subject:"RE\\\: \\\[Zope\\\] help"



Thanks AJ. I assumed an OODBMS would be the right choice because of the object 
nature of my 'tools'. Of course, it was an assumption. Instead of 
Pyramid+RDBMS, can I use PHP+mySQL (my current hosting provider supports 
this).If ZODB isn't for my project, then would a GraphDB help? I have no idea 
on where to start with Graph DB - I've read the wikis and it's made me more 
confused.

 Where would you take advantages from using Zope as framework?
 This sounds like a task for Pyramid + RDBMS or a graph DB.

 This hardly depends from your data structure, but with Zope you have the 
 option to use ZODB and SQL DBs like MySQL in parallel. Typical relational 
 data should go into a SQLDB while complex / oo Data structures should go into 
 ZODB.

 We developed several complex to very complex web based applications - incl. 
 expert systems - on Zope ZODB plus MySQL. I can't believe that someone would 
 be able to solve such issues with PHP/SQL within the same time / ressources.

  Which is the best place to start learning for a
 newbie?
 You should start by trying the short zope practice / excercise as described 
 in the Zope book.

 The Zope Book should be the best source for getting into Zope step by step 
 from nothing. ß)

  Can anyone recommend a good shared hosting provider that
 supports Zope fully but is not expensive?
 Looking for zope hosting or similiar in google should advice you. Our 
 company - as one of many - offers Zope hosting to.

 Is there a module or app that
 is open source that I can use to output a graphical flowchart based on
 the results, or will I be better served programming it from scratch
 with Python?
 There are different modules as i.e. Python Imaging (PIL) and higher level 
 modules.

 I would appreciate any help in getting started. Thank you
 in advance. I have tried most online forums but have not good any
 productive answers. Most of the answers I got were pro-PHP+mySQL.

 Yes, because the peoples did not know anything other solution usually...

Data modelling is a bit of an art and probably you could tackle your 
problem with any approach. I think the important is for you to figure 
out which model suits more your personality. No kidding.


I would personally start with the RDBMS approach considering only the 
information you provide. Also, you can easily use zope in combination 
with a RDBMS. When you read the book, beware that zope has been changing 
from a through the web approach, to a typical file system based 
approach, which is a loss, but it seems to be what suits the needs of 
the zope developers.


The approach I use is:

zpt page - (one) Python Script - (some) ZSQL Methods - MySQL

The zpt defines the layout of the pages, the ZSQL Methods retrieve the 
data needed and the Python script massages the data to make it suitable 
for the ZPT page. Or the other way around, from user input in a form to 
storage in the database.


The advantage of the relational approach is that it is a very well 
understood model and although different people will still come to 
different models there are sufficient objective guidelines out there 
(e.g., the normalization rules, and then criteria for when to 
denormalise) to help you along. Furthermore, there are lots of people in 
db-related forums that can help you.


Also, RDBMS provides you with a standard query language, SQL, which 
plenty of systems and tools can use. In general, RDBMS gives you the 
safest approach to keep your data and not loose it when you need to 
migrate either the front-end or the back-end. This language is very 
powerful and can avoid you a lot of low level programming.


However, plenty of people can not deal well with SQL because it follows 
a paradigm so different from the classic imperative programming. With 
SQL, you specify the what, with the other languages you specify the 
how. The advantage of the what is that you can do a lot of data 
processing in a few lines of code. The problem with the what is that 
because you don't know the how of it, you feel you don't have control 
and you are led to say the language is obscure or unreadable.


However, even if you are not comfortable with the what (you have to 
try to know), you can still rely on an library like SQLAlchemy to keep 
you a bit in the comfort zone of the how. So instead of learning SQL, 
you need to learn the API of a specific library. Your choice. I 
recommend the first by far.


The real main issue with Relational is that it is a highly structured 
data model. It allows you to keep high quality data but if you don't get 
it right soon enough in the development cycle, some later changes can 
have a huge impact in the application, requiring rewrites. Furthermore, 
it works the best when you have many objects with the same properties. 
If you have many entities all different from each other (the tools in 
your case, maybe), then maybe a OODBMS might be better. But here, there 
is no standard language, or standard whatever. Perosnally, I would avoid 
as much as possible to put data in something like ZODB (I use it merely 
to store and manage the application).


