[Zope-dev] Errors causing half rendered pages

2000-07-14 Thread Chris Withers

Hi,

I'm still debugging and writing the navtree code I've mentioned before
and I've noticed that not infrequently, when rendering a page that
causes and error, I get a half rendered page rather than a nice Zope
error page.

This is a bit waffly to put into the collector so I was wondering if
anyone else has had similar experiences?

cheers,

Chris

[Zope-dev] Namespace Questions

2000-07-14 Thread Adam Pawliuk



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

2000-07-14 Thread Steve Alexander

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

2000-07-14 Thread Chris Withers

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

2000-07-14 Thread Adam Karpierz

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.

Re: [Zope] how to check if the ResultSet is null?

2000-07-14 Thread Robert Wohlfahrt

Hi,

 Hi, I still got problems after I changed my code according to your 
 suggestion. Here is the detail describtion of my code:
 In registration form, I have a table which contain a field usr_email 
  (tr
 td width="40%" align="right"Email Addressnbsp; /td
 td width="60%"input type="text" name="usr_email" size="20"/td
   /tr)
   
 This form takes an action in which I have following lines:
 dtml-if search_membership
 pYour email address has been used. /p
 dtml-else
 dtml-call personinfo_insert
 h2Welcome dtml-var name="usr_fname"! You became a new user./h2 
 /dtml-if

Does it work, if you use the dtml-indtml-else/dtml-in construct
as follows:
dtml-in search_membership size=1
pYour email address has been used. /p
dtml-else
dtml-call personinfo_insert
h2Welcome dtml-var name="usr_fname"! You became a new
user./h2 
/dtml-in

If not, are you sure you inserted usr_email into the "Arguments"-field
of your sql-Method?

Re: [Zope] Variable sort in dtml-in

 I have attached appropriate patch for dtml-in tag for Zope 2.2.0b3/b4
 (Of course this patch was checked and works ok).

Thanks again for the patch.  It is a much needed option (and rather a glaring omission 
from

 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"

Is this necessary?  I actually use a variable for size (size=list_size) in the same 
dtml-in,
and that part seems to work just fine.  Maybe mine is a special case, but I don't 
think so.

 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.

I for one am for it.  The lack of multiple and variable sort keys in version 2.14 were 
a major
hindrance to me.  I am sure that many tags could benefit from similar improvements.

Thanks again,

Aaron

[Zope] HTML Editors that recognize DTML

2000-07-14 Thread Brad Moulton

Hello All,

as  a newbie I was wondering if those zope developers who use Linux 
have come across any HTML editors that support DTML tags
I note that the Windows developers prefer Homesite.

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. I cannot keep up
with all the Zope from the mailing list but am sure it will be very useful as I
progress along the path

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

 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.

 Hi,
 
 I've been working on a Python knowledge base for the last couple of
 months.
 
 http://python.faqts.com
 

Fiona:

This is a recent discovery for me - I quickly became a fan too. Thanks
for your efforts.

[snip]

 
 Basically I'm after some feedback, would this be of much interest?  I've
 had a couple of people write and request that I do this - what's the
 general consensus?

The only concern I would have is about fragmentation of effort (
and location of information). How can the community merge the best of
http://zdp.zope.org and http://www.faqts.com ?

[Zope] ZPygres connection problem

2000-07-14 Thread Oleg Broytmann

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

2000-07-14 Thread Brian Lloyd

 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.

Julio - 

I can't reproduce this here (using the Gadfly db connection
and DTML that looks like:

dtml-in getdata
dtml-var item_id, dtml-var item_name, dtml-var item_desc
br
/dtml-in

Can you tell me:

  o What db connection you are using

  o What the dtml of your in statement looks like

  o the permissions on the DTML method, the DB connection
and the SQLMethod you are calling

  o and the ownership settings of each of the above?

Thanks!

Re: [Zope] Weird problem with Z MySQL Connection

2000-07-14 Thread Jonathan

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

2000-07-14 Thread Brian Lloyd

 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] GUF KeyError problem

[Zope] suggestions for what to run in front of ZEO'ed zopes for failover?

2000-07-14 Thread Roman Milner


I'm wondering if anyone can suggest something good to run in front of
2 zopes talking to a zeo server - for failover and load balancing.  I
have been using a tool called 'balance' which works really well - but
for failover it only works if the socket to one of the zope servers
doesn't connect.

We occasionally have a situation where the socket will still answer
but the zope server hanges and never returns an answer.  So, I'm
looking for something with configurable timeouts on responses.  Does
any one know of anything like that?

Thanks,
^Roman

[Zope] Creating graphs with Zope (under NT)

[Zope] Zope 2.2 final released!

