90 SL::DB::Object: Base class for all of our model classes
94 This is the base class from which all other model classes are
95 derived. It contains functionality and settings required for all model
98 Several functions (e.g. C<make_manager_class>, C<init_db>) in this
99 class are used for setting up the classes / base classes used for all
100 model instances. They overwrite the functions from
107 =item assign_attributes %attributes
109 =item _assign_attributes %attributes
111 Assigns all elements from C<%attributes> to the columns by calling
112 their setter functions. The difference between the two functions is
113 that C<assign_attributes> protects primary key columns while
114 C<_assign_attributes> doesn't.
116 Both functions handle values that are empty strings by replacing them
117 with C<undef> for non-text columns. This allows the calling functions
118 to use data from HTML forms as the input for C<assign_attributes>
119 without having to remove empty strings themselves (think of
120 e.g. select boxes with an empty option which should be turned into
121 C<NULL> in the database).
123 =item update_attributes %attributes
125 Assigns the attributes from C<%attributes> by calling the
126 C<assign_attributes> function and saves the object afterwards. Returns
129 =item _get_manager_class
131 Returns the manager package for the object or class that it is called
132 on. Can be used from methods in this package for getting the actual
