Why dont you write this as plain python code?
Python Scripts are made for that.

This is even somewhat correct. If people had the discipline to not abuse
the templating to do complicated logic. 
The major drawbacks of DTML are: 

- one namespace (with transparent layers)
- confusing naming of tags, like  which
  really is  or something
- and the extra tags for flow control, but probably
  the dtml fans can live with it.
- peoples practice to use  even inside
  html-tags attributes, where &dtml-foo; should be used.

Unfortunately Plone is still a bad example for ZPT. It is getting
better but still it has a lot of code and definition in the templates.
Maybe AT would be a way out.

However, this is not a beginner tool.

Maybe you rather try this one:

http://mjablonski.zope.de/MailBoxer

which works with an existing mail server and is
more easy to use and debug.

If you have a simple product like this:

EmailTools/__init__.py
--- contents -
from AccessControl import allow_module, allow_class, allow_type
from AccessControl import ModuleSecurityInfo, ClassSecurityInfo

from email.MIMEText import MIMEText
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.Header import Header
from MailCrypt import signmail
from email.Encoders import encode_base64

allow_class(BlockFormatter)
allow_class(MIMEBase)
allow_class(MIMEText)
allow_class(MIMEMultipart)
allow_class(Header)
allow_class(signmail)
allow_class(encode_base64)
---

You can send mails with attachment like this:

from Products.EmailTools import
MIMEText,MIMEBase,MIMEMultipart,Header,encode_base64

msg=MIMEMultipart()
inner=MIMEText(mailtext,_charset='iso-8859-1')
msg.attach(inner)
msg.add_header('Subject',str(Header(subject,"iso-8859-1")))

# now the attachments:
for obj in context.attachments.objectValues('File'):
mt,st=obj.content_type.split("/")
p=MIMEBase(mt,st)
p.set_payload(str(obj))
p.add_header('content-disposition', 
 'attachment', 
 filename=obj.getId())
encode_base64(p)
msg.attach(p)

# now you are ready to send the mail like this:

context.YourMailHost.send(msg.as_string(),
  mfrom="Foobar <[EMAIL PROTECTED]>",
  mto=["Someone <[EMAIL PROTECTED]>"])

I wonder how DTML is more easy then an equally simple
python expression in a script?
Lazy people should love ZPT since it saves a lot of typing
compared to DTML - otoh, a general rule seems to be: beginners
tend to write overly comlicated code.

No, it will not phased out. Neither in zope2 nor in zope3.

Which version did you install from source? Are you using the
debian version yet? If not, just apt-get remove --purge zope
first to get rid of all debian traces and then remove 
the zope where you installed it. (Should really be just one
directory for the zope and one per instance depending how
you installed it.)

Use:

return sequence.sort(files, (('bobobase_modification_time',
'cmp','desc'),))[:3]


[:3] is a slice operator which returns

item0...item2

since you sorted descenting by modification time, the
first 3 objects should be the most recent 3.

beside the fact its a not really public attribute, it isnt

The ical module from mxm can be used by own code

You do this all in the Filesystem where Zope runs. Hence the name:
Filesystem based products :-)
As oposite to creating objects thru the web. (Which are of course

Of course does read() return all the data in one string - the python
documentation leaves no doubt here.
You might consider reading in chunks, encoding them while you send
and if validation is successfull, rewind by file.seek(0)
and then manage_addFile() directly with the file object.

Timeout can be an issue with large files and when the remote
server is slow. In this case, you can send some data to the 
clients browser while you work, via context.REQUEST.RESPONSE.write()
Note: once you start using response.write() you cannot use return()
in your script - at least the user wont see any output from it.
You also should catch exeptions and provide meaningfull output
when they happen since the usual exeption handling will work but
the user wont see its output.

There arent. Neither commercial nor free. Dont think pop3 is 
interesting anyway. I think I saw some IMAP code but I dont know
where. Just feed your search engine of choice and be prepared
to find only fragments.

Sure it would be interesting to have an IMAP server just like
the SMTP server and let them play together. From what I know,
nobody had the time yet.

If you find something interesting, please let me know :)

Where I use it and it works is an early 2.7ish. 

Yes I know I should update, but if you did some hacks here and
there (notably removed the hard coded latin-1 every time
you download a ZPT or python script) ... is a greater effort ;)

I dont think this is the way round he wants ;) 
At least there would be ready to use webmail products which
are available for zope :-)

As I said, zope as imap server would indeed be interesting :-)
Its only a fairly bit of work since the protocol is a bit weird
and the usual clients even more.

