[Zope] Still need help about Product namespace
Hi,
I still need help about my product needing to know its namespace...
Look at the following piece of DTML Meth/Doc :
dtml-let STRING="'Hello, world !'"
dtml-var MyProduct
/dtml-let
Right.
MyProduct is my product's instance, defining the following method :
def __call__ (self, REQUEST=None):
if REQUEST is None:
if kw: REQUEST=kw
else:
if hasattr(self, 'REQUEST'): REQUEST=self.REQUEST
else: REQUEST={}
print STRING
This raises a key error.
I MUST get the STRING variable from the '_' namespace, but how can I
pass IMPLICITLY this namespace to my product ???
Is there a way to acquire _ ???
Many thanks,
P.-J.

[Zope] REQUEST.set size
Hi all,
I am new to Zope but worked for 2 years in a dev-env called Uniface so
Im fairly up to speed on Zope quickly. But I am having a problem writing
data through a REQUEST.set that is larger than its apparent limit.
(sorry can remember the exact error i get from Zope)
What I am trying to do is collect in a field a large list of emails that
are gathered in a dtml-in statement with a REQUEST.set('all', all +
email) nested in the loop. While appending the namespace to store the
data in PGSQL, i always get the size error which i assume is coming from
the publisher saying that a the request can only have a byte size of
1800 bytes or so.
Im not so hot with straight SQL because Uniface had its own methods, so
Im not sure if I can append data directly to a stored field or if I need
to continue trying to use the REQUEST.set. After the hundreth occurence
in the IN, the namespace I use to store the appended data, so I cannot
fully make a list of 2000 occurences. Any ideas?
Sorry, no code to show what Im doing but it should be pretty easy to
understand for all you veterans out there...

Re: [Zope] cookies don't obey me
Roland Reumerman writes:
1) When I set a cookie with the path set to the root
dtml-call "RESPONSE.setCookie('account',AUTHENTICATED_USER,path='/')"
Be careful with "cookies"!
The value of a cookie it quite severely restricted (must not contain
many characters; you read the cookie specification?).
In your case, the value is not a string at all but a
Zope object. "RESPONSE.setCookie" will probably convert the
object to a string for you. This will give you
"AUTHENTICATED_USER.getUsername()". However, I would feel
better, if this would be in your "setCookie" call.
Note, that probably Zope user names may contain characters not
allowed in Cookie values.
I'm still not able to click through to another hyperlink once I'm logged in,
i.e., I've used www.ddi.nl/support to go the password protected Zope site,
logged in as a customer, and from there I can choose other parts of the site
(below .../support/). However, www.ddi.nl is an alias of
www.datadistilleries.com (the actual name): as a result it asks me for the
password again. I thought setting the path to '/' would convince Zope I'm
authorized, but apparently it's not the case.
The path is a "local" path on your server.
Setting "path='/'" tells the browser to add the cookie to
any request going to your server. "path='/'" would tell
the browser to send it only for requests with paths beginning
with "/".
You cannot control with "path" to what server the cookie is
sent. There is the "domain" specification that gives you
some control over the servers that get the cookie.
I doubt, however, that this mechanism will allow you to
send cookies defined by "www.ddi.nl" also to
"www.datadistilleries.com".
2) This might be related to 1. I've created a logout link on the
/support/index_html page, which looks as follows:
dtml-call "RESPONSE.expireCookie('account',path='/')"
dtml-call
"RESPONSE.redirect('http://www.datadistilleries.com/support.html?section=m6envelope=6')"
However, once I've been redirected I can still access the password protected
/support/ site without Zope asking me for a login name.
There must be some magic, you did not yet tell us about.
Usually, setting a cookie has nothing to do with password
protection or authentication.
There must be something like a "login manager" that ties
Zope's security subsystem, login/logout and cookies together.
Usually, this "login manager" would do the cookie handling
transparently.
That you are concerned with the cookie seems to indicate
that you implement your own "login manager"?
The built in Zope authentication does not use cookies at all
but "basic authentication" as defined by HTTP.

I need the branches to represent two different meta types, Album and Photo.

