*Ahem* Actually, Membership *does* provide login/logout forms that do 
not require accessing a private section of a site.

Ok, that's different.

Dead Simple way(tm):
Make page that *does* have a need for login. Put a link to it, call the 
link "login".
When they access the page, they wil not have permission to see it, and 
will thus be given a request for authentication, the logging them in part.

If you put this method in the root of your site, say calling it 'login' 
for an id, then you could put a link in your menuing system that calls 
it with an href of "login".

Then, in your 'login' method/page, you set it up to redirect back to the 
page they were on when they clicked the login link. There are several 
examples of this part around; search the Mailing List(s) archives.

Until such time as they do log in, the user will be 'Anonymous'. As 
such, you would make the appearance of the login link dependant on the 
AUTHENTICAT_USER having the Role 'Anonymous'.

Without using a cookie login system, you _must_ access a restricted 
resource, even if it just a redirect. That is how basic Authentication 
works. If you are using cookie login, there are HowTos on that around as 
well. You just show the user the login page.

Someone repeats the HEAD HTTP request.

Look at the Apache log. You should see there similar requests.
The first component in each log line is the the hostname or
its internet address from where the request came (may be a proxy).
Maybe, this information gives you a hint about the
requests origin.

[Zope] newbie q -- 2.3.0a1, file object & precondition

[John Gerard Malecki]

hi,

i'm very new to zope and am trying to get familiar with the variety of
mechanisms i can use.  zope is indeed a very nice package!

i am starting with version 2.3.0a1 (because it matches the book).
i've not yet had success getting preconditions to work with file
objects.  i hope i'm not doing anything too bone-headed.

here is what i have: in a folder i have file objects T and U.  T has
the precondition 'preco(1)' and U has the precondition 'preco(0)'.  in
the same folder (or above, it doesn't matter) i have the python script
preco with the contents

if r == 0:
raise "preco"
else:
return r

when i the manager or type in the URL directly i can view/download
both T and U.  i was hoping only T would be "visible".  

i'm not sure how to debug something like this.  if you can tell me how
i can debug this on my own that would be best.

-cheers

Ronald L. Roeber writes:

"manage_editProperties" has the following signature:

def manage_editProperties(self, REQUEST)

As you see, there is indeed no parameter named "contact".

You can do instead:

  self.manage_editProperties({'contact' : newcontact})

This means, you build a dictionary with the new property
values and pass it as REQUEST.


Be WARNED:

   "manage_editProperties" changes *ALL* properties
   of your object, even those not mentioned in the
   dictionary!

What you may want to use instead is "manage_changeProperties".
It will change just the mentioned properties, 'contact'
in your example.


I think, you find this information in the Zope integrated
help system (API Reference, Property Manager).
If not, then look at the source: OFS.PropertyManager.PropertyManager.
It contains good source documentation.

would do it, but would be *VERY* hacky code.

Instead:
   Give your method a parameter, say "sourcefolder".
   In your method:

  
   
   (You may want to factor the "(_.has_keyPARENT[0])" out.)

   Then, when your method should use a special folder, use:

The error report is unambiguous.

Your "REQUEST.form" does not contain "SERVER_NAME".
You may try "REQUEST['SERVER_NAME']".

Remember:
   "REQUEST.form" contains just the form variable or
   parameter definitions in the URL's query string.

   "REQUEST" contains other information in
   "REQUEST.cookies", "REQUEST.other" and
   "REQUEST.environ", all of which are
   accessible through "REQUEST[...]".

   "SERVER_NAME" is a CGI variable, defined in
   "REQUEST.environ".

[Zope] emacs and zope

[Mehmet Yousouf]

Hi,
I am trying to get xemacs to use dtml tags (zope), I downloaded .dtd,
.ent, .el files and can get it to go into "dtml-mode", but I can't get any
of the tags to appear in the menus. I put the files in ~/Emacs/ (this is
referenced in my .emacs file) it seems to find my public file, and the .el
file as I do get into "dtml-mode". I tried putting the .dtd and .ent files
in /usr/lib/xemacs/xemacs-packages/etc/psgml but still no luck.
What am I doing wrong?

