''' A Roundup-specific PageTemplate.
Interrogate the client to set up the various template variables to
be available:
- *class*
- The current class of node being displayed as an HTMLClass
- instance.
- *item*
- The current node from the database, if we're viewing a specific
- node, as an HTMLItem instance. If it doesn't exist, then we're
- on a new item page.
- (*classname*)
- this is one of two things:
-
- 1. the *item* is also available under its classname, so a *user*
- node would also be available under the name *user*. This is
- also an HTMLItem instance.
- 2. if there's no *item* then the current class is available
- through this name, thus "user/name" and "user/name/menu" will
- still work - the latter will pull information from the form
- if it can.
- *form*
- The current CGI form information as a mapping of form argument
- name to value
+ *context*
+ this is one of three things:
+ 1. None - we're viewing a "home" page
+ 2. The current class of item being displayed. This is an HTMLClass
+ instance.
+ 3. The current item from the database, if we're viewing a specific
+ item, as an HTMLItem instance.
*request*
Includes information about the current request, including:
- the url
``properties``, etc) parsed out of the form.
- methods for easy filterspec link generation
- *user*, the current user node as an HTMLItem instance
+ - *form*, the current CGI form information as a FieldStorage
*instance*
The current instance
*db*
The current database, through which db.config may be reached.
-
- Maybe also:
-
- *modules*
- python modules made available (XXX: not sure what's actually in
- there tho)
