Creating products from Python scripts
by Carlos Alberto Micucci 09 Nov '01

09 Nov '01

Hi, I'm Argentino and my English is poor, sorry. I'm new in ZOPE, but I´m near to start a big project with it, a web application to query any remote database (or local) by SQL sentences with a user friendly interface to generate reports, graphs, ... to users with no knowledge about SQL sentences. My first problem is create instances objects of ZOPE from Python scripts, like: ZSQLMethods, ZODBCDA, folders, and so. I've probed with manage_addProduct (where Product is de name of product to create). Folders objects is OK, from manage (test) and visiting URL from browser. ZSQLMethods objects trought an error from URL and from manage (view): attribute error. By other way, I've probed with ZOQL product (Insert ...) but some products like "Z ODBC Database Connections" trought an error like: object is not callable. Could you help me, which is the correct way to handle this problem? I've read documentation like: ZOPE book, Zope Development guide, HOWTO, Tips and others, but this problem is not clearly documented. Other: which is the correct way to pass arguments (or parameters) to product ZOPE object (like ZOQL Methods, for example) from Python scripts? (ZOQL Methods object and Python scripts are in the same folder). Have you any example? I hope, you can help me. Sorry for my redaction... Thanks, for all. bye, Carlos. ===== Ing.

Re: [Zope] Caching on-the-fly resized photos (implemented)
by Robert Rottermann 09 Nov '01

09 Nov '01

Ron, I downloaded V1.22 and installed it and did run upgrade one a site with some 1000 photos. Everything worked fine. I found a small bug. In editSettingsForm.dtml you are using store unconditionally. I do have photos without store (dont know why) that do not like such a form. Now for a totally differnt matter. I need Photo translated into at least french and german. As you know, Zope does not really hinder translation but that is about all the help one gets in that realm. I would suggest to add a primitive translation support to Photo. What I have in mind is that every source file has a from translate import translate added. translate in its simplest incarnation does nothing but return its input. In Photo for every string meant to be seen in the user interface one would call translate with that string. Somebody who wants to have Photo translated would provide an appropriate translate function. I would happyly do this adaptation of your code. However we should find a way how to have it merged into your code stream. Robert

by zope＠virtosi.com 09 Nov '01

09 Nov '01

hello there: i am having upload issues. i would like to upload a file, some text, and meta-data (all form fields...) and then move (and rename) that file to a specific directory based on the meta-data. so,,, i am sending the requests directly to an External method. ### DTML #### <input type=my_external_method action=post enctype='multipart/form-data Title: <input type=text name=file_nae size=10> File: <input type=file name=myfile> <input type=submit> </form> the LocalFS products manage_upload seems to do what i want, but i don't know how to access it from an external method (and i would need to for other reasons). does Zope hand off the request directly to the external method?? could i use the cgiupload.py module ?? thanks for your help, --james jackson, aspiring zope-buster...

object references in python (script)
by HNBeck＠t-online.de 09 Nov '01

09 Nov '01

Hi all, I've no idea where may be an error at the folling code: ---- # create a unique id id= str(linkname) + str( len(context.objectIds())) # add new instance of DokuTypeID (hint from mailing list) context.REQUEST.set('id', id) my_context= context.manage_addProduct['DokuItem'] my_context.DokuTypeID_add(my_context,context.REQUEST, NoRedir=1) # add a guest_name string property (variant of the guestbook example in Zope Book) context.REQUEST.set('keyword',id) doc=getattr(context, id) doc.manage_changeProperties(context.REQUEST) ---- DokuItem is a own product, containing the class DokuTypeID, which has the property 'keyword'. Assume the code has to create an instance in folder "anything". Instance is created - good. But not the property of the new DokuTypeID instance is set, the property of the folder "anything" (which also has the property "keyword") is overwritten. ??????? So it seems, the variable doc points to the folder object, not to the new instance in it. Why ???? Thanks for help! Greetings Hans ----------------------------------- Dipl.-Ing. Hans N.

