[Zope-dev] Namespace Questions
Hi,
I want to find an efficient way of adding a
dictionary of values to the Zope namespace, where a different dictionary could
be set on each request.
I wanted to create a several dictionaries each
containing properties for a look and feel (i.e. background colors, fonts etc),
and switch them for each request.
For example I'd like to do something similar to
what's done below (although the method below doesn't work).
dtml-call
"REQUEST.set('LookAndFeel',m_getRandomLookAndFeel())"
(assuming the Look and Feel Dictionary has key's
LOOK_COLOR, and LOOK_FACE)
dtml-with LookAndFeel
font color="dtml-var
LOOK_COLOR" face="dtml-var LOOK_FACE"
I know the with doesn't
work for the dictionary, but would like to do something similar to this
example.
/font
/dtml-with
thanks in advance,
Adam
[Zope-dev] Making Folders callable
Is there any reason that Folders aren't callable?
That is, you can't directly render a folder with dtml-var
nameofafolder. You have to do something like dtml-var
"nameofafolder.index_html(_.None, _)". But, that's not quite the same
because if the folder lacks an index_html, it gets acquired.
Here's an extra method that can be added to lib/python/OFS/Folder.py, or
to ObjectManager.py, to make Folders render nicely.
# XXX hack to make folders render
# retains compatibility with current behaviour
# if the folder doesn't contain index_html
def __call__(self, *args, **kw):
""" mandatory docstring """
index = self._getOb('index_html', default=None)
if index is not None:
args = (self,) + tuple(args[1:])
return apply(index, args, kw)
return ''
Is this a good idea? Should this go into the Collector as an RFE with
patch?
Actually, I'm not sure why it should be tuple(args[1:]) -- I just copied
that out of ZCallable in the latest PTK CVS. I'd guess you'd want to
check the first argument (client) for whether it is None before
replacing it with self.
Perhaps something like this:
args = (len(args)0 and args[0] or self,) + tuple(args[1:])
Discussion welcomed.

[Zope-dev] Re: ZCallable
Yup, This looks good, as did your earlier post. However, it raises a question :( Something like a ZCatalog or a Squishdot Site (which I have a passing interest in ;-) are both folderish. However, their __call__ method does something quite different: it returns the results of searching the catalog (I think this is the ZSearchable Interface, correct me if I'm wrong ;-) I guess what's bothering me is why __call__ has this dual role and how the rendering process manages to correctly render index_html even on a Squishdot object which is actually callable? Hmm... I guess the implication of this is that a normal folder will never render itself to avoid confusion over the ZSearch interface and so if I want this behaviour I'll have to roll-my-own folder which inherits from ZCallable. Any ideas/comments? Chris PS: Shane: what's the difference between ZCallable and the ZRenderable base class that Maik Roeder mentioned on [EMAIL PROTECTED] a few days back?

Re: [Zope] Variable sort in dtml-in
In my search form, I have a selection box "in_sort_by" whose value can
be "Category", "Field", or "Title". I am trying to make dtml-in sort by
this value. I am using:
dtml-in SQL_search sort="_['in_sort_by']" size=list_size
start=query_start
Hi Aaron again
I have attached appropriate patch for dtml-in tag for Zope 2.2.0b3/b4
(Of course this patch was checked and works ok).
Just for you, the syntax of my patch for dtml-in should be:
dtml-in SQL_search sort="expr:_['in_sort_by']" size=list_size start=query_start
or best and simply (and strict equivalent above):
dtml-in SQL_search sort="expr:in_sort_by" size=list_size start=query_start
I want extend my proposal to others attributes like eg. size:
dtml-in SQL_search sort="expr:in_sort_by"
size="expr:REQUEST.user_list_size"
start=query_start
It is possible easy extend other DTML tags through the same way too,
but I dont know what other zopistas (especcially from DC) thinks about this.
My syntax proposal is one which not caused serious comtatibility problems.
Eg. natural syntax attr="something" is treated (unfortunately) as attr=something
and therefore would not be adapt and apply for indirect lookup of attribute
without breaking of compatibility.
Very please all for comments.

I'd just like to know what the Linux community have tested and found suitable I am currently using Webmaker but it doesn't support DTML tags or syntax checking I have also been asked to mention Dreamweaver I noticed that Dreamweaver has a Coldfusion CFML plug-in Is anyone interested in developing a similar plugin for DTML I am only a novice python programmer but would be willing to help if anyone feels it is worthwhile Just some ideas as I am a python/Zope newbie but like what I have seen so far. i can only offer limited help at this stage but would be willing to help wherever possible if a guru needs a disciple. thanks to all those who have and are contributing to Zope.