Regards, Mehmet

[Zope] PoPy Problems

[J. Atwood]

Linux 6.2, Zope 2.2.4, PostgreSQL 7.0.3, PoPy 1.4.1, ZPoPyDA 0.7.0

I installed the PoPy module and at the Python command line can 
"import PoPy' with no problems. I then untarred the ZPoPyDA and 
restarted Zope at which point I get (in the Zope management screen).

ZPoPyDA Import Traceback

Traceback (innermost last):
   File "/usr/local/zope/lib/python/OFS/Application.py", line 397, in

   File "/usr/local/zope/lib/python/Products/ZPoPyDA/DA.py", line 35, in ?

   File "/usr/local/zope/lib/python/Products/ZPoPyDA/PoPy_db.py", line 35, in ?
 raise "The PoPy module is not installed"
The PoPy module is not installed

There is really no more instructions on the site, in the INSTALL or README.

If have installed and worked with ZPygreSQL before but was under the 
impression that it did not work with the newer versions of Zope and 
Postgresql.

Thanks,

Re: [Zope] zope on Win95

[Jason Cunliffe]

Nando

This should be what you are looking for:

http://www.zope.org/Products/Zope/2.2.4/Zope-2.2.4-win32-x86.exe/view

I have been running Zope on Win95 and Win98 on laptops for learning,
development and off-line site demsontration very happily for a long time.

You don't 'execute dtml files' ... Zope uses them for many purposes as
server-side scripts which are rendered and returned as ordinary HTML in the
client web browser. DTML files can combine Zope-specific syntax, Python
sytnax, Javascript stuff, CSS etc.

Learning how to design for Zope, factoring the application, when and where
to use the many tools and techniques - it takes time and practice to do
well. But it is possible to get simple but impressive results very fast.

DTML can be called within other DTML, Python or directly in a URL from a web
browser.
For example: http://www.myzopesite.com/invent
'invent' might be one of many things including:
- a DTML Document or Method
- some other script or method typically programmed in Python and accessible
to Zope
- a Zope other object in the ZODB [Zope Object Data Base]
- a Zope 'folder' which appears as a hierarchical file system tree of
containers for Zope applications, projects and data


1. See the online version of the new Zope Book
http://www.zope.org/Members/michel/ZB/
This will be published very soon by O'Reilly

2. Run through the tutuorials which are included when you download Zope.

3. See many more guides, how-to's etc are linked from
http://www.zope.org/Documentation

Good luck!

[Zope] SELECT COUNT(*) ZSQL method -> displaying results?

[Lee]

Hi,

I am having difficulty displaying the results from an SQL query:

SELECT COUNT(*)
FROM REGISTRY
WHERE 

When I call the ZSQL method from my DTML method and try and display the
result (using ) I get a rather horid, "This resource may
be trying to reference a nonexistent object or variable count" error.

My only thought is that because 'count' isn't actually a proper variable
(i.e. a column name) it is handled differently.

Can anyone see my error / offer advice?

Thanks very much in advance.

Lee

You mean you want to use AUTHENTICATED_USER like a cookie, i.e.
loggin in and every password authenticates?
Using basic auth it might be a nice way to get cookie functionality
without using cookies.
You could write a custum method which triggers authentication and
rewrite the method of GUF to always return 1. If someone wants
to "log in", he could click on a link to this method. 
Maybe



Logout!!


You are now logged out!

could be a starting  point. If it is contained in standard_html_header it
would force everyone to choose a user name, and in conjuction with
the GUF-hack mentioned above he would always be logged in - 
well unless he decides to call himself "Anonymous User" (luck that
this isn't coward ;).

If you want to use cookies anyways, take a look at session manager or
code it yourself and don't use hasrole.

cheers,
oliver

[Zope] UserFolder Alternate Login

[dlee]

Zopatistas,

I need functionality that none of the UserManagers seem to address. I 
need to allow a user to elect to log in (and set 
AUTHENTICATED_USER) as opposed to have them access a restricted 
resource to trigger cookie authentication. 

