You probably will need a Zope product called SiteAccess. With "SiteAccess" alone, virtual hosting would have been a matter of about 1/2 an hour. With Apache (ProxyPass) and SiteAccess, it was a matter of about 1 day. This should now be a matter of parts of an hour, too, because a contributor wrote a HowTo, how to patch Apache to let it propagate HOST information. > - how stable is Zope regarding to Apache on Linux ? Sometimes, images must be forced with a SHIFT-reload to be shown correctly. I do not know of other problems. > - we have a MySql database, is it easy to connect with Zope ? Yes. Install MySQLDA. Then it is as easy to connect to it as it is to connect to any other relational database: add a connection object to a folder. > - can I access the Zope internal database with e.g. ODBC ? No. But you can access it via HTTP, FTP, Webdav, XML-RPC and soon via XPath. > - can I use log analyzers to get some statistics about our site ? Zope's logfiles are compatible with (e.g.) logs written by Apache > - any advice about migrating an existing site ? Where do you come from? What special features do you use/need? What techniques do you use now? How many script do you have? Dieter

File upload objects can be used just like files. In addition, they have a 'headers' attribute that is a dictionary containing the file-upload headers, and a 'filename' attribute containing the name of the uploaded file. Consequently, you will use <dtml-var "file.filename"> Dieter

Re: [Zope] ZServer stepping on Content-Type and Content-Length?

Instead, the "HEAD" method from "webdav.Resource" is called. It uses a "content_type" and "get_size" attribute/method to set the "Content-Type" and "Content-Length" HTTP header. If there is no "content_type" attribute/method, the content type is guessed (via "mimetypes.guess_type"). If there is no "get_size", the "Content-Length" is 0. Dieter

ZCatalog and foreign characters
by Radim Gelner 29 Aug '00

29 Aug '00

Hello, is it possible to make ZCatalog work correctly with words containing characters other then those given in ISO-8859-1. Now, it reports "no found" for all such queries even when these words are present inside the documents on site. Thank you, Radim

Re: [Zope] How to get URL of folder (name unknown) with a certain property?

Tim Hicks writes: > I am trying to figure out how to get hold of the URL (using > absolute_url I presume) of a folder with a property called > "sehs_root_folder" set to "yes". Have a look at "ZopeFind" (it is the function implementing Zope's "find" tab). It is documented in the Object Reference (--> zdp.zope.org) maybe in the Zope 2.2 help system, too. You need to use a relatively new Zope (2.2.1), because older Zope installations raise unjustified "Unauthorized" exceptions due to a bug in "ZopeFind". Dieter

SQL question...I think
by George 29 Aug '00

29 Aug '00

I know nothing about sql so forgive me this idiotic question:-) All I know so far I had learnt from ZOPE tutorials and HOW-TO's. Here is the question: I have a database connection working. I created a couple of tables and filled them up with stuff. I know how to insert data in to the table, search and such. I can not find any info on how to embed the data in my dtml-html code to show it to the world. I know how to create a form for the visitors to search for the stuff. What I need is simply include some data in my documents without any interaction. If I have for instance a table that contains a columns: product_id, price, weight. How do I display the values one by one? (not the whole table) I have some data in the table that I do not want to display on every page. Can I choose just one row and column and display just that data in that single cell? Say only the price of the product number 00001? Regards, George

RE: [Zope] Wanted: Procedure to produce binary release from sourc e release
by Brian Lloyd 29 Aug '00

29 Aug '00

We use a script that basically pulls binary files out of our CVS repository - I dont think that would be very useful to you :( This should be pretty easy though - I would suggest making a little python script that makes use of the install machinery that's already there in Zope (w_pcgi and wo_pcgi are just thin wrappers around some of that machinery). For example: # builder.py - untar a Zope source release, cd to the # top directory of it and run this script. It will build # all of the binaries for the current platform - you # could easily extend this to tar up the result, etc. import sys, os def main(dirname): # add zope install helper modules to path sys.path.insert(0, os.path.join(dirname, 'inst')) # build pcgi import build_pcgi # build pyc files (could be skipped if you want) import compilezpy # build the extensions import build_extensions if __name__ == '__main__': main(os.getcwd()) Hope this helps!

Re. Advice for new zope installation

Henk Schets wonders: > - how easy and reliably can I manage my virtual hosts (about 8 sites right now) ? Very important. The SiteAccess product contributed by Evan Simpson is a popular solution. http://www.zope.org/Members/4am/SiteAccess2 > - how stable is Zope regarding to Apache on Linux ? That's how "the Zope Folks" at Digital Creations run Zope, so I'd guess it's about a clean as can be. However, there is more than one approach. Probably the easiest is ZAP, which comes with a preconfigured Apache. http://www.zope.org/Members/michel/Products/Zap Start here: http://www.zope.org/Members/guy_davis/install_routes Below is the tip of the iceberg from a search on "apache", at Zope.org http://www.zope.org/Members/shaw/HowTo/ApacheFrontEnd http://www.zope.org/Members/nemeth/howtos/zopeandapacherh61 http://www.zope.org/Members/anser/apache_zserver http://www.zope.org/Members/michel/HowTos/ApacheRewriting http://www.zope.org/Members/kedai/apache_zope_fcgi > - we have a MySql database, is it easy to connect with Zope ? Lot's of folks use MySQL with Zope, and there's a ready made "DA" (database adapter) just for this purpose. http://www.zope.org/Members/mordred/ZMySQLDA > - can I access the Zope internal database with e.g. ODBC ? So far, no. New and interesting ways of storing Zope Objects are being developed though, so let's not count this one out. - can I use log analyzers to get some statistics about our site ? Zope does do some logging, but I don't know much about that. Maybe someone could answer? > - any advice about migrating an existing site ? One handy item that I have used is Jonathan Farr's LocalFS. This way you can keep serving static pages and images "directly" from a local file system, and frees you to decide when the time is right to turn all those icons into Zope Objects. http://www.zope.org/Members/jfarr/Products/LocalFS Also, leverage your MySQL for all its worth. The more stuff you can abstract into tables and treat as lists, the more you'll like Zope! Later, Jerry S.

Hello, few weeks ago, on Zope site I came across a document describing how to build news section with features like displaying with five most recent items from a folder, etc. But now I can't recall, where it was. Can someone point me in a right direction. Thank you, Radim