Re: [Zope] Newbie: Zope a webserver? Serving PHP and Perl
On Thu, Jul 13, 2000 at 05:44:23PM -0500, Lucas Young (c) wrote: Have just installed Zope under Win2K and it works fine - I see a lot of people mention using Apache to server Zope, but isnt Zope a webserver itself? I can browse to http://server:8080/ and view Zope pages, so why would I need Apache? Also, How do I set Zope up so it handles PHP tags? Your second question answers your first. Zope's ZServer does indeed serve HTTP, but it only serves Zope objects. Apache, on the other hand, allows you to serve much more, including PHP. You can use Apache to integrate the two, there's a How-To on Zope.org that explains how to do this, IIRC. Basically, reasons for using Apache are: - Using SSL (but there is an addon product for ZServer that covers this as well) - Integration with other content, like static files and, in your case PHP. - Virtual servers, competing for ip addresses or ports. - Serving virtual servers out of Zope. This is not a complete list, but these are the most important reasons. On the other hand, using Apache introduces another level of complexity to your setup, introducing a speed bump, a potential source of misconfiguration problems, and another link in the chain that could break. -- Martijn Pieters | Software Engineermailto:[EMAIL PROTECTED] | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ | ZopeStudio: http://www.zope.org/Products/ZopeStudio - ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

[Zope] ZPygres connection problem
Hello! I did an experiment (after having problems connecting Zope to Postgres) - I stopped ZServer and restared Zope in PCGI-only mode. I opened connection successfully! I stopped PCGI and restarted ZServer. I again got BadRequest (cannot connect to server). Anyone have an idea why Zope+ZServer cannot connect, while Zope-PCGI can?

RE: [Zope] upgrade to 2.2 zsql authentication problem
I create a zsql method in 2.2b4, using the test tab the zsql method works ok. The problem is when I use a dtml method or document (executable objects) to call the zsql method with a IN statment, a not authorized browser box appears. I'm aware of the ownership changes but on my port I'm having this problems only with zsql methods so I wonder if this is only related with this product before diving into the ownership issues.

Re: [Zope] Weird problem with Z MySQL Connection
Hi all, Keep getting an 'invalid connection string' error when trying to make a database connection from Zope. Weird thing is that I first moved a working build to another machine, which resulted in it not working anymore. Did a clean install of Zope 2.1.6 (Source), MySQL 3.22.32 and all necessary Zope products (ZMySQLDA 1.2.0) using the same packages used in the working install. Still no dice. Same setup :( Well, I've solved the problem by installing Zope from RPMs and having it connect to MySQL via TCP/IP instead of the default unix socket. So don't connect to 'localhost', connect to your machine's hostname. File /usr/share/zope/lib/python/Products/ZMySQLDA/db.py, line 155, in __init__ BadRequest: (see above) Why is Zope looking for files in '/usr/share' all of a sudden? It didn't in the first install. I haved searched the mailinglist archives already, tried stuff suggested there with similar problems. Still no dice :( But this still isn't solved. Where can I specify the path it shouldn't be looking for the ZMySQLDA stuff if it ain't in '/usr/share/zope'?

RE: [Zope] testing for local roles
Well, while we're on the subject of AUTHENTICATED_USER.has_role, I've
just come upon an error that just popped up all of a sudden in an SQL
query that was working fine before. The problematic line is:
dtml-if "AUTHENTICATED_USER.has_role('Manager',this())"
and the error I get when trying to test it is:
Error, exceptions.NameError: AUTHENTICATED_USER
snip
Another query in the same folder uses the exact same if statement, and
works fine. I am running 2.2b4. Can anyone suggest a solution?
Aaron -
Are you passing AUTHENTICATED_USER as an argument to the
query that is working (and not doing so on this one?)
Remember that SQL methods don't automagically get the
same namespace that DTML does - the only things it can
use are attributes that are named in the arguments list
(this is to prevent names that are coincidentally the
same in a REQUEST form or something from being inserted
into queries).
One common way of doing what you want is to add REQUEST
to the arguments list of the SQLMethod and use:
dtml-with REQUEST
dtml-if "AUTHENTICATED_USER.has_role('Manager',this())"
select * from data
/dtml-if
/dtml-with

[Zope] Accessing the Application (or Control_Panel)
Hello,
I am working on a Python Product (subclass of ObjectManager) that creates
some instances of a few ZClasses inside itself when constructed.
Currently, I do this as follows:
CONTROL_PANEL = None
def manage_addMyClass(self, id, title='', REQUEST=None):
global CONTROL_PANEL
if CONTROL_PANEL is None:
CONTROL_PANEL = self.Control_Panel
self._setObject(id, MyClass(id, title))
...
class MyClass(...):
def __init__(self, id, title=''):
self.id = id
self.title = title
ob = CONTROL_PANEL.Products.MyProduct.MyClass('myId')
ob.id = 'myId'
self._setObject('myId', ob)
which works fine, until I need to use CONTROL_PANEL from somewhere else
before manage_addMyClass is called (currently, I am trying to upgrade
existing instances in __setstate__). Inside __setstate__,
self.Control_Panel throws an exception, for understandable reasons.
So, I get the feeling I am going about this incorrectly. I grep'd the
source last night, looking for a getApplicationInstance() method, or
something similar, but found nothing. AFAICT, there is no easy way to get
ahold of the one true Application object without having a reference to an
object in the ZODB and calling getPhysicalRoot().
Did I miss something? Is there a better way to do what I am trying to do?