TypeError, Unsliceable object from standard product add
by complaw＠hal-pc.org 09 Nov '01

09 Nov '01

The attached file contains the error message that occurred when I tried to add an object. The object itself is defined in a custom product. However, that ZClass itself was made with the standard tools in Zope 2-3-1 (an oldie, but a goodie). I caughed up when I was trying to create the object. The add DTML is below (unadultered after it was created by the wizard): <HTML> <HEAD><TITLE>Add sw_patent_property</TITLE></HEAD> <BODY BGCOLOR="#FFFFFF" LINK="#000099" VLINK="#555555"> <dtml-comment> We add the new object by calling the class in a with tag. Not only does this get the thing added, it adds the new thing's attributes to the DTML name space, so we can call methods to initialize the object. </dtml-comment> <dtml-with "sw_patent_property.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-comment> You can add code that modifies the new instance here. For example, if you have a property sheet that you want to update from form values, you can call it here: <dtml-call "propertysheets.Basic.manage_editProperties( REQUEST)"> </dtml-comment> </dtml-with> <dtml-comment> Now we need to return something. We do this via a redirect so that the URL is correct. Unfortunately, the way we do this depends on whether we live in a product or in a class. If we live in a product, we need to use DestinationURL to decide where to go. If we live in a class, DestinationURL won't be available, so we use URL2. </dtml-comment> <dtml-if DestinationURL> <dtml-call "RESPONSE.redirect( DestinationURL+'/manage_workspace')"> <dtml-else> <dtml-call "RESPONSE.redirect( URL2+'/manage_workspace')"> </dtml-if> </body></html> Any idea what the problem could be? I'm surprised to get this error as the only thing that I did was create a ZClass and then try to instantiate an object. Thanks in advance for any hints or advice. Ron

RE: [Zope] Connecting to MS SQL Server
by sean.upton＠uniontrib.com 09 Nov '01

09 Nov '01

I think I suggested something on the list before that might be a good idea, if someone would write a DA for it, but there is some XML-over-HTTP-based protocol using IIS that SQL server 2000 works with as well as TDS. I can't imagine it is as fast (since there is XML-parsing overhead on both ends), but I saw that someone created a library with a Python DB 2.0 compliant interface to access this, based upon the MySQLdb code, adapted for use with SQL Server 2000... I'd write a DA for this myself, Since I don't use M$ $QL, perhaps this is best left to someone who acutally has and uses the SQL Server 2000 software... http://pyxsqmll.sourceforge.net/ Sean -----Original Message----- From: Tille, Andreas [mailto:TilleA@rki.de] Sent: Friday, November 09, 2001 2:15 AM Cc: Zope user list Subject: [Zope] Connecting to MS SQL Server Hello, is it possible to connect to a MS SQL Server from Zope running on a Linux box?

RE: [Zope] permissions broken?
by Courrier 09 Nov '01

09 Nov '01

hello, I've tried what you said when "standard_html_header" and "standard_html_footer" are owned by "dev", it work with "Access contents information" permission set for manager role. I think, it's because of aquisition of DTML Method owned by root. Am i right ? I new to Zope, and I want to learn a lot about security. If you have exercices like this one, i appreciate it. (i need also grammar correction, isn't it ;) Xavier Today I tried on my Zope Zope 2.3.2 (source release, python 1.5.2, linux2) what I did a hundred times succesfully before: 1. created a folder "production" 2. set not to acquire the "View" permission for this folder 3. created a role "developer" 4. created a user "dev" with role developer 5. changed security settings so that developers can "View" 6. created two dtml-methods "standard_html_header" and "standad_html_footer" inside the new folder 7. logged in as dev and got the error message: Unauthorized You are not authorized to access standard_html_header Strange enough, this only occurs with standard_html_header and standard_html_footer. I also created a dtml-method called index_html and could see it.
