160 SL::DB::Object: Base class for all of our model classes
164 This is the base class from which all other model classes are
165 derived. It contains functionality and settings required for all model
168 Several functions (e.g. C<make_manager_class>, C<init_db>) in this
169 class are used for setting up the classes / base classes used for all
170 model instances. They overwrite the functions from
177 =item assign_attributes %attributes
179 =item _assign_attributes %attributes
181 Assigns all elements from C<%attributes> to the columns by calling
182 their setter functions. The difference between the two functions is
183 that C<assign_attributes> protects primary key columns while
184 C<_assign_attributes> doesn't.
186 Both functions handle values that are empty strings by replacing them
187 with C<undef> for non-text columns. This allows the calling functions
188 to use data from HTML forms as the input for C<assign_attributes>
189 without having to remove empty strings themselves (think of
190 e.g. select boxes with an empty option which should be turned into
191 C<NULL> in the database).
193 =item update_attributes %attributes
195 Assigns the attributes from C<%attributes> by calling the
196 C<assign_attributes> function and saves the object afterwards. Returns
199 =item _get_manager_class
201 Returns the manager package for the object or class that it is called
202 on. Can be used from methods in this package for getting the actual
205 =item C<call_sub $name, @args>
207 Calls the sub C<$name> on C<$self> with the arguments C<@args> and
208 returns its result. This is meant for situations in which the sub's
209 name is a composite, e.g.
211 my $chart_id = $buchungsgruppe->call_sub(($is_sales ? "income" : "expense") . "_accno_id_${taxzone_id}");
213 =item C<call_sub_if $name, $check, @args>
215 Calls the sub C<$name> on C<$self> with the arguments C<@args> if
216 C<$check> is trueish. If C<$check> is a code reference then it will be
217 called with C<$self> as the only argument and its result determines
218 whether or not C<$name> is called.
220 Returns the sub's result if the check is positive and C<$self>
