124 SL::DB::Part: Model for the 'parts' table
128 This is a standard Rose::DB::Object based model and can be used as one.
132 Although the base class is called C<Part> we usually talk about C<Articles> if
133 we mean instances of this class. This is because articles come in three
138 =item Part - a single part
140 =item Service - a part without onhand, and without inventory accounting
142 =item Assembly - a collection of both parts and services
146 These types are sadly represented by data inside the class and cannot be
147 migrated into a flag. To work around this, each C<Part> object knows what type
148 it currently is. Since the type ist data driven, there ist no explicit setting
149 method for it, but you can construct them explicitly with C<new_part>,
150 C<new_service>, and C<new_assembly>. A Buchungsgruppe should be supplied in this
151 case, but it will use the default Buchungsgruppe if you don't.
153 Matching these there are assorted helper methods dealing with type:
155 =head2 new_part PARAMS
157 =head2 new_service PARAMS
159 =head2 new_assembly PARAMS
161 Will set the appropriate data fields so that the resulting instance will be of
162 tthe requested type. Since part of the distinction are accounting targets,
163 providing a C<Buchungsgruppe> is recommended. If none is given the constructor
164 will load a default one and set the accounting targets from it.
168 Returns the type as a string. Can be one of C<part>, C<service>, C<assembly>.
172 Tests if the current object is a part, a service or an
173 assembly. C<$type> must be one of the words 'part', 'service' or
174 'assembly' (their plurals are ok, too).
176 Returns 1 if the requested type matches, 0 if it doesn't and
177 C<confess>es if an unknown C<$type> parameter is encountered.
185 Shorthand for is_type('part') etc.
189 =head2 get_sellprice_info %params
191 Retrieves the C<sellprice> and C<price_factor_id> for a part under
192 different conditions and returns a hash reference with those two keys.
194 If C<%params> contains a key C<project_id> then a project price list
195 will be consulted if one exists for that project. In this case the
196 parameter C<country_id> is evaluated as well: if a price list entry
197 has been created for this country then it will be used. Otherwise an
198 entry without a country set will be used.
200 If none of the above conditions is met then the information from
203 =head2 get_ordered_qty %params
205 Retrieves the quantity that has been ordered from a vendor but that
206 has not been delivered yet. Only open purchase orders are considered.
210 Checks if this articke is used in orders, invoices, delivery orders or
213 =head2 buchungsgruppe BUCHUNGSGRUPPE
215 Used to set the accounting informations from a L<SL:DB::Buchungsgruppe> object.
216 Please note, that this is a write only accessor, the original Buchungsgruppe can
217 not be retrieved from an article once set.