a href="/path/script.pl/1234"1234/abr
a href="/path/script.pl/2345"2345/abr
Then, in script.pl, I would pick up the extra info on the other side from
$PATH_INFO.
The problem in Zope is that there is no "end" to the address. Serving from
Apache, it knows that the .pl extension is the end of the path. If there's a
'/' and more after it, it will push it to PATH_INFO. So how do you do this
in Zope? Because it's object names instead of paths in the request, how do
you send optional, additional info through the request as above?
You've answered your own question. There is no end in the middle of
the path. The publisher picks off each part of the URL from the top
down, and at each step, it asks that object if it can provide the next
one. Look at traverse() in lib/python/ZPublisher/BaseRequest.py, or
step through the publishing process - see
http://www.zope.org/Members/michel/HowTos/TheDebuggerIsYourFriend.
At each step, the publisher checks to see if the parent has the child
as an attribute, and if so, continues with the object at that
attribute as the parent (so long as other conditions are met, like
permissions).
You can see this in python products:
class Foo:
"a python product"
...
index_html = HTMLFile("someDTMLFile", globals())
index2_html = "HEADBODY..."
index3_html = aFunction(mood, phaseOfMoon)
Since getattr(path.to.foo, "index_html") reaches that html file,
ZPublisher.Zope("/path/to/foo/index_html") publishes that file.
index_html could be a (badly named) method instead, which has other
attributes. It could decide what to publish or how to allow
the publisher to traverse the path programmatically.
You don't need extra rules that look for foo.pl in the URL (what a
kluge - enforce a perl script to sit there until URLs are no more!).
For your example, script.pl could have two subobjects or other
attributes, 1234 and 2345, and the default index_html. Or script.pl
could be a ZClass with those three as DTML methods or other
subobjects.
__bobo_traverse__ is another attribute that the object may have to
drive the publishing process, but I haven't needed to understand why
it's useful yet :)

[Zope] 2.2.0 and Membership ... NoGo
Dunno what changed, but in 2.2.0b4 I could use Membership w/the latest ZPatterns just fine.

[Zope] I have a question on Zope 2.2
Hi everybody, I'm using Zope 2.2 on my local machine, where I constructed my data.fs, then after I uploaded this data.fs on my hurrah.com server which use an older version of Zope(2.1.6), then I was not able to add any DTML Document or DTML Method, and all the DTML images was broken, as well as at my web site all the pages was "not found" even if I was able to edit those file in the Zope management intereface. Anyone here know how to fix that ? If I cannot upgrade my zope on the hurrah.com server, how I can make the data.fs compatible with the older version.. ?

RE: [Zope] zope crawls - the day after
Uhm. Headers are headers, not content. As example, image files have headers too but no HTML inside. So you should set headers with RESPONSE.setHeader() i did set RESPONSE.setHeader(blah blah). my question was where should i put this statement. but now, i found out that it doesn't matter where i set it, it will be in the header. however, ie still doesn't respect the cache-control request. it till shows old news, which is bad, which brings me back to square one.:( i'm on my wits end now. help? hth Tino Wildenhain ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev ) ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
[Zope] Announcing dev.zope.org
Hello all, For some time now, it has been a goal of ours to open up the Zope development process. Some of you may have heard me promise this at the Zope track back in January. Well, it took a little longer than I had hoped it would, but I'm happy to announce an important step in making that a reality: http://dev.zope.org. dev.zope.org is the place for discovering, initiating, and contributing to work on the core Zope platform and related Zope technologies. You can think of it as the rough equivalent of what Mozilla.org is to Mozilla. Why has it taken so long? Because there is much more to "opening the development process" than simply doling out CVS access. Evolving a relatively large and complex piece of software like Zope is a non-trivial task, and doing it in a highly distributed environment is harder still. The dev.zope.org site will provide the background materials and tools to ensure that work on Zope is consistent in organization and execution. It will also help those new to Zope development to come up to speed and get involved quickly. There is still plenty to do be done on the site, but it is done enough to start using it so I want to start learning by doing. If you have questions or comments on the dev site, please send them to me at [EMAIL PROTECTED] and CC the zope-dev list (which is where I expect traffic related to dev.zope.org should go in the near term).
