ZCatalog and Search Results
by Aaron Payne 13 Jun '00

13 Jun '00

Hi all, I have a zcatalog. I use the methods generated by Z Search Interface to search the catalog. These methods will not recognize new additions to the catalog. After adding a coupon instance, the catalog search fails to find the new coupon or even the the old coupons. The add method of the zclass does have the statement: <dtml-call reindex_object>. The ZClass is subclassed catalogaware. There is a bug in Zope documented in the mailing lists. I found and tried the following code for my zclass add method: <HTML> <HEAD><TITLE>Add Coupon ZClass</TITLE></HEAD> <BODY BGCOLOR="#FFFFFF" LINK="#000099" VLINK="#555555"> <dtml-if DestinationURL> <dtml-call "RESPONSE.redirect( DestinationURL+'/manage_workspace')"> <dtml-else> <dtml-call "RESPONSE.redirect( URL2+'/manage_workspace')"> <dtml-with "CouponProductZClass.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-call "propertysheets.Basic.manage_changeProperties( REQUEST)"> <dtml-call reindex_object> </dtml-with> </dtml-if> </body></html> When I try to and an instance I get this error: Error Type: AttributeError Error Value: _u I am not sure how to restructure the method. I've been working on this for a while and I am stuck. Peacefully, Aaron

problem with 2.2.0b1
by Harald Ragger 13 Jun '00

13 Jun '00

I just tried the new 2.2.0b1, and most imported things from my 2.1.6 installation are running fine, including all sql-methods. But: when I choose one sql-method from the management interface or try to add a new one, i get the following error-message: "Warning: There are no SQL database connections. You need to add a Zope SQL database connection before you can use a Zope SQL Method. " Thats funny, because I know, that the DB connection is up and running. Any Idea? Harald

Re: [Zope] dtml-if confusion

I believe you need the following ( the following is psuedo code): an initial dtml method that processes your form, let call it dtmlForm and it has a variable prod_req which says how much of the product is requested. In dtmlForm you of course must call some dtml method which we call dtmlVerify. In dtmlVerify you need to check: do a dtml-let xyz= "queryProduct" ... do a dtml-if "xyz <= prod_req" then ok else error. I think that's it. let me know if this helps. -----Original Message----- From: Kenny Flegal <soulstompp(a)hotmail.com> To: zope(a)zope.org <zope(a)zope.org> Date: Tuesday, June 13, 2000 11:48 AM Subject: [Zope] dtml-if confusion >I have basically completed a management interface for one of our clients >using zope.

How do I do...
by Andre van der Vlies 13 Jun '00

13 Jun '00

Hi, I am at loss. I am struggling with Zope and just testing a lot of stuff. So I got this 'Folder' filled with images, SQLmethods, DTMLmethods etc. etc. I wanted to bring some order in this. So I made the Folders Gfx, Sql, SearchDatabase, Utility.... and moved the stuff mentioned above around... And ther my trouble starts. How do I reference from 'SearchDatabase' a method in 'Utility' (which uses statement from 'Sql'). Some stuff I've got working. Referencing the images as "Gfx.<name_of_image>" seems to help. Calling a SQLmethod as "Sql.<sql_method>()" works too. However, if I want to use a "Utility.<method>()" which uses something in "Sql" I am at loss.... Furthermore I have the feeling that this isn't the way it was ment to be... Is there a 'correct' way of doing this??? -- Andre van der Vlies <A.G.van.der.Vlies(a)ict.hva.nl> System Administrator Hogeschool van Amsterdam Stadhouderskade 55, Amsterdam tel : (+31) 20 5702 670 fax: (+31) 20 5702 510 xoip: (+31) 20 8771 304 http://www.ict.hva.nl/~andre Key fingerprint = 99 DC D6 01 96 C2 48 80 DC 9C D5 D2 34 F6 A6 5D -- Contrary to popular opinion, Unix is user friendly.

logout
by Erik Myllymaki 13 Jun '00

13 Jun '00

I saw this little bit posted in the mailinglist archives: <dtml-raise Unauthorized> </dtml-raise> I made a DTML method with just these two lines in it. Of course when I call it I get into a recursive *logout -> login and call this method again -> logout -> login and call this method again ...* loop. What is the cleanest way to avoid this? Thanks,

dtml-if confusion
by Kenny Flegal 13 Jun '00

13 Jun '00

I have basically completed a management interface for one of our clients using zope. I have your standard product and order management. If a customer orders something that is out of stock I need to create a back order. I add an order in a query called addorder, in this I need to set up an if statement to make sure their is enough product in stock. I have a seperate query called onhand, this selects a product and returns instock a field containing the number in stock of a product. I need to pull instock from this query and subtract quantity they entered in the form and find out if the result is greater than or equal to zero. I have the insert statement and everything else I just can't figure out how to call instock from the onhand query and quantity from REQUEST (I think it is still in request even though i am in a ZSQL method) and then test if the result is greater than or equal to 0. If anyone could help me with this it would be greatly appreciated. ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

saving files to zope
by josh on 13 Jun '00

Hi, I want to export images from a shockwave file and have them stored on my computer and accessable by zope. Can I just have the shockwave movie save files to say: www.myzopeserver.com/savefileshere where that folder has its permissions set such that anonymous can post a file there? or is it more complicated than that? thanks josh on.

The Find machinery (and therefore, ZCatalog) uses the method "objectItems" to locate the children of an object. If such a method does not exist or does not return the sequence of children, the catalog will not find them. Dieter

Secure storage of credit card info
by R. David Murray 13 Jun '00

13 Jun '00

OK, any of you out there who have thought about ecommerce, cryptography, and zope, I've got a design question for you. Actually, this question is independent of zope, but I need to solve it in a zope context. You have a ZCommerce site. You accept credit cards, and securely communicate with a CC processor to verify the transacton. Now, you want to save the CC# and other info in case something needs to be done with it later, and probably store the CC# so this customer doesn't have to type it in again later. Regardless of whether you are storing this info in a relational database or in the ZODB, how do you secure that information? Ideally I'd like it to be encrypted on disk. Now, storing it in a database probably makes it pretty hard to grep out even if a hacker manages to snarf the database file, but I'd like to encrypt it. But if I encrypt it, I have to have a decryption key somewhere. Where do I store the decryption key so that the cracker who snarfs the database file can't get it (just in memory somewhere?), and yet have the system be able to boot itself, including having the key, without human intervention? It seems to me like this is a Hard Problem, but I'm not up on the current cyrptography practice. So if there is a well known general solution, I'd love to hear about it. Otherwise, does anyone know what current Best Practice is? --RDM
