[Zope-dev] Five and browser-oriented components
On Z2, certain imports need to come from Products.Five, to play nicely with ZPublisher and friends. I'd like to ask for the motivation for not patching it onto the existing classes and/or modules. The effect of having Z2-developers import from Products.Five is that they must opt out on packages that make use of templates, browser views, formlib, ... --- and it adds needless complexity. This split might also have prompted the Plone community to walk their own way to the extend that there isn't much code reuse outside of the core Zope packages (along with egg dependencies, but with our fake eggs, we're almost up to par here). \malthe ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Malthe Borch wrote: On Z2, certain imports need to come from Products.Five, to play nicely with ZPublisher and friends. I'd like to ask for the motivation for not patching it onto the existing classes and/or modules. Technically, I think that this is going to be hard. You'd need to patch in the magic acquisition base class. Acquisition is the main reason that some of the code needed to be duplicated - without the existence of acquisition wrappers, security checks are not made for view access and things just won't work. We do explicit acquisition in those bits of code, but it's still a pain and leads to confusion around self.context in views being acquisition-wrapped weirdly, breaking some expectations around aq_parent. The other argument against monkey-patching is that monkey-patching is something to be avoided if at all possible. I think it's wise to avoid it here, as it's possible. If you monkey-patched core Zope 3 classes, the chances are that you'll break Zope 3 code that assumes certain behavior. The way to get rid of many of these problems would be to get rid of the need for acquisition. Philipp started a branch long ago that allows the acquisition system to look at a __parent__ pointer if no acquisition wrapper is present. Since our views have __parent__ pointers, this should fix the issue. This branch has been lingering in an almost ready state for a long time now. In general, I think acquisition is one of the major remaining stumbling block in enabling quite a bit of straightforward Zope 3 code in Zope 2.

You might be right; but it's a very bad place to be, stuck in the
middle of two frameworks. We're duplicating code all over the place,
and while this has obvious inherent qualities, it also wears us out as
a community.
I think I found a useful pattern for how to work with z3c.forms to avoid
duplication. For each page that has forms, I make two views; one is the
Products.Five.BrowserView view that's looked up by the publisher and is
registered with ZCML. The other is my z3c.form.form.Form that does the
actual work and renders my content area. The relationship between these
two forms is similar to that of forms and subforms.
Here is an example of how this looks like in practice:
class MyForm(z3c.form.form.Form):
template = Z3ViewPageTemplateFile('form.pt')
fields = z3c.form.Fields(ISomething)
@button.buttonAndHandler(_('Apply'), name='apply')
def handle_apply(self, action):
data, errors = self.extractData()
# ...
class PloneView(Products.Five.BrowserView):
__call__ = Z2ViewPageTemplateFile('main.pt')
form = MyForm
def contents(self):
z2.switch_on(self)
return self.form(self.context.aq_inner, self.request)()
Here, main.pt is the part that renders main_template and pulls in
view/contents into the content area.
z2.switch_on() is a compatibility function that fiddles a bit with the
Zope 2 request to make it work with z3c.form (and also calls Five's
decodeInput).
Of course, PloneView is generic enough to be subclassed at this point:
class MyFunnyView(PloneView):
form = MyFunnyForm
What's the advantage of this separation?
- You don't have to worry about Acquisition in your form code, which
will make out the bigger part of your code. The implications of
Five's BrowserView being derived from Acquisition.Explicit has often
left me confused. (Death to self.context.aq_inner!)
- You can reuse form code between Zope 2 and Zope 3.
- Your forms can be rendered in any part of your page, like in
portlets.
- No subclassing of classes in z3c.form is necessary to use the forms
in Zope 2. (In contrast to Five's current way of subclassing
formlib.)

