Any method called directly through the web (e.g. like this one, which I assume is through an HTTP POST) will be bounded in a transaction.

SQL-Output
by Andre Schubert 06 Jul '00

06 Jul '00

Hi, i have a little problem on outputting data from an SQL-Query. The Problem is, that the user should select his own Fieldnames he want to show for output. The input form sends a request to the output form, with a query-string and some other stuff and a key named ausgabe. The key ausgabe is a sequence with all Fielnames the user clicked. Now in the outputform i have a sequence looking for the search-query. If sequence starts it prints a table-head with all selected field-names out of the second sequence ausgabe. The problem is: my table in the relational database has a column named 'Name'. If i write in the sequence at bottom <dtml-var Name> then the result is the the value of Namne is printed. But if i write <dtml-var sequence-item> and the current item is Name then Name is printed out and not the Value of Name from the DB. Could anybody help me. as P.S.: sorry for my bad english <dtml-in Suche size=10 start=query_start> <dtml-if sequence-start> <table width="560" border="1" bgcolor="#eeeeff"> <tr bgcolor="#ccccff"> <th width="30%">Name</th> <dtml-in "REQUEST.ausgabe"> <th><dtml-var sequence-item> </th> </dtml-in> </tr> </dtml-if sequence-start> <tr> <td class="feld"><a href="homepage?Firmennr=<dtml-var Firmennr>&SUBMIT=Query Start"><dtml-var Name null=""></a> </td> <dtml-in "REQUEST.ausgabe"> <td class="feld"><dtml-var sequence-item null=""> </td> </dtml-in> </tr> <dtml-if sequence-end> </table> </dtml-if sequence-end> <p> </dtml-in>

Product Data Storage
by Andy Dawkins 06 Jul '00

06 Jul '00

I have an interesting issue which I don't think has been raised. But instead of solving the issue myself I thought I would share it with you guys/gals and see what you think. I am currently working on a Zope MailIn product, which allows you to send emails directly in to Zope. Version 0.1 can be found at: http://www.zope.org/Members/NIP/ZMailIn In version 0.2 I plan to have a ZMailIn python product which will handle the Zope side of things and behave a bit like a client. For example you could add a ZMailIn product instance in to Zope and configure it to receive all emails for bob(a)bobscompany.com and provide a method to execute upon mail arrival. This is great and you could have n ZMailIn product instances throughout your Zope site and in any position. When email arrives I need to find all the ZMailIn instances within the ZODB and hand the email to the correct one. I have decided AGAINST searching the ZODB for instances of ZMailIn because that is just too scary, hideously inefficient and I don't want to go there. Instead I thought of keeping an up-to-date list of where all the current instances where held. My original idea was to get the ZMailIn product to write a file in to the /lib/python/Products/ZMailIn directory, which shouldn't cause any problems that I can see. However, It had occurred to me that with the current growth of Zope it was going to become more popular that separate Zope instances of the same product may need to share some data. So my question is this: What are peoples opinions on storing shared product data? Where should it be placed? Should this ability be added to Zope as a standard? Thanks in advance. -Andy Dawkins (New Information Paradigms Ltd)

zpatterns-0.4: creating an item in "virtual mode"
by Jephte CLAIN 06 Jul '00

Hello, I use virtual attribute access to provide access to my SQL database. However, I want to use the Rack.newItem facility to create new records in the database. But it fails because in virtual mode, an item always exists.

ZClass inheriting from ObjectManager and DataSkin?
by Itamar Shtull-Trauring 06 Jul '00

06 Jul '00

Are there (or better yet, what are) any potential problems here? My gut feeling was that it wouldn't work, but you can at the very least add objects in instances of the ZClass - deleting and renaming don't work though. -- Itamar S.T. itamar(a)maxnm.com Fingerprint = D365 7BE8 B81E 2B18 6534 025E D0E7 92DB E441 411C

Yesterdays CVS: I can add broken products! :/
by Bill Anderson 05 Jul '00

05 Jul '00

OK, I am working on a CVS dump from yesterday of Zope2. I am upgrading from 2.1.6. I did so by making new folder, copying products that I actually used over, and building Zope, then bringing over the Data.fs. Oh, and ZEO is there too (Damn that thing is cool!). And now I have a very weird problem... I have a couple of ZProducts that are o _not_ listed as broken in Control_Panel/Products o Instances of them appear as "This object from the unknown Product is broken!" Here is the kicker: I can add new instances of them, and they too magically appear as broken, with no complaints about creating them! Also, I can't seem to pack the database. it claims it has already been packed to a later date. This db hasn't been packed in at least a month. ISTR something about the last one, so I'll be hunting the list archives, but if someone has a moment, and the answer, don't be afraid to shoot it my way.