RE: [Zope] overriding __str__ method?
Seb Bacon writes:
I know how to create a form that does what I want (update properties,
whatever). What I don't know is how to include it as part of the rendered
content programmatically. At the moment users have to go to
www.widgets.com/manage_content, log in, and see a set of forms loosely based
on the Zope manage interface. Instead, I'd like them to go to the same url,
and see exactly the same website as someone who's not logged in, except they
have these lovely little "edit this" buttons next to each editable content
element (by which I mean image, text snippet, etc).
Now I *could* do a
dtml-if "AUTHENTICATED_USER.has_role('content manager')"
a href="edit_this"edit this/a
/dtml-if
in each content element. But I'd much rather be able to subclass or mixin an
'editable' class for each content element in question. The question is,
what methods should I be providing to manipulate how the content is
rendered? For example, I can provide a new 'view' method in the 'views' tab
for a ZClass, but this does not get called when an object is rendered as
part of another document. The reason I was going on about __str__ is
because that seems to be the only place that you can interfere with how the
content is rendered inline?
Hope that's clearer,
I now do understand it better. Though, I have to admit that others
understand you first problem statement better than I did.
DTML renders an object by
1. looking it up
2. calling it, if it is callable
3. stringifying the result by calling "str"
Thus, for callable objects, changing the "__str__" will not help.
For callable objects, "__call__" would need to be modified.
However, I would strongly discourage to make such a drastic change
to Zope objects:
* a modification of "__call__" would not only affect rendering
but also other use of objects (e.g. if DTML methods
are used to validation and should return "0" or "1".
* the pages could be littered with "edit me" buttons.
It is (in general) not easy for your content manager
to determine the object boundary which the "edit me"
applies to.
* we use DTML objects sometimes to factor out common
"object"s such as e.g. the option list for HTML select
tags. Automatically adding "edit me" would produce
invalid HTML.
I would rather suggest, you develop some method (or product), say
"content_render", that can render an object (emulation the
normal DTML rendering process) and can add whatever is necessary
to facilitate management (e.g. visualizing object boundaries,
placing "edit me").
Rather than
dtml-var xxx
you would then use
dtml-var "content_render(xxx,_)"
at places where the result would be usefull and legal (e.g. not inside a
"select" tag).
Have you looked at the PTK?
You will find there some of your idea realized. However in a
simplified form: a document contains a single "edit me" integrated
to allow the owner to edit his content.

[Zope] (no subject)
Chris Withers writes: Toby Dickenson wrote: Those people were concerned that too many things were exposed via ZPublisher also My interpretation was that the issue is one of access control, not publishing protocol. I think the issue is that you can't limit the visibility of objects right now. but there doesn't appear to be any easy way to say "right, I want this object exposed for reading and writing via FTP and reading via HTTP, while this one shouldn't be URL traversable but I'd like to edit it via WebDAV and this method is for use via XML-RPC but really shouldn't be visible anywhere else.) I agree with Toby: Unless there are drastic differences in capabilities for protocols, we should focus on access/visibility independent of protocol. To get a feeling what I mean with drastic differences: When SOAP access would allow me to "attack" (hack, espionage, steal, or whatever) a Zope site in some minutes when the same attack would take years via HTTP, then we should be concerned with protocol specific forms of restrictions. However, as Toby pointed out, up to now I can do as bad things via HTTP as I can do with any other protocols. This is because the thing which makes the problem hard is that something like standard_html_header wants to be editable by Managers TTW, which means it also has to be visible TTW. However, it's probably not something you want exposed to anonymous users, especially as a TTW enitity in its own right. objectIds is my other favourite example ;-) I think, this could be easily achieved: * provide a "version" of "objectIds" that filters according to authorization. It would return the list of id's for objects I am allowed to see. * This would not yet cover the case of "standard_html_header" and other presentation "components" (that should not generally be seen as independent entities). To handle this case, a different permission would be necessary to distinguish between TTW use and use from inside the presentation machinery (DTML, Templates, whatever). An "URL traversable" permission, as suggested by Chris, seems to fit the bill.

