Re: [Zope] Presentations Available
Thanks Bill, I saw that in a few google hits but ... I figured that if a fair population wants to view the presentations then the files should be in a universal format - like pdf or rtf. Its an interesting question: how many people who just wish to peruse the files will feel compelled to google and download new apps just to be able to read them?

Re: [Zope] SQL query in ZSQLMethod
How do you want to change this notation? What is it you want to do?
Please spend as much time writing a question as someone may in
answering it!
You do not want logic in your zsql methods.
I tend to use python scripts for branching logic, eg
# python script
request = context.REQUEST
if request.get('value1') == someValue:
do the add zsql
else:
do the edit zsql.

[Zope] Pluggable Brains
Hi Zope, I've been using pluggable brains in some zSQL classes. I have some questions! a) It seems if I initialize a variable in the __init__ method that variable, say self.callCount = 1 is not retained across calls, eg #python mod res = context.sql.brainySQL() for rec in res: rec.getCallCount() # where getCallCount is a method inside the Brains class and it just returns the var defined in __init__. But I get an attribute error instead. b) Can anyone direct me to a good faq on using these things? c) Has anyone experience with Pluggable Brains and zSQL? I am especially interest in performance issues because I intend to use Pluggable Brains to do *alot* of calculations - but only if the upside beats the downside of using them. d) Will Zope 3 support Pluggable Brains?

Thanks for the reactions. It works! My current code looks like this now:

Of course, it is stupid to make getPhysicalRoot private
when it is so easy to access the root anyway...
Why not just add 'root' to the script vocabulary?
If I recall, Casey Duncan suggested putting a python script in *root*
named ROOT, e.g.
#module ROOT
return container
This is aquirable from anywhere else in Zope and is easy to remember.

[Zope] numeric formatting
Hi List, I will have to format numbers based on country and currency types. I understand the locale module can do this. I've done some googling on this but cant seem to get anything definitive. I've read that the local module is not thread-safe but I do not know how this would impact my Zope app. I do know that I would want to be able to change from one currency format to another depending on which currency conversation the user may want. Really my question is, what approach is recommended for a Zope application to format numbers according to currency type?

Re: [Zope] TAL and Javascript
Rob,
As others have pointed out the approach you indicate will not work.
To summarize -
Write python script to dynamically create JAVASCRIPT code (you can
format javascript arrays of data from your db this way).
Then, using TAL load it in, eg
head
tal:js replace=structure
here/python/pythonThatCreatedJavaScriptjavascript here/tal:js
/head
Which is then callable from the other javascript routines in your page.

I'm stuck this, and would appreciate help or pointers.
I have a form with 2 selection drop-downs. I want the user's choice of

But: I cannot get the Javascript var into the namespace that the TALES

var choice = widget.options[widget.selectedIndex].value;
var data = [result of calling Python script 'foo(arg)' with

// create options for select 2
}
/script
[various html...]
select id=select1 onChange=makeDropDown()
[options...]
/select
I've tried with multiple scripts, where one has tal:content=... but
cannot figure out how the TALES expression can get at what my

inside Page Templates, so perhaps I'm going about this all wrong.

Re: [Zope] merging the contents of two acl_users folders
Jim,
Alright, I found the way to get needed user information in order to
merge (create users in a dest folder).
You need an external script. Otherwise you will not be able to access
acl_users _getPassword(). Local scripts enforce this for security
reasons.
So here is the external script that you can modify to your needs
#
#Zope/Extensions/getUserData.py
# just pass in the *source* acl_users folder
#
def getUserData(self,acl_users):
users = acl_users.getUsers()
dict = {}
for user in users:
dict[user.getId()] = {'name' : user.getUserName(), 'password' :
user._getPassword(), 'roles' : user.getRoles() }
return dict
Then call this with a local python script:
request = context.REQUEST
users = container.getPasswords(acl_users)
for k in users:
user = users[k]
print k,user['password'],user['name'],user['roles'] # to test
Hope this helps you reach the "tipping point" if you've not already
gotten there.

