I recommend to use english in the code and use german as a translated language. I'm not really sure if we should support german Umlauts at the python leven and take care for encoding. I guess this is what translation should be used for. Or not? Hi Roger, OK, let me put it this way: If I really have to use i18n for those umlauts on buttons (and that's what I might have to do if nothing changes) then you might be right in that it may be better to use English as the default language and German as one of the languages looked up by i18n, i. e. to use: @button.buttonAndHandler(_(u'Change')) and have i18n find Ändern as the German translation for Change. At least I guess this is what gettext docs would suggest. The other way around might not even be possible due to some gettext restriction - not sure about that. However, this particular app of mine will never be an international app, it will always be German only. It is just a simple app for a customer of mine here in Berlin, that's it, I just don't plan to make it a sophisticated multilanguage app. No need to negoatiate the languages accepted by the browser etc. - And till now, as long as I was using formlib, it was a simple app: as I pointed out, I could use something like this in formlib: actions[u'actions.aendern'].label=u'Ändern' It just feels awkward to make it more complex then was neccessary in the past. Besides, I can use umlauts in page templates without i18n - as utf-8 is the default there, just not on the buttons, this seems an assymetry to me. Also I specified the coding of my python file # -*- coding: utf-8 -*- which in py3k will be the default anyway, and buttonAndHandler() in z3c.form expects an unicode param, i. e. u'...', not just a plain string '...', doesn't it make sense to allow umlauts here - if ascii only is accepted then a plain string would have done it just as well. -Andreas ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] z3c.form, german umlauts on buttons

non-ascii chars for that matter) on buttons, for example (Ändern
- with A umlaut - ist german for Change):
# -*- coding: utf-8 -*-

Two points to note:

@button.buttonAndHandler(_(u'Change'))
My app is german only and if I was to introduce i18n I would still
make german the primary language and English the second,

Re: [Zope3-Users] Still trying am to build an EditForm
Hi Florian, I have been playing with your example, try this: download http://user.cs.tu-berlin.de/~reuleaux/blogs.tgz unpack and cd into blogs edit buildout.cfg as you see fit: especially the eggs-directory should be changed, right now: /home/reuleaux/z3eggs $ python bootstrap.py $ ./bin/buildout $ ./bin/instance start|stop|restart|debug then goto: localhost:8080 you can e. g. add a folder there, say foo (but you don't have to) the use the My skin: http://localhost:8080/++skin++My/foo there you can add blog entries, edit them, see the list of all entries, there is some navigation bar on the left. Basically this is a mixture of * the addressbook-example of formdemo * your interface defs * Baiju's blog for zc.buildout example * some of my own stuff, that I learnt from z3c.form so far some points to note: * somewhere in a template I was having difficulties with widget/content - therefore changed to cntnt * there are some Makefiles in there that allow you to clean up - in the current folder with: make clean - recursively with: make rclean * the example really needs some cleanup - lot's of pkgs not needed - forms could certainly be used smarter: e g.

[Zope3-Users] z3c.form, checkboxes for Bool fields
In my interface I have Bool fields, say e. g. for invitation class IAdr(Interface) ... invitation = Bool( title=u'Invitation', description=u'Invitation?', required=False ) ... Now when rendering the following edit-form class AdrEditForm(form.EditForm): fields = field.Fields(IAdr) ... I get radio-boxes for invitation like so: (*) yes ( ) no (by the way: this can also been seen in z3c.formdemo on the All widgets page widgets.html) Well nice - after all this reflects the behaviour of boolean values: they can be either yes (True) or no (False). Actually I preferred formlibs behaviour of rendering checkboxes for Bools though, something like: [v] I. e. a single checkbox that can either be checked [v] or not [ ] should suffice for a boolean value. - This is shorter than the radio buttons and just as good. Now I was hoping that this was implemented in z3c.form.browser.checkbox already: class AdrEditForm(form.EditForm): fields = field.Fields(IAdr) def MyFieldWidget(field, req): return widget.FieldWidget(field, checkbox.CheckBoxWidget(req)) fields['invitation'].widgetFactory = MyFieldWidget However I get *two* checkboxes now [ ] yes [ ] no for the one boolean field invitation - that's not exactly what I was looking for: *one* checkbox should be enough for a Bool field - and what should happen by the way, if I check both boxes ([v] yes [v] no)? I think there should be an easy way to do this. This is very common after all. - Any hints?