The problem with your specific case is that it does not seem to be a 
typical case of books and authors, which might be a risk for someone 
without experience. The issue Tool A might have only three fixed rpms - 
100, 200 and 500, but Tool B might have rpms from 20 to 2000, is indeed 
tricky. I suspect in general the needs of your system will be too 
specific to be able to rely only on SQL queries. You would need to put a 
lot of intelligence in the data (really highly structured) and it might 
become unmanageable or not scalable.


I guess you will need to put a lot of intelligence in the Python Script. 
So, the ZSQL retrieves the relevant tool data and then makes the tool 
choice. The knowledge of the meaning of the attributes is maintained in 
programming.


I should say I am not totally sure the Python Script is the best 
approach here, in terms of management facilities. But Python is surely a 
very good language due to its readability. However, you might need to 
use External methods or a more typical file-system based Python approach.


Or maybe you actually need to create a Domain Specific Language to 
encode the intelligence needed for your tool selection process. If your 
python code becomes repetitive, with patterns showing up, then a DSL 
might be a good approach, but this might be too much engineering for you 
at this stage. It looks like you are in a typical CIM scenario and I 
remember handling a similar problem 20 years ago. I vaguely remember at 
that time to use custom graph structures in C and the the intelligence 
was coded in Lisp/Scheme. So, there is a big range of solutions to try 
out :)


If you have time, then the simple approach

zpt page - (one) Python

Re: [Zope] Help in deciding approach to Web App



Thanks Fernando! I really appreciate the time and effort you have put in 
answering my query. My personality sides with Python but my hosting provider 
does not support Django or Zope.
As you mentioned, if I have to use mySQL, isn't it better for me to go with 
PHP+mySQL - easier to learn and deploy? Can I just start out with a framework 
like Symphony instead?
In the future I'll have to use either Python or C/C++ for my business logic and 
math. But the focus now is to get a prototype out, and if I'm doomed to change 
everything later I might as well start with the easiest and most obvious. Is 
this a viable starting point compared to what you have suggested? Or am I 
missing something?

2011-12-04 Thread John Schinnerer


Aloha,

Very briefly, from what you describe, it looks like you are dealing with 
large numbers of complex objects (your 'tools') that interact with each 
other - and with some other elements that are going through this 
workflow process? And a context for the process? ...not sure of that part...


In any case, this looks (to me anyhow) like a very object-oriented 
system you are modeling so an object oriented approach and language 
would seem most suitable. Python is one reasonable language option; zope 
for the web publishing aspect of the project would fit well with that. I 
haven't worked with other OO languages enough to usefully compare.


It also sounds to me like the web publishing is the lesser part of 
this...? That is, the workflow of interacting tools is the real 'app' 
here, a process which does not all get shown somehow on a web page...or 
does it? Or just the outcomes?


LAMP platform is so common and cheap that it's all a lot of people know 
about. It can be used well, and, it is all too easy to make horrible 
hacks and Frankestein monster apps in PHP/MySQL.


Meaning, a highly structured (yet powerful) OO programming language will 
support you in avoiding that.


Also, for development (or just to explore if python+zope might meet your 
needs) you don't need any hosting, you can install python+zope on your 
development system and try it out.


best wishes...
John S.

 logic/rules involved.
 
 If possible, I would also like the app to output a graphical 
 flowchart at the end showing the workflow with all tools grouped in 
 an easy to understand layout.
 
 
 *My questions:*
 
 1. Will the app be better served with a relational DB like mySQL or 
 an Object database? After a lot of research I've guessed that my 
 particular case might be better served with Python and Zope/ZODB.
 But I might be wrong? Maybe PHP+mySQL or Django is a better fit? 2.
 Can anyone provide general advice on how to go about beginning such
 a project in ZOPE. Which is the best place to start learning for a 
 newbie? 3. Can anyone recommend a good shared hosting provider that 
 supports Zope fully but is not expensive? 4. Is there a module or
 app that is open source that I can use to output a graphical
 flowchart based on the results, or will I be better served
 programming it from scratch with Python?
 
 I would appreciate any help in getting started. Thank you in
 advance. I have tried most online forums but have not good any
 productive answers. Most of the answers I got were pro-PHP+mySQL.

Unlike a DTMLDocument, a DTMLMethod does not change the context

you may even loose all context.

After you skimmed the book, come back if questions remain.