No. They look like dictionaries, but they are not dictionaries.
You used :records, which gives you lists of record objects.
You can copy to a real dictionary to do what you want.

Zope on windows is packaged with own and right version 
of python, which is 2.3 for all current Zopes.

So you need to use the package for python 2.3
and not 2.4. Next, since zope has own python,
you either copy the module to zopes python
or change startzope.bat to refer to your
installed python2.3.

You cannot just point to or use 2.4, since 
zopes extension classes are compiled for 2.3.

For me, it looks a bit like:

def pyUpdate(self,REQUEST):
 fields=REQUEST['fields']
 x=REQUEST['x']=fields[0]
 y=REQUEST['y']=fields[1]
 x.balance=5000
 y.balance=5000


I dont think the loop above makes any sense :)

The common idiom goes like this:

results = [{'balance':balanceexpression(item),
'lastname':item.lastname,
'name':item.name}
for item in context.SomeZSQLMethod()]

for example.

For more advise I think we need the big picture (in english
words) what you are doing here.

Well in fact there is development towards
2.4 but it will take its time to become
stable and secure. Zope security depends
much on the specifics of python and newer
versions may have differences there.

Zope has along with nice type converters, also a workaround
for the checkbox-problem:

However, working with request.form.get('value',default)
is often more robust.

You can enable profiling (see ZMI in Control_Panel)
(You need to create a file for the log in the filesystem,
change config and restart zope) where you get refcounts on
all object but it will also cause substantial slowdown.
E.g. nothing you use in production environment.

Next best be it to just analyze the logfiles, for example
Z2.log - which gives you numbers based on URL
(Not that in a publishing process not only the object
on the specific URL is used but also a lot parent objects,
user, etc.

I guess it highly depends on what you really want to do.

request has a lot URL variables you can use.
However zope usually does the right thing [tm]
here - you should just design your links
carefully. E.g. use root-relative, that means
links that start with / all the time.

Not at all. You could either have tried

If you are learning anyway, why not skip the DTML

You cannot simply pass a ZOPE object in a form like that.
You can handle fairly complex structures (lists and dictionaries
with int, float, string in them) but whole objects would
need to be pickled and then open a huge security hole
(Whatever is in the client can and will be faked)

So best option I see is to not pass the object but rather
pass the reference to the object. You can resolve
it via restrictedTraverse('/path/from/form')

Btw. avoid much code in the Template. Its a maintenance
headache. You can do it esily in a python script and 
call this from template.

Well yes, thats very easy. Just store your (compressed or not)
HTML data (since its a string after all and not such a complex
object) in a hidden form field (base64 encoded for example) ->

filedata=htmldata.encode("base64")

and the other parts of your form as you wish. Maybe you prepare
the data in a script and call the ZPT from it:

return context.yourZPT(filedata=filedata,somestatus=whatever)

and use:  in your ZPT.

When the request returns, use: htmldata=filedata.decode("base64")

alternatively you can just store the data in REQUEST.SESSION
to keep it on server (but watch the memory usage)

Well err. You have got all possible solutions: create object in ZODB 
and pass references around, create object in session (which is easy, you
just store the string with the data) or send the data in the form
between client and server. (Your error you mention above indicates you
did not really create an object or used atomic datatypes)

All methods have drawbacks and advantages. Despite of having the user
select the same file again to send (which would be the 4th solution)
there is none left. This isnt genuine to zope but inherent to all 
solutions which work over HTTP.

I'd suggest to skip the 2-phase upload in favour of a one shot
with all the relevant data. E.g. "[ ] check here if you want
this and that" in the same form as the file gadget.
Especially if the files are potentially large.

IIRC. you can just use

I know of no occurence where you have either \n or \r
but in the same string (and not just \n or \n\r)
But if you want to replace each, either:



or



but beware the quoting.

Even better maybe you just use CSS for your layout:





or with ZPT:

I use it but in a very hacked up form because I need inline auth

Well this sha1 patch wasnt the real hard work ;-)

Inline auth was the real nut to crack. And the fact XUF returns HTML
instead of using appropriate exceptions add to the complexity :-)

I hope PAS will fill the gap although it isnt yet ready for prime time.

Stop. Should Interbase here behave different? Its actually required
that a database makes changes visible to all queries in the _same
transaction_. It depends on Transaction Isolation Level 
if you see further changes, e.g. if your Database supports "read
committed" - this means you would see data changed by _other
transactions_ that started _after your transaction_.