[Zope] Namespace within a product... (argh...)
Well, beeing very straightforward, I read this, in
OSFP/Help/DTMLDocument.py :
"""
A DTMLDocument implicitly pass itself as a client argument in
addition to the specified client, so names are looked up in
the DTMLDocument itself.
Passing in a namespace to a DTML Document is often referred to
as providing the Document with a *context*.
DTML Documents are called three ways:
From DTML -- A DTML Document can be called from another DTML
Method or Document::
dtml-var standard_html_header
dtml-var aDTMLDocument
dtml-var standard_html_footer
In this example, the Document 'aDTMLDocument' is being
called
from another DTML object by name. The calling method
passes the value 'this' as the client argument and the
current DTML names pace as the REQUEST argument. The above
is identical to this following usage in a DTML Python
expression::
dtml-var standard_html_header
dtml-var "aDTMLDocument(_.None, _)"
dtml-var standard_html_footer
From Python -- Products, External Methods, and PythonMethods
can call a DTML Document in the same way as calling a DTML
Document from a Python expression in DTML; as shown in the
previous example.
By the Publisher -- When the URL of a DTML Document is fetched
from Zope, the DTML Document is called by the publisher.
The REQUEST object is passes as the second argument to the
Document.
"""
So - I had a look at DTMLDocument.py and saw the following method :
def __call__ (self, client = None, REQUEST = {}, **kw):
...
SO - I try to create this method for my product :
def __call__ (self, client = None, REQUEST = {}, **kw):
print client
print REQUEST
and it prints :
None
{}
It seems that in fact the DTML document doesn't actually pass _.None and
_ to my object. WHY ??
How can I enforce DTML Docs/Meths to pass it anyway ???
Many thanks,
P.-J.

[Zope] ZODB question: get older object versions without undo
I have two questons concerning ZODB: 1. Since ZODB does not overwrite objects on change one can get the older versions when undoing the changes. My question now: how can I access older versions of objects without undoing transactions? (I had a short glance at the ZODB classes, but found nothing) 2.Is it possible ( or will be ) to define ZODB objects for which updates are done by overwriting and not appending to theobject database - That is an important issue for objects that are subject to frequent and simple changes. For example Webcounters or Advertising banners that count the clicks. Solutions to write these changes into external files (like FSCounter) are not more than emergency solutions for me. thanks phil
RE: [Zope] Access Control vs Publishing Protoco
This is because the thing which makes
the problem hard is that something like standard_html_header
wants to be
editable by Managers TTW, which means it also has to be visible TTW.
However, it's probably not something you want exposed to anonymous
users, especially as a TTW enitity in its own right. objectIds is my
other favourite example ;-)
OK, I'm still a newbie, and in particular I have yet to get my head round
zope security properly. But I'm going to attempt to comment on this anyway.
For me, the 'visibility' problem is a real bugbear. Apart from the
'security' issue of anon. users being able to list objectIds, it means I am
loathe to allow clients to manage their sites through the manage interface.
This is because they'll see it littered with methods which pop up a login
box whenever they click on them. It looks horrible and unprofessional.
Anyway, I agree with Dieter / Chris. Adding a 'URL Traversable'
('listable'?) permission to all objects and then tweaking methods that do
the traversing (objectIds, objectValues) would presumably fix this? Would
this be easy? I've never had a look at the security internals, but I'm
looking forward to having a go...
Chris W was talking about adding security on a protocol level as well as an
object level, but I can't really see why you would only want to be able to
edit a document through webDAV but *not* TTW. In my mind, you're either
authenticated to do a task, or you're not. It doesn't matter *how* you do
it. That's why 'listable' or something like it would be a better name for
the permission than 'URL Traversable', IMHO (although they both sound
*ugly*). Someone mentioned they found the ftp access permission useful -
I'd be interested to know how / why.

Instead, it will probably be something more flexible that doesn't require an all-appends strategy to maintain transactional integrity (or at least one that abstracts this behavior out). With a (as-yet-mythical) next-generation storage, there will be a more granular way to indicate that you'd like an object to overwrite a previous historical revision. ___ 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 )

Re: [Zope] Newbie question : ZopeTime permissions
Yes, it was a misunderstanding regarding basic user permissions and the Anonymous role on my part. I did not want to allow the Anonymous role *any* permissions, and the site I am working in is contained in a folder beneath the root Zope folder. The problem was that I had disabled the "Access contents information" privilege for the Anonymous user (whose permissions I forgot are inherited by all other users) at the root level, thus preventing Joe User from being able to access internals(?) like ZopeTime even if [it] had permissions at a sub-directory level. If I've got it wrong, I would be grateful if someone would correct me. Otherwise, I hope that helps other newbies who find themselves in a similar situation.

