[Zope] Script (python) config

[Joseph Thomas (s)]

We upgraded from zope 2.9 to 2.10 and in the process upgraded plone as
well.  There's script that simply returns a list of groups to which a
user belongs. In the old system both users in the system and not in the
system (ie ids not in zope) would get HTTP 200 when invoking the script
thru a URL (obviously the non-system users would get an empty list)..

 

Now when system users invoke the script the script returns the list of
groups to which they belong, however, when a user not in the system
invokes the script it returns a 401. Is there some
authentication/security setting that we're missing that's preventing
non-system users invoking the script? We may have overlooked some small
thing (file system permissions, ZMI permissions, authentication settings
etc) when configuring things in the upgraded environmentany ideas
would help.

 

Thanks

Re: [Zope] sending a encrypted login URL

[Joseph Thomas (s)]

Thanks, could you elaborate a bit, I'm somewhat new zope/plone:

I assume we'd need a shared key on both on ore j2ee server and zope, and
did you need to create any changes to Plone PAS?

We are doing this using the Python package "M2Crypto.EVP"
for the encryption/decryption.

[Zope] FW: sending a encrypted login URL

Subject: RE: [Zope] sending a encrypted login URL

I think I get what you're suggesting, but let me clarify.

I actually wanted the sensitive portions of URL to be encrypted..because it 
will be link on a page that says "login to zope"..but I wouldn't want the user 
or a snooper to be able to view the page source and figure out the URL pattern 
and the username/password.

SSL will ensure that the transport between the browser and the zope server will 
be encrypted using PKI, but I really want to obfuscate the user name and 
password parameters in the login URL. So that that if some1 where to view the 
source they'd see  garbled username/password parameters.

I suppose I could use the PKI to encrypt the username/password with my zope 
server's public key (but is there a API to do this on a J2EE container) and 
then have my zope server decrypt using its private key (but how would zope know 
that the username/password parameters are 2 be treated as encrypted data)?

[Zope] sending a encrypted login URL

[Joseph Thomas (s)]

We'd like to construct a zope login URL of the form on another server:

 

http://zope.domain:port/context/logged_in?__ac_name=uzz&__ac_passwor
d=xxx&submit=Log+in

 

 

where the ac_name and ac_password parameters are encrypted using zope
public key (?) and have the parameters decrypted when zope receives the
request and login the user.

 

Is there an API or some way to encrypt the username and password on the
3rd party app server and configure zope so that it treats the parameters
as encrypted values rather than plaintext?

I recently installed plone from plone.org, just curious what's the
difference between the python installation that's bundle with plone

Its not zope perse, but Plone that we're customizing. I may be able to sell 
zope 3/Grok etc but it all hinges on plone support on the underlying app server 
or framework. Is plone ready to run on Grok?

Agreed, if you are going through the learning curve anyway, may as well be the 
new way.  Grok, in fact, may take less time to get into for basic apps.

If you are new to Zope and/or interested in Zope, you are possibly more

[Zope] Please Help - Extracting Info From ZEXP File

[s]

I just took over a website that was done in Zope/Plone. The person formerly
responsible for it was not helpful to the client or me in the transition
process. Basically he emailed a ZEXP file to me, told me it contains
everything I need, and washed his hands of the whole project. I was able to
"grab" nearly all the html, css, and javascript files through the web before
he removed the site from his server, but now I realize a few pages were
missed. So, it seems the only possibility of restoring those missed pages is
if 1) everything really is in that ZEXP file and 2) I can find a way to "get
to it." I know nothing about Zope/Plone and, no offense to anyone, do not
plan on adding it to my repertoire of knowledge in the near future. I just
want the "normal" HTML content as it would've been displayed for these
certain pages that were not grabbed before he removed the site. Is this
possible? If so, could someone please spell out exactly how I can go about
retrieving this information from the ZEXP file?

[Zope] Description Strings in Archetypes

[S . D .]

I'm running Archetypes 1.3.2-final in Plone 2.0.5 (Mac OS X Server). I added the
Article example from ArchExamples to the available items list in a Plone site.
It works fine except for the fact that when you look at a list of Articles
inside a given folder, each item's Description is taken from the Description
string of the containing folder rather than the Description attached to that
individual Article.

For example, if I create a folder named "Foo" whose Description field reads
"Place your foo in this folder," that description is attached to each of the
Articles you see when you look at the folder listing.

