[Zope] manage_pasteObjects question

[Palermo, Tom]

Hi David,
 
I reviewed OFS.CopySupport.py which is how I knew that eInvalid exception is
being raised. I also called manage_cutObjects with the REQUEST as you
mention. That's what is weird about this whole thing. I know that I had
clipboard data and the __cp cookie is set. Everytime I tried to do the
paste, I'd get the "cookie truncated" message. You're right about the
documentation. As with most Zope documentation, it's not that great. Lately,
I go straight to the source. I find I learn more that way.
 
Thanks,
Tom

Hi David,
 
In my last post, I wrote that I tried calling manage_pasteObjects a variety
of ways:
context.manage_pasteObjects(context.REQUEST)
context.manage_pasteObjects(context.cb_dataItems()) 
 
as well as the original:
context.manage_pasteObjects(cb_copy_data=context.cb_dataItems(),REQUEST=req[
'__cp'])
 
All 3 of these attemps results in the eInvalid exception gettting raised by
manage_pasteObjects( ). req['__cp'] is a reference to the cookie that gets
set when you place something on the clipboard. I was trying to grab a
specific piece of the REQUEST instead of the whole thing. Does
context.manage_pasteObjects(context.REQUEST) need to be written as:
context.manage_pasteObjects(REQUEST=context.REQUEST)?
 
It's kind of a moot point now anyway. I'm using some SESSION variables now
to store the ids of te objects I want to cut and the path of their container
so I can do the cut and paste from a single script. Not sure if this is good
or not but it's working for me now. It's one of those times when I just need
something to work.

Hi Tom,

I'm glad you found 'another way' but in the interest of no one I wish to add
the following.

These methods:  manage_copyObjects, manage_cutObjects and
manage_pasteObjects should be reviewed in /OFS/CopySupport.py - because the
current docs do not describe them well.

For example, the copy method works differently depending on whether you just
pass the container's Ids or pass the Ids *and* the REQUEST.

No reason to beat a dead horse  but of the 3 tries you listed only the first
can (but conditionally) work:

context.manage_pasteObjects(context.REQUEST) 

But *only* if you first called manage_copyObjects (or manage_cutObject) with
the REQUEST as a parameter included .... (only then does REQUEST get the
__cp object)

Your second try:

context.manage_pasteObjects(context.cb_dataItems())

Is wrong because it is passing a list of items in the clip board instead of
the the encoded copy object (returned by manage_copyObjects) that
"manage_pasteObjects" expects

Your last try is wrong because both parameters are incorrect. :-)

All best,

David