[Zope-dev] [zope.testing.doctest] a nasty surprise
As the community (apparently) strongly favors doctest over unittest, I wrote my first test based on zope.testing.doctest. And promptly, I was badly surprised In order to analyse a difficult problem, I added from dm.pdb import zpdb; zpdb.set_trace() in the doctest (dm.pdb.zpdb is my Zope aware PDB extension) -- and got a TypeError: set_trace requires at least one argument, 0 given. Now, I know the zpdb.set_trace() does not want any arguments. I moved the line from the doctest code into the failing infrastructure code -- same TypeError. I called help(zpdb.set_trace) and got: Help on function set_trace in module zope.testing.doctest: set_trace(self) Apparently, doctest has overridden zpdb.set_trace in an incompatible way I will rewrite my test as unittest and probably avoid in the future zope.testing.doctest whenever possible. -- Dieter ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Quite possibly z3c.sqlalchemy has a release that actually works. One out of three is not bad... :) We are going into production with collective.lead and are committed to releasing the 1.0 branch as 1.0. sqlite works just great for us, we use it to run unit tests and for developers that just need to adjust the styling and such. The production environment will run against Oracle. The elro-tpc branch (which, I was told, is the future) doesn't appear to work with sqlite out of the box. I think this is a temporary bug, as Laurence pointed out, caused by SQLite not supporting two-phase commit. It should be fixed before release, by adding a one-phase fallback. I'm curious how to do functional tests with collective.lead - I'd like to have some real easy way to get the database set up and tore down down in my tests. Are you doing this? I'm doing a lot of it in Java. :) The typical pattern is to use a test setup that does database clean-down to return it to a steady state. Test data is kept in a declarative file (e.g. with an XML syntax that maps to DB structure) and used to initialise the database before each run. Doing nested transactions and rollback would be nicer, but probably doesn't work in all cases since app code may well do explicit commits. Note that sqlite does not support nested transactions or savepoints. It's never particularly pleasant.

In addition: we often do use environment variables and .ini files for additional configurations. Introducing another configuration language is stupid.

Or: i18n:translate=reload_this_catalog or some other unique message id. But the above code should work. Well, using PlacelessTranslationService as i18n:domain is strange. You should use the name of your own product/package. Modified language preferences for browsers - (Mozilla Firefox 2.0.0.4 and MS-IE 7.0.5730.11) to set German [de] as primary langage. When I viewed above page in firfox got the corresponing german translation (Diesen Katalog neu einlesen) as specified in related .po file. But with MS-IE, no luck, gives same string - Reload this catalog So is it browser specific/dependable ? It should not. Do you have a way to check which browser headers are sent by IE and firefox and if they differ in the language preference? Another thing I tried is adding attribute i18n:target=cs, but it seems to have no effect, firefox gives german translation as per language settings as MS-IE gives same string - Reload this catalog Does it means that attribute target is not supported ? Is there any list/documentation about supported i18n attributes ? I have never seen that attribute. From the top of my head, these i18n attributes are used in zope: translate, domain, name and attributes. Also I was not able to find references/examples for DTML, does DTML supports i18n/L10n ?

Let's say that the user doesn't submit file3, on that case, zope will
generate something like this: some_ramdom_id.dat and it will attach
an empty file. I tried something like this:
dtml-if file1.filename not in ['', None]dtml-boundary
type=application/octet-stream disposition=attachment
filename_expr=file1.filename
dtml-var file1.read()/dtml-if
However when I try to save, zope fails and says:
Error Type: Document Template Parse Error
Error Value: Unexpected tag, for tag dtml-boundary
type=application/octet-stream disposition=attachment
filename_expr=file1.filename , on line 215 of sendAnfrage
The only way I found to cope with this was doing a script to validate if a
file has whether a name or not, then I will return a dictionary like this:
{'name': real_name_or_dummy_name, 'data': file.read()_or_dummy_text}
So, I feed the boundary with a dummy file when no file was uploaded. I
don't
really like to send dummy files since it may confuse the person receiving
the emails. Is there any better way of achieving this? Please note that
since I'm working in the zmi and I'm not the administrator of the machine
where my page is hosted, I can only use dtml to send mail :-(, thus using
the python mail library isn't an option on this case.

But if I change domain (e.g i18n:domain=mydomain) it doesn't work. Is domain attribute is related to the domain specified in .po file, coz the example .po file which comes with PlacelessTranslationService has domain as 'PlacelessTranslationService' and if I used same it works fine. Yes, the two should be the same. But if you use this domain and other people use it too because it is the standard example then you can get conflicting translations. Yes completely agreed. I tried changing domain in given example .po file (e.g. to Domain=mydomain\n), but it doesn't work even after doing Reload catalog for corresponding .po file object using PTS ZMI. I found reload catalog works if we modify message ids/text. Any idea how PTS manages this headers (like Domain/Content-Type etc) ? Is it possible to reload/refresh/rebuild this information ?