Pierre-Julien Grizel wrote:
It seems that in fact the DTML document doesn't actually pass _.None and
_ to my object. WHY ??
This is deep voodoo that I don't fully understand. To me, it appears
that what you get depends on how your __call__ was called...
The arguments vary dependign on whether:
-you were called from a bit of DTML
-traversed directly through a URL
-called from soem python you wrote
Here's the scoop:
1. DTML Methods' __call__ signature is (client=None, REQUEST={}, RESPONSE=None, **kw).
The client,
REQUEST, and keyword arguments are layered to form the namespace for the Method, with
the keywords
on top, then the client, then REQUEST.
2. If you call a DTML Method in a Python expression, its namespace will be empty
unless you
explicitly pass a client, REQUEST, and/or keyword arguments.
3. URL traversal automatically tries to look up parameter names in the REQUEST. Both
REQUEST and
RESPONSE are found in REQUEST, so they are passed to the Method.
4. When an object is named in the name attribute of a DTML tag, the DTML code checks
to see whether
the object is callable and has a true attribute called "isDocTemp". If so, it passes
the namespace
to the REQUEST parameter. Otherwise, if the object is callable it calls it with no
arguments.
Thus, to simulate dtml-var foo in Python code, including DTML expressions, you must
either use
"obj(_.None, _)" or "obj(REQUEST=_)".

[Zope] how to call sequence-item
Hello,
I'm using the photo-product, when one has created a photo-instance "image"
you can render this like so:
dtml-var "image(display='thumbnail')"
now I wanted to loop over all photos in a folder "Images" and did:
dtml-with Images
dtml-in "objectItems('Photo')"
dtml-call "REQUEST.set('bild',_['sequence-item'])"
dtml-var bildbr
/dtml-in
/dtml-with
that displays all photos in their original size, but
dtml-var "bild(display='thumbnail')"
gives:
Error Type: TypeError
Error Value: call of non-function (type string)
how can I call a sequence-item ?

Re: [Zope] Black Magic
Evan,
The information you just provided about the DTML Method "call
signature" and the like is very useful. Is this kind of reference
material written down somewhere in a guide/how-to/wiki/...?
I tried to figure out the call signature of a Python method by having
the called function use just "(*varargs, **kwargs)" as formal
parameters, but the inscrutable mapply() function seems to thwart that
effort as mapply() adjusts the function call according to what
parameters the called function (or callable object, ...) expects.
Very weird. Is there some document that covers the how and why of
mapply()?

I've compiled up the ZMySQLDA product and put the MySQLModule.so in the correct place (ie one directory up from the src directory). I've restarted the Zope server, checked that ZMySQLDA is not broken and created a connection: test@localhost root I've created a ZSQL method that is essnetially 'select * from my_table' (and there *is* data in this table). The DA reports: There was no data matching this Z MySQL Database Connection (connected) query. The same query produces a flood of data from the mysql monitor.

Re: [Zope] ZODB question: get older object versions without undo
Hello Philipp! 1. Since ZODB does not overwrite objects on change one can get the older versions when undoing the changes. My question now: how can I access older versions of objects without undoing transactions? (I had a short glance at the ZODB classes, but found nothing) The code for the History functionality is in History.py, which is located in the .../lib/python/OFS directory of a Zope 2.2.x installation. It is currently used by DTMLDocument .py and DTMLMethod.py (both also in OFS) and implements the history tab functionality for the management interface. As the actual implementation is plain simple (import History, add "History.Historical" to the class definitions and "+History.Historical.manage_options" to the manage_options), I patched my Image.py, which defines the classes for images and files, accordingly. The only thing that won't work right "out of the box" is the "Compare" option - you'd have to implement document-specific comparison code. I don't know if it is that easy to do the same patch with ZClasses, but it might be worth a try (I guess patching the necessary base classes should work). As you can script everything in the management interface, this patch makes all your file/image objects' old versions accessible, including date of change and id of the person who changed. I think it would also be possible to look at what History.py is doing and implement the functionality you need without the "overhead" of patching the object classes. I didn't check in detail, but all you need seems to be there (or should be found in some ZODB documentation). Regards Joachim.