Thats weird. I'd like to see the model you are referring to here.
Are you perhaps playing with after-commit triggers?

+1 this is also my understanding judging from the messages flowing
around. 

The statement of ZC indicates they want to transfer their trademark
to ZF and now find the european trademark in other hands. OTOH, why
not just transfer/licence what they have (the .us trademark) and
just agree to ZEA transfer/licence the european trademark to ZF
too? 

As I understand, the benefit of a ZF with the source in the hand 
would be to help contributors to defend against patent issues
which you probably cant avoid if you do any development.
So I really like to see ZF founded as soon as possible.

So please ZC and ZEA come together, the community really wants
it. 

May I suggest to create a temp not-public-archived mailinglist
to further discuss this issue?

Session is still the best thing you can use in this case.
Note that HTTP is stateless, you just dont know when
a user "logs out". - unless she is so friendly to use
a button on your site where you can trigger to delete
the session and auth cookie.

runzope or zopectl fg 
are good for testing if the installation works
because you get all the messages on screen (like you show below)

zopectl start 

should be used in production because it detaches zope 
from the shell. I think the INSTALL.txt section
needs some clarify on this - although zopectl
gets mentioned there:

"""
Starting Zope

  Once an instance home has been created, the Zope server can now be
  started using this command:

/location/of/zope/instance/bin/runzope

  If you get errors indicating that addresses are in use, then you
  will have to supply arguments to runzope to change the ports used
  for HTTP or FTP. The default HTTP and FTP ports used by Zope are
  8080 and 8021 respectively. You can change the ports used by
  specifying the "port-base" parameter to runzope.  For example, to
  run Zope on ports 9080 and 9021::

./bin/runzope -X port-base=1000

  There is also an interactive Zope command shell named 'zopectl' that
  may be invoked by running 'bin/zopectl'.  By default, 'zopectl
  start' will start a background process that manages Zope and
  'zopectl stop' will stop the background process.

This is not a command. This is a method!
Methods are called "on" an object.

so if o is your object,

o.bobobase_modification_time()

returns the internal storage time of that object.

Maybe its a good start if you read the python
tutorial (www.python.org) to get an idea on all
that object, method, attribute stuff.

It looks like this part of the Iterator is just misdesigned:

def next(self):
if not (hasattr(self, '_next') or self._prep_next(self)):
return 0
self.index = i = self.nextIndex
self.nextIndex = i+1
self._advance(self)
return 1

IIRC, ZTUtils were written long before the python iterators became
standard. So the method name next was used and now clashes with
the standard iterator protocol.

It could be fixed but only if there is no product in the world using
it or all must be fixed before.

I propose: has_next() or something in place of it.

Yes, you should write HTML when you want HTML ;)
This means, attribute values in HTML are supposed
to be in " "
(See the HTML source in your Browser when you display
the page and you will know what I mean :)

So, if you really want DTML here, use:



or 



which is a bit nicer because you dont write a tag inside
a tag.

OR use ZPT:

This is not a good idea anyway.
1) it lets every user knowing the external method
   connect to every database on your host (depending 
   on credentials if any)

2) even worser it enables the user to issue any
   raw SQL string to the database, including but not
   limited to DROP table; DROP database; etc.

3) by not using ZOPEs infrastructure (read: Z(yourdb)DA,
   ZSQL-Methods), you have the expensive connect operation
   every time, loose the ability to easily work with zopes
   transactions, have to quote and unquote values and so on.

So get a ZODBCDa or something like that and use it.

here you would write:



because your external Method does not magically

I'd suggest to actually store your objects to find out.
But storing is only half the work. Retrival and update,
as well as schema extension, concurrency etc. are more
interesting. Just storing means a plain mmapped file will
sure outperform any RDBMS :-)

And also see if you compare the actual interface speed, meaning
if you plan a web application on top of your data, do the measurement
on the resulting web app and not the bare storage.

Copy the output of the complete  directive.
I dont know if its missing or you forgot to copy but
from above there is no RewriteEngine on statement for example.

Also output of apachectl -S or httpd -S (depending on the version
of apache you use) would be helpful.

Looks OK for me. A bit more complex then you need for just the VHost in 
Zope due to your logging rules but it should work.

It depends on your installation, httpd is the binary which is
the apache usually. Where it is you have to find out yourself.
(/usr/sbin, /usr/pkg/sbin, ... whatever)

In any case you should make sure you reload the config in 
apache. usually this is done via apachectl.

-S should print out the virtual hosts as seen by apache.

