I'am creating form (CRUD) based on formlib, but this
is supposed to work with relational database.
Design is simple:
content_object -> view(based on formlib.form)

My content_object gets data from RDBMS and stores
data into RDBMS. So I want to be able to call something like:
content_object/@@editview?row_id=1
to get and set data for row with row_id = 1 in RDBMS or
content_object/@@delview?row_id=2
to remove data from RDBMS etc.

Simply, I don't have x content objects that are
mappings of x rows in RDBMS, but I have one
object to do CRUD operations on every row in database.

content_object is responsible for calling sql statements
so it needs data from the request. Possibly I have to pass
them (or the whole request) from the view?

Hm... My doctest:

  >>> from zope.app.folder import rootFolder 
  >>> from zope.traversing.api import getPath
  >>> root = rootFolder()
  >>> root['test_content'] = test_content = DBCrudContent()
  >>> getPath(test_content)

and I get:

File "dbcrudbase.txt", line 83, in dbcrudbase.txt
Failed example:
    getPath(root['test_content'])
Exception raised:
    Traceback (most recent call last):

    TypeError: ('Could not adapt',

Ehm...? Ideas?
