Creating Python class instances via DTML
by William M. Schmidt 27 Mar '00

27 Mar '00

Greetings, I have created a Python class (Lead) and added it as a product and am able to create and edit instances via the managment interface. However, I have run into a wall when trying to do so via DTML. Taking the path used in the "Adding ZClass Instances Programmatically" HOWTO, I've tried things like: <dtml-with "manage_addproduct(['Lead'])"> <dtml-call "manage_addLeadForm"> </dtml-with> where "manage_addLeadForm = HTMLFile('leadAdd', globals())" appears within ".../Products/Lead/Lead.py" and "leadAdd.dtml" contains the form used to populate the object fields. I continually get "NameError's" on "manage_addLeadForm" so I'm guessing that I'm have namespace issues. Can anyone point me in the right direction? Thanks, Bill ====================================================================== Bill Schmidt Information Foundation schmidt(a)ifopen.com

date property format
by julio dinis 27 Mar '00

27 Mar '00

Hello you all! I have a timestamp, for instance, 2000/03/27 19:57:53.9808 GMT. Lets say I have a document property, type date, where I want to store this timestamp. I found that the use of A or B is different: A) <dtml-call "REQUEST.set('Prop1', ZopeTime())"> <dtml-call "manage_changeProperties(REQUEST)"> B) <dtml-call "REQUEST.set('Prop1', ZopeTime())"> <form action=manage_changeProperties> <input type="text:date" name="mydate" value=<dtml-var Prop1> <input type=submit> </form> The difference arise when formating for presentation: A) Code : <dtml-var Prop1 fmt="%Y/%m/%d %H:%M"> Output : 2000/03/27 18:57 B) Code : <dtml-var Prop1 fmt="%Y/%m/%d %H:%M"> Output : 2000/03/27 19:57 Note: the 1 hour difference. I guess the difference is in the "Prop1:date" that forces zope to create the correct object with all the information needed to, for instance, recognize the GMT change since March 26. I found that using another kind of presentation format will bypass this problem, i.e, instead of fmt="c style", I use functions like dd(), mm(), timeminutes(). Is there a way to make the code A tell zope to create a correct date object(property)?

I don't think I'm following you - what do you mean by "it doesn't do authentication"? After setting up a Web Folder pointed to a folder in your Zope installation, what happens if you try to drag a file from your desktop to the Web Folder?

Same name property for different propertysheets
by Oscar Picasso 27 Mar '00

27 Mar '00

In the Z Class tutorial (page8) I read: "Property Sheets also allow more indirect access to properties via the propertysheets attribute. ... we could access the 'title' property via propertysheets.stuff.title attribute in addition to simply the title attribute. The sort of access is handy in the case where two different propety sheets define properties with the same name." Sounds great, so I tried to use to it to create a sort of "international" class: myClass: propertysheets english name description ..... but if i try: myClass: propertysheets french name ..... i get the following werror message: Invalid property id, first_name. It is in use. So it seems that contrary to what suggests the Z Class tutorial it is not possible to have two properties with the same name in the same ZClass even if they are in different propertysheets at least when using the management tabs to add a new property. Is it a mistake in the tutorial or is there another means to add a property with a same name in another propertysheet without getting an error?

Hi guys - Have you sent anything about this to support(a)digicool.com? If not, please do send a report that describes your environment and how to reproduce the problem. Stability problems are a high priority for us, and if we have an easily reproducable one here, I'd really like Michel to look into it if he hasn't already... Thanks!

webDAV and IE 5.0
by Satheesh Babu 27 Mar '00

Hi, I've Zope 2.1.4 running on NT4.0, using ZServer. I would like to set up IE5.0's "Web Folder" feature for Zope, with Zope's authentication. I could set up a web folder, but it doesn't do authentication, so I can't've any PUT rights... Any thoughts?

I had difficulties compiling the ZMysqlDA with egcs on my Redhat 6.0 and 6.1 respectivly Mandrake 6.1 and 7.0. A friend of mine compiled a version for me with an old version of gcc and that worked well for me. If you like to, I'll send you the compiled version, just ask... Andy Pahne ap(a)net22.net

I can probably figure out how to make sure libpq (postgresql API library) is reentrant (it might be already). What has to happen to the DA to make this work? And if this was done, could you configure the DA to open, say 5 backend processes and use them in turn? -- cary