Evan already answered, but the short story is:
your object needs to have an attribute (it may be a class
attribute and usually is) named "isDocTemp", and this attribute
must evaluate to true. Otherwise, your object is called with no
parameters.
The relevant code is:
if hasattr(v,'isDocTemp') and v.isDocTemp:
v=v(None, self)
else:
try: v=v()
except (AttributeError,TypeError): pass

RE: [Zope] Access Control vs Publishing Protoco
Seb Bacon writes:
For me, the 'visibility' problem is a real bugbear. Apart from the
'security' issue of anon. users being able to list objectIds, it means I am
loathe to allow clients to manage their sites through the manage interface.
This is because they'll see it littered with methods which pop up a login
box whenever they click on them. It looks horrible and unprofessional.
I just tried what would happen (as I did not believe it would be
as bad as you described it):
* I gave "Anonymous" the "View Management Screens" permission
for a folder.
* I was then able to access the manage URL for the folder
(without authentication), but the main frame displayed
an acquired "index_html" rather than the folders content
view.
* I tried to manage a containing DTML method, but a login
was requested: "No authentication header".
Apparently, DTML method management requires at least
an authenticated user.
Thus, I played with an authenticated user.
The behaviour was not too bad (though not completely satisfactory).
As you expected, the folder contents displayed all containing
objects, even objects I did not have "View" permissions.
When I clicked on such an object, I got an "manage_workspace" screen
with just the "ownership" tab. Not overwhelming but not too bad either.
When I had "View" permissions but no "change" permissions, I
did not get a "manage_workspace" screen, but the object was
viewed automatically. Not what I would have expected, but not too bad
either.
When I had a "change" permission, I got the expected "manage_workspace"
screen.
Anyway, I agree with Dieter / Chris. Adding a 'URL Traversable'
('listable'?) permission to all objects and then tweaking methods that do
the traversing (objectIds, objectValues) would presumably fix this? Would
this be easy? I've never had a look at the security internals, but I'm
looking forward to having a go...
I think, the implementation would be easy.
Management, however, would be more difficult, as there are no
good defaults for the "URL Traversable" permission.
It is not easy, to determine (e.g.) for a DTML method/document
whether it is only used as a component (such as
"standard_html_header") or is a full grown presentation method.

Re: [Zope] Newbie question : ZopeTime permissions
Aaron Straup Cope writes: I did not want to allow the Anonymous role *any* permissions, and the site I am working in is contained in a folder beneath the root Zope folder.

Sorry, I was wrong, at least partially! The fact, that "ZopeTime" returns an unprotected DateTime object, does of cause not mean that "ZopeTime" itself is unprotected. After your message, I reexamined your problem: * "ZopeTime" is defined in "OFS.Application.Application", i.e. the top level application object. * "ZopeTime" apparently is not protected by an explicit permission (neither mentioned in an "__ac_permissions__" nor is there a "ZopeTime__roles__" attribute nor is there a new SecurityManager assertion about "ZopeTime". As I understand Zope 2.2 security, this should mean "ZopeTime" is inaccessible from DTML. * However, magically, "ZopeTime" is protected by "Access Contents Information". I can not tell you why. Both is astonishable: * that it is accessible by DTML at all * why "Access Contents Information" is required. Apparently, the Zope security still has some hidden magic.

[Zope] Help with a DTML expression/comparison
Hey to everyone,
I'm shooting myself in the foot here with this
construct:
select name="begin_day" size="1"
dtml-in "_.range(1,32,1)"
option value="dtml-sequence-item;"
dtml-if expr="begin_day == _.getitem('sequence-
item')"
selected
/dtml-if
dtml-sequence-item;/option
/dtml-in
/select
Inserting with dtml-var any of begin_day or sequence-
item yields at some point the same result, logically.
I'm trying to make the form field default to a formerly
specified value.
BUT, the comparison between the two, won't work. Even
comparing two _.getitems doesn't work. So it's
expected that at no point does the selected property
appear in my html source.
Please help. I'm shooting myself in the foot here.
Thanks in advance,
Manuel

So I just create bit and pieces that get called to form a UI.
Aquisition works too. I have a property in a containing folder, that I
called as the bgcolor of the table and it worked fine.

Re: [Zope] Where is the difference between URL0 and BASE3
Loibl Johann writes:
Could someone tell me where is the difference between
URL0 and BASE3 or
URL1 and BASE2 ...
URLn removes "n" URL path components from the right,
BASEn consists of the first "n+1" or "n+2" URL components.
Thus, if you URL is "host/u1/u2//un",
then URL0 is URL, URL1 is the last component "un" removed,
ULR2 is the last two components "u{n-1}/un" removed etc.
Usually (unless you access Zope via CGI), BASE0=BASE1=host.
BASE2 is "host/u1", BASE3 is "host/u1/u2" etc.
If your URL has 3 components, then URL0 and BASE3 are identical,
otherwise, they are not.

