Blank Date Field?
by James W. Howe 13 Jul '00

13 Jul '00

Is there some easy way to allow for the storage and display of an empty/blank date field? It seems that you are unable to enter a blank value if you defined a property field as storing a date value. I want to be able to store dates in my object, but the date value is optional. Any tips would be helpful. James W.

I want to update from Zope 2.1.6 to 2.2.0. Is there a way to copy my contents to the new version or do I have to start from the beginning ? Thanks Mario

Aaron, The has_role method of User objects can take an optional second argument, which is the object to use as context (to take local roles into account). Note also that you need to pass the list of roles in as sequence. The following should do what you expect: <dtml-if "AUTHENTICATED_USER.has_role(('Manager','siteManager'), this())"> ... </dtml-if> Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

ZCatalog Find Items from dtml
by Bob Barter 13 Jul '00

13 Jul '00

I would like to force a ZCatalog to update itself with something like: <dtml-call "myCatalog.manage_catalogFoundItems( ?????, 'objectType' )"> where objectType is the type of object that I want to put in the catalog. Looking at manage_catalogFoundItems in ZCatalog.py, I see the following parameters: def manage_catalogFoundItems(self, REQUEST, RESPONSE, URL2, URL1, obj_metatypes=None, obj_ids=None, obj_searchterm=None, obj_expr=None, obj_mtime=None, obj_mspec=None, obj_roles=None, obj_permission=None): >From the above, I am not sure how to construct the dtml-call. Thanks, Bob Barter

LocalFS Documentation

Hi, Anybody know where I can find out more about LocalFS, I've already read jfarr's How-to's and Product Information. But I still need more on how it works. Might aswell post up my problem since I'm already at it. Well, I have this dtml method that tries to add images:  <H2> </H2> <P> <dtml-with REQUEST> <dtml-call "REQUEST.set('userTABPIX1',REQUEST.form['userTABPIX1'])"> <dtml-call "manage_addImage('',userTABPIX1)"> </dtml-with>  Data Has Been Successfully Inserted!  I tried replacing (blindly) the <dtml-with REQUEST> tag with both <dtml-with myLocalFS1> and <dtml-in myLocalFS1>, and as to my expectations it did not work. How would I actually upload to the LocalFS object (myLocalFS1) I've created? Does anybody know how??? k.c.

testing for local roles
by Aaron Payne 13 Jul '00

13 Jul '00

Hi all, Is <dtml-if "AUTHENTICATED_USER.has_role('Manager','siteManager')"> .... </dtml-if> valid for local roles? siteManager is a local role. It seems that if I use this and there is a user with a local role present nothing is displayed. I'm wondering if there is a has_localrole(....) method of AUTH..._USER but I haven't been able to find it. -Aaron

The way to pass args to DTML methods is via a form post or via a link with a query string (or a form get). The publisher "eats up" the rest of the URL and returns a Not Found error if you try to tack on indiscriminate things after a method name. Sorry. Your option is to write a custom object that handles this via __bobo_traverse__. I'm still not sure why you can't just do: <a href="my/method?a=1">1</a> as opposed to: <a href="my/method/1">1</a> > > I don't really get what __bobo_traverse__ is or how it would help.

I would search the mail archives for __bobo_traverse__ if you want to know more. I'm not even sure if Zope exposes PATH_INFO in REQUEST. It might. I doubt it would help if it did, however.

For Newbies Only!

Ok folks if you are like me and not only can't see the light but can't even find the path to the light try these things: 1. Do the Python tutorial. 2. Read every message from the list archives for the past two months. 3. Even if you don't want to develop on a beta platform. Install 2.2b4 on another machine and go through the tutorial. Then read the API docs. Took me more or less two days. Time VERY well spent. Now go back to your application and yea shall see the path that will lead you from darkness. Just my two-cents on how I found the path... -- Tim -- Opportunity is missed by most people because it is dressed in overalls and looks like work. Thomas Edison

Re: [Zope] Customising the calling of the _add method for a product
by icottee＠bluefountain.com 13 Jul '00

13 Jul '00

Due to lack of response (wise people) I removed everything and started again. Of course the way that I previously thought it should work but didn't now works fine. Just used <dtml-var TimeSheet_Add> and all was fine. Hey ho --- Original Message I have a TimeSheet product which is currently utilising the suggestions from one of the howtos on zope.org, to make the handling of errors a little smarter. Subsequently my addForm code checks to see if any errors were detected and, if not, tries to go to the usual _add method. But this fails. The code below shows what I currently have. If I can just call this _add method I am finished. <dtml-if "I_Error==1"> <dtml-var TimeSheet_addForm_include> <dtml-else> <dtml-call "TimeSheet_add(_,_.None)"> </dtml-if> As always, any help greatfully received Ian

This is a job for __bobo_traverse__ (yes, I know, unlikely name, but what has now become Zope used to be named Bobo). Without using __bobo_traverse__, which is defined as a method on the object which you access via traversal, you can't easily use "extra" URL elements as parameters to pass to the object. An sample __bobo_traverse__ method: def __bobo_traverse__(self, REQUEST, name): """ 'name' here is the remainder of the URL """ return self._data[name] It might be easier in your case if you're not used to python to construct your own Zope objects in which you can place a __bobo_traverse__ method to just use query string arguments instead, which are available through the REQUEST object. > -----Original Message----- > From: Leichtman, David J [mailto:code@ou.edu] > Sent: Thursday, July 13, 2000 2:27 PM > To: 'zope(a)zope.org' > Subject: [Zope] (no subject) > > > I've previously been a Perl programmer.
