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