Never record undo information for session or data import
for session, it may causes unlimited database size expansion while it makes no sense
to undo this kind of changes. For data import, they are created programatically hence
we may not want to undo this either.
Request and ResultSet methods
-----------------------------
Those are methods you'll find on both request objects and on
repository session.
Request methods
~~~~~~~~~~~~~~~
`URL handling`:
* `build_url(*args, **kwargs)`, returns an absolute URL based on the
given arguments. The *controller* supposed to handle the response,
can be specified through the first positional parameter (the
connection is theoretically done automatically :).
`Data formatting`:
* `format_date(date, date_format=None, time=False)` returns a string for a
date time according to instance's configuration
* `format_time(time)` returns a string for a date time according to
instance's configuration
`And more...`:
* `tal_render(template, variables)`, renders a precompiled page template with
variables in the given dictionary as context
Result set methods
~~~~~~~~~~~~~~~~~~
* `get_entity(row, col)`, returns the entity corresponding to the data position
in the *result set*
* `complete_entity(row, col, skip_bytes=True)`, is equivalent to `get_entity` but
also call the method `complete()` on the entity before returning it