I am essentially limited to GUF because it's the only thing I can install 
on my provider's system (I can't compile the LoginManager). Is there 
a way to allow the user to login at will, and still get 
AUTHENTICATED_USER set?

There are no "restricted" parts of the site I am building (except for the 
management interface) however, I would like to generate dynamic 
menus (using hasrole) which allow users in specific groups (authors, 
members, etc) to have additional menu options.

I'm hoping there is a way to do this...

Thanks in advance,
Darin Lee

I have looked through the Zope book and other documentation, but still

Case in point, a product with a Property called

contact
which is a string

The product changing method  I am trying to make work contains the
following

def editProductInfo(self, newcontact):
 ...
 self.manage_editProperties(REQUEST=None,contact=newcontact)
 ...

Which is not correct obiously since it generates the following error:

  I'm quite happy, got MySQL + the necessary adapters running in no 
time. Imported tab-delimited text and enjoying Zsearches... Zope 
kicks ass!

  Now, i'm wondering if there's anyone who've done some work as to 
permit easy editing of records in SQL tables? What i have in kind is 
something like:

  - do a search -> a list of matches come up;
  - select a match -> a form comes up filled with the data, and a 
"submit" button
  - press submit -> SQL gets altered

  A bit like the "edit this page" philosophy, but for SQL records...

  Thanks!

Alex.

[Zope] Pb. of Inheritance lost between packages. (after too manyexport/imports ?)export/imports ?)

[Thierry Nabeth]

Hello,

Here is this problem again that has reappeared  
I already posted about this problem some months ago,
but did not manage to make it work, and I had to rewrite
all the class from scratch.
(of course, I did a lot of cut and past, but you
have to do a lot of manual work recreating the
Properties, and you loose all the instance you had created).

Here is my problem: 

I have 3 Products PA PB PC
and I have the 3 classes A, B and C defined in each of the
different Products.

PA has class A
PB has class B
PC has class C.

Besides, the inheritence tree is the following:

A <-- B  <-- C.
(A inherits from B, etc.)

The problem is that after some time (after many export and re-import of
Products),
the inheritance does not work anymore between the package.

For instance if I define a new method in class A,
it is invisible from class B.
Or if I redefine a method in a Class A, the class B still 
see the old method of class B.

Note that at the beginning, when you create those three packages
and classes, everything seems to work fine.
(I have done the test).

Did someone already encountered a similar problems ?
Do someone has an idea what could be wrong, and has some idea about
how to fix the problem ? 
(my guess is that something wrong happens after too many
export and imports which confuses python).

[Zope] Z2 Log question

[Stuart Foster]

I was looking at my Z2 log and notice an entry that repeats itself over 
and over and was wondering if anyone could tell me how to trace it down.

The message is

 [20/Nov/2000:13:00:11 -0700] "HEAD /opnix/portal HTTP/1.0" 401 1906 "" 
"" 
 [20/Nov/2000:13:00:17 -0700] "HEAD /opnix/portal HTTP/1.0" 401 1906 "" 
"" 

and as you can see it happens about every 5-6 seconds and there are many 
entries for it. 

Where would I start to back track this. 
We are running Zope behind Apache using proxy pass.

Any thoughts.

TIA Stuart

Re: [Zope] How to split a string in a python method?

[Jim Washington]

Yes. Just use it. string is already in the Python Methods namespace.

EXAMPLE:

Python Method 

Parameter list: self

Python function body:

testsentence = 'I want this sentence to be converted into a list of its
component words.'
thelist = string.split(testsentence)
for aword in thelist:
  print aword
return printed

Oleg,

what might come handy in your case is the howto "Shane's Aquisition

 http://www.zope.org/Members/chrisw/showaq

it'll help you visualize the acquisition path from your document.

You may also want to look at my howto Changing Contexts in Zope

use attached xmlio.py (put it in $ZOPE_HOME/lib/python/Shared)
you don't have to use the makefile. just untar the tarball into
$ZOPE_HOME. (i use the makefile when i develop to automatically

Re: [Zope] Acquisition: DTML Methods vs Documents

[Dario Lopez-Kästen]

Hello!

