Using Zope, I have managed to put together a nice site for friends to =
create folders, pages and upload images, etc. But there are some =
fundamentals that are eluding me.
I am able to 'register' a new user through a form to create a new =
acl_user. But I cannot figure out how to let them login again using that =
name/password and be an AUTHENTICATED_USER with that acl_user =
name--other than Anonymous User. I tried to look at AUTHENTICATION_PATH, =
but my browser wants to download it--an empty file.
I can manage objects using dtml pretty well: create, delete, edit. If I =
can figure out how to authenticate a user, I would like to be able to =
add a property to new objects as they are created: =
(createdby:AUTHENTICATED_USER) so that I can control which objects get a =
checkbox (for delete) and an edit link for a particular user. =
InOtherWords, if a user creates a object, I want that same person to be =
able to go back and delete or edit that object. Anyone else can see it, =
but they won't be able to delete or edit the object.
This confuses me: manage_addProperty takes (id, value, type and =
optionally REQUEST) as args. What is the id? Is it the ID of the object =
that you want to add a property to? Or is it the ID of the new property? =
The Zope Quick Reference doesn't say, but I think it is the property's =
ID.=20
I am trying to learn from looking at the Zope interface work. After =
submitting the add property form, the page url looks like this: =
appRoot/objectname/manage_addProperty. I see that the objectname is =
behind manage_addProperty, I know the value, id and type are passed in =
the REQUEST. How can I take advantage of this following a line like:
<dtml-call expr=3D"manage_addImage(id=3Dtitle, file=3Dfile, =
title=3Dtitle)">
...to add a property to that image?
I found some useful tidbits at a howto page on Zope site somewhere. But =
it was pretty sparse and just whetted my appetite. I am coming from =
NT/IIS ASP world. So I am struggling. Can anyone point me to a richer =
source of samples that will help me get up this hill?
Thanks,
Richard