Re: [Zope] Conditional dtml-boundary in dtml-sendmail
How is dtml more error-prone than python? I'd imagine that all depends on who's authoring it. On Wed, Apr 9, 2008 at 11:59 PM, Andreas Jung [EMAIL PROTECTED] wrote: --On 9.

Re: [Zope] Re: i18n/L10n support in zope2
I tried changing domain in given example .po file (e.g. to
Domain=mydomain\n), but it doesn't work even after doing Reload
catalog for corresponding .po file object using PTS ZMI. I found
reload catalog works if we modify message ids/text. Any idea how PTS
manages this headers (like Domain/Content-Type etc) ? Is it possible
to reload/refresh/rebuild this information ?
While working further I found following work aroud ( may not be on
correct path, but it works)
-- Edit the headings part (e.g Domain/Language etc) for .po files and
save file.
-- Make use of PTS ZMI to delete corresponding ZODB object of .po file.
-- Restart Zope.
I also found workaound for MSIE behaviour, include heading call
X-Is-Fallback-For: ?\n in your .po file. For e.g -
X-Is-Fallback-For: de-de\n.
After making change and updating sample page template - (English as
primary language for both browsers)
html
body
English -
span i18n:domain=English i18n:translate=

Interest thing is that MSIE respects selected language hierarchy where
as FireFox gives preference to the primary one.

[Zope] Re: Conditional dtml-boundary in dtml-sendmail
The 'email' module is part of the standard Python distribution since generations. Well, I said allowing or installing. I wasn't sure if it was and with allowing I meant by using allow_module or allow_class. I guess you can't just use this module without removing security assertions. I will try to confirm this. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

That is very strange:
zopectl debug uses almost exactly the same startup sequence

Thus, if your Zope starts at all, zopectl debug should start.

zopectl fg starts. Would need to see the starting sequence?
Really funny
Unfortunately, this means that is will be quite difficult
to find the cause of your problem.
One approach would be to emulate in a pure Python interpreter
what zopectl debug would do for us.
You may try:
bin/zopectl shell # will create a new shell process with the correct
environment
your_zope_python
from Zope2.Startup.run import configure
configure('etc/zope.conf')
# this is likely to raise the exception you have earlier reported
from pdb import pm
pm() # analyse the exception context
I will try that. Any thing happens I report back to the list.
Best regards,
Manuel.

[Zope] Upgrade to 2.7.2 results in all content unavailable
I upgraded to Zope 2.7.2 and all of my content can't be seen by Zope.
Honestly I'm not sure what the previous version I was running was (nor
am I sure how to find out).
Now, every page results in
Site Error
An error was encountered while publishing this resource.
Resource not found
Sorry, the requested resource does not exist.
Check the URL and try again.
Resource: Zope GET
There is effectively no more web interface.
I've verified that the database still seems to be there in
[instance]/var/Data.fs and hasn't been touched since the update.
I tried going through some of the steps in the Troubleshooting and
Debugging page
http://www.zope.org/Documentation/Books/ZDG/current/TestingAndDebugging.stx
I can do a ZPublisher.Zope('/manage') in python and see that it returns
a Resource not found page.
Interestingly, my log which was being written to /var/log/zope started
writing to the default location after the install.
I feel like there isn't enough here to determine whether there is a bug
or whether I've mucked something up myself. But perhaps some gentle
guidance would help me determine whether there is a bug or just my own
ignorance.
Was there a config file that got overwritten in the update? Where would
it be?
Perhaps there are some clues in the lines written to the log file upon
startup.

[Zope] retrieving a single column from database and giving it as hyper link fetching respective data
Dear all, I'm developing a biological database using Zope 2.6 and pgsql. Let me explain my issue with an example. There is a menu called Drug in my homepage, by clicking the menu the drug names along with their type in two different columns get displayed in the body. I can do things till that. My problem is , lets say there is a link called Isoniazid with all other links(drug names) in it. When a user clicks one of the links as i said before as isoniazid only the information about isoniazid has to be retreived and displayed , likewise to all the other drug links. I have no idea how to capture the click event and the data to be retrieved. Can someone help. Thanks in advance. And another query, how can i select text from a dropdown box. I just need the data which is selected in the dropdown box and sent as query.

If you're application works then better stick with your working solution. 2.7 is out-dated since a long.
