ZopeTime questions (DTML mainly)
by Samu Mielonen 15 Oct '99

15 Oct '99

Hello, I'm trying to figure out the ZopeTime object (or is it a method?) and how to use it. I've tried to render Finnish date and time, which is of format: dd.mm.yyyy, hh:mm:ss so for example: 15.10.1999m, 21:04:05 means 15th of October, 1999 at four past nine pm (and 5 seconds) Rendering this visible with <dtml-var ZopeTime fmt=...> seems straightforward enough (here, without seconds): <dtml-var release fmt="%d.%m.%Y, %H:%M"> but the problem is that %H (and %d, %m %Y too because of this?) are not from the current time zone (but from GMT?). This means that if I use the above code at 11 o'clock a.m. Finnish time, I get result that says time is 9 o'clock a.m. More than that, if I want a render the time of an object that had a release date (of Finnish time) at 01:59 am on the 1st of November 1999, the above code would show a release time of 11:59 pm 31st of October 1999 (?) However, if I use the format: <dtml-var ZopeTime fmt="h_24"> I get hours in 24-hour format in current time Zone (i.e. correct Finnish time). Rendering the time this way would require me to type: <dtml-var release fmt=day>.<dtml-var release fmt=month>.<dtml-var release fmt=year>, <dtml-var release fmt=h_24>:<dtml-var release fmt=%M> am I correct? It seems to work ok, although I haven't checked whether the "day" changes according to GMT or current time zone (if it changes according to GMT hours, then I'm in trouble. Same for "month" and "year"). However, a few of questions puzzle me: 1) Are day, month, year and h_24 synchronized whereas %d,%m,%Y,%H are synchronised differently? (i.e. one should not mix them in order to avoid funny date/times). 2) Why are the formats different? I couldnt find reason/documentation as to why one reports hours in current timezone and other in GMT. Or have I misunderstood something completelly? 3) Are the two options (using one dtml-var ZopeTime vs using multiple ones) equal in the load they put on Zope? I would assume that a simple dtml-var call would be less of a load, no? This may not sound like an important issue, but if the latter approach puts a five-fold increase on zope and I have to call that dtml method giving Finnish time, say 100 times on a page, well it might have an impact (?) 4) Can I somehow add the time zone difference to the time with simple add operation? i.e. can I use the <dtml-var release fmt="%d.%m.%Y, klo %H:%M"> format and somehow just tell that: "add +2 hours" to that time? I'm assuming there isn't an add operation for timestamp data types in dtml? If there is one, is it clever enough to understand that when hours are overflowed, it has to tick one more day and deduct appropriately from hours (the same for month and years of course)? How would I accomplish this (my apologies if a lot of my questions are about my inability to grok the syntax properly). 5) If I want to make a simple time comparison between release date property of an object and current time, how do I do it (e.g. if I only want to compare, say that the dates are same - not caring about years, months or hours and seconds). If my current object has a property release which has been set to ZopeTime at the time of creation: I've tried making an equality check between (i.e. the below pseudo code in gazillion variations): ZopeTime fmt=day = release fmt=day but "fmt" mucks up the syntax somehow (I don't know how to write the comparison when fmt=day is present). Without the fmt attribute: <dtml-if "ZopeTime=release"> worked fine (I think). So, how do I compare just parts (say days) of two timestamp properties? Do I need to create an external method? Again, any help is appreciated. The previous comments were right on spot. Much thanks to Michel Pelletier for taking time to answer my questions.

Future of Zope
by Ian Clarke 15 Oct '99

15 Oct '99

As a new Zope user I am very very impressed by the amount of work that has gone into this software. I must confess though that I find DTML a little cumbersome to use, and debugging is very difficult (I have yet to find a solution to the problem I described in my "Problems with <dtml-tree>" thread). Is there any prospect of some form of friendlier developer GUI to Zope, perhaps a Java client. Features such as Syntax highlighting of DTML, and a better error description system, would greatly enhance the ease of use of Zope. Further, such a system would not need to replace the present HTML interface, but could be used optionally. I may be showing my newbieness here, but I guess a good first step might be a Java conduit to the Zope database - perhaps one already exists. I am not knocking the hard work that developers have put into the system, however I suspect these are the questions that many Zope newbies will be asking.

Passing optional parameters to an Z SQL method.
by Morten W. Petersen 15 Oct '99

15 Oct '99

I've got an Z SQL method that has the arguments locatestring:string and created_after, created_before, lastmod_after, lastmod_before. Now, in the SQL method, I've got the usual stuff; SELECT bleh.id bleh.title FROM bleh WHERE LOCATE(,bleh.title)  AND bleh.created >  AND bleh.created <  AND bleh.lastmod >  AND bleh.lastmod <   This works perfectly when I perform the query through the test interface, however, it chokes when I use it from a DTML document, saying it can't find the created_* and lastmod_* variables in REQUEST. Any alternative ways to perform this? Also, are there som utilities for parsing *a lot* of Z SQL methods/DTML documents for strings, and then replacing them? -Thanks in advance -- ------------------------------------------------------------ "One World, One Web, One Program" - Microsoft Promotional Ad "Ein Volk, Ein Reich, Ein Fuhrer" - Adolf Hitler ------------------------------------------------------------

I don't get any error on the copy, but the paste says the clipboard is empty. Any suggestions on how to better/correctly do this?

Hi all, Sometime ago there was someone who was making snapshots of the zope source tree available to compile on win32. Anyone know what happened to this, or anyone have any idea about how to get zope compiled on win32 with VC++6. Digicool, how do you do it? Any chance of getting the project files etc. for VC6? TIA Phil phil(a)philh.org
