C<assign_attributes> function and saves the object afterwards. Returns
the object itself.
+=item C<update_collection $attribute, $entries, %params>
+
+Updates a one-to-many relationship named C<$attribute> to match the
+entries in C<$entries>. C<$entries> is supposed to be an array ref of
+hash refs.
+
+For each hash ref in C<$entries> that does not contain a field for the
+relationship's primary key column, this function creates a new entry
+in the database with its attributes set to the data in the entry.
+
+For each hash ref in C<$entries> that contains a field for the
+relationship's primary key column, this function looks up the
+corresponding entry in C<$self->$attribute> & updates its
+attributes with the data in the entry.
+
+All objects in C<$self->$attribute> for which no corresponding
+entry exists in C<$entries> are deleted by calling the object's
+C<delete> method.
+
+In all cases the relationship itself C<$self->$attribute> is not
+changed.
+
=item _get_manager_class
Returns the manager package for the object or class that it is called
caches them for the duration of the current request (see
L<SL::Request/cache>).
+If you know in advance that you will likely need all objects of a
+particular type then you can pre-cache them by calling the manager's
+C<cache_all> function. For example, if you expect to need all unit
+objects, you can use C<SL::DB::Manager::Unit-E<gt>cache_all> before
+you start the actual work. Later you can use
+C<SL::DB::Unit-E<gt>load_cached> to retrieve individual objects and be
+sure that they're already cached.
+
This method can be called both as an instance method and a class
method. It loads objects for the corresponding class (e.g. both
C<SL::DB::Part-E<gt>load_cached(…)> and
will also skip setting the following fields if such columns exist for
C<$self>: C<itime>, C<mtime>.
+=item C<presenter>
+
+Returns a proxy wrapper that will dispatch all method calls to the presenter
+with the same name as the class of the involking object.
+
+For the full documentation about its capabilites see
+L<SL::DB::Helper::Presenter>
+
+=item C<as_debug_info>
+
+Returns a hash containing solely the essentials for dumping it with
+L<LXDebug/dump>. The returned hash consists of the column names with
+associated column values in stringified form.
