populating form values from a sql method
by Erik Myllymaki 26 Jul '02

26 Jul '02

A users starts with a blank form. She fills in some field values, slects some values form pull-downs. Submits the form which adds a new record into a database. Later, the user wants to update that infomation (or input a NEW record but use that info as a template). What is the cleanest way to pull up that form with the fields already containing the data from that database record? Is there a product that is close to this? Formulator? TIA

by Erik Myllymaki 26 Jul '02

26 Jul '02

I am currently using Zope2.3.2 on windows with python1.5.2. I need to use some functionality of python 2.1.1 which is also installed on the same machine. What is the easiest way to use the newer python with Zope? Changing the start script to use python2.exe instead of python.exe does not work. TIA

return structured result from Python scripts for page templates
by Gabor Nagypal 26 Jul '02

26 Jul '02

Hi, I would like to return a structured result (an "object") from a Python script to use it conveniently in a page template. E.g. I would like to have a get_person Python script which gives back a person with a name and an address. Then I could use a page template like: Name: John, lives at London What I tried, but did not work: 1. Create an empty object in the Python script, set some attribute, give back the result class Person: pass p = Person() p.name = "Mike" ... return p Result: Error Type: TypeError Error Value: attribute-less object (assign or del) 2. Create an object with functions class Person: def name(self): return "Mike" ... result: Resource not found Sorry, the requested resource does not exist. Check the URL and try again. Resource: ?.Person instance at 0157E384 3. Give back a dictionary return {'name':'Mike', 'address':'Paris'} the script now works, but I cannot access the values from the page template with the person/name notation. Any ideas how to achieve this functionality in ZOPE? I think it is so basic, that surely exists a way to do this. Gabor

concurrent logins and Zope
by Carlo Giomini 26 Jul '02

26 Jul '02

Hi everybody, I'd like to know if Zope can keep track of concurrent logins of the same user and treat them independently. Let's say user 'foo' connects to a portal and has many tasks to do (at the same time). He keeps an open browser window for each of them, logging in from each window (from now on I will call 'session' the whole sequence of actions issued from the same browser window, starting from login up to logout): what I'm thinking of is having the possibility to 'isolate' one login from another (of the same user at the same time) and keep track of each of these 'sessions' independently from one another: does Zope support this kind of task some way? I mean does it have internal structures, APIs, functions etc to do this or do I have to code the whole mechanism from scratch? It's worth noting that the point is not only telling one browser window from another (the BrowserIdManager fits well here), but also (mostly) keeping track of every 'session' (group of actions issued from the same browser by the same user) in parallel with every other. Of course the opposite situation could come handy as well: treating all the requests (issued by the same user) as an unique 'session', without regard of the browser window these were issued from. Any help will be appreciated (also references to source code). Thanks in advance, cheers, Carlo. P.S. With 'keeping track of a session' I mean keeping track of the status of the user related to that session, in some data structure like a table, dictionary, etc.

Keeping my promises - writing tutorials for Zope
by Heimo Laukkanen 26 Jul '02

26 Jul '02

During Europython 2002's BOF-sessions I promised to contribute to the community by writing tutorials for how to get into Zope for beginners. The need for these tutorials is clear, since we are teachingh Zope in our company, Fountain Park, and at the same other people have the same need too. Besides the Zope Book and other published books, there has been nothing to support users that are beginning their journey on Zope. There has been several howto's and guides for different things, but many are outdated or have only about one subject where as these tutorials are intended to be a series of information that will give a more complete view for the beginner user. Meaning these tutorials will be a series that have a common story that ties them together. These tutorials will not invent the wheel again, but create a clear path that people can follow and start their journey. My wish is that these tutorials will help more people to start use Zope in a good way and possible help Zope to land better into corporate world, when more users have knowledge and trust into this system. This is the beginning of my small contribution to the community. Hope this helps and someone else will also want to contribute. What I would like to hear from everyone else is, what things should be covered and how, to which other resources and how-to's I should link to and -- the most important part -- ' Hey nice idea, I could write about this thing' or 'yes, I commented to the wiki just a couple of minutes ago'. Frontpage for the project is found at: http://www.zope.org/Members/huima/tutorials/FrontPage And the first tutorial being written: http://www.zope.org/Members/huima/tutorials/IntroductionTutorial Please contribute and help to generate a new generation of Zope users! -huima

RE: [Zope] Page Template --> tal:repeat
by "Echeverria Rabi, Cristián" 26 Jul '02

26 Jul '02

Thanks for your help. Thanks to yours suggestions I solved my current problem. I've something like this: 1. A main page template that get the values and call a Python Script 2. A Python Script that query a database (calling another script). Then I have the result of the query in a variable. Then my script call another page template to do the rendering of the result. 3. A page template to render the results of the query (so I need to pass the variable with the result of the query). All yours suggestion worked, but I needed to include a line in my script before calling the final page template: contest.REQUEST.set('value',query_result) ... and then everything worked. I'm not sure this is the right way to do it, I'm just starting with zope, Any other comments?