Thats the first example of that logic I've seen Mixing CSS

When body lang="de" then
body.de #rightcolumn h1 { ...i/news_title_de.jpg ... }
Kicks in.

It's working like IN over a string, e.g. the [5,61] will make selected
the number 5,6 and 61.
dtml-call "REQUEST.set('ids_test', '(' + id_test[1:-1] + ')')"
Where id_test is the result of the database query wich return in this
format: {1,2,3}. I modify it to a (1,2,3) and finally I try the
dtml-call "REQUEST.set('list', _.list(ids_test))"
Following this api:
list (sequence)
Return a list whose items are the same and in the same order as
sequence's items. If sequence is already a list, a copy is made and
returned, similar to sequence[:]. For instance, list('abc') returns
returns ['a', 'b', 'c'] and list( (1, 2, 3) ) returns [1, 2, 3].
I need a integer-list, is it possible?
Fernando,
I'm rusty with DTML But I know you can get a list returned using
_.string.split(idstest,',')
But Id call a python script with idstest as a param, eg
dtml-call "REQUEST.set('myList',pyMakeList( idstest ))"
Eg,
python
import string
idstest = '{1,2,3}' # test only is param
s = s[1:-1]
list = string.split(s,',')
return list
Good luck!

(2) dtml-call RESPONSE.redirect('index_html')

.
On #1 line I check if form variable is defined (it's defined in form, so if the form is
opened for the first time, the form is naturally null, and if the form is submitted -
it's defined to 1 [input type=hidden name=form value=1] ). #2 line let's skip for
a moment. On #3 line I do database actions with result checking. (On a wider scope - the
form is for user properties management - name, surname, address, login, phone, notes
etc.).
The problem is on line #2. According to what's written, zope should drop
everything and do immediate redirect to page index_html (ok, it's not where the
first error appeared, I just managed to generate this error as the most
clearest and best visible one), but instead zope calmly executes database
actions and does other stuff till the end of the document.
Id be very thankful for any ideas... it's sad not to control own code :/
If you want, I can send you the whole code as well as to provide access to the
live system.

exact version now).

You're trying to force your ideas of bookmarking and history management to the users. I wish I could impose my ideas on users. I respond to specs. Yes, I will fight the good fight when a spec is silly. I've even turned down gigs because the client was stubborn and what they wanted would be a disaster. But URL "cloaking" is not silly to some clients and the pattern I described handles it nicely and has benefits well beyond maintaining a stable URL.

That's it right there! Before 5.0.3, they were unpacked, meaning
saved like a char. Now they are packed, fixed point numbers. This is
screwing up the python functions for fmt.
Well, I was trying to NOT redo all that code, but looks like I will
have to if I want to run the new mysql. I have tons of reports using
dtml and fmt. I think I'll stick with 5.0.0 for now until I have
time for that. (spent it all trying to figure out where my problem
was!)
Though, I might just switch to Firebird if I have to do some code
changing on my app anyway. It's a bit more mature than Mysql's new
stuff. (considering it's still in beta) Mysql is just so easy.

So, I dont know where to go next. I can post this info on the mysql

using a fmt option on Zope.

DA) and there is no issue.
-- I can use Zope 2.7.3 with Mysql 5.0.0 on Linux (Zmysqlda 2.0.9b3,

-- When using Zope 2.7.3 with same setup as before, but with Mysql
5.0.4, problem exists.
-- Zope 2.7.6 has same issue.
I tried doing a simple dtml:
dtml-call REQUEST.set('dec',10.23)
dtml-var decbr
dtml-var dec fmt=dollars-and-centsbr
This works just fine. But when pulling 'dec' from Mysql, dtml wont
render it if using fmt.
I dont have to use Mysql 5.x. It's just that I already have the app
running on it, and I'd like to start testing the stored procedures and
other useful features.
Sorry for the long post. I just want to give as much info as
possible. Thank you for any help!

