string to objectname conversion ?
by Gijs Reulen 08 Aug '00

08 Aug '00

Hi I would like to list all objects in a folder. No problem there. However, I want to use the function/method universely so I need to pass the name of the target folder; as a string is the only way I can think of (formatted as a url). I tried several things in DTML and studies the DTML Ref, the mailinglist and the How-To's very hard but did not have the Enlightment yet :-( Is it possible ? Example: <dtml-in "PARENTS[0].objectValues()"> <dtml-var icon> <dtml-var id> <dtml-var title> <dtml-var meta_type> <dtml-var bobobase_modification_time fmt="%m/%d/%Y"> </dtml-in> But then instead of PARENTS[0] some parameter, for example: /method?folder=foo Gijs Reulen

SQL Query -> DTML Form with populated values -> SQL update example??
by Bill Broadley 07 Aug '00

07 Aug '00

I'm fairly new to Zope. I have various view, search, and insert into a SQL database (MySQL) working. I'm having a problem connecting all the pieces for an update. Does someone have an example (with DTML or similiar source) that demonstrates the following: 1. A search field for record id, or a list with a clickable URL for each record (that is the result from a SQL select) 2. Allows updating of the record with a DTML form with values already populated 3. An SQL update based on the values from #2. I checked the ZSQL pdf, and the giant HOWTO collection without finding a good example. Any help appreciated (including documentation references). Many thanks, -- Bill Broadley

Using absolute_url you are acquiring it into your Instance URL, which is not necessary (and will hamper off-server caching).

I created a ZClass subclassing CatalogAware and File. I added a property called text which is text indexed in a catalog. When a Word document is added, a method I created uses the wvHtml utility to convert the Word document to text and store it in the text property. It has kind of a kludgey implementation at the moment, mostly because I want to create a Python wrapper around the wv library, but it's documentation is sketchy and I have other priorities at the moment. It does work though and lets you search Word documents using a ZCatalog quite effectively (although it only works for Word docs).

Can ZClass products use structured text?
by Jeff Sasmor 07 Aug '00

07 Aug '00

Zopeistas - I am trying to use the new help system to add help for a product (finally) newly-adapted to Zope 2.2. When I imported the ZClass (.zexp) file, I noticed a nice Help folder, and I can see how to add help topics and how that works very nicely thankx. However, it does not seem possible to create a stx document from the web interface, if only to be able to have help pages that more or less look similarly- formatted to the ones that are part of Zope already. (In desperation I just tried using structured text in the help file with no success.... didn't really expect it to.) I suppose that one could use a kludge and have the topic just open an dtml doc with fmt=structured_text. It would be nice to just have a .stx file as a normal product does (you can see this by looking in the help files for 'regular' Python products. Perusing the source, I see in lib/Python/HelpSys/HelpTopic.py a class STXTopic (line 264) that's a subclass of TextTopic, but I don't see a way to create one of these from the web. Am I missing something zymosely obvious? TIA, Jeff Sasmor jeff(a)sasmor.com

OK, so let's answer my own email in case somebody comes into the same problem one day. I changed my configuration to use IIS instead of Medusa of the front end. Since then, everything is fine.

I only had a few problems for the authentication. To be able to use Zope for the authentication, make sure you allow Anonymous login and that you set all the "Custom Errors" of IIS to default. Else you won't be able to log into Zope management screen for example ;-) >As I am with the Win2000 questions, is there a way to configure IIS to >behave like Apache an the rewrite rules?

I did not read this How-To. Thus, be careful with my explanation. A mutable object is one that can change its value over time. E.g. a list is mutable (you can "append", "insert", "delete" elements) while a tuple is not. If several threads concurrently access a mutable object (or a mutable binding, i.e. a name (variable) is bound to different values over time), results can be quite unpredictable. Usually, you would use a synchronization mechanism to control access to objects. See the Python modules "thread" and "threading" for functions available for this purpose. > If global variable is not permitted, how can I approach thread > programming in Zope? Without global variables, how can I control > threads? You can use global variables -- provided you know what you do and ensure proper synchronization. You may want to look at "ZODB.Transaction.get_transaction" to learn how Zope itself manages its transaction context in view of serveral threads. Dieter PS: I do not like MIME messages in this list. The list software strips MIME headers and my mail reader is therefore unable to decode the message.

"_[xxx]" executes (calls) the retrieved object, if possible. In your case, execution calls "RESPONSE.redirect". You need "_.getitem(xxx)" instead of "_[xxx]". This only retrieves and does not call the object. Dieter

I expect you to have a misconfigured selection property somewhere. Dieter

PTK Member-Folder Object Properties (phew!)
by David Riggs 07 Aug '00

07 Aug '00

For each member in the Portal ToolKit, a folder is created in the folder 'Members', i.e: ZopeRoot/Portal/Members/member_name I've created a ZClass called Customize that has several properties, and I've added an instance of Customize (and called each instance Customize) in each member's folder. i.e.: /Portal/Members/member_name/Customize What I need is a way to access the value of these properties for any given member that is logged in at the moment. In other words, I can do this... <dtml-var "_.getattr(Members.member1.Customize, 'some_property')"> and get the value that I need for member1. I want the equivalent of replacing 'member1' with AUTHENTICATED_USER.getName()...I tried substuting it in and building a string with it, but that causes getattr to complain about strings not having the needed property. Any ideas on how to make this work, or ideas on how to do it a similar (or even completely different) way?
