Hola Paula, lamentablemente no tengo mucha experiencia con Zope 2.7, pues en estos momentos tengo instalado el 2.6.2b4. Pero quizás debas modificar el "zope.conf" que viene en el directorio "zope-instance". Por cierto, en esta lista el lenguaje oficial es el inglés, para mensajes en español debes postear en: http://listas.aditel.org/listinfo/zope-es Saludos, Josef

python variables in javascript
by Exteam 29 Jul '03

29 Jul '03

Hi all, I have some variables in python (getting from DB), now what is the best way to access these variables in javascript? For example, i want to populate person name , city & street which are separate textboxes. If i change the person name, the city & street should automatically change by using javascript onChange event. Are there any examples onthe web in this approach?

Estamos realizando un trabajo final referido a Zope. Por tal motivo, bajamos el ejecutable : 'Zope-2_7_0-b1-win32.exe' de la página oficial de Zope. Lo corrimos en una PC con sistema operativo Windows 98. Nuestra pregunta es: - Cómo debemos hacer para correr Zope pues cada vez que cliqueamos el run nos abre una consola de DOS con el mensaje : 'Finalizado - RUNZOPE' . Alcanza con el instalador qué bajamos o tenemos que instalar algo previamente? Hay que setear o configurar algo para hacerlos arrancar? ------------ Internet GRATIS es Yahoo!

Why doesn't this work?
by Terry Hancock 29 Jul '03

29 Jul '03

This is a simple project example. I'm trying to wrap an object generated on the fly and publish methods from it. However, as I'm doing it, I get an HTTP authentication challenge, and it does not recognize any usernames, including the superuser, so I always have to click "cancel" which gives me a "you are not allowed to access index_html in this context" in this case. The main module is included below, and I've put a tar file of the product here: http://manage.narya.net/Anansi/Download/PBTest.030728.tgz To test it: * Add a "My Container" object ("folderish"). * Inside the "My Container" object, create a python script called "test_html", with the following contents: """ return context.get_obj("Green").index_html """ * Access the URL of the test_html script. What should happen is that the server should return text saying "Test version of index_html for Green object." But what I actually get is a challenge popup, which I can't satisfy with any valid usernames on the server, and thus I get the message: """ Error Type: Unauthorized Error Value: You are not allowed to access index_html in this context """ Obviously, there's something incomplete about the PB_Object instance, but I can't figure out what it might be. Source of PBTest.py: ---snip------------------------------------------ # Test returning PB transitory object from a folder-like object. # This is a technique I want to use in Narya, but it's running into # permissions problems.

python script to upload file with dynamically generated filename
by David Siedband 28 Jul '03

28 Jul '03

I'm working on a script to upload a file to a file repository (zope folder) and generate a custom file name. My intention is to use a LocalFS object (instead of the Zope folder) once this bit is sorted. My goal is to rename the file based on the filename and extension variables that I'm passing to the script. The part I'm stuck on is the syntax of this part: manage_addFile(id='%s%s % (filename, extension)', title='', file=file) In this example I'd like to set the id to 'thefile.jpg' TIA, David +++++++++++++ [ script ] +++++++++++++++ #parameters file, filename='thefile', extension='.jpg' """ Uploads a file to the repository with a crafted id. """ from Products.PythonScripts.standard import url_quote # crafts the filename and creates the file container.Files.manage_addProduct['OFSP'].manage_addFile(id='%s%s % (filename, extension)', title='', file=file) # creates the success message message="The file '%s' has been added to the repository." % file.filename # redirects to the file repository interface page return context.REQUEST.RESPONSE.redirect("%s/repository_html?message=%s" % (container.absolute_url(), url_quote(message)))

Could you please explain with details how to create a folder owned by a group? Is it a folder or a CMF Topic Object? I made a test with a folder but I can't see anything in my Plone interface... I don't understand what you mean by " create a new Type as a > copy of the Folder type and change its actions". Could you give me an exemple? Thanks. Patrick Gelin