Argh. You are on unix. Nobody reboots a unix box :)
You did not tell us which OS (linux? And which distribution
you are using. Its hard to guess from here. It looks
like its Apache 1.3. Often the binary was called httpd.
It could as well be just apache. I really dont know what it
is on your site :) Chances are your config is just not
included. Are you faced with one single config file?
Or are there many single snipplets?

Nono! You dont configure anything in the VHM object!
All its needs is done by your RewriteRule above.

When it works, you are already inside the "folder"
/conturionsecurityvi.com

(if you are using excatly this folder name - check
by visiting your zope instance directly)

Hm. You can perfectly run a source build of Zope on package-python
from debian. Testing has 2.3.5-6, which is perfectly usable.

Thats why I'm using debian too - to save me from all the hassle with
source depencies while using source where I really want it :-)

You will see this in the list archives several times in the past.
Depending on the object, id is a method and not an simple attribute.

To be on the save side (instead of figuring out what it is actually)
always use: getId()

Btw.  does not use the id the same way like 
. Try  and you will see
the method signature (view document source in the browser)

I'd recommend doing that all in a python script and then
use the prepared data in your DTML - oder later ZPT.

Use http://127.0.0.1:8080/ instead to access your zope.

Now you know why right above the mappings window
there is this line:

"If you place the hostname that you use to manage your Zope in this list
you are likely to regret it, and will probably need to manage Zope using
its raw IP address to fix things."

with "you are likely to regret it" emphasized :-)

If you want to try real world mappings, put some
names in your hosts file and use them for experiment
instead.

Yes. See doc/INSTALL.txt :-)
One of the points is you compiled your
extensions for python 2.3, and therefore
you need 2.3 to run it.

No it cant - you cannot use it to obfuscate text
like your captcha product seems to do.

But some people are using text-to-image products
to render buttons and this is where you can
use CSS instead.

Btw. Text-to-image obfuscation makes it harder for
machines to automatically fill out forms but not
impossible.

webdav works over http - yes, the same http your browser uses.
Apache handles this fine. Nothing to do.

Ah so. I use webdav over the standard port and not unsing the separate
webdav only server.

ZServer handles webdav just fine.

Oh, its not that hard either, you can use apache as proxy for
any host:port combination. That means if you really want to
use the separate zope webdav daemon, you can use another
hostname, say https://dav.yourdomain.com/ to
proxy to zopeserver:webdavport
or https://yourdomain.com:8443/ - which works
too (and has the advantage of keeping the ssl-certificate
valid)

You could just wrap it in a simple python script:

results=context.yourZSQLMethod()

h=results[:1] # see python slice
b=results[1:]

return context.yourPageTemplate(header=h,body=b)


And in your ZPT use tal:repeat="chead options/header"
and options/body

But maybe you can rething and rephrase your problem :-)

I believe Zopes VHM is the very SEH but updated since it became part
of zope. In recent zope versions there is in fact nothing to do to
use it because an instance is automatically created.

Actually this is a bit dangerous if you dont lock

You dont need a real (filesystem-) file if all you want is sending it

The example above is unfortunatly a bit bad from app design view.
You should either do the comparison in your ZSQL Method
or wrap the call to the ZSQL method in a simple python script.

Then all your ZPT reduces to:


  Example 


Which is imho much better to read then the code above.
All you need to do is to deliver True/False, None/Something
for the "selected" field. 

Not doing the comparison in your Template (no matter if DTML
or ZPT) really makes live easier.

You should try to get your Application right independend of
any HTML output. (e.g. you can call the scripts/ZPTs directly
to find out whats going on)

Well, you are right. I do not directly call the modules's function from

Dont do that. Use a Database adaptor instead - any maybe issue
the query there if you dont want the ZSQL-Resultset-wrapping.
The reason is, ZDAs take care of pooling and so on and you avoid
a per thread reconnection.

Then put constraints in on your database, or make the whole connection

Usually you dont want that. Sane security constrains on database save
you a lot mistakes if done right. You can also use views and stored

Bad done external methods are more likely to open security holes.

You'll have to add code to your script to order the form items yourself.



 But the thing is that I don't have guarantee that user will not replace

And how exactly would that help if your script isnt expecting the new

I'd use the :list and :records modifier accordingly for keeping

The fileupload object is simply a file. (can be cStringIO, 
can be tempfile - depending on size)

Best is to do so:

maxsize=1<<20 # 1MB

fu=context.REQUEST.get('fileupload') 
fu.seek(maxsize)

if fu.read(1):
raise OverflowError("File too big!") # or something like that

fu.seek(0) # rewind to start

filefolder.manage_addFile(...)