Re: [Zope] fmt=structured-text seems wrongish
Dennis Nichols writes: dtml-var "myDoc.description" fmt=structured-text And shouldn't the fmt specification tell how myDoc.description is to be presented instead of how it is stored? I agree with you that "fmt" should specify how the value should be formatted and not how it is stored. For example, let's say I can choose to store description as plain text, as structured text, or as html. Regardless of how it is stored, I might want to ask for it as: fmt=raw in case I want to edit it fmt=html in case I want to send it to a browser I fear, the "fmt" machinery will not know, how the value is marked up (plain/stx/html). This knowledge would be necessary for a format change. Currently, I would say, this is not a task for the "fmt" argument but for the application.

[Zope] Second question ?=)
This is my second question: Id like to run a dtml-in sqlquerymethod with specific parameters to its namespace This is the deal I want to construct a dropdown list, with all values retrieved from a SQL stored procedure, so if I open the form with no variables, all of them appear, but if i submit the form to itself, the variable gets passed on to parameters, and the SQL query receives it because it's on its parameter list, and filters the query. I don't want to alter the SQL query methods to fetch all data, but i'd like to override the values of its namespace so I can specify NULL and get all data, and in calling method compare each data in the dtml in loop to insert a selected property in the dropdown object that matches the existing variable.

[Zope-dev] Help, please!!! __call__ problems with DTML templates
Today is not a good day:-( I've just spent 2 days trying to force
__call__ to render my product properly, got every error possible at least
seven times, and wasted last night working out what was wrong with Refresh
(I was calling refresh on the wrong product. Duh!).
Please, please, please, can someone point me in the right direction.
I have a class called Element which has three components:
1. purpose: a string describing the element's role (rendered as structured
text)
2. template: a string that is rendered to display the element (DTML)
3. Element inherits from Folder so it can contain sub-elements which can be
included in the template
For example, suppose A is an element that contains a sub-element B (i.e. B
is A.B)
Ahas template 'Element A contains dtml-var B'
and purpose 'Contain B'
Bhas template 'element B, which contains nix'
and purpose 'Element with no subelement'
Now for the tricky bit: "dtml-var A" needs to be rendered one of three
possible ways depending on a variable in the REQUEST. So __call__ needs to
return one of
- case a: the purpose property (as structured text) wrapped in []
- case b: render the template, with sub-elements properly rendered
- case c: render the template, with sub-elements wrapped in [] showing
their purpose
Then 'dtml-var A' must be rendered in the three cases as:
- case a: '[Contain B]'
- case b: 'Element A contains element B, which contains nix'
- case c: 'Element A contains [Element with no subelement]'
To do this, I need to write my own __call__ method since __call__ is what
detemines how objects gets rendered in DTML (is this correct?)
def __call__(self, client=None, REQUEST={}, RESPONSE=None, **kw):
With this, I discovered that 'dtml-var A' gives client=None and REQUEST={}
while
'dtml-var "A(_,REQUEST)"' gets client=_ and REQUEST=REQUEST.
But I cannot for the life of me, work out how to do what I need. In
particular:
1.) How do you magically get the DTML context from 'dtml-var A' without
having to resort to 'dtml-var "A(_,REQUEST)"' in the templates?
In the __call__ methods of different classes, I've seen some code like:
'if REQUEST is None and not kw: REQUEST=self.REQUEST' (from
Catalog.py)
and other code like
'if hasattr(self, 'aq_explicit'): bself=self.aq_explicit else:
bself=self' and
'security=getSecurityManager() security.addContext(self)'
(from DTMLDocument.py)
I can't see any consistency in what these classes are doing, so I don't know
what I need to do.
2.) How to convert an arbitrary text string into rendered DTML inside a
python product method?
How do you get the object's properties, REQUEST and acquisition context all
in the namespace?
I've been trying code like:
template = 'span class="purpose"dtml-var purpose
fmt="structured_text"/span'
dtml = HTML(template, globals())
rendered = dtml(self, REQUEST)
but this doesn't work. All the example classes I've seen (such as
ZWikiPage.py in ZWiki) use DTMLDocument as their base class so can call
DTMLDocument's __call__ on themselves as in
text = apply(DTMLDocument.__call__,(self, client, REQUEST, RESPONSE),
kw)(ZWikiPage.py, line 135)
This doesn't help me because I don't have DTMLDocument as a base class.
Looking through the source for DTMLMethod etc is not very clear because lots
of "apply(__call__,(...),kw)" calls are all mixed up with acquisition code.
3.) Do I need to write a custom tag (dtml-element A) to get this
behaviour?
So, if anyone out in Zope land can help me, I'll be eternally grateful. I've
exhausted my patience looking through the NIP mailing list archives, the
How-Tos and the Zope site and need to have something to demonstrate on
Thursday.
Thanks in advace,
Stephen
P.S. ChrisW, searching NIP for "__call__" returns every message with 'call'
in it, which is not quite the same thing!

