RE: [Zope] [ZClass constructor question]: How can I copy objects into my container class?

22 Nov 2001

      Hi Jim,
Nice one! I went with the script approach and called from within the:
 <dtml-with productname.createInObjectManager(REQUEST['id'], ...)>

All worked fine. Thank you.

I looked at the other approaches you mentioned:

<dtml-with newitemname>
...
</dtml-with>

&
<dtml-call "newitemname.init()"> 

Much headscratching.

What do I replace 'newitemname' with to get it to work? I tried
"REQUEST['id'].init()" and several variants but get "Attribute errors"
about "init".

The only way I can get stuf fto work is when the init() call is made
inside the "<dtml-with productname.createInObjectManager(REQUEST['id'],
...)>" block.

I guess I need help figuring out how to look-up the name of the item
that's contained in the var 'id' and use it as part of the call.

Thanks again,
Simon.

	Hi, Simon

	The standard answer is to use the dtml-with tag:

	<dtml-with newitemname>
	<dtml-call "manage_addBlah(params)">
	</dtml-with>

	But you might consider making a python script called "init" or
something
	like that for the class you are adding:

	methodID = 'example'
	methodTitle = 'This is the example method"
	methodStandardText = """<standard_html_header>
	            example dtml text goes here
	            <dtml-var standard_html_footer>"""
	container.manage_addDTMLMethod(id=methodID,title="")
	container[methodID].manage_edit(data=methodStandardText,
title=methodTitle)

	then after you add the new item,

	<dtml-call "newitemname.init()">

	hth,