This description is pretty poor. In general: the mapping of domains -
Zope host/port is known as virtual hosting and usually configured
through rewrite rules or something similar within your front-end proxy
(Apache, Squid  friends) - or old fashioned through settings
within the instance of the virtual host monster somewhere in the root

Re: [Zope] Help writing test where bobobase_modification_time changes

2008-04-11 Thread Peter Bengtsson

Thanks for the tips Chris and Dieter, I actually solved it in a very simple way:


from OFS.Image import File
from time import time
class MockFile(File):
 This file works the same as a normal File expect that
in manage_edit() the internal modification time is set immediately.
Normally Zope objects get their internal modification set when
the transaction manager commits.


def manage_edit(self, title, content_type, precondition='',
filedata=None, REQUEST=None):
# here's the mock hack, we set the _p_mtime NOW instead of letting
# the transaction manager do it at the end.
self._p_mtime = time()
return File.manage_edit(self, title, content_type,
precondition=precondition,
filedata=filedata, REQUEST=REQUEST)

This worked beautifully in the integration test. I'm happy.

The reason it fails on the last line is that the time difference
between the first time and the second time is nil. Adding a
time.sleep(1) won't change anything because the
bobobase_modification_time() doesn't change.

How can I solve this?

Not easy.

bobobase_modification_time() is in fact a DateTime representation
of _p_serial. And _p_serial is the transaction id (also a timestamp)
that has committed the object state belonging to this object incarnation.

Unfortunately, you must not commit a transaction in a test suite
(as this may cause interference with other tests).

There is a small chance that a savepoint changed _p_serial --
but the chance is only small...

You might be able to write _p_serial yourself and thereby
trick bobobase_modification_time().

Re: [Zope] help with customizing error messages, Zope 2.9

2007-09-21 Thread Dieter Maurer

Dennis Allison wrote at 2007-9-20 09:37 -0700:
 ...
standard_error_message should be acquired.  It should be possible for
there to be multiple copies with the particular one to be used selected by
acquisition.  This does not appear to be the case for some errors in my
configuration, but I am not sure why.  

You are right -- and I can explain why.

There appears to be nothing in the Zope 2.9 zope.conf file that has to do
with catching error messages.  Is there some configuration that is 
missing to enable full custom error messages.

Looking at the code:

ZPublisher/HTTPResponse.py seems to have a complete set of error
responses hard-wired with outputs that mimic those of the default
standard_error_message.

OFS/SimpleItem.py includes a method called raise_standardErrorMessage
which first acquires and then publishes the standard_error_message.

Zope2/App/startup.py has a method, zpublisher_exception_hook which 
uses raise_standardErrorMessage and is referenced in ZPublisher/Publish.py
where it is used to set error_hook, but error_hook does not appear to be 
used.

It would be helpful to me if someone who understands how this particular 
code works could provide some hints as to what's needed to fully customize 
the error message responses.

We start with ZPublisher. It is this component that
catches the exception and activate error handling.

ZPublisher was designed as a general publication component -- to
be used not only for Zope. Therefore, it has
neither error handling nor transaction handling nor a few other
things hard coded.
Instead, it gets a module name and determines the relevant
pieces by a call to ZPublisher.Publish.get_module_info(module_name).

When ZPublisher is used for Zope, then module_name is
Zope2. Zope2 defines Zope2.zpublisher_exception_hook
as its exception hook (which does the error handling).
The true zpublisher_exception_hook is defined
(as you found out) in Zope2.App.startup and copied
to Zope2 by the _startup call.


When ZPublisher catches an exception, it calls the error hook
with parents[0] (the last or second to last object traversed to), the
request and the error information.

zpublisher_exception_hook then looks in the
acquisition context of parents[0]
for 'raise_standardErrorMessage' and 'standard_error_message'.
If either of them is not found, the exception is
raised -- and handled by the response object in a standard (minimal) way.

Otherwise, 'raise_standardErrorMessage(standard_error_message, ...)'
is called.


The problem which sometimes causes surprises with respect
to the used 'standard_error_message' lies in parents[0]:

  When the exception happens during traversal, then
  parents[0] is not the object you may expect -- but
  lies above the expected object.

  The problem is especially bad when the exception
  is raised by request.processInputs. In this case,
  the traversal did not even start and parents[0]
  is the root object. Consequently, for these exceptions,
  you will always get the standard_error_message from your
  root folder -- even when the request was targeted to some
  object deep inside your site.

  processInputs may raise exceptions when you use e.g.
  ZPublisher type conversions, e.g. :int or :float
  and the provided value cannot be converted.
  If you do not like this, you should not use ZPublisher
  type conversions.

accepts float and that necessitates some surprises with
time discontinuities (such as daytime saving switches).