Apparently, the Description info is being taken from the wrong "Description."
How can I adjust Archetypes to find and display the correct, Article-specific
Description?

Thanks!

Scott

I'm a bit concerned about my perception of Zope 3's flux.  I was especially
dismayed to see, in the Z3 book,
---
 Zope 3 will come with an advanced ZODB to Filesystem synchronization tool,
similar to CVS. This will allow people to make local copies of their sites
work on it and check in the changes and much more. This recipe will explain
how to effectively use this tool.

Note: This chapter will not be included in the first version of the book,
since Zope X3 3.0.0 will not ship with it and it is not actively maintained
at this point.

The first paragraph was great.  The second wasn't :)

We're porting a web application to manage a collection of DNS and DHCP
servers.  At startup time, we talk to each of these DNS and DHCP servers to
ask them what zones they know about (in the case of the DNS servers) and
what pools of addresses they use (in the case of the DHCP servers).  This
information changes rarely, and costs some time to acquire.  

Actually having said this just now, I'd say a better solution for us would
be to actually initialize an object when the user logs in -- we can
tolerate that delay, and that gives us a relatively fresh snapshot of the
current situation.  Don't know how that changes things.  It feels like it
should make it easier.

Hmm.  I'd be willing to use Z3, I think -- I haven't done Zope development
for about 6-9 months, but all my previous experience has been on 2.x.  The
other people involved in this are all brand new to Zope.  Why should I use
Z3? Does it have better documentation? :)

Excellent.  It looks like persistence may not be an issue here, actually,
since I think the persistence I want -- hang around for the life of the
Zope server -- is built in anyway, right?

So what's a decent source these days for 'how to write a product'
documentation? The Zope Developers Guide is in 2.4.

Ah, sorry.  In this case, it's persistent for the life of the server, so we
expect to re-initialize it when Zope restarts.  Oh, and it'd be nice to
give it a .reinit() capability too, if the user wants to refresh :)

[Zope] Persistent Objects

[Roy S. Rapoport]

A coworker of mine wrote his own web server framework from scratch for an
internal application.  We're looking to migrate this application to Zope
(thank God!).  The only question we need to deal with is:  

The reason he wrote his own webserver rather than use CGIs is that there
was some processing that needed to happen to initialize a system state --
basically, create an object that knows about the configuration of some
things.  In his model, this object is created at the beginning and is
simply shared among the various Python objects/modules that are invoked when
responding to user requests.

How can I create such a persistent object that, say, a python script object
or a page template could access?

(Sure, handholding on this would be nice, but what I'm actually expecting
is answers along the lines of "look into ")

[Zope] ZClass authorization problem (You are not authorized to access manage_changeProperties)

[Gaspard, Bradley S]

I have created a new ZClass which contains a dtml method that first clones
an object and then edits it's properties:





When I fill out the 'add' form and try to create a new instance I am
presented with the error message (as a user with
a manager role):

You are not authorized to access manage_changeProperties

I am able to successfully create an instance if I am the superuser.

How do I fix this??

[Zope] Newbe external method question

[Gaspard, Bradley S]

I have what I fear is a very basic question ... 

I want to write an external method that first determines all of the objects
in a folder that posses a certain property.
I know how to find the object ids but once I do that how do I then determine
which contain the property I am searching for??

Thanks for any help.

Brad

[Zope] Using MySQL with ODBC causes re-authentification of Zope on WIN2000

[Richard S Herrington]

Here is a perplexing problem I am experiencing.  First, I was able to
compile the MySQL database adapter (MySQLdb) for WIN2000 and connect
successfully to a database I set up on Windows.  I set up a ZSQL method to
return rows from the database.  Then I set up a DTML method to iterate
over the rows and fill a html page using "dtml-in" to receive records from
the ZSQL method:

...snip...snip...




...snip...snip

This worked fine.  Next, I was able to connect with a MicroSoft Access
database using an ODBC method.  Then I did the same as before.  Create a
ZSQL method (e.g. sqlQuery), then iterate over these rows with a "dtml-in"
tag, filling an html page.

Now here's my problem.  When I set up a MySQL ODBC connection.  The ZSQL
method by itself returns rows from the database just fine.  However when I
access the index_html page that contains the "dtml-in" tags.it causes
a prompt to reauthenticate to Zope (username and password).  No known
username and password will work.  I set all my MySQL permissions properly
as far as I know.