2000-07-14 Thread Brian Lloyd

Hi all,


  Zope 2.2.0 final has been released - you can download it 
  from Zope.org:

  http://www.zope.org/Products/Zope/2.2.0/


  Many thanks go to all of those who have worked with the 
  alpha and beta releases and helped work through the more 
  than 110 (!) issues that have been closed since Zope 2.1.6 
  came out.

  The Zope 2.2 release includes:

- The new security policy implementation and object ownership 
  that addresses the server-side trojan issue:

  http://www.zope.org/Members/jim/ZopeSecurity/ServerSideTrojan

- The new online help system which provides context-sensitive 
  help for all Zope management screens and includes Zope API 
  documentation

- A built-in Zope tutorial to get new users started with Zope

- Basic internal support for mountable object databases

- A new "history" tab for selected objects that provides access
  to previous revisions through the web

- Better performance on many systems as a result of setting a 
  more appropriate value for the "check interval" of the Python 
  runtime

- Many, many bugfixes!


  For more information on what is new in Zope 2.2, see the 
  CHANGES.txt and HISTORY.txt files for the release:

- http://www.zope.org/Products/Zope/2.2.0/CHANGES.txt

- http://www.zope.org/Products/Zope/2.2.0/HISTORY.txt


  Note that there are important changes to the security model in 
  Zope 2.2 that both site maintainers and Zope product developers 
  need to be aware of. Site maintainers should read the document 
  "Upgrading to Zope 2.2.0" for important information on upgrading 
  their Zope sites:

- http://www.zope.org/Products/Zope/2.2.0/upgrading_to_220

  Product authors should read the "Product author's guide to 
  Zope 2.2+ security" to learn about the changes in 2.2 that 
  may affect their products:

- http://www.zope.org/Documentation/How-To/ProductAuthorUpdateGuide

because use I use ZOPE  to access some really  simple databases.  I have NOT done any 
special python programming (but not for lack of trying) but would like some input on 
what I should say about ZOPE.  1) Is there a ZOPE demo for that runs on a CDROM?

I think you're looking for the "Zope on CDROM howto":

http://www.zope.org/Members/jens/news/zope_on_cdrom

 2) What is the best way to present ZOPE?

Hm.  In a bed of lettuce with an olive on top?
(sorry)

the advantages I noticed when first using zope:

Reduction of redundancy through aquisition (increases maintainability,
etc)
Easy dynamically generated pages (with or without RDB access)
Through the web management.

[Zope] Accessing the Application (or Control_Panel)

2000-07-14 Thread Jeff K. Hoffman

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?

 hi all
 
 zope is faster now.  i think i know why, just wanted some confirmation from the
 zopistas.
 
 setup:
 apache in front of zope on a rh 6.1 linux
 
 what happened:
 -got a lot of simultaneous connect in one time.  whe the number of connect
 exceeds 200, zope started slowing down.   and i mean really slow.
 -tried putting squid in front, still not much improvement.
 -set up cache headers again.  i did this earlier on, but was not successful.
 
 now:
 -got less then 100 simultaneous connect.  zope runs beautifully.
 
 what i think that solved this:
 -setting the cache headers.  at first, i put the headers in
 standard_html_header, before any html documents.  later, i put it after
 headtitle tags.  and i think i can see the cache headers on.

 so, i guess, it does matter where you put the cache headers.  is there a limit
 on how many simultaneous connect zope can handle?  apache ( i know it's
 different) can handle much higher traffic with not much complaints.

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()

 We occasionally have a situation where the socket will still answer
 but the zope server hanges and never returns an answer.  So, I'm
 looking for something with configurable timeouts on responses.  Does
 any one know of anything like that?


You didn't specify the platform, so I'll suggest a nice, cost-effective
one:
Linux with IPVS (IP Virtual Server). www.linux-ha.com has more

I believe that this will work fine.  There has even been discussion
of doing this (having a python base class to reference the classes
you want your ZClass to have as bases) as a good technique for dealing
with the fact that you can't change the bases of a ZClass after it
is created using the management interface.

[Zope] Delete property woes in ZClasses

2000-07-14 Thread Paul Abrams

I noticed that when you delete a property in a ZClass, it
doesn't actually delete the property in **instances** of
that ZClass! This leaves properties lying around where they
can be inadvertently acquired, causing problems that are
difficult to trace.

Has anyone gotten bitten by this, or know of a solution?

Cheers,
-Paul

Re: [Zope] (no subject)

2000-07-14 Thread Karl Anderson

"Leichtman, David J" [EMAIL PROTECTED] writes:

 I've previously been a Perl programmer. I did a lot of stuff where I would
 have multiple links with different options.
 Ex.
 
 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 :)

You could also delete the Catalog, delete the Item, and Undo the Catalog

[Zope] I have a question on Zope 2.2

2000-07-14 Thread Jonathan Desp

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.. ?

Very truly yours,

[Zope] Announcing dev.zope.org

2000-07-14 Thread Brian Lloyd

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).
