Radio button effect for links
by Sion Morris 25 Jul '01

25 Jul '01

Hi, Can someone please help me with what I thought would be a simple problem; I would like a series of links in a nav bar to behave like radio buttons. When a page is selected the link to that page in the nav bar is deactivated and is displayed as normal text. I have tried the following in a DTML Method called 'nav'. <dtml-var id> <dtml-if expr="id='index_html'"> ## index_html is a DTML Document <dtml-var nav> <b>index page</b> <dtml-else> <a href="index_html"> </dtml-if> Even though <dtml-var id> displays the document id as 'index_html' it still shows the link instead of the bolded text. Has anyone done this in the past and is willing to share their wisdom. Thanks, Sion

Re: [Zope] Project FTP Site
by Ausum 25 Jul '01

You have in hands a nice opportunity to start using CMF, like it is right now, out of the box. CMF is a portal framework that allows their users to upload every content they want to a folder of their own, and publish what they want; and by having the Autocad drawings exposed through http and not ftp, your users will have the chance to review them online, using the browser plugin. All the dwgs (as any other content type) will have metadata to help their finding, and also all of them will be discussable, if you want it, and the discussion items will be searchable as well. (as any picture, document, news, etc, is) Doesn't it sound good enough? :) There's an issue if you don't want to use the default login manager/users base. But that's something you'll work out with the help of the list. Ausum "Montagne, Michael" wrote: > > Here is my problem: > I need to create a project site for an archiectural office.

Re: [Zope] Simple, I think!

Generally speaking, when you do a query, you want the results of your query, not just the number of records. The original poster implies that this is what (s)he's looking for. It's inefficient to do two queries when one will suffice. So when you do the following, you get the number of records, as well as the result set that can be used in a dtml-in. <dtml-let results="SQL_Select()"> #Results returned = <dtml-var "_.len(results)"> </dtml-let> However, as somene has already pointed out, it's probably best/easiest to use the sequence-length variable defined by the dtml-in. However, if someone just wants a count of records from a db query, and not the records themselves, then you're right, just use SQL.

RE: [Zope] Zope 2.4.0 on RedHat 7.0? Problems with Python module compilation and start script.
by Dunigan, Craig 25 Jul '01

25 Jul '01

> And I only just figured out why the init.d script (which I got from a > Zope-on-Redhat start-up script How-To) was hanging. The > script in the How-To > did not run the Zope start script in the background! > 'start' only needs to be backgrounded if you run z2.py with the -D (for debug) switch, which is not recommended for production sites, and (probably) why it wasn't backgrounded in the init.d startup script. The 'start' file turns that on by default, which is of course very useful while you are developing your site. In addition to backgrounding it, make sure you add a STUPID_LOG_FILE environment variable somewhere (usually in the 'start' script) so that those useful debugging messages are in fact logged somewhere, not just thrown up onto the console that you may or may not be looking at. Once your site is ready for prime time, remove the -D switch from the 'start' script, but leave the STUPID_LOG_FILE in there. It's useful for troubleshooting problems that may arise later.

File management using Zope's API
by Nicolas Villetard 25 Jul '01

25 Jul '01

I'd like to manage (create, modify, ...) Zope File objects using Zope API in Python External Methods. The only thing I have found is the API reference but unfortunately I still don't know anything about how to use Zope API... Could someone tell me where I could find tutorials or guides to learn how to use Zope's API ? thanks ____________________________________________________________________ - http://www.WebMailSPro.com - >> VOTRE service d'email sans pub avec VOTRE nom de domaine

html text entities in forms
by Mark James Adams 25 Jul '01

25 Jul '01

I have a web form where users enter plain text with HTML entity characters (the users are foreign language instructors who need to enter accented characters). When the form is submitted, the HTML entities are properly stored. However, some browsers on Windows display the entities rather than the equivalent HTML entity (ie, a with a ` above it, rather than à). I noticed that when the ZMI displays forms, it translates all the HTML markup characters into HTML entities. Thus, somthing like: <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p> This is the <dtml-var id> Document. </p> <dtml-var standard_html_footer> is actually: <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p> This is the <dtml-var id> Document. </p> <dtml-var standard_html_footer> in the ZMI source code. When "Save Changes" is clicked, Zope obviously then translates the <'s and >'s back into < and >. Similarly, HTML entities become &agrave; in the forms, but the &amp's are translated back into &'s. How would I go about doing this in my own forms by taking advantage of a functionality that already seems built into Zope? -- Mark James Adams mark(a)raysend.com

Binding Variables
by Gustavo Vieira Goncalves Coelho Rios 25 Jul '01

25 Jul '01

May some one give me a light about binding Variables in Zope? Inside a python script, when should i use context.xxx or container.xxx ? On the zope book, page 136 there is: Context The Context binding defaults to the name context. This variable refers to the object that the script is called on. Ok! So if i call a python script inside a DTML Method, the context is the DTML method, if i call the script directly by its URL the context would be the directory, right? Sorry, if it sounds to basic, but since i am a beginner i am really confused. Thanks a lot for your time and cooperation. -- A billion here, a couple of billion there -- first thing you know it adds up to be real money. -- Senator Everett McKinley Dirksen

Hi everybody, Can somebody tell me what are the different base classes that we can select when creating a Zclass ? Or is there a document somewhere ? I know that we can add some base classes to the availlable option list. So where do they come from ? Bye...

Does search engines index zope sites?
by Jan Ulrich Hasecke 25 Jul '01

25 Jul '01

Hi all! After playing around with Zope on my machine I am planning to convert one of my static sites to zope. All old static pages are well known to search engines like google. Will search engines also index a site running with zope or are there problems with dynamically produced pages? TIA juh -- Betreutes Saufen http://www.sudelbuch.de/2000/20000904.html

clean up Data.fs?
by Kyler B. Laird 25 Jul '01

25 Jul '01

I have a Data.fs that I've been building up over many versions of Zope. Somewhere along the line, I noticed that "Undo" stopped working in many situations. Now it's almost never usable. I get errors like Error Type: UndoError Error Value: Couldn't undo change to '\x00\x00\x00\x00\x00\x00\x19r' because non-undoable transaction I've also noticed that Versions can really ruin my day. I don't want to try that right now in order to give an example, but it has meant having to completely destroy the parent folder of the Version. I've just considered these as developmental bugs, but with the release of 2.4.0 today, I decided to try Undo and Versions with a fresh database. They worked flawlessly. So...I'm guessing that my Data.fs file is a bit messed up. I looked at some of the utilities, but they don't appear to be appropriate. I tried running the ZODB recovery script, but it didn't find anything to recover. I'm considering trying to export everything that I can and then import them into a fresh database. I did this long ago, but I had far fewer objects in my root directory. I'd like to avoid doing it now. Any suggestions? Thank you. --kyler