This avoids loading the whole file into memory to find out.

Well, you could (and should!) study the python documentation.
But this one is only an example. You can write the maximum

If you have an imagination of what value you want, just write it

Re: [Zope] REQUEST.form variables order

[Tino Wildenhain]

...

And how exactly would that help if your script isnt expecting the new
fields anyway?

I'd use the :list and :records modifier accordingly for keeping
ordering where that matters.




The thing is that there is possibility to change fields order by the mean of
WYSIWYG editor by the user. If he change order I would expect to get the
same order in REQUEST object.


You cant. If you need to maintain order of fields, use :list or :records

e.g.



and so on.

Then you get a list for field and the elements are in the expected order.

You might read on that matter a bit:

I fail to see how the zope could possibly influence the rendering
of the very same HTML in a browser. 

Probably best would be to check both HTML sources as they are
delivered to the browser - as well as maybe mime-type and charset
in the header (via headersniffer-plugin in firefox or tcpflow or
similar)

Maybe you changed something with the update? Are you using
some framework on top of zope?

Tino.

Ah yes, well, zope2.6 it was. Otoh, if he would inspect the source
it should show up :)

Would not affect lynx but should otherwise work :)

This isnt that bad - you just get a bounch of insert statements
which should work.

SQL knows no list, so the above is probably best you can do.
Otoh, you could manipulate the values as ARRAY and use the
database functions to select from array to table - depending
on your database.

You should get into the habit of specifying the column names
literally to avoid changes of order and case of your columns
as they come from the database. Also you dont retrieve columns
you might not need (if you extend the table later).

Write AND instead of && - && isnt SQL standard and makes it harder for
you to change the database.

> Is there a way to marshall the results of this ZSQL object back into a list?

ZSQL objects is a bit confusing. You probably mean the DTML elements of
the ZSQL Methods. As I said, there is no list in SQL and Array
is a bit specific to databases. For example you could do something
like



would render '{1,3,4,5,6}' to the database which in Postgres would
be an array.

You should be able to optimize this by means of stored functions in your
database.

Maybe this can screw things even more. I think we should remove the 
ability to add more VHM instances once one is there (and with recent
zopes you already have it on install in the root)

The VHM management tab has all the info you need. In fact, the example
there is:

http://localhost:8080/VirtualHostBase/http/www.buystuff.com:80/buystuff.com/VirtualHostRoot/$1

Which would translate to:

http://server-your-zope-runs:8080/VirtualHostBase/http/example.net:80/plone_site/VirtualHostRoot/$1

Make sure you have only one VHM object and it in your site root.

> Is there a shortcoming in the documentation here?  Have I accidentally

I suspect there is a bit confusing documentation out there which isnt in
sync with the current implementation. In case of the VHM its quite good
documented in its management tab. Maybe we should uinify the places 
where one can find up to date documentation.

Yes they do - unless you muck around with it ;)
Are you sure you dont have a ghost virtual host
monster somewhere in the path left?
If you dont yet have content, try with a fresh
Data.fs, dont install/change anything in/with
VHM and use your Apache config as we had
last time. It should just work.

as root, su zopeuser first and then try your script.
Zopeuser meaning the user account your zope runs.

Modules for python to work with GIS are usually integrated with
specialized backends, such as ArcView and friends.

I've never heard of anybody trying GIS with zope.

Its seems you are the first here :-)

I'm not saying its impossible, but you might have a lot of
work, as learning the fileformats, build parsers, create
transforming objects maybe using PIL, create specialized
index for ZCatalog and so on.

Good luck!

Seriously, what should we do to help you? If something isn't

Well no, at least not your "it does not work" problem you told us.

Still missing: the call to the script as "User which runs zope"
which might be zope or nobody or something, depending on your
configuration and the way you start zope.

Add the following lines to your external method and you can
run it as script too:

if __name__=='__main__':
   import sys
   try:
user=sys.argv[1]
pass=sys.argv[2]
   except IndexError:
sys.stderr.write("Please start me with %s  
\n" % sys.argv[0])

sys.exit(20)

addUser(user,pass)



and try it like this:

su zope (or whoever your zope runs)
./yourmethod.py someuser somepass

You will see it fail (apart from the fact you need
the #!/path/to/python.bin and set the execution bit
with chmod a+x before you try)

Because you did not use sudo as adviced.

Please try to copy the way mails are cited from other
