Squishdot Post Time-Shifting Code - For Posterity
by complaw＠hal-pc.org 13 May '02

13 May '02

This is for posterity. I hope someone can use it in the future and save themselves a little time. The Problem: Your Zope site (and, but extension your Squishdot site) are in a server in one time zone, and your users are in another time zone. Your users are annoyed when their postings seem to be seven hours off. While you are happy that they notice such things, they pepper you with emails and postings to the effect that something is wrong, when in fact, all is right. To stop receiving the "bug" notices, you need some code to "time shift" the time displayed by Squishdot from your user's time zone. The Solution: In the index_html and posting_html DTML Methods in the Squishdot site, replace... <dtml-var date_posted> with... <dtml-let my_zone=date> <dtml-var "my_zone-0.2916667" fmt="%A %B %d, %Y at %I:%M %p"> </dtml-let> .. where, in the case above, 0.2916667 is the time shift (7/24) to move from the Netherlands to CST. Substitute the value above for your time shift. The posting object has a "date" method that retuns a DateTime that you can use to perform the arithmatic. Many thanks to Chris Withers for his astounding patience. Hope that helps. Ron

Hi, - Why are you sending this to me? I'm not the one who has a problem. - Please don't send HTML mails. - Please keep the subject so that we can find the thread you're responding to. - Your first method isn't always applicable, it's not always possible to split the form in two. - Your second method doesn't work.

framed menu refresh?!?
by Mark A. Robinson 13 May '02

13 May '02

Hi all. Ok I have 2 frames in my app. Left frame is my tree'd menu with some status info, too. Right frame is my data input side. User navigates with left frame, and it anchors the appropriate page over in the right frame. Now, here's the problem: if on the right the user selects something that affects the status of the app, how can I refresh the left frame so that it will display the change in status? Thanks for any help!

making product from the filesystem
by Sylvain Thénault 13 May '02

13 May '02

hello, I'm attempting to make my first Zope product but I have some problems to install it to test it behavior. I've just put my code under the /usr/lib/zope/lib/python/Products directory, but Zope doesn't load my product. Is there anything else to do ? (there is a __init__.py which initialize the product, I took MailHost as example to construct my product) In a more general way, I don't understand how to reinstall a product which has been removed from the Zope www control panel... Does the products live in the ZODB ? Is there any problems with installing a product in Zope for testing (code may change directly in the filesystem) ? I didn't found consistent information about how to construct Zope products from the SF instead of from the www interface, and I'ld be able to read a document which answer to all those questions :-) cheers -- Sylvain Thénault

Even better, replace... <dtml-var date_posted> ..with... <dtml-var "date()-0.2916667" fmt="%A %B %d, %Y at %I:%M %p"> ..which is cleaner all around. Ron

Cannot copy/paste/rename zClasses
by Max M 13 May '02

13 May '02

Hmmm ... I have changed the meta type on a few of my zClass based products. I have also changed the "Add list name" in the factory, but I still cannot copy, move, rename etc. Has anybody got a clue?? Zope 2.5.1 but has been upgraded several times from way back. If I don't find a solution I will probably have to refactor into Python Products :-( and I could use that time for something else ... regards Max M

Hi, This was the only way I was able to get this to work. <form action="http://proton-80556:8080/intranet/input_test/manage_test" method="get"> input_test is the zsql. I tried this method <form name="form1" method="post" action="input_test"> but this is where the next thing I see is this zsql method in test mode.

How are you calling the zsql method that inserts the data? It sounds like you may be trying to pass the form variables directly to the zsql method (which isn't the best way to do it). Does your forms' "action" variable reference a ZSQL method? Jon

problem on delete off a ZObjectManager
by dorian santner 13 May '02

13 May '02

I have an object to delete (id=Santner.Dorian) and try to call a method (EPerson_delete) that is defined in the ZClass (EPerson) which simply does: <dtml-call "manage_delObjects(id)"> <dtml-if DestinationURL> <dtml-call "RESPONSE.redirect(DestinationURL+'/index_html')"> <dtml-else> <dtml-call "RESPONSE.redirect(URL1+'/index_html')"> </dtml-if> So I call http://myDomain/Test/Santner.Dorian/EPerson_delete >Error Type: BadRequest >Error Value: Santner.Dorian does not exist but it exists! Looks like Zope doesnot find the Santner.Dorian Object Funny is, that the upper method works with a simple ZClass, but does not, if the BaseClass is an ZObjectManager ! the ZClass - which does not work - extends the BaseClass ZObjectManager. So it has BaseClasses : ZObject, CatalogAwareBase, ZObjectManager (and it has several other Objects in it) while the other ZClass (where the upper method works fine ) only has: ZObject, CatalogAwareBase how to delete an ZObjectManager ?

Passing parameters into SQL methods
by Dennis Allison 13 May '02

13 May '02

I have a DTML method C which is called from another DTML method B, itself called from a DTML method A. I set a variable, call it X, in the namespace of A with a <dtml-let, and another variable, call it Y, is set with a <dtml-let in B. Both are visible in C (Thanks for the help there, Dieter...) The body of C is a <dtml-in that references the SQL method and then, in the form's body, renders the returned rows in an apropriate fashion. The query itself is paramterized by X and Y, the parameters appearing in the query in <dtml-sqltest tags. The query works from the test framework. >From the diagonstic reports I get when I publish the page, the parameter values set in methods B and A do not appear to be available in the SQL query even though they are available in C's namespace. (In formulating the query method, the name X and Y appear as parameters.) -dra