Assumption on use of .render() in rendering formulator field in the actual HTML

>It is my assumption that when we use .render() on the formulator field, it >names the field from formulator as field_fieldname, in the actual HTML. >There is no other alternative to render to get the fieldname as >field_fieldname. Is my assumption correct. Since .render() already gives you the fieldname as field_fieldname, why would you need an alternative to achieve the same purpose? > alternative to render to get the fieldname as field_fieldname. ------------------------------------------------------------- I'm going to make an assumption. Here's what I think you are asking- First, I'll quote faassen from the formulator page http://www.zope.org/Members/faassen/Formulator "Don't ever use field_<fieldname>; anything prefixed with field_ in REQUEST is a Formulator implementation detail. Instead, don't forget to validate the form" From what I've been able to deduce about formulator... Your ZPT or DTML renders the form using formulator, the user's responses are put into temporary variables named field_fieldname. You then use formulator's VALIDATE functions, they process the field_fieldname variables and pass the values that are valid into appropriately named fieldnames (without the field_ prefix). I assume this is what you are unclear about. Of course, I've only begun messing with formulator I could be completely wrong, but this is how I've been using the formulator product. --YMMV ------------------------------------------------------------- If you do not get appropriate assistance, you should probably revise your question and post it to the formulator-specific mailing list http://lists.sourceforge.net/lists/listinfo/formulator-general

Assumption on use of .render() in rendering formulator field in the actual HTML
by Exteam 28 Jul '03

28 Jul '03

Hi.. It is my assumption that when we use .render() on the formulator field, it names the field from formulator as field_fieldname, in the actual HTML. There is no other alternative to render to get the fieldname as field_fieldname. Is my assumption correct. Regards exteam SMS using the Yahoo! Messenger;Download latest version.

exUserFolder + MySQL + Python syntax problem
by David Washburn 28 Jul '03

28 Jul '03

I am having trouble accessing the API functions in exUserFolder. I am using exUserFolder because I need to merge user data and properties with a MySQL database table. I have taken the approach of making one "account" table that has many properties of a user (first_name, last_name, title, office_telephone....). I did this because some of this data will be maintained by an application outside of ZOPE and the single record approach works best for that configuration. What I want to do is, at login time, load various fields from that "account" table into temporary properties that I can access throughout the site. To do this, I built a LoadProperties Python script that looks like this: ================================================= MyUsername = context.REQUEST.AUTHENTICATED_USER context.REQUEST.AUTHENTICATED_USER.flushTempProperties for user in container.ListUsers(username=MyUsername): context.REQUEST.AUTHENTICATED_USER.setTempProperty('account_id' , user.account_id ) context.REQUEST.AUTHENTICATED_USER.setTempProperty('username' , user.username ) context.REQUEST.AUTHENTICATED_USER.setTempProperty('user_type' , user.user_type ) return =================================================== and it calls a ZSQL Method called "ListUsers" to retrieve the current user. I've tested that and it works. What I can't seem to get working is the ".flushTempProperties" and ".setTempProperty" calls. I call ".flushTempProperties" because I want to clear all temporary properties before I load new values from the "account" table. The syntax <dtml-var "AUTHENTICATED_USER.getProperty('full_name', '')> worked in a DTML document to retrieve a properties which I placed into the "account" table where user info is stored. Can someone suggest the correct syntax to access the ".flushTempProperties" and ".setTempProperty" functions inside my Python Module? Thank you for you time, David ======================================= David T. Washburn DWashburn(a)AmInfo.com Amherst, MA USA 413 256-3103

Running Zope 2.7 as daemon
by Alec Munro 28 Jul '03

28 Jul '03

I'm still a relative linux newbie, and while I was able to install and successfully run 2.7, I have very little clues about how to run it as a daemon. I don't even know if that's exactly the word I'm looking for. I don't want to have to start it manually. Right not I start it with: runzope -X port-base=1000 This works, but it takes over my SSH shell to keep it up. I did some searching, but most of the information I found refers to earlier versions, using z2.py. Thanks, Alec Munro