I've scoured the archvies but have found nothing.  I need some leads as to
what to try.  Thanks in advance.

[Zope] Adding an XMLDocument instance Programmatically

[Gaspard, Bradley S]

I am trying to write a python method which will programmatically create an
instance of an (existing) XML document.  (I am using Zope2.1.6 and
XMLDocument 1.0a6)  I am able to add an XML document by selecting the
XMLDocument from the available objects ... so XMLDocument is installed
correctly.

Essentially I have taken the 'add' method of XMLDocument and tried to turn
it into an external method.  [I was able to successfully do this for the
Parrot product so hopfully I am on the right track]

I can' t seem to get beyond importing Document (cannot import name
Document).  Do I need to import other modules?  Is this the best/only way to
do this??  Appreciate any help.

from Products.XMLDocument import Document

def add(self, id, title='', file='', REQUEST=None, submit=None):
"""
Add a XML Document object with the contents of file.
"""
ob=Document()
ob.title=title
ob.id=id
if file: ob.parse(file)
id=self._setObject(id, ob)
if REQUEST is not None:
try: u=self.DestinationURL()
except: u=REQUEST['URL1']
if submit==" Add and Edit ": u="%s/%s" % (u,quote(id))
REQUEST.RESPONSE.redirect(u+'/manage_main')
return ''

I appologize in advance if I have missed something obvious.

Brad

Re: [Zope] Manager Screen Authenication

[Sean S. Rowe]

Still not working.  I am using version 2.1.6 and compiled using 'python -O
wo_pcgi.py'.  In addition, the QuickStart guide works, which seems to use
Zope.

Is it possible Apache is somehow handling the request and I need to direct
it to pass authentication variables?

Thanks,

Sean.

[Zope] Manager Screen Authenication

[Sean S. Rowe]

Hello.
 
I'm new to Zope and have just installed it on a 
server running BSD.  I built the source and everything went fine.  I 
went to localhost:8080 bypassing Apache and the welcome screen came up as it was 
supposed to.
 
However, I cannot logon to the manage section of 
Zope.  My password is always wrong.  I changed my password with the 
following: 'python zpasswd.pyo -p new_password access'.  Nothing I do seems 
to work and the only info I can find is on running with Apache not 
Zserver.  Any help would be greatly appreciated.
 
Thank you,

[Zope] Newbe question concerning using python classes and external methods

[Gaspard, Bradley S]

All,

I am a new Zope user and I guess I'm missing something fundemental that I
haven't been able to glean from the documentation and various "How-to's".
As a learning tool I am trying to implement one of Brian Lloyd's examples I
found on the Web implementing a GuestBook.  

I suspect what I don't understand is how to write the external method that
would make use of this class (The one I have been playing with follows the
class definitions).  Anyhow, I've created an an external method and call
(e.g. ) after which the guestBookForm is displayed.  After
filling out the form and submitting it Zope does not seem able to find the
signGuestBook method.  What am I doing wrong??

Other than mostly trivial examples, I haven't been able to find many
complete (working) examples of using external methods.

Thanks in advance for any help.


"""Module guestbook: a simple guestbook application"""

class GuestBook:
  """A guestbook object that provides both the forms
 and the handling of submitted form data."""

  def __init__(self, title, filename):
self.title=title
self.filename=filename

  def guestbookForm(self):
"""Return the guestbook from to the user"""
return """
  %s
  
  %s
  Please sign our guestbook!
  
  
  Name: 
  Email: 
  
  
  
  """ % (self.title, self.title)

  def successPage(self):
"""Return a page to thank the user on success"""
return """
  %s
  
  Thank You!
  Thank you for signing %s!
  
  """ % (self.title, self.title)

  def signGuestBook(self, name, email='not specified'):
"""Handle a submitted guestbook form"""

# Open a file to save the guestbook entry
try: 
  file=open(self.filename, 'a')
except IOError:
  file=open(self.filename, 'w')
entry='Guestbook entry: %s %s\n' % (name, email)
file.write(entry)
file.close()
return self.successPage()





External method

import sys
sys.path.append('/usr/local/src/Zope-2.1.6-linux2-x86/lib/python/Shard/jscap
e/winsat')

import guestbook

def AddGuest(self):
  myGuestBook=guestbook.GuestBook('My GuestBook', 'guestbookdata.txt')
  return myGuestBook.guestbookForm()
