Re: [Zope] Displaying contents of folder

You need to use objectValues() for this. Note that you can look for special objects with this notation. objectValues(['Folder','File', 'DTML Method']) For example this would list all objects in the subfolder test.  <dtml-in "test.objectValues()"> <dtml-with sequence-item> <dtml-var id><BR> </dtml-with> </dtml-in>  HTH __Janko

Displaying contents of folder
by Itamar Shtull-Trauring 10 Oct '99

10 Oct '99

I have a folder called test which contains some DTML methods. I want index_html, which resides at the same level as test, to execute all the methods inside test:  <dtml-in test> <dtml-var sequence-item> </dtml-in>  This does not work. So how do I do it? -- Itamar - itamars(a)ibm.net ---------------------------o----------------------------------------------o Perl/Gimp Greeting Cards | Trust? Ha!

Rename BUG
by Li Dongfeng 10 Oct '99

10 Oct '99

I don't know if this is a bug. Upload two GIF files, name them as gif1 and gif2. Put a reference <dtml-var gif1> somewhere. The picture shows correctly. Now delete gif1, rename gif2 to gif1, but the <dtml-var gif1> reference still display the old deleted gif1, not the new gif1(originally gif2).

Ordered Folders - take 2
by Itamar Shtull-Trauring 10 Oct '99

10 Oct '99

I decided to add the ability of making an object first, as suggested by Janko and implemented in ZClass views, to the standard Folder class, since this should be useful for all folders, so why not? SO if I'm succesful and DC says it doesn't break anything all our Folders will have this capability. I altered the main.dtml file in lib/python/OFS/ by adding these lines:  <INPUT TYPE="SUBMIT" NAME="manage_first:method" VALUE="First">  And altered the Folder class by adding a manage_first method which I ripped from lib/python/ZClasses/Basic.py (see below for the result). Now I have two problems: a. Will this method actually work? I don't know enough Python, so I'm guessing here. b. How do I connect it to the web interface so that calling manage_first as a method will actually execute this function? Here's the new Folder class: class Folder(ObjectManager, PropertyManager, RoleManager, Collection, SimpleItem.Item, FindSupport): """ The basic container object in Principia. Folders can hold almost all other Principia objects. """ meta_type='Folder' _properties=({'id':'title', 'type': 'string'},) manage_options=( {'label':'Contents', 'action':'manage_main'}, {'label':'View', 'action':'index_html'}, {'label':'Properties', 'action':'manage_propertiesForm'}, {'label':'Import/Export', 'action':'manage_importExportForm'}, {'label':'Security', 'action':'manage_access'}, {'label':'Undo', 'action':'manage_UndoForm'}, {'label':'Find', 'action':'manage_findFrame', 'target':'manage_main'}, ) __ac_permissions__=(('Rearrange objects', ('manage_first',)),) def manage_first(self, selected=[], REQUEST=None): """Make some objects first""" objects=self._objects if not selected: message="No objects were selected to be made first." elif len(selected)==len(objects): message="Making all objects first has no effect." else: objects=self._objects objects=tuple( filter(lambda object, selected=selected: object in selected, objects) + filter(lambda object, selected=selected: object not in selected, objects) ) self.setClassAttr('_objects', objects) message="Objects were rearranged as requested." if REQUEST is not None: return self.manage( self, REQUEST, manage_tabs_message=message) -- Itamar - itamars(a)ibm.net ---------------------------o----------------------------------------------o Perl/Gimp Greeting Cards | Trust?

Over 200 Apache processes? That's alot. That's like millions of hits per day capacity if your hardware can handle it.

Define permissions
by Oscar Picasso 10 Oct '99

10 Oct '99

Let me know if I have a well understanding of the mapping in the "define permissions" tab. As I understand it if for and object X I map "permission A" to "permission B" the actual result is that a user must have both the permission A and permission B in order to access the object X. (Supposing that all other permissions are disabled). I've made several test in order to try to understand. So let me know if missed something.