[Zope3-Users] z3c.form, style-attribute of TextWidget, TextAreaWidget
Given a simple interface IPerson with some TextLine (Text) fields
class IPerson(Interface):
a person
nachname = TextLine(
title=uNachname,
...
)
vorname = TextLine(
title=uVorname,
...
)
anrede = TextLine(
title=uAnrede,
...
)
sonst = Text(
title=u'Sonstiges',
...
)
I should be able to give the widgets some custom appearance by
not only appending to their klass-Attribute (w.addClass()) but also
by setting their style-Attribute (w.style) like this
class PersonEditForm(subform.EditSubForm):
fields=field.Fields(IPerson)
prefix='person.edit'
def updateWidgets(self):
super(PersonEditForm, self).updateWidgets()
sty={'anrede': u'width: 55px;',
'vorname': u'width: 105px;',
'nachname': u'width: 105px;',
}
for k in sty.keys():
w=self.widgets.get(k)
w.style=sty[k]
w.addClass(in)
The widgets do have a style-Attribute after all and this used
to work in formlib. - However this has no effect when rendering:
input type=text id=person-edit-widgets-nachname
name=person.edit.widgets.nachname
class=textWidget textline-field in
value=.../
...
There is just no style attribute. - I would expect something like:
input type=text id=person-edit-widgets-nachname
name=person.edit.widgets.nachname
class=textWidget textline-field in
style=width: 105px; value=... /
Having a look at text_input.pt in my z3c.form egg shows why: style is
just ignored there. If I add the style attribute there, everything
works fine:

It seems other people where having similar troubles, see e. g. http://www.nabble.com/Problems-with-ZODB3-3.9.0_dev_r77011-t4109664.html however it is not obvious to me how to exactly apply the solutions proposed there to my code - there is no external file (like an image) involved in my code. The example is not to long, however it is not trivial: uses formlib, an object in its schema, object widgets, object widget dispatcher etc. - I have therefore included the complete example. - for convenience: I have also put it online (my old university account) $ wget -nd http://user.cs.tu-berlin.de/~reuleaux/contacts.tgz $ tar xvpzf contacts.tgz $ cd contacts edit buildout.cfg as you see fit, you might for example change the eggs-directory maybe adjust the mngr user/passwd in src/contacts/app.zcml $ python bootstrap $ ./bin/buildout $ ./bin/instance start usage / steps to reproduce: go to http://localhost:8080 log in as mngr and add some contacts - that works fine now edit such a contact (say I have given it a name rx) http://localhost:8080/rx/edit and try to save it: boom! I am aware that object widgets are kind of superseeded with the advent of z3c.form - and I really want to go in that direction but for the time being my programming would be much more relaxed if I got this example working, I could really need a helping hand here, thanks. -Andreas interfaces.py from zope.interface import Interface from zope.schema import TextLine, Object class IAddr(Interface): an address. street = TextLine( title=ustreet, description=uthe street, required=False, missing_value=u'' ) city = TextLine( title=ucity, description=uthe city, required=False, missing_value=u'' ) zipcode = TextLine( title=uzip, description=uthe zip code, required=False, missing_value=u'' ) class IContact(Interface): a contact name = TextLine( title=uname, description=uthe name, required=False, missing_value=u'' ) firstname = TextLine( title=ufirstname, description=uthe firstname, required=False, missing_value=u'' ) addr=Object( title=u'address', description=u'the address', required = False, schema=IAddr) addr.py from zope.interface import implements from interfaces import IAddr from zope.schema.fieldproperty import FieldProperty from persistent import Persistent class Addr(Persistent): Eine Addr. implements(IAddr) street = FieldProperty(IAddr['street']) city = FieldProperty(IAddr['city']) zipcode = FieldProperty(IAddr['zipcode']) def __init__(self, street=u'', city=u'', zipcode=u'', titel=u'', geb=u'', fkt=u''): self.street=street self.city=city self.zipcode=zipcode contact.py from zope.interface import implements from interfaces import IContact from zope.schema.fieldproperty import FieldProperty from persistent import Persistent from zope.security.proxy import removeSecurityProxy # from zope.app.container.contained import Contained # class Contact(Contained, Persistent): class Contact(Persistent): a contact. implements(IContact) __name__ = __parent__ = None name = FieldProperty(IContact['name']) firstname=FieldProperty(IContact['firstname']) addr = FieldProperty(IContact['addr']) def __init__(self, name=u'', firstname=u'', addr=None, ): self.name=name self.firstname=firstname self.addr=addr # def __getstate__(self): # s=Persistent.__getstate__(self) #s['addr']=removeSecurityProxy(self.addr) #return s views.py from zope.formlib import form, namedtemplate from zope.app.pagetemplate.viewpagetemplatefile import ViewPageTemplateFile from interfaces import IContact from contact import

