Hi RDM 

Thanks! That works perfectly, and teaches me about namespaces. 
I just had to fix '' (I also do that)::

Since anything in any of the REQUEST dictionaries is on the name space
stack, you should be able to reduce the above IF block to:


  

  

  
  


If the 'cookie' dictionary is "closer" than the 'form' dictionary in the
namespace stack you'd need to stick one more REQUEST.set in the
inner if.

Obviously, I haven't tested this :)

RE: [Zope] Where do I find out about cookies?

2000-08-25 Thread Jean Jordaan 

Hi Loren, J. Atwood, Maik

Thanks for all the info! I'll digest & give feedback 
where I can. In the meantime, this is what I've fixed up
for myself (with a LOT of help from Roche Compaan) ..

In DTML Document 'index_html'::

 

In DTML Method 'docsSorted'::














   Title
  Origin
  Series
 




  
 

[Edit]

  

 


  
[... and so on for the other possibilities ...]

The rationale is:

'docsSorted' is called as method by 'index_html'. 
- Upon the first iteration, there is no cookie and no form
variable. A cookie and a form variable is set to 'title' as
default. The form variable governs.
- Upon subsequent iterations, if there is a form variable,
then 'index_html' was called from 'docsSorted' and the
sort-order has *just* changed. The cookie is changed (which
will not be noticed during this iteration since it first has
to be received again) and the form variable governs.
- If there is a only a cookie and no form variable, it
governs.

Now I want to extend it so that choosing a sort-order for the
*second* time reverses the order -- does this really entail 
repeating the entire '' section
for '"order=='reverse'"'?

I think I'm probably better off using the catalog for this,
rather than dtml-in batching ..

I am collecting everything on cookies in the developers portal
of the ZDP:

http://zdp.zope.org/portals/developers/sessionmanagement/cookies

Hope this helps. Once you have done more research, maybe you can
give some feedback, so I can add it to the ZDP ?

Best regards,

First you must understand cookies independent of Zope:

http://home.netscape.com/newsref/std/cookie_spec.html

Then Zope's interface to them will be easier to understand:

Search for "cookie" a little further in
http://www.zope.org/Members/ZQR/zqr/normal and you will find not only
REQUEST.cookies but also RESPONSE.setCookie().

[Zope] Where do I find out about cookies?

2000-08-24 Thread Jean Jordaan 

Hi Zopers

It looks like I'm going to be using cookies now, and I don't find any
How-To on cookies. What's the most instructive place to look? "UTSL" is
fine as an answer, especially if it points me somewhere, and even more
if it's DTML source .. 

The *ZQR* is a bit too cryptic for me. The *DTML Ref* has a bit more::

8. Dictionaries are objects that support looking of data by name 
(e.g. REQUEST.cookies['CUST_ID'] to look up a cookie named CUST_ID).
Dictionaries have has_key methods for checking whether a dictionary
contains a value (e.g. REQUEST.cookies.has_key('CUST_ID') ) and
methods keys , values , and items , for updating lists of dictionary
keys, values, and key-value pairs (e.g. REQUEST.cookies.keys() to
obtain a list of cookie names).

.. but I don't understand yet how 'keys', 'values' and 'items' are going
to help me *update* the lists -- it seems to refer only to querying
them, AFAICS ..
