[Zope-dev] How-to : Defining custom DTML-tags ??
I want to create a custom DTML-tag. How/where do I start ? My goal is to create a way to define a form and validate the input ( that integers are valid, required fields filled out etc. ) using Javascript in the browser and and on the server side after posting. Any thoughts ? I was thinking something along the lines of : Python Perl C Any info on how to define your own custom dtml-tags *in python* would be highly appreciated. Anyhow, if the functionality I'm looking for is somehow allready available I'll consentrate on something else.

[Zope-dev] Project manager ala Sourceforge in Zope ??
Hi, I need something similar to Sourceforge ( project manager with docs, simple bug-reporting/issue-tracking, release-manager etc. ), implemented as a product in Zope. The zope.org-homepage has something similar. Is the code available? Does anybody know of any product like this? I'm just getting started with Zope but has several years background in Python. What would be the best way to develop a product like this from scratch ?? Any comments, ideas or people who want to participate in a project like this, please contact me.

[Zope-dev] Indexing/Searching lots of XML-data
Hi, I got alot of XML-files I want to publish using Zope.

[Zope-dev] Urgent code-review: code works on win2k, fails on Linux
I try to extend the ftp-server ( and http-server, but that works fine ) in
Medusa/Zope to fit into a project I'm working on. The following script
works fine under Windows2k, but it fails under Linux giving me a
IOException when it tries to open the file I try to upload for writing. A
ftp-client says the current working directory is "/" after login, which the
user off course doesn't have write-access to, but I cannot seem to get the
ftp-server to start in the right folder. I don't even know if that's the
real problem ...
What I need is a ftp-server that receives files of a specific type ( based
on extension) in a specific folder built from FTP_FOLDER + username. That's
it. No listing of files, no making of folders, removing etc. It's suppose
to plug right into Zope or Medusa and so far everything works great, but
only on Windows, and the final product must run on Linux.
Sorry for posting something this big, but I'm desperate.
Thanks.
Best regards,
Thomas Weholt

[Zope-dev] Writing my own request-handler
Hi, I want to write my own request in Zope. I want a specially formatted request or a command to be intercepted and processed by my own modules. If the user tries to access a url like http://www.myserver.org/myhandler or using a specific port on the server Zope traps this and my request_handler sends data back to the user based on the url . Why? I got a PostgreSQL database as a backend for a huge information organization project. I want to serve xml using a fast and stable solution like Zope or Medusa to do this, since I also need ftp for object-uploads, allthough these are not stored in ZODB. A normal ftp-server is used, and hopefully I could set up a normal medusa kind of ftp-server on a given port to do this, and avoid all the files being stuffed into the ZODB. I got a lot of non-Linux ( therefore as far as a know, non-postgresql-python users ) so I want to give them xml to process using a know protocol like HTTP. How can I write my own class/handler that traps this and serves my data ? I really want to use Zope cuz I use it for the rest of the site. I cannot serve all the postgresql data using plain zope-database methods cuz I want to write several clients in other programming languages that can receive and process the xml-format I use. The thing I want isn't xml-served as html, it's xml served to non-browser apps using HTML and ZOPE as means of delivery. Of course all of this is to be written in old-fashioned python, no Zope-products. Any hints, tips or guides is highly appreciated. I've looked at the Medusa source and found a couple of things that nearly does what I want them too, especially in the script_handler_demo-folder, but I'd like to get the whole thing into Zope if I could.

[Zope-dev] How can Catalog index all parts/words of a attribute
Hi,
I try to use Catalog with a object stored in ZODB3. I need to match single
words in attributes in what might be a long string with several words in it.
I've tried to set "self.cat.addIndex('name' ,'TextIndex' )" which is
supposed to be full text searching at least said to be in the Zope-pages
when creating a catalog in Zope. But when I try to search for objects they
only return stuff if I enter the entire content of the attribute in
question, not parts of it. This is not a Zope-product yet, but a foundation
for a future product. I'm working on a full-text searching command-line
interface, so nothing of this can be done thru Zopes web-interface at this
point.
the code has been posted earlier, in "Now; - problems using ZODB/ZCatalog in
Python". Any quick hints?

[Zope-dev] Now; - problems using ZODB/ZCatalog in Python
First off, sorry for posting a huge, stinkin' post like this, but instead of
posting ten times trying to explain what I do, I post this once and hope
somebody can point out what's wrong and I'll leave you all alone, at least
for a while.
The example is from the Catalog outside Zope-tutorial available at Zope.org.
I'm using Zope 2.2.0. This might have been written for Zope 2.1.6. I dunno.
I understand the error message, just don't why it is raised. If I should
call some form of commit() or close(), where should this be done?
And, by the way, does Catalog support different kinds of searches, like
matching all the search-words, some, does the order count ? Can this options
be set, if any exists?
Anyway, thanks for your patience and bandwidth.