[Zope3-Users] zc.buildout beginner's question
I am aware that a lot of fancy stuff can be done with zc.buildout, however I am just starting... I found Benji's blogs a good entry point: [1] http://baijum81.livejournal.com/19795.html [2] http://baijum81.livejournal.com/20551.html I got z3hello running - hey, that was not to hard - and decided to use that as a starting point / playground for my own experiments: mydemo, just doing some trivial changes: * rename z3hello to mydemo throughout * removing the .svn subdirectories (I am not checking anything in, nor do I want svn to get confused should I later check in to somewhere) * remove the urls: neither do I want my demo to be registered in pypi (yet) nor somehow uploaded to Benjis place * etc. So I now have my own little buildout mydemo to play with. Cautious as I am I save that as a Skeleton $ cp -rp mydemo mydemo-skeleton i. e. *before* running the following cmds in mydemo $ python bootstrap.py $ /bin/buildout -N $ /bin/instance start no I can go to: http://localhost:8080/mydemo And the page says Hello Now being a programmer I make only a little change to make my page say Hello from Rx and save that, I could go own from here making changes till I got a full blown application. However at this point I want to make sure I can get back to the original mydemo layout (before bootstrapping/starting) i. e. I want some way to save my work in a directory say mydemo1 that is nearly identical to the original: $ diff -f mydemo-skeleton mydemo1 should only reflect my change: Hello - Hello from Rx roughly make clean if I was using make some ideas: * $ ./bin/buildout setup . sdist somehow produces an egg in dist/mydemo-0.1.tar.gz but that has not the other files: bootstrap.py, bootstrap.py, setup.cfg * I saw fancy uninstall recipes in Jim's slides - do I really those? http://svn.zope.org/zc.buildout/trunk/doc/tutorial.txt?rev=76281view=auto pdf: http://www.zope.de/redaktion/dzug/tagung/potsdam-2007/folien/introduction-to-zc-buildout.pdf/download * or uninstall_service in entry points - - not sure yet what entry points are good for * there should be some easy way to clean up? Totally different question: When using a zope from svn I could watch the log file z3.log $ tail -f z3.log while I was (re)starting/stopping the daemon that was convenient What needs to be done to make Benji's z3hello log to some file? -Andreas ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Re: [Zope3-Users] Guidance on accessing MySQL db.
Admittedly there has not been much documentation of connecting Zope 3 to a relational database like MySQL. - Personally I don't have much experience either. Some hints anyway: The preferred way is to use an ORM * either SQLObject - then use sqlos http://codespeak.net/z3/sqlos/ * or sqlalchemy - then you have two choices - the older one: http://svn.zope.org/z3c.zalchemy/trunk demos: z3c.zalchemy/trunk/src/z3c/zalchemy/demo - the younger one: http://svn.zope.org/z3c.sqlalchemy/trunk/ (I would go for z3c.sqlalchemy) Also have a look at http://svn.zope.org/mysqldbda/trunk/ for a connection without an ORM (not sure in what shape that code is) Maybe the authors of those packages can give better advice. -Andreas On Fri, Mar 30, 2007 at 03:32:16PM -0700, Rich C wrote: Hello all, I've just started using Zope 3 and am having some difficulty finding examples on a good way to access a MySQL database. For the moment, I'd just like to be able to read from the database and display it in a web page with decent formatting. I've read examples from Zope 2 where they used a DTML page that called a ZSQL method such as the following: dtml-in river_info dtml-var river_id dtml-var river_name /dtml-in ZSQL method would then contain: SELECT river_id, river_name FROM river_info In Zope 3, I only see an option to add a SQL script which I'm pretty sure is not the same thing as a ZSQL method since I've copied the above into a SQL script and Testing the script by itself does in fact read from the MySQL database, but I can not access the SQL script from a DTML page. I get the following error: KeyError A server error occurred. So, some very basic questions : What is the suggested way to access a MySQL database from Zope 3. Should I even be creating DTML scripts, my understanding was that there are better ways of doing things than with DTML in Zope 3.

Yes, it is still a very valuable text, Stephan just has plenty of other things to do and hasn't found the time to update the book (he can tell you better if and when there will be an update). But this is a general problem of computer texts: It takes some effort to keep them up to date. Note that this is still Stephans book, not a book written by the Zope 3 community (don't know if he would be interested in having more people maintain the book). You might want to read Stephans book in parallel with Philipps book and find out which suits you better in which area.

