File Upload via form (with other form variable) and storing it in a database
by Edward Muller 03 Mar '03

03 Mar '03

How would I go about uploading a file via a form and store it in a postgres database using zope/zpt. I've never do this. I've used zope/zpt/zsql when dealing with forms before but never with a input type of "file". Any help or guidance would be appreciated.

security changes from 2.5 -> 2.6?
by Rob Miller 03 Mar '03

03 Mar '03

hi there, i'm trying to migrate a plone project from zope 2.5.1 to zope 2.6.1. the app relies heavily on database driven local roles information, for which we're using zpatterns and loginmanager. so we've created these custom plone folders called 'teamfolders'. these folders are dataskins, and they override get_local_roles() and get_local_roles_for_userid(), returning the appropriate responses based on the team membership information that is in the database. similarly, in our user class, we've overridden getRolesInContext(). in zope 2.5.1 this all works beautifully. zope recognized the local roles and allows access accordingly. even the 'local_roles' link on the security tab still works, although it doesn't allow you to delete the local roles that originate from the database. when i import my product into 2.6.1, however, things don't work as smoothly. everything looks like it should work... the local roles page still displays the right information. a test page that i've written consistently displays the expected results for here.get_local_roles() and here.get_local_roles_for_userid(), as well as user.getRolesInContext(). but zope doesn't allow the access based on this information. that is, even when 'teammember' is showing up on the user's local roles list, zope isn't allowing the user to perform actions that should be allowed to 'teammember'. has something changed within zope's security implementation? is there a new method that needs to be overridden that i don't know about? does anyone have any other ideas why this might be happening? i've searched on the zope.org site and the mailing lists to no avail... any info anyone can provide would be greatly appreciated! thanks! -r

objects invisible
by Danny Nielsen 03 Mar '03

03 Mar '03

Hi there. First I have to say that Im very glad that this group exists. Now the problem: Im a zope newbie and have startet making a product solely through Python (leaving the management interface behind!). Inside my product object I want to make a folder containing images. My problem is that when I create folders and images through Python it aint visible in the management interface. How to I make them visible? Secund, can someone explain to me what implicit objects are available so Im able to communicate with Zope (I have had a hard time trying to figure out howto communicate with Zope through a Python product - the docs API aint well documented) regards Danny -- Using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/

Storing a password in a python product
by Peter Bengtsson 03 Mar '03

03 Mar '03

What are the security implications of storing a password in a python product as persistent data? I was thinking of something like this: class MyProduct: def __init__(self, hostname, username, password): self.hostname = hostname self.username = username self.password = password But I will also need to be able to use the password in anonymous actions; otherwise I could ask for the password (in some suitable way) each time it's needed. Basically, how do I keep good security with sensitive persistent data in a python product? Peter

Add new property to a class
by Luis Machado 03 Mar '03

03 Mar '03

Having defined a class using python like this one: from OFS import ObjectManager, SimpleItem class Plant(ObjectManager.ObjectManager, SimpleItem.SimpleItem): """A plant""" def __init__(self, name, responsible): "Inits the product with default values" self.name = name self.responsible = responsible self.areas = {} you create a few instances, and later you want to add more properties to the same class, for example: def __init__(self, name, responsible, address): "Inits the product with default values" self.name = name self.responsible = responsible self.areas = {} self.address = address Is there a way to programatically modify the existing instances and add this new property to them. Any help will be appreciated. Luis

Really stupid acl_users mistake
by Marc Stein 02 Mar '03

02 Mar '03

I am quite new to Zope and have done something VERY stupid. I created an acl_users folder within an existing folder and added myself as a user. I did not however select either Manager or Owner and now cannot access the folder. Is there a way that I can either programmatically delete the user folder or change the permissions to allow access to this folder? I am the only current user on the system. Many thanks in advance.