I don't know what your problem is, but here are some code snippets I used to 
get around a timezone problem I was having:


# def custom timezone class

   def utcoffset(self, dt):
   STDOFFSET = datetime.timedelta(seconds = -_time.timezone)
   ZERO = datetime.timedelta(0)
   if _time.daylight:
   DSTOFFSET = datetime.timedelta(seconds 
= -_time.altzone)

   else:
   DSTOFFSET = STDOFFSET
   if self._isdst(dt):
   return DSTOFFSET
   else:
   return STDOFFSET

   def dst(self, dt):
   STDOFFSET = datetime.timedelta(seconds = -_time.timezone)
   ZERO = datetime.timedelta(0)
   if _time.daylight:
   DSTOFFSET = datetime.timedelta(seconds 
= -_time.altzone)

   else:
   DSTOFFSET = STDOFFSET
   if self._isdst(dt):
   DSTDIFF = DSTOFFSET - STDOFFSET
   return DSTDIFF
   else:
   return ZERO

   def tzname(self, dt):
   return _time.tzname[self._isdst(dt)]

   def _isdst(self, dt):
   tt = (dt.year, dt.month, dt.day,
   dt.hour, dt.minute, dt.second,
   dt.weekday(), 0, -1)
   stamp = _time.mktime(tt)
   tt = _time.localtime(stamp)
   return tt.tm_isdst  0


# usage code...
   Local = LocalTimezone()
   chkDate = datetime.datetime.now(Local)
   now = datetime.datetime.now(Local)

   # see if we have to apply a local timezone offset
   if tzo:
   # get the number of hours less than UTC (GMT)
   localTZO = int(chkDate.strftime('%z')[0:-2])

   # make sure we have the target tzo as an integer
   targetTZO = int(tzo)

   diffTZO = 0
   if targetTZO  localTZO:
   diffTZO = -(-targetTZO + localTZO)

   elif targetTZO  localTZO:
   diffTZO = (-localTZO + targetTZO)

   if diffTZO:
   # we have to adjust our dates to account for the 
time zone difference
   chkDate = chkDate + 
datetime.timedelta(hours=diffTZO)

   now = now + datetime.timedelta(hours=diffTZO)

   # create a time delta object (a date/time object that is a duration) 
for 6 months

   maxDate = datetime.timedelta(weeks=24)

   # check for events within a 6 month window
   while chkDate  now + maxDate:


This code was just ripped from an application, but may provide you with some 
ideas for a work-around.

application/x-gzip-compressed or similar (it gets
application/octet-stream).

As far as I understood from this case, such mime type info is passed
by user's system (where Windows usually is not aware of tar.gz, tgz
etc format) rather than being set by zope server.


AFAIK..all Zope types derived from OFS.File or OFS.Image are using
OFS.contenttypes.guess_content_types()...if the 'content-type' header
isn't available. Otherwise Zope will use it.

Re: [Zope] help, installing ZJetDA-0.1.1..

2006-12-05 Thread Maciej Wisniowski


 Hi, I have copied the folder of the ZJetDA-0.1.1 product 
Have you seen how old ZJetDA is? I'm not surprised
it doesn't work with Zope2.10.
If you want to use this you'll possibly have to modify
it's code.

Better look for different database adapter. I think
that mxODBC might be best solution for you.

Re: [Zope] Help! Can't Log Into ZMI!!

2006-11-27 Thread Nancy Donnelly

 When you have access to the ssh on your server i think you can set an
 'master password' 

I couldn't even pull up the ZMI password dialog box. But I figured it out. I 
changed IP addresses and needed to update that in the zope.conf because ZEO 
listens on port . 

I wonder why I can't just use the localhost address: 127.0.0.1 ? Doesn't seem 
to work.

Hi;
I added a LDAPUserFolder instance to my Plone. It didn't connect for
whatever reason. I rebooted the server. Now I can't log in! It just hangs.
Actually, I rebooted a day later and did lots of work in between, so it's
not like I could carefully edit the Data.fs. What do I do?

Hi!

I've an old machine with zope 2.6 with an application based on 
ZClass. Now, updating 4000 record takes ages (more than an hour...), 
basically it is a propertysheet update + recatalog of every object of 
4000.

Can I have significative performance upgrade changing something in 
the code base? Some ZCatalog slow bug in 2.6 I could patch you know 
of? :)

You could try different transaction subcommit threshold settings 
(Catalog - Advanced tab) to see if different settings have any 
beneficial impact.

Subtransactions are *Disabled :)

Re: [Zope] Help! Zope Crashed! Production Server!

