*** MJ is now known as MJ|lunch13:24
dennis_the view is registered for a context, and the permission of the context is what is considered (both for wether the view is available to the current principal, and what information of the context it can access)13:36

*** MJ|lunch is now known as MJ13:45
junkafariandennis_: i am trying to edit the permissions on an object for a specific principal which should prevent them for viewing the object13:49
junkafarianhowever when i log in via FTP it does not reference the correct permissions13:50

dennis_junkafarian I don't have any immediate ideas .. sorry, do you set the permissions on the right object? (folder versus object etc)16:04
*** dobee has quit IRC16:04
junkafarianbasically the video objects are being displayed as folders16:04
*** cursor_ has quit IRC16:04
junkafarianso i can attribute/process various files to them16:05
junkafarianso i restricted the permissions on a video object16:05
junkafarian(eg to stop it being listed)16:05
junkafarianhowever it was still there16:05
*** marianom has joined #zope3-dev16:05
junkafariani cant seem to restrict the permissions on any object16:06
Crippssrichter: I've tried setting the template attribute by doing "self.template = ViewPageTemplateFile('templates/')" in the button handler, and I get "TypeError: __call__() takes at least 2 arguments (1 given)" as the final line of the traceback, and when I set template in the <page> directive, after the button is clicked, it just kicks me back to my form and prints out self.status ... I get the same thing with z3c.template/z3c.viewtempl16:06
dennis_showing the video as a folder, or showing its contents ?16:06
junkafarianthe video doesnt contain any objects16:07
dennis_cripps if you set self.template like that, you must do    self.template = BoundedPageTemplate( ViewPageTemplateFile(''), self )16:07
*** waa has quit IRC16:08
junkafarianhowever the code in synthesises files to display16:08
junkafarianso there is a metadata/data file ending in ".info"16:08
junkafarianhowever, you can also upload a video file which will then be processed by the logic16:09
*** greenman has joined #zope3-dev16:10
*** waa has joined #zope3-dev16:12
dennis_junkafarian the idea is quite cool, I will someday need to have something like that :) but I'm not sure what is causing the problems right now16:17
junkafariandennis_: if you're interested have a look at
*** lucielejard has joined #zope3-dev16:18
*** ferrafox_ has joined #zope3-dev16:19
junkafariandennis_: + thanks for looking ;)16:20
dennis_are your users hardcoded in the principals.zcml or in some kind of principal folder?16:20
junkafarianin a principal folder16:21
junkafarianonly the permissions/roles are hardcoded16:21
dennis_do you keep videos in the zodb ?   (getting a bit off-topic reading your architecture docs)16:22
junkafarianon the filesystem16:23
junkafarianwe need to provide a scalable framework16:23
dennis_ah yeah could have told that from your code :)16:23
Crippsdennis_: ahh. thank you. Is BoundedPageTemplate in the same package as ViewPageTemplateFile ?16:26
edgordonthe 'add' menu doesn't seem to do any sort of checking to respect item prconditions. is there a standard way to do this (ie, items are only shown in the add menu if they can actually be added)16:33
