Re: [Zope] dedicated folder for each user

In general, you can do anything programmatically that you can do with the management interface. Because Zope is open source, you can learn from the management interface, how to do it. You take the following steps: * locate the source for the form that asks you for the required information. In your case, this will probably be a "*.dtml" file in the OFS folder. * Usually, the form "action" tells you the function/method that performs the operation (after the form is submitted). Sometimes, the function/method is given by the button name or button value (if the name end in ":method"). * If you are lucky (most of the time, you will), then the function/method is documented in the object reference (-> zdp.zope.org) the Zope 2.2 online help or the interface Wiki (-> zope.org -> WikiCentral). * If you are not lucky, you can derive the function/method interface from the form variables. The request object contains variables for each (most of the) form input element (maybe with ":<type>" suffixes stripped and executed). For your special task, you must also know, that the logged in user is described by "AUTHENTICATED_USER" and that this object has a method "getUserName". Dieter

Start with -D option #2. Use the PythonWin to run your changes through a tab nanny. (Side note: edit.com messes up the tabs in the python code badly, use notepad if you really have to), before restarting. #3.

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.

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

Re: [Zope] Showing the name of a file-type form variable

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!

CatalogAware
by Yapo Sébastien 29 Aug '00

29 Aug '00

Hi ! I use objects from a class which inherits from CatalogAware. The objects index themselves into the ZCatalog but I get strange results when I try to search in this ZCatalog... The problem is solved after reindexing the object via the reindex_object() method but this works only for manage_edit ... I can't index my object properly in the manage_add method (I get the same problem) Newly indexed objects seem to be added to the ZCatalog with the indexes from the previous cataloged object (or something like that) Is there a bug I should be 'awared' to or am I doing something the wrong way ?