I want the information from that box to be input into a database table upon clicking the Submit button. I cannot figure out how to get that information from point 'A' to point 'B'. Assuming your form has a field named the same as all of columns you want to insert (i.e. Foo, bar, whatever)... Then you can have it post to another method that has a line like this in it: dtml-call name="sqlInsertValues" And then have a SQLMethod called 'sqlInsertValues' that has a body like this: INSERT INTO mytable ( column1, column2, column3 ) VALUES ( dtml-sqlvar name="column1" type=string, dtml-sqlvar name="column2" type=int, dtml-sqlvar name="column3" type=string ) Remember to put these in the arguments list, or they won't be caught from the REQUEST namespace.

Re: [Zope-dev] Help, please!!! __call__ problems with DTML templates
Stephen Simmons wrote: 1.) How do you magically get the DTML context from 'dtml-var A' without having to resort to 'dtml-var "A(_,REQUEST)"' in the templates? Give your class a class attribute of isDocTemp=1. This tells the DTML method calling machinery that you want to receive the namespace as REQUEST as the third argument to your __call__ method. There was a thread on this in zope-dev on and around 26 September, subject "more __call__ ..." In the __call__ methods of different classes, I've seen some code like: 'if REQUEST is None and not kw: REQUEST=self.REQUEST' (from Catalog.py) Your method will usually get called with its third argument as the namespace, or REQUEST. However, sometimes, it may just be called with a "self" argument. The code in Catalog.py is falling back on getting the REQUEST out of the self argument, if it is not explicitly passed a namespace to work with. I can't see any consistency in what these classes are doing, so I don't know what I need to do. Most developers would like more consistency here :-) I'm hoping that all this will be much much clearer for Zope 2.3. That doesn't help much for now though. 2.) How to convert an arbitrary text string into rendered DTML inside a python product method? How do you get the object's properties, REQUEST and acquisition context all in the namespace? I've been trying code like: template = 'span class="purpose"dtml-var purpose fmt="structured_text"/span' dtml = HTML(template, globals()) If all you want to do is render some Structured Text, you can import and use the StructuredText module directly. P.S. ChrisW, searching NIP for "__call__" returns every message with 'call' in it, which is not quite the same thing! For cases like that, I have downloaded the plaintext mail archives as available from http://www.zope.org/Resources/MailingLists I then use unix grep on them to search for just what I need. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

I've been trying code like:
template = 'span class="purpose"dtml-var purpose
fmt="structured_text"/span'
dtml = HTML(template, globals())
rendered = dtml(self, REQUEST)
Here's an except from my Python interactive interpreter:
import DocumentTemplate
my_dt=DocumentTemplate.HTML("""dtml-var "1+a)
my_dt(None, {'a':4})
'5'
The object my_dt is callable, and takes the arguments (client,
namespace). You can put a REQUEST in place of the simple dictionary I
used above.
If you're trying this, make sure you have the PYTHONPATH environment
variable set to /your/zope/directory/lib/python

1.) How do you magically get the DTML context from 'dtml-var A' without
having to resort to 'dtml-var "A(_,REQUEST)"' in the templates?
A.isDocTemp = 1 # or make it a shared class attribute
2.) How to convert an arbitrary text string into rendered DTML inside a
python product method?
Here's what I use:
from Globals import HTML
from AccessControl import getSecurityManager
class DTML(HTML):
"""DTML objects are DocumentTemplate.HTML objects that allow
dynamic, temporary creation of restricted DTML."""
def __call__(self, client=None, REQUEST={}, RESPONSE=None, **kw):
"""Render the DTML given a client object, REQUEST mapping,
Response, and key word arguments."""
security=getSecurityManager()
security.addContext(self)
try:
return apply(HTML.__call__, (self, client, REQUEST), kw)
finally: security.removeContext(self)
def validate(self, inst, parent, name, value, md):
return getSecurityManager().validate(inst, parent, name, value)
