I am not sure, what type of object is used at the base of "FileUpload" objects (to give them there file like behaviour). If this a "cStringIO" objects, they may have a "len" attribute. This means, you could use "your_uploaded_file.len" to get the length. Otherwise, you could try: file.seek(0,2) # positions at the end len= file.tell() # tells the current position (i.e. the length) file.seek(0,0) # positions at the start That's Python code. You can do something equivalent in several DTML commands. Dieter

sql query results -> DTML method problem
by Lee Reilly CS1997 16 Dec '00

16 Dec '00

Hi, I have a TINY problem, which I think there is a simple solution too... but for the life of me, I can't find it! I'd be grateful if someone could point me in the right direction. I have a database setup containing details of classes, students & lecturers. The user is prompted to enter a class code (a unique key) which is used to query the database and return the class title. Simple. A DTML method prompts me for the class code -- I enter 52.139 and it posts to a method 'enterClassCodeAction', below. #1 <dtml-var standard_html_header> #2 <h2>Confirm</h2> #3 <p>You entered <i><dtml-var class_code></i></p> #4 #5 <p> #6 Our records show that <dtml-var class_code> is called #7 #8 <dtml-in expr="findClassTitle(code=52.139)"> #9 <dtml-var title> #10 </dtml-in> #11 #12 #13 </p> #14 <dtml-var standard_html_footer> ^ The method works fine when the class code is manually inserted (line #8) but when I try to pass the variable from the previou post, held in <dtml-var class_code> I have probs. <dtml-in expr="findClassTitle(code=<dtml-var class_code>)"> *** syntax error findClassTitle is a ZSQL method for returning the class title given a class code: select title from classes where <dtml-sqltest code op=eq type=float> Hmm... anyone see the problem? Thanks a lot :) - Best regards, Lee

I\'d like to take the contents of a variable, and they being the name of an image object, render it on the web page as an IMG SRC, just like a <dtml-var image_id>. I know this could be done with external python scripts and eval. But so far all i get is integeroverflows. any ideas? please cc: me because I\'m a little bit busy.

LoginManager and SSL client authentication
by Mayers, Philip J 16 Dec '00

16 Dec '00

All, LoginManager is now working well... We've got a bespoke application for storing our (very large) user account database here. One field a user can have is a crypted unix password (which I'm currently using to authenticate users). The other thing that can exist is the Subject or SubjectAltName of an SSL certificate suitable for client web authentication. I'd like some users (who are *not* technically strong) to have access to the web frontend without having to type a password - they have had a visit from a member of staff to install a client certificate, and just "point and go". How would I go about making LoginManager authenticate them on the basis of the certificate subject? Apache will validate the certificate for me (by passing a valid CA cert to it's configuration) and I'm running over PCGI, so by the time we get into Zope, we can "TRUST" the SSL_CLIENT_S_DN and SSL_CLIENT_I_DN values passed in. What's the next step? Regards, Phil +----------------------------------+ | Phil Mayers, Network Support | | Centre for Computing Services | | Imperial College | +----------------------------------+

How to make two racks work under one specialist?
by Dirksen 16 Dec '00

16 Dec '00

I set up two racks in one specialist, one is maleMemberRack, the other femaleMemberRack. Both are loaded by accessing attribute id, and have skinscripts to retrieve data from a db. Suppose the femaleMemberRack gets loaded first, it finds out from the db that the 'id' is a male, then how can it pass the process to the maleMemberRack?

More on DB Transactions
by Paolo Quaglia 16 Dec '00

16 Dec '00

Reading the zope(a)zope.org archive I found one message with an interesting sentence: [Message] > I am currently considering and evaluating Zope as one of the options we have > to build a really large, completely databasedriven "enterprise scale" > web-platform. I am a bit worried about this "maximum of 7 threads per db This isn't a maximum. It's just the default. It's easy to increase the number of connections. [/Message] Where is this Default and How can I increase this counter?? Thanks very much in advance Paolo Quaglia Information Technology Coordinator Sitek S.p.A. paolo(a)sitek.it
