
and see what it tells you about the problem...

Switching to python 2.4.1 cured the problem.

OK -- I get the picture I think ;-)

I will try to dodge the Solaris bullet if I can.


Just for the record, the conclusion of the cited report (once you read 
to the postscript 
) was:


"People really shouldn't be afraid of running python/zope on solaris,
especially in multi-cpu environments, as long as they understand how
python works, because you actually have much better resource control
than pretty well any other O/S out there, but as they say use the right
tool for the job, and make informed decisions ;-)"

Also, the concerns about Solaris were related to poor performance under 
Solaris 8 on a multi-Sparc platform. Anybody got any more recent 
information that might apply to Solaris 10 or to an Opteron platform?

[Zope] Windows Server 2003, II6 and ASP404 vs form posts

[Steve McMahon]

Anyone out there using Zope inside IIS 6 on Server 2003 via the ASP404 
technique?


I've done this successfully on Windows 200 and XP, but on Server 2003, 
IIS does not seem to be passing the post data to the error handler.


When Win2003 was young, there was some list traffic on a similar 
problem, and Brian Sullivan figured out that IIS was reporting a 
REQUEST_METHOD of "GET" even for POST requests. However, the POST data 
was still passing, so it was possible to check Request.totalBytes (this 
is the ASP Request, not Zope's) to determine the real nature of the request.


Now, though, many an IIS patch later, IIS is invoking the error handler 
with http content length set to zero (even though it reports that 
content type is www-urlencoded). So, form submissions do nothing.


And, if there's nothing to be done about this, does anyone know if the 
Fresh Logic or Enfold ISAPI solutions have any way to intermix serving 
of IIS and Zope content? If I didn't have to do that, I'd be using 
Apache, and be done by now ;) .


Thanks!

[Zope] Re: Windows Server 2003, II6 and ASP404 vs form posts

[Steve McMahon]

For anyone else who might search the list in the future:

Microsoft has confirmed that ASP error handlers in current versions of 
IIS 6 do not, can not, and will not -- no matter what the security 
settings --  get at POST data. There's a discussion of the changes at:


http://blogs.msdn.com/david.wang/archive/2005/11/29/Child_URL_Execution_and_SSI_exec.aspx

The author confirmed that the changes also affect custom error handlers.

So, the days of serving Zope pages on IIS via the 404handler.asp 
approach are pretty much over.
