Storing files or fileobjects in Session
by Peter Bengtsson 11 Sep '01

11 Sep '01

I want to store files (from HTTP FileToUpload) or file objects in a Session object. It's for a wizard thing. No sessioning products can store files or object as far as I know, but they can save references to them and that way simulate it as if you're storing objects in the session. Is there anything prepared like this that will save me time? If not, I'll write something that saves files as objects and stores the id in a session and then I'll sniff the id again to see if it can return the real object. Peter

Performance Problem Win2K
by Frank Stephan 11 Sep '01

11 Sep '01

Hi, I used Zope 2.4.1 on Win2K Server machine (P III 800, 512 MB). Just after the install it was running really fast when I used it locally. But after working a while (installed some products, made my own ZClasses,...) I had the problem, that now and then I had to wait about 10 sec for Zope to respond to a page request in management interface. Now that I changed to 2.3.3 for testing this behaviuor seems to be gone. Did any one have the same problem? How can fix it? TIA Frank

Does DreamWeaver 3 have WebDAV support? >No. And to use the Dreamweaver 4 WebDAV support you need a patch (which i didn't try).

Your Help is seriously needed : retrieving Dtml Documents with user input filled from the form
by Hamzat kamal 11 Sep '01

11 Sep '01

Dear Zoptistals, (I am very sorry for the inconveniences that might have caused then i seriously need your assistance) I am having one serious problem which I will like you to assist me. I am keeping archives which is reference by the users by typing the file name into a form displayed on the web. i stored the user input into a var name called date_code. <input type="text" name="date_code">. The action on this form is pointed to a folder that contain an index_html file, which reference the file that bear the actual name stored inside the variable date_code. <dtml-var expr="_.getitem(_.string.lower(date_code),1)"> to render the file. This work perfectly when a user type in the value for the date_code var. My problem is this. I have some other links on the index_html page which suppose to use the date_code value which the user typed to display their contents as well, and i have already stored those content in their various folders, but to my surprise when clicked on these links this is the error message i got: Error Type: NameError Error Value: date_code despite the fact that i set the path to those folder that contain the files. Please i need your assistance as soon as posssble. This is the url of the site :http://www.champion-newspapers.com On the home page clicked on archive button, when a newpage is displayed ignore the instruction and press logon button . Another page will be displayed asking you to enter the date code, for the purpose of this test type friday_1008_html and click view button. This will display the teaser archive for the news item, there after try to click on editorial on the left navi you will then see the error, despite the fact that i have the copy of friday_1008_html in the editorial folder. My impression is that since i have been able to use the date_code to display the teaser for the news item, then i should be able to use for all other link items on this page. thanks for your care.

ZPT WebDAV Editing Question
by Chris Withers 11 Sep '01

11 Sep '01

Hi, If I edit a ZPT over WebDAV using DreamWeaver (via Webdrive), I get a file object when I save 'cos DW's save process goes: 1. save temp file 2. delete original file. 3. rename temp file to new file. Has anyone found a way to get around this? cheers, Chris

Znolk
by Francois Meehan 10 Sep '01

10 Sep '01

Hi all, I have installed znolk on my zope site (and have mysql setup also), not being fluent with DB, I have problems setting up that product. If I use the znolk wizard (I just use 1 table) without any special options, it works no problem. But when I want to setup a "multiselect" select field with a drop down, I can't find the proper settings in the extended info. All I want is to be able to have 3 choices for the entry of a field. No lookup to another table. How can that be done? do you have a concrete example, I could not make use of the supplied instructions. Regards, Francois

You are doing difficult stuff, too difficult to be described in a book for starters.... You should keep in mind that a DTML method only knows what is explicitly passed into it. The above passes essentially "_", the current namespace. But this does not contain your ZInstance. You have two options: <dtml-with expr="_.random.choice(objectValues('myZclass'))"> <dtml-var myZclassDTMLmethod> </dtml-with> This pushes your ZInstance onto the DTML namespace and thereby makes it avaiable in your "myZclassDTMLmethod". or <dtml-let zi="_.random.choice(objectValues('myZclass'))"> <dtml-var expr="zi.myZclassDTMLmethod(zi,_)"> </dtml-let> This way, you pass in the context as "client" argument.

What's up with netcraft?
by David Lutz 10 Sep '01

10 Sep '01

I noticed that the latest netcraft survey shows that there are 4056 live Zope servers on the net in August. http://www.netcraft.com/Survey/Reports/0108/ This is down from 11756 servers in July. Here is a graph: http://www.ozzope.org/aboutzope/ What is going on here? Did half the people running Zope suddenly switch off their servers or did Netcraft muck up their stats last month? Cheers, David.