2006-10-05 Thread Marco Bizzarri


Since you're running it with runzope (i.e. in foregreound mode):

1) Can you confirm Zope provided the message Zope Ready to handle requests

2) What is the top command showing? Is python/zope process using CPU,
or is it simple unresponsive?

3) Can you check if there are different processes when you start and
when you do your first request? With some C extensions of python, you
can end with hanging python processes (at least on Linux; don't know
on FreeBSD).

4) Is the zope process able to write to Z2.log, event.log and (if
used) trace.log?

Hope this can help.

Marco

When I ps wax I see Zope is working. However, when I surf to sites, or even the IP address, it just hangs! 

Stop Zope and check whether you still have any Zope processes.
If so then kill'em and then try to run Zope again. I had similiar
problems with hanged Zope processes. Maybe that's your's
problem too.

You may use netstat to check whether your Zope is listening.

So, I've unpacked the files to Products dir. I'm supposed to create a
ZFSPath object somewhere. How do I excactly do that?

Maybe, you start reading the Zope Book (2.7 edition, online)
and learn how objects are created in general.

Okay, if you can get parse_file to return a list of dictionaries like:
[
  {
   'folder':'whatever',
   'label':'whatever',
  }
]
...then you can do:

span tal:define=opts 
python:here.lib.parse_file(file=here.news,sepr=',',clone=1)

  li repeat=opt opts
a tal:content=python:opt/label
   tal:attributes=href string:news_items/${opt/folder}/

You can find out about packages that are installed with dpkg -l zope*

This should show at least zope-2.7. If that shows up you can find the

You drastically restrict access to the LocalFS content (e.g. by
granting the Access contents information and View permissions
only for Manager) and provide access to it via a Python Script
with proxy role Manager.
This script can check any conditions you would like to be fulfilled
before it grants access.

Bruno,

Maybe you can better explain your question. Im not at all sure the 
following will help:


Seems like you can check a users credit at login, store the credit score 
in SESSION and use that for branching logic.  You could also update the 
creditScore as it changes.


Then you can develope your pages with stuff like this:  (syntax not checked)

in TAL

a hRef=somewhere tal:condition=python:  
request.SESSION['hasCredit'];This link only shows up if session's 
'hasCredit' is true./a


In DTML

dtml-if SESSION['hasCredit']
a hRef=somewhere ...
dtml-else
 hRef=somewhereelse

In Python: (and TAL macros)

  if context.REQUEST.SESSION['hasCredit']:
return container.Images.macros['allImages']  
  else
return container.Images.macros['someImages']

The merging of two zsql result sets is easy - here's one way:

for r in resultset1:
 newResults.append( r )

for r in resultset2:

return newResults.

The pages in the Document Root work fine. That is, the pages at
http://yourserver, which correspond to /var/www/html and
https://yourserver, which correspond to /var/www/html-ssl.

I have a config file called default, which is exactly like the ssl

Yes. Well, https://yourserver/plone.

  Order deny,allow
#Deny from all
#Allow from .your_domain.com
Allow from all
/Proxy

I've now got a further question, in case anyone feels like indulging me.

1) I can still access my plone site unauthenticated via
http://machine_address:9673/test_plone.

What is the best way to switch that off so it can only be accessed via the 
https interface?


Thanks. Faheem.

do the SSL encryption and decryption, then you need to set up mod_ssl, 
sort out the certificates, etc. I have this working on a few of my

Yes, at least part of the problem is that I did not have SSL set up

now, so I'll try the Plone thing again.

Ok. I've now configured SSL correctly on my test machine, but am still 
getting errors. I suspect this is an apache misconfiguration, which is 
puzzling, since I have acess to a machine doing very similar things, also 
running Debian sarge, which is working.


I'll list misc bits of info below, in the hope that this will help to 
narrow the problem. I'll also list the ssl config portion of my apache 
file at the bottom of this message for good measure.


1) Firstly, SSL is now working, certificates are offered and accepted, 
yada yada.


2) I can acess the page at

http://127.0.0.1:9673/VirtualHostBase/https/%{HTTP_HOST}:443/test_plone/VirtualHostRoot/_vh_test_\plone$1 
[L,P]


fine, where I have to replace 127.0.0.1 with the IP address of the machine 
in question. This means the Virtual Host Monster is working correctly, 
right?


3) The rewriting is actually happening, because the rewriting log shows

**

This all looks pretty normal.

4) The error log is fairly unhelpful. Setting LogLevel to debug does
not seem to give any helpful information.

