This is not the best solution in the world, since if you have more than a handful of sites, you get a combinatorial explosion. But, it will work. Perhaps someone who is bothered by this problem and has time will do some magic in VHM (or a new type of object) to stop such traversals. --jcc -- "Building Websites with Plone" http://plonebook.packtpub.com/ Enfold Systems, LLC http://www.enfoldsystems.com

Re: use Data.fs from mountpoint B to "populate" mountpoint A - how?

Please send all Zope related questions to a Zope related mailing list and not to me privately. Usually, I do not answer questions sent to me privately! I added "zope(a)zope.org".

Actually, the mount-point syntax is much more complex than the form you use above. Among others, it supports mount-point mount-path:storage-path "mount-path" describes how you reach the mount point in the mounting application and "storage-path" how you find the mounted object from the storage root. An example would be: mount-point /F1/F2/XXX:/S1/XXX Note that the last component in both paths *MUST* be identical (otherwise, Zope's url construction no longer works with URL traversal). Usually, the "storage-path" will look like "/XXX" (where "XXX" is some id (without '/')). If "storage-path" is not given, it defaults to "mount-path" (this explains why you do not see anything in your storage). To summarize: * always explicitely give a storage path * use a storage path of the form "/<id>" * then you can mount the storage at different places *BUT* you must never mount with a different id (the mount point must have the same id as that of the mounted object). -- Dieter

Cannot get zCommerce to work...
by news.hol.gr 27 Oct '05

27 Oct '05

Hello all, i am giving zCommerce a try and i have problem to get it to work with the sample database. I am using Plone 2.0.5 witch comes with zope 2.7.0 and Python 2.3.3 I tried to install the products (Session 0.3, zCommerce 0.2). The i create a "Session" from ZMI inside a folder under Plone. Then i create a "Z Gadfly Database Connection" inside "Session" using the sample database tha comes with zCommerce 0.2. Then i create a "zShop" into "Session" using the Z Gadfly Database Connection i created before and chosing to import the demo shop. The manual (INSTALL FILE) says : "In the manage interface, browse to the zShop, click on the Catalogs tab and, if you're using our sample gadfly database, add a new Catalog called sample. Otherwise, create a new catalog. Click on your newly created Catalog and start adding products and categories" The problem is i do not see any "Catalogs tab" and the only thing that works is testing the connection by giving "select * from productstorage" witch retrieves the table's lines and shows them ok. I tried the above by intsalling the products both in the "Plone 2\Data\Products" and the "Plone 2\Zope\lib\python\Products" paths and the sample Gadfly database both in "Plone 2\Data\var\gadfly" and the "Plone 2\Zope\var\gadfly" paths respeactively. As the manual says : "zCommerce *REQUIRES* Zope 2.2. If it works with Zope 2.1, then it's a fluke and we can't really help you if you have problems." Is there a possibility that it is not compatible with NEWER version of Zope-Plone? If so, have you tried any other product on this category (e-shop, cart...) that works with Plone 2.0.5-Zope 2.7.0-Python 2.3.3 and above? Thank you very much in advance.

database connections from external method
by Vangelis Mihalopoulos 27 Oct '05

27 Oct '05

Hi, I want an external method to access a mysql database on each call. For now, i open up a new connection on every call, but this probably won't scale much either on performance (new connection on each call is quite an overhead) or availability (the number of open connections is restricted). I am thinking of using a Z Database Connection (mysql) from within an external method, without using Z SQL Methods, but can't figure out how i can "safely" do it... It crossed my mind to take a peek to the Z SQL Method source, but i don't know if such an approach would be thread safe... Any thoughts? Thanks, Vangelis

From zpt -> to >zsql? > > > [cc-ing: zope(a)zope.org] well, yes in a way. ZSQL methods have to be called like other metods, but AFAIK, they cannot be traversed like, for instance, scripts. As I understand it, this is for security reasons (I myself would never allow a zsql to be exposed without some scripts in between, but that's just me...) Anyway, one way to do what you want is to do more in the zpt than may be advisable: exactly how to do it, I leave up to you, becasue there are several different ways of achieving this, but I give general directions. Also, there are probably other ways than what I describe below. You can make the form post to iself, and use calls inside the form to prepare the input to the zsql. lets say your zpt is called "entry_form" and looks something like this (pseudo zpt): <span tal:define="name request/form/name; account request/form/account; unused python: clients_add_sql(name=name, account=account);" tal:omit-tag="" /> <form action="entry_form"> <input type="text" name="name"> <input type="text" name="account"> <input type="submit"> </form> Not sure if this works, but that is the general idea. This was inspired from http://www.plope.com/Books/2_7Edition/AdvZPT.stx#2-9 section: "Form Processing" Good luck! /dario -- -- ------------------------------------------------------------------- Dario Lopez-Kästen, IT Systems & Services Chalmers University of Tech.

passing the parameters to zsql method
by Denis V. Gudtsov 27 Oct '05

27 Oct '05

Hello! I'm trying to pass the form parameters from page template to zsql method. A piece of code follows: <form action="clients_add_sql"> <input type="text" name="name"> <input type="text" name="account"> <input type="submit"> </form> clients_add_sql: insert into table(name,account) values (<dtml-sqlvar name type=string>, <dtml-sqlvar account type=string>); the problem is when i click the 'submit' button, the form "clients_add_sql Input Data Enter query parameters:" appears. Does someone know how i can pass the form parameters to zsql method directly? --