[Zope-dev] Use ZODB3 and ZCatalog for indexing purposes
Hi, I'm wondering about using ZODB3 and ZCatalog for a CD-indexing project. The actual cd-roms will seldom change after they've been registered, and I'd like to have some sort of auto-full-text-search feature. How does ZODB3 and ZCatalog fit in this picture? I'm NOT making a Zope-product yet, just a plain python-script, using ZODB/ZCatalog for storage. Later, the thing will have a Zope-interface, but for now I'm having so much trouble with my current implementation using PostgreSQL, mostly due to the fact that I cannot get full-text-searching, that I really need some progress now. I'm dealing with plain python objects the entire time, but searching is alpha/omega in this case and will break it completly if not implemented correctly. Any hints, tips, flames or just emails sent out of boredome, I'm a lonely coder who needs a stinkin' break before I go completly nuts, so any feedback will be great. :-> Thomas ___ 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 )

[Zope-dev] Temporary tables expire when ??
Hi, I`m using temporary tables, using PostgreSQL 7.0.2 and ZPygreSQL-DA v3.0, and in the RDBMS docs it says the temporary tables will be destroyed when the database-session is over. When does that happen using Zope? Doesn`t it hold the database connection open until it is manually closed? Can I override this, so that the temporary tables are destroyed after some time of inactivity or if the user logs off?? Thanks. Thomas Weholt
[Zope-dev] Full-text Indexing FOLLOW-UP
Hi ( again ) Wouldn`t Zope as a web-database integrator benefit from a feature like full-text searching? ( Everybody answers yes and nods. ) It seems as if Zope is aimed at information-publishing, using a RDBMS as source for that information. An initiative from the Zope community to either create products that support this using the most common RDBMS, support these features in database-adapters if the RDBMS supports it and/or create documentation ( HowTos/Tips ) on how to build a simple full-text searching, give ideas, overviews etc, would make Zope a more viable solution for information-publishing. My reason for asking this is that I`m trying to sell OpenSource to my co-workers, show that Open can be just as good as any commercial, Closed-Sourced alternative. When I said that full-text searching wasn`t running out-of-the-box I was laughed at. The solution used in my company is Windows 2000 server, MS SQL 7.0 and SiteServer/MS IIS. To compete with this full-text searching is a must. I used PostgreSQL 7.0.2 with Zope and PostgreSQL has a c-library for full-text searching included in the source. If we could get this to work with Zope we would be a bit closer. I`m going to dive into this, so if somebody wants to help, has tips or whatever, please feel free to email me.

[Zope-dev] Searching a relational database
Hi, How can I search a relational database thru Zope? ( I`m using PostgreSQL 7.0.2 on Linux ).

[Zope-dev] Zope + Gadfly = Rapid Prototyping?!
Hi, Now that I`ve a couple of SQL-methods working with Gadfly, I`m wondering if they will work without modification if I install a different SQL-database, like Postgres. Of course, that depends on SQL-syntax used and what part of SQL-standard the other database supports, but for rather simple SQL-stuff it should be ok, right? I hoped to create a prototype of my entire project just using Gadfly, with a very limited amount of data, then install a different database-adapter when it`s time to really shove alot of data into it. The queries might need optimization, but I`ll take those problems when they come. I just want to know if there are pitfalls to watch out for working like this? PS! Thanks for all the answers I got to my question about ZODB and ZCatalog, - it really enlightened me on some key issues in Zope I totally overlooked.

[Zope-dev] ZCatalog and Huge Customized Objects in ZODB
Is it possible to store lots of huge objects, like 2-3 MB in size each, in ZODB and catalog them for easy searching? Can I catalog special properties of custom objects and skip others? Are there any limitations to ZCatalog and the amount of stuff to index, before the speed is affected? If somebody has pointers on how to store custom python-objects in ZODB and make them ZCatalog-aware or somehow work with the ZCatalog, I`d be most grateful. Thanks.

[Zope-dev] ZODB3 - updated stored objects
Hi, I read somewhere on www.zope.org that each time you update an object stored in ZODB3 a new record will be appended. Does this mean the entire object will be stored in a new location with the updated values? If so, isn`t that kinda dumb, at least if there`s no way to override this "feature"? Anyhow, I want to store several big custom objects in ZODB. These objects can be frequently updated, and I`d like to update the previously stored object, not store the entire thing again. Can anybody clarify or give me hints on how to do this?

[Zope-dev] What to return to a document and how to access it
Hi,
These are defined in a product:
#---
class SomeClass:
"""DocString"""
def __init__(self):
"""DocString
pass
SomeDoc = HTMLFile('Some', globals()) # Some.dtml -> DTML-document
def SomeMethod(self, values = '', REQUEST): # the values put into the method
isn`t important now
"""Docstring"""
a = SomeClass()
a.values = {}
a.values['1'] = [1,2,3,4,5]
a.values['2'] = [323,3,4,41,25]
a.plain_string = 'test'
a.list = [32,435,21,9]
return self.SomeDoc(self, a)
#---
How can I access the returned object in 'Some.dtml'?
I`ve tried stuff like:
1: ( I want the plain_string-property of the a-object )
2: ( the same )
3: ( the same )
4.
I get a NameError and KeyError etc. It works if I return a dictionary with
keys pointing to single values, but I want to return a whole object, and do
stuff like :
#---
#---
What I want in HTML :
test
1
1
2
3
4
5
2
323
3
4
41
25
32
435
21
9
If somebody could show me how to access the stuff returned in the method
above, I`d be grateful.
Thomas