[Zope3-Users] state of pure Zope 3 CMSs?
I wonder what is that state of pure Zope 3 CMSs? - Cubic and z3ecm come to mind, see below. I am aware that sytems like *Plone* offer everything you can imagine for serious CMS development. But being based on Zope 2 (and just slowly moving towards Zope 3 by means of Five) they also carry a lot of baggage with them: * Say you want to develop a Plone product based on Zope 3 (Five): You effectively have to master Zope 2, Plone and Zope 3. * On my debian system (after installation of plone-site) du -h /var/lib/zope2.8/instance/plone-site/Products/ gives me: 19M - that's a lot. Many portals start out as some small projects and might not need all the fancy stuff. Being small in code and therefore easily manageble might be more important. Besides: if they where solely based on Zope 3, adding more stuff to them should be easier anyway (by means of adapters e. g.). Cubic and z3ecm come to my mind - are there more? Cubic - I was able to check it out into my zope 3 (svn trunk) tree with svn co http://svn.amazesolutions.com/zope3/cubic/trunk cubic And after replacing some MessageIdFactory occurences with MessageFactory I was able to run it, but actually adding a Cubic portal resulted in an error: File /home/reuleaux/z3/src/zope/app/keyreference/persistent.py, line 41, in __init__ raise zope.app.keyreference.interfaces.NotYet(object) The former home page http://opensource.amazesolutions.com/projects/zope3/cubic doesn't exist any more. I didn't find a mailing list. Was it ever meant to be usable for some small portal sites. Or was it just a toy project, some experiment? z3ecm - I am aware that this is an ambitious joint effort of Nuxeo and Infrae to create the infrastructure of a next generation CMS. But looking at the web site http://www.z3lab.org/ I could find some fancy video animations, but no tutorial/introduction/readme.txt/install.txt how to install and how to procede next. Well the About page (http://www.z3lab.org/sections/about) gives an excuse (...So don't expect to find here anything usable from a user point of view...) and I saw that in the last entry on the mailing list archive http://lists.nuxeo.com/pipermail/z3lab/2006-August/000991.html someone is asking the same question: Can someone help get me to a point where I can play with z3ecm? On the same About-page they welcome everybody to work on the project - Honestly, my interest in a project that I cannot even install is not very high. I might even misunderstand z3ecm altogether: Will there ever be a CMS based on zope3 and z3ecm only. Or will it for years to come just be a bridge techique: Zope2 + Five(Zope 3) + Z3ecm + Silva/CPS? Well I guess I should ask this on the z3ecm mailing list. - but I thought the idea of having a pure Zope 3 CMS was of general interest. -Andreas ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Re: [Zope3-Users] SFTP , SSL
I just read Davids answer - interesting - and I am a bit confused: So HTTPS seems to be working now, supported and enabled? - Is this the official status for SSL now? Or is it just working on Mac OS X, is pyopenssl officially required - if so, then I think this should be stated somewhere in the release notes. I must admit it has been a while that I tried HTTPS (with no succes at that time) and the (disabled for now because of error handling problems) that I found in the release notes was just the explanation I found convincing at that time. -Andreas On Fri, Jun 16, 2006 at 06:53:02PM -0300, David Pratt wrote: Hi Mike.

[Zope3-Users] binding z3 to localhost only (security) / xmlrpc via https
If have successfully setup zope3 behind a ssl-enabled apache2 (apache and zope3 both running on the same host mousehouse) using ProxyPass and ProxyPassReverse directives as described in Philipps book in chapter 17, example 17.3.1, i. e. I can reach zope with https://mousehouse/... Now I want to bind zope3 to localhost only, in order to make sure it can *only* be reached with https://mousehouse/..., *not* with http://mousehouse:8080 any more. This should be possible (and is mentioned in Philipps book on page 303, Only binding it to localhost ensures that noone from the outside gains access to Zope directly). I just haven't figured out how to do this, maybe I have overlooked something. How do I bind it to localhost only? A related but different question: I have some xmlrpc scripts that work in a fashion like this import xmlrpclib URL='http://user:[EMAIL PROTECTED]:8080/somefolder' book=xmlrpclib.ServerProxy(URL, allow_none=True) [do stuff with book] They don't work any more with URL='https://user:[EMAIL PROTECTED]:8080/somefolder' Is there anything special needed to make xmlrpc scripts work with zope through ssl+apache? Thanks in advance. -Andreas ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
Re: [Zope3-Users] binding z3 to localhost only (security) / xmlrpc via https
Please ignore the second question, my fault: xmlrpc works fine via apache+ssl, just had to leave out the :8080 URL='https://user:[EMAIL PROTECTED]/somefolder' On Sat, May 06, 2006 at 11:09:50PM +0200, Andreas Reuleaux wrote: ...