I guess one of my main questions too is, would Zope be getting

Hostile is an excellent word for that kind of behavior. It certainly breaks quite a few rules in the user friendliness book. So what exactly is the goal for following such a user-defeating technique? jens If I might disagree, keeping a stable URL is not, by itself, user-defeating. For example, user's do not like browser history clutter with subfolders and objects - all from the same application. Also, we do not want a user to open browser history and click www.myApp.com/updateChartOfAccounts. Because that would be out of context. Sure you can respond with an error message. But why should they see it in the first place? With a stable URL they just click www.myApp.com and they get the main page - every time. The question remains - is there an elegant solution to this. I think there is. Maybe 3 years ago Jim Penny wrote a message (I wish I could find it now!) regarding a web technique which I believe he referred to as the stateless machine. I liked the idea and have used it ever since. The idea is to use index_html as a request dispatcher. index_html simply responds to page requests and pulls in zpt macros, dtml and python code displaying to screen. An example: index_html request = context.REQUEST if request[caller] == 'Budgeting': if request[action_type] == 'Process': context.SQL.updateBudget() context.ZPT.showUpdatePage(context,request) and the caller looks like ... Zpt module Budgeting .. form name=budgeting action=index_html input type=hidden name=caller value=Budgeting input type=hidden name=action_type value= see with javascript input type button name=process value= Process onclick=Process() etc I believe that this technique is not only useful in the stable URL way, but it is very useful for larger applications - index_html becomes the engine driving the whole application. This centralizes a big chunk of application logic in one place.

Andrew Milton wrote: I think people on this list need to realize that eventually, the direction of any significantly large Open Source project is hijacked by the relatively small number of people actually doing the work. The reasons for this are many-fold, but, normally come down to a lack of communication between the developers and the users, which is realized in a lack of understanding by the developers of what the users want. This for the most part isn't generally a problem, until, the developers start to do things for the user's own good, like remove features that are kludgey, or a hack, or insert some other reason, which generally means either noone wants to work on it, or some other change caused it to break, and noone wants to fix it. Now to the credit of the Zope guys, they actually poll the users to find out, rather than just announce the demise of something. However, in general once you add a feature, you can be guaranteed, that somewhere, someone is using it, so removing it will always cause a problem. So there will always be an uproar when you poll. You're never going to be able to reduce the feature set between point releases without upsetting some group of people.

[Zope] Multiple Browser Id Managers question

Any thought ideas on this? Does the principal still stand, e.g. Not good to put a browser id manager in a place that can also acquire another browser id manager?

[Zope] SESSION invalidate method
Hi List,
I am curious about the SESSION.invalidate() method.
This code sets a SESSION key and value and then calls SESSION.invalidate():
tal:block define=dummy
python:request.SESSION.set('Dodgers','Baseball') /
p before invalidate /p
p tal:content=python: request.SESSION /
tal:block define=dummy python:request.SESSION.invalidate() /
p after invalidate()/p
p tal:content=python: request.SESSION /
Produces this output:
before invalidate
id: 11125588150079827980, token: 95966850A1xaz-gQYlU, contents:
[('Dodgers', 'Baseball')]
after invalidate()
id: 11125588150079827980, token: 95966850A1xaz-gQYlU, contents:
[('Dodgers', 'Baseball')]
It seems that SESSION.invalidate() does not take immediate effect.
Seems like a developer could getinto trouble if the same script *both* does
SESSION.invalidate()
SESSION.set('something','somevalue').
Because after the script runs 'something' goes away when invalidate()
finally
occurs.
And is the effect described above to be expected or do I have this wrong?
Thanks,
David

Sune,
Thats great! Thanks.
My tests confirm this excerpt from Collectors/Zope/1594: 'The suggestion
... to use context.session_data_manager.getSessionData() to get the
session after the call to invalidate works - it gives me a new session
object, and all is well :)'
