migrating a site to Zope
by Joachim Schmitz 20 Aug '99

20 Aug '99

Hello, I want to migrate an existing site to Zope. It's basically a portalsite for a city. A lot of the content is now in mysql-tables, of course it would be simple to include those also in the new site. But then I could not use ZCatalog on those, I assume. So what's the best way to import data from sqltables into a ZODB ? Perhaps sql-table -> xml -> ZODB ?

Authorization error with for missing values ??
by Brian Hooper 20 Aug '99

20 Aug '99

Hi! I've been trying to use DateTime values with ZSybaseDA, and have come across the following strange behavior: I'm doing a query to my database to get out data which includes a datetime field which can in some cases be NULL. (The field name is 'birthdate'; let's call the table, for the example, 'User'). I have a Z SQL Method selectUsers which does something like: select * from User which is referenced from a DTML Document like this: <dtml-in selectUsers> <dtml-var birthdate> </dtml-in> This works fine if none of the birthdates are NULL; however if birthdate is NULL, then I get an authorization dialog, even though I am already logged into Zope as a Manager in the top-level acl_users folder. The only way to get past the authentication dialog is to log in as the Zope superuser. What's going on here? I traced code to RDB.py, where it looks like Missing.MV should be substituted for any values which don't come back in the query results for a given field. The test() method of the selectUsers Z SQL Method handles things OK, but I don't seem to have permission to look at Missing.MV in a regular document... --Brian

Using Zope / Newbie Question
by Jörg Herbst 20 Aug '99

20 Aug '99

Hi, I'm looking for a Application Server to develope a eCommerce Product, I've heard quite a lot about Zope and read part the documentation; but before starting the development of a whole shop, I've still got a few questions: Can zope handle frames ? Can I display dynamical content in different frames, e.g. a product list in one frame and a product description in another ? Can zope handle different session of anonymous webuser (without username and password) ? I would be glad, if someone with more experience could help me. Greetings Joerg Herbst

DTML Documents vs. Methods--Again? Yikes!
by Tim Wilson 20 Aug '99

20 Aug '99

Greetings: I've been trying to figure out the difference between DTML Documents and DTML Methods. I'm reading the available docs, but true enlightenment still eludes me. :-) What are the tradeoffs in using these two seemingly similar objects? For example (and please feel free to expound on this), why is standard_html_header a DTML method and index_html is a DTML Document? Are there ZODB performance issues? Wishing there was Zope Zen pill available over the counter... -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.

Migrating between versions
by Tim Wilson 20 Aug '99

20 Aug '99

Good evenin' What is the proper procedure for migrating all of your Zope work to a new version of Zope. I've been busy working on 2.0b4, and I'd like to move to 2.0b5. How can I maintain all of my work? -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.

Re: [Zope] Giving up in frustration
by Antony Tersol 20 Aug '99

20 Aug '99

I too am new to Zope. It looks great, so I have jumped in and most all is going ok. Similarly to Pierre, I see an application I would like to create. I also am in the midst of trying to replicate the jobboard example. The example seems straightforward enough, but for someone just starting to work with Zope, it is not clear what one is to do with each of the files. I created a folder called Jobs, and made it's index_html file look like job_board.dtml, and created dtml files in that directory for job_listing.dtml and job_add.dtml. I then tried to add an ExternalMethod for add_listing, but it can't find it in JobBoard.py. When I call up Jobs in my browser "http://localhost:8080/Jobs", I get the jobboard as shown, but as shown in ObjectPublishingIntro, it should be called as "http://localhost:8080/scripts/jobboard.py" It functions as it should, moving to Jobs/job_add.dtml but again my urls are a little bit different. So I seem to be confused. The question: Where do each of the files go, and what do I have to do inside the Zope manage screens to get this to work? Second question: in the helpSys, under external method, it says to put it in the Extensions subdirectory, then in the next paragraph says that it is not <i>currently</i> possible to use Python modules that are in the Extensions directory. !? What exactly does this mean? Thanks for any help. Regards, Antony Tersol
