Here's an orthogonal proposal: create a separate list/group for Zope setup & installation issues. Regards, -Simon

Newbie: help with math syntax?
by David Robson 16 Sep '99

16 Sep '99

...in fact I�m not quite experienced enough to be a newbie. I�m trying to write a series of simple DTML Documents to learn syntax. I�ve read lots of Zope docs but haven�t found an example of add, subtract, multiply, divide. (Probably too simple.) Here�s my unsuccessful attempt in two DTML pages: Code for index_html  <h2></h2> <p> This is the  Document. <BLOCKQUOTE> <FORM ACTION="addTotal"> <P>Enter a number: <INPUT TYPE="text" SIZE="3" NAME="number1"></P> <P>Enter a number: <INPUT TYPE="text" SIZE="3" NAME="number2"></P> <P>Enter a number: <INPUT TYPE="text" SIZE="3" NAME="number3"></P> <INPUT TYPE="submit" VALUE="Compute"> </FORM> </p> </BLOCKQUOTE>  /\/\/\/\/\/\ The above DTML Document seems to work OK. It calls the DTML Document addTotal which reads back the parameters OK but won�t sum them�no doubt because I�m using the wrong syntax. Here�s code for addTotal including my unsuccessful guesses.  <h2></h2> <P>The first number is </P> <P>The second number is </P> <P>The third number is </P> The total is: ++<BR> Not!</P> <P>Perhaps the total is:             <BR><BR>Still not!<BR><BR>  /\/\/\/\ Can someone please write the correct sum expression for me? While you�re at it, how about the expression for finding the square root of one of the numbers?

If a database adapter sits around in memory unused long enough, Zope will deactivate it (store it to disk, remove it from memory), when it does this, the connection goes away. When the object is activated, it is re-connected. Idle timeout, on the other hand, should be a function of the server. It is DA specific whether or not the DA is smart enough to reconnect after being idle timed out by the server. -Michel

Maximum zope database size BUG on Solaris
by codelarvs＠ciudad.com.ar 16 Sep '99

16 Sep '99

I have Zope 2.0.0 binary distribution on a SPARC SunOS 5.7. My problem is that when the database grows up to 2gb and I try to keep adding files, Zope reports the folowing error: " Zope has encountered an error while publishing this resource. Error Type: OverflowError Error Value: integer addition " i've searched in the mailing list archives and fond that the problem may be because my operating system doesnt allow files over 2GB, but Solaris seems to allow them. Is this a Bug? Or I'm doing something wrong? If this is a limitation from my os, is there some way to suprpassit from zope? Thanks for reading!

Is it possible to set Zope to close an open ODBC connection once it has been idle for a specified period of time, then reopen the connection when traffic comes in that needs it? __________________________________________________________________ Jim Sanford ^ Database Engineer ^ ^ ^ Accelerated Technology, Inc. ^ ^ 720 Oak Circle Drive East ^ ^ ^ Mobile, AL 36609 ^ ^ ^ Voice: 334-661-5770 fax: 334-661-5788 ^ ^ E-Mail: jsanford(a)atinucleus.com Web: http://www.atinucleus.com Source Code, No Royalties, Any CPU...It just make sense ! __________________________________________________________________

RE: [ZDP] managing zope projects in a structured fashion

You can restrict who can add what object by Role. Thus, if a user is in a role that can only see 'Site X' they will only be able to add object (and only see those objects in the add folder) that they have permission to add. This is done with Permission objects. This compliments well with the security paradigm of Zope, where you compartmentalize users by role anyway. > the question is: is there any way to create a products-folder > as a subfolder > of a given project's base folder? or is there at least some > way to organize > products via subfolders of the common products-folder?

In this case, you probably want integers or floats. Instead of: NAME="number1", try NAME="number1:int" or NAME="number1:float" (you may want to put default values of zero in these fields as well). When the form is submitted, the value for 'number1' will be an integer or float object, which you can then do math on, like thus: The total is: <BR> For doing square roots, it _might_ be something like  Behold the power of the new www.zope.org site and the documentation and how-to's it contains, as well as the Zope Quick Reference. They'll have more information on this.