I think hade a similar problem. It seems that you can only use methods for
acquisition, not documents.

I had an index_html DOC where I specified the structure of my site. In
index_html I used  that and in some_doc I once .

The idea was that in my subfolers I only needed to have the objects some_doc
and other_doc, and that I would use the structure from the index_html higher
up. This way I could provide "modules" to managers of subfolders, so they
need not to concern themselvs with the proper way of setting up their
index_html.

It didn't work unitl I changed index_html and all other objects from
dtml-docs to dtml-methods. Otherwise I would always end up with the parent
(in my case the root level) documents. I wanted to have DTML-documents in
the firts place, because I noticed that in dtml-methods the  call has no effect; it does not use the methods title_or_id, it
uses the toplevel (or the calling documents) title_or_id.

Is this a similar situation to yours?

Because not all documents are acquired (from an above folder). For index_html, for 
instance, it is common to have a different index_html (and in that case a document) in 
each folder.

Try...

  v should contain the value

Otherwise...

Hope that helps.

Actually, if I understand it myself :-) it acquires foobar because a method

In that case, you start the acquisition with the document index_html (reread

the acquisition can start from a document or a folder, not from a method).

You started acquisition from index_html. Since it has no foobar, it looked 
into its own container, /TEST, then in root.

You can but the "problem" in your case, comes from the acquisition of an index_html 
document in a different folder. I suggest to add index_html documents in every folder 
*or* make index_html a method (this is what I use).

   Exactly as I wrote - in this situation standard_html_header acquires
using static path provided by index_html :(

   There are many Documents on my site, not only index_html. Should I make
them all Methods? Why after this I need Documents at all?

   If I call http://machine:port/top/middle/AFolder/ADocument (in terms of

[Zope] Acquisition: DTML Methods vs Documents

[Oleg Broytmann]

Hello!

   Can anyone here explain clearly what is the difference between DTML
Methods and DTML Documents regarding acquisition?

   Well, in simple cases I think I understand it. When I call a Method
through the web, it use dynamic (based on current URL) acquisition path. A
Document uses static (based on its position in ZODB) path.

   But what if I want to look a bit deeper? What are acquision paths for a
Method called from a Document, not directly from the web? I beleive when a
Document called from a Method it always uses static acquisition path. But
what about a Method called from a Document? It seems my Methods stopped
using dynamic paths and use static paths, provided by its callee. Right?

   Let's see a running demo. The site http://phd.russ.ru/pcgi/TEST/
constructed as follows:

/TEST - folder
   index_html - standard DTML Document with default content
   standard_html_header - DTML Method
   standard_html_footer - DTML Method
   2 - folder, empty

Both folders /TEST and /TEST/2 have a property "foobar". In /TEST its value
is "First test!", in /TEST/2 - "This is SECOND test." standard_html_header
show the property with .

   When I call standard_html_header directly through the web, it acquires
foobar using dynamic acquisition path:

http://phd.russ.ru/pcgi/TEST/standard_html_header
   show foobar from root (/TEST)
http://phd.russ.ru/pcgi/TEST/2/standard_html_header
   show foobar from /TEST/2

But then I call standard_html_header from DTML Document index_html:

http://phd.russ.ru/pcgi/TEST/index_html
   show foobar from root (/TEST); exactly as I expected, no problem
http://phd.russ.ru/pcgi/TEST/2/index_html
   WOW! It show foobar again from root, not from /TEST/2!
standard_html_header acquires using static path provided by index_html!

   Is it normal and intended behaviour? If it is, how can I "solve" my
problem? (I want to acquire different properties in standard_html_header,
but call standard_html_header from different DTML Documents).

Oleg.

you need to make sure you create a table with a SERIAL type, which
automatically create phrases_phrase_id_seq table (which is why it should
be called phrase_id in your case).

These are normally created for you, but, if you drop the table, it
doesn't automatically drop the sequence table. You might have to drop
the table and the sequence and re-create your table so you get the
correct table setup. Postgres can be a complete pain at times.