The main error is

From: Faheem Mitha [EMAIL PROTECTED]
...
I running Apache 2.0 and Zope 2.7 on Debian Sarge. I've configured a zope
(Plone) instance located /var/lib/zope2.7/instance/dulci.

This can be accessed via
http://machine_address:9673/dulci. 9673 is the
^^
http

point on which Zope runs on Debian.

I'm trying to configure Apache so that all requests of the form

http://machine_address/plone are sent to

https://machine_address:9673/dulci
^^
https

http != https
Zope is unlikely to understand the rewritten URL with that https I would
say. I don't understand why you try to access Zope with SSL/https, plain
Zope does not understand that protocol.

If you try to use apache to do SSL for Zope, you will need it the other
way around.

And to force connections to go through SSL, you will need a rewriterule
to redirect (either for all URLs or for /manage URLs) or some fancier
Plone setup (which I never figured out).

and that the urls returned by Plone are consistent.

I added the following lines to my Apache config, representing my best
guess as to how this should work.

I don't know about the problems that Chris found with your RewriteRule,
but I stopped worrying, since I can always go to the witch and get a
usefull RewriteRule for most setups (if I might say so myself :-)
http://betabug.ch/zope/witch

The rewriting seems to work, since when
I go to

http://machine_address/plone

the log says

[Wed Nov 09 03:30:26 2005] [error] [client ...] client denied by
server configuration:
proxy:http://127.0.0.1:9673/VirtualHostBase/https/machine_address:443/dulci/VirtualHostRoot/_vh_plone

However, something must be broken.

...

RewriteRule ^/plone(/.*)?$
http://127.0.0.1:9673/VirtualHostBase/https/%{HTTP_HOST}:443/dulci/VirtualHostRoot/_vh_plone$1
[L,P]

As for the question mark, I guess you are trying to get in one rule what
most people (and the witch) do in two rules: Cover the case where
/plone ends the URL, as well the case where something comes behind
/plone. Regular expressions are tricky with that stuff, so it's better
to use 2 rules and be covered.

Googling for [zope apache rewriterule], the ZopeWiki page
(http://zopewiki.org/ZopeAndApache) comes on the first result page,
while the witch is currently on the second page. The help page from the
VHM is also very informative.

Sascha

This does not make any difference. Does this line, and the rest of the

Any idea what I might be looking for in the configuration? I'm mostly

Do I correctly understand that this rule will encrypt traffic sent to the

not) it keeps prompting the same.

If  I choose cancel your product show me the current message:

I have selected a Zope mailhost object



Please explain exactly what you did, including how you create the 
MailHost, the Mail Template and the Python Script, in detail...


I just tried to reproduce this on a fresh Zope 2.8.1 instance and 
couldn't...


Using the first example, the mail rendered and sent just fine.

I'm still far from convinced the thing you think is a MailHost object 
is actually a MailHost object, did you perhaps delete or rename your 
MailHost object?


Chris

I make it work , the fist time I try to use it I had copied my Mailhost 
object from another folder and it wasn't working. I delete it and create 
another one with a different name. When I go to the MailTemplate object 
to chooses my new MailHost it was already selected but still not 
working. The problem was solved when I push the save button any way and 
it works ...


Trying to execute the attachment example , you forgot to put ' ' on the 
second mail address  line: mto=('[EMAIL PROTECTED]',[EMAIL PROTECTED]),

And to send the attachment I get another error:
strongError Type: Unauthorized/strongbr/
 strongError Value: You are not allowed to access 'add_file' in this 
context/strongbr/


and the traceback:

I had change all my security options in the folder that I'm using the example

Am I doing something wrong?

PS: The test mail I received on the first simple example,  the part  a

tal:content=url/ doesn't render right , it actually show in the body 
of my message mail  like --  your interest in: a

Simple Example
 This example sends a simple templated mail to a specific

 Add the following to a Mail Template called my_mt:

 Dear tal:x replace=options/mto/,

d'oh, that's a typo ;-)

tal:x replace=options/message/

I'll go and correct that in svn now :-)

*yuck* tal to render plain text. Now thats ugly ;)


Suggest something better...

I find it convenient, especially for generating html mail, which 
customer have a habit of liking ;-)


On the development front, the fewer languages anyone needs to know to do 
development, the better. TAL/TALES works just as well here...

The opposite is true.. by keeping this on the list, not only can other

Hmmm, what have you selected in the MailHost drop-down on the Mail 
Template's edit page?


Whatever you have selected is resolving to a string instead of a 
MailHost object :-S
