Python base classes again (and now I'm really stuck)
by Itamar Shtull-Trauring 22 Nov '99

22 Nov '99

I want to create a Python base class that inherits from the ObjectManager and has the "Subobjects" tab in the ZClass management screen. Inheriting from OFS.ObjectManager.ObjectManager does not do this - I need to inherit from ZClasses.ObjectManager.ObjectManager. I still don't know how to have the Subobjects propertysheet thing work. I've tried the two ways I listed in my last email of doing this, but I can't get it to work. One way was: class MyObjectManager(ZClasses.ObjectManager.ObjectManager): " .... " class ZMyObjectManager: """Mix-in for Object Management """ _zclass_=myObjectManager propertysheets=ZClasses.ObjectManager.ZObjectManagerPropertySheets() manage_options=( {'label': 'Subobjects', 'action' :'propertysheets/subobjects/manage'}, ) and then register ZMyObjectManager as a base class in __init__.py. The other way was: class MyObjectManager(ZClasses.ObjectManager.ObjectManager): propertysheets=ZClasses.ObjectManager.ZObjectManagerPropertySheets() manage_options=( {'label': 'Subobjects', 'action' :'propertysheets/subobjects/manage'}, ) and register that as the base class. Neither of them work. -- Itamar S.T. itamars(a)ibm.net

Hi Everyone -- I'd greatly appreciate any help. Question by example: if I have a form: <FORM action=showme> <INPUT name=first_name value=Jim> <INPUT name=email value=jim(a)whereever.com> <INPUT name=first_name value=Bob> <INPUT name=email value=bob(a)whereever.com> <INPUT type=submit value=OK> which calls "showme" <dtml-in email> <dtml-var "_['sequence-item']"> </dtml-in> it returns jim(a)whereever.com bob(a)wherever.com but how would I return: Jim jim(a)whereever.com Bob bob(a)whereever.com Thanks! -- John

Re: [Zope-dev] Keyword Indexes in ZCatalogs

Hello, Thanks for this information. I tested Keyword indexes in a simple keyword search form for ZClass documents. It works beautifully. I'll summarize it in a mini-howto. Cheers.

Is _getOb() best way to grab a ref to a particular object?
by Andrew Wilcox 21 Nov '99

21 Nov '99

I need to grab a reference to a particular object in the ZODB from an external method, bypassing acquisition. Is this the right way to do it: def test(self, REQUEST=None): """doc string""" myobj = REQUEST.PARENTS[-1].aTopLevelFolder.anotherFolder._getOb('id_of_myobj') ...do stuff with myobj: myobj.title, myobj.index_html, myobj.property = 123 ...

Creating Python base class for ZClasses
by Itamar Shtull-Trauring 21 Nov '99

21 Nov '99

I want to create a Python base class that inherits from the ObjectManager ZClass, since I want to have it automatically add the "Subobjects" tab in the ZClass management screen. Inheriting from OFS.ObjectManager.ObjectManager does not do this - I need to inherit from ZClasses.ObjectManager.ObjectManager. Would the appropiate way to do this be: class MyObjectManager(ZClasses.ObjectManager.ObjectManager): " .... " class ZMyObjectManager: """Mix-in for Object Management """ _zclass_=myObjectManager propertysheets=ZClasses.ObjectManager.ZObjectManagerPropertySheets() manage_options=( {'label': 'Subobjects', 'action' :'propertysheets/subobjects/manage'}, ) and then register ZMyObjectManager as a base class in __init__.py? Or should I do: class MyObjectManager(ZClasses.ObjectManager.ObjectManager): propertysheets=ZClasses.ObjectManager.ZObjectManagerPropertySheets() manage_options=( {'label': 'Subobjects', 'action' :'propertysheets/subobjects/manage'}, ) and register that as the base class? -- Itamar S.T. itamars(a)ibm.net

draft how-to on local roles and the owner role.
by Anthony Baxter 21 Nov '99

21 Nov '99

I've just started a how-to on local roles and the owner role at http://www.zope.org/Members/anthony/owner_role/ The information is just collected from some posts by Brian Lloyd to the zope list, but hopefully will be easier to find as a how-to. Comments to me - I'll have another bash at it tomorrow, then add it to the catalog. Anthony

Yep - you should go to the security tab for the folder(s) that are accessible only to auth'd users, and for each of 'view', 'access contents' and whatever else you want to shutoff: uncheck the 'acquire permission settings' box make sure 'anonymous' doesn't have the box checked check the box for your new role Anthony

User authentication using UserDB
by Stephan Richter 21 Nov '99

21 Nov '99

hello everyone, I just learned how to use UserDB to have a login on my page. Okay, I got to the point where I can login and the AUTHENTICATED_USER is set to my new username. But now how can I use this login and the Zope security features to actually shut off sections of my site. Basically I want to make certain directories only available to the logged in user. Note: I also created a new role. All users that are authenticated and have this role can see a certain directory. Is it right that I have to use the "Security" tab? What do I have to do? regards, stephan -- Stephan Richter iXL - Software Designer and Engineer CBU - Physics, Computer Science and Chemistry Student