Re: [Zope3-Users] ZODB - root and transaction
I can't really point at your problem, sorry. But I have a similar
script to fill my ZODB which works for me. You might want to try to
experiment with this / modify your script ...
#!/usr/bin/env python2.4
# -*- coding: utf-8 -*-
from ZODB import FileStorage, DB
import transaction
# ...
fs = FileStorage.FileStorage('/home/reuleaux/z3/Data.fs')
db = DB(fs)
con=db.open()
root = con.root()
app=root['Application']
bookfolder=app['bookfolder']
# ...
bookfolder[name]=b
transaction.commit()
db.close()

Hi,
I have got two problems, which are related:
1. How do get a reference to the root object of the ZODB everywhere?
I mean I have found a solution like something:
db = zapi.getUtility(IDatabase)
conn = db.open()
root = conn.root()
root['123'] = newbook
But it does not acutally store the object in the database.
I try to commit it, but
conn.getTransaction.commit()
won't work. I search instead for get_transaction(), but I didn't found it in
Python 's lib directory.
So, how do I save it???
2. How do I get (the current) transaction?
Thanks a lot in advance!

Re: [Zope3-Users] practical example of migrating from services to utilities

This example involves the getting menus items with the getService/getUtility functions and is taken from Philip's worldcookery example code. Here's the pertinent zcml (worldcookery/browser/configure.zcml): browser:menu id=alternate_views title=Menu containing a list of alternative views for an object / browser:addMenuItem title=[label-recipe] Recipe class=worldcookery.recipe.Recipe permission=worldcookery.EditRecipes view=AddRecipe.html / Here's the original code (worldcookery/browser/recipe.py): def alternateViews(self): menu_service = zapi.getService(servicenames.BrowserMenu) menu_id = 'alternate_views' return menu_service.getMenu(menu_id, self.context, self.request) Here's the modified example that I'd want to check if I am doing correctly: def alternateViews(self): browser_menu = zapi.getUtility(IBrowserMenu, 'alternate_views') return browser_menu.getMenuItems(self.context, self.request) Am I doing this properly? ... I haven't tried your solution zapi.getUtility(IBrowserMenu, 'alternate_views') (I doubt it works) but I had the same problem some time ago, and Philipp had pointed out to me that there are simpler solutions now - both of them worked fine for me (his original e-mail to me in German below, the English translation is mine): There is no global browser menu service available any more. And there is no corresponding utility, as for most of the other services. Menu items are simply adapters in Zope 3.1. The helper function getMenu from zope.app.publisher.browser.menu is handy for the lookup. The method alternateViews() from example 12.3.3 can now be written as def alternateViews(self): menu_id = 'alternate_views' return getMenu(menu_id, self.context, self.request) Besides that there is an even easier to use view view_get_menu (that Philip regrets to not have mentioned in his book). Example 12.3.4 could be written as li tal:repeat=item context/@@view_get_menu/alternate_views ... /li This worked in Zope 3.0 already (and has not changed in Zope 3.1) It can also be recommended as there is no requirement for an additional method in a view class. Regards, Andreas (from Philips E-mail:) Der Global Browser Menu Service ist komplett weggefallen. Eine Entsprechung als Utility, wie das mit den meisten anderen Services der Fall ist, gibt ebenfalls nicht. Menü-Einträge sind unter Zope 3.1 einfache Adapter. Die Hilfsfunktion getMenu aus dem zope.app.publisher.browser.menu Modul erleichtert das Lookup. Die Methode alternateViews() in Beispiel 12.3.3 könnte nun folgendermaßen implementiert werden: def alternateViews(self): menu_id = 'alternate_views' return getMenu(menu_id, self.context, self.request) Es gibt übrigens auch den etwas leichter zu bedienden View view_get_menu, den ich leider vergessen habe zu behandeln. So könnte Beispiel 12.3.4 ab Zeile 20 auch heißen: li tal:repeat=item context/@@view_get_menu/alternate_views ... /li Diese Methode ist transparent gegenüber den Änderungen von X3.0 zu 3.1 und insofern auch empfehlenswert, allein schon weil eine zusätzliche Methode in der View-Klasse entfällt. ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
