+SL::Controller::Part - Part CRUD controller
+
+=head1 DESCRIPTION
+
+Controller for adding/editing/saving/deleting parts.
+
+All the relations are loaded at once and saving the part, adding a history
+entry and saving CVars happens inside one transaction.  When saving the old
+relations are deleted and written as new to the database.

+
+=head1 PART_TYPES
+
+There are 4 different part types:
+
+=over 4
+
+=item C<part>
+
+The "default" part type.
+
+inventory_accno_id is set.
+
+=item C<service>
+
+Services can't be stocked.
+
+inventory_accno_id isn't set.
+
+=item C<assembly>
+
+Assemblies consist of other parts, services, assemblies or assortments. They
+aren't meant to be bought, only sold. To add assemblies to stock you typically
+have to make them, which reduces the stock by its respective components. Once
+an assembly item has been created there is currently no way to "disassemble" it
+again. An assembly item can appear several times in one assembly. An assmbly is
+sold as one item with a defined sellprice and lastcost. If the component prices
+change the assortment price remains the same. The assembly items may be printed
+in a record if the item's "bom" is set.
+
+=item C<assortment>
+
+Similar to assembly, but each assortment item may only appear once per
+assortment. When selling an assortment the assortment items are added to the
+record together with the assortment, which is added with sellprice 0.
+
+Technically an assortment doesn't have a sellprice, but rather the sellprice is
+determined by the sum of the current assortment item prices when the assortment
+is added to a record. This also means that price rules and customer discounts
+will be applied to the assortment items.
+
+Once the assortment items have been added they may be modified or deleted, just
+as if they had been added manually, the individual assortment items aren't
+linked to the assortment or the other assortment items in any way.

+=item C<action_add_service>
+
+=item C<action_add_assembly>
+
+=item C<action_add_assortment>
+
+=item C<action_add PART_TYPE>
+
+An alternative to the action_add_$PART_TYPE actions, takes the mandatory
+parameter part_type as an action. Example:
+
+  controller.pl?action=Part/add&part_type=service
+
+=item C<action_add_from_record>
+
+When adding new items to records they can be created on the fly if the entered
+partnumber or description doesn't exist yet. After being asked what part type
+the new item should have the user is redirected to the correct edit page.
+
+Depending on whether the item was added from a sales or a purchase record, only
+the relevant part classifications should be selectable for new item, so this
+parameter is passed on via a hidden parts_classification_type in the new_item
+template.
+
+=item C<action_save>
+
+Saves the current part and then reloads the edit page for the part.
+
+=item C<action_use_as_new>
+
+Takes the information from the current part, plus any modifications made on the
+page, and creates a new edit page that is ready to be saved. The partnumber is
+set empty, so a new partnumber from the number range will be used if the user
+doesn't enter one manually.
+
+Unsaved changes to the original part aren't updated.
+
+The part type cannot be changed in this way.

+When submitting the form for saving, parses the transmitted form. Expects the
+following data:
+
+ $::form->{part}
+ $::form->{makemodels}
+ $::form->{translations}
+ $::form->{prices}
+ $::form->{assemblies}
+ $::form->{assortments}
+
+CVar data is currently stored directly in $::form, e.g. $::form->{cvar_size}.
+
+=item C<recalc_item_totals %params>
+
+Helper function for calculating the total lastcost and sellprice for assemblies
+or assortments according to their items, which are parsed from the current
+$::form.
+
+Is called whenever the qty of an item is changed or items are deleted.
+
+Takes two params:
+
+* part_type : 'assortment' or 'assembly' (mandatory)
+
+* price_type: 'lastcost' or 'sellprice', default is 'sellprice'
+
+Depending on the price_type the lastcost sum or sellprice sum is returned.
+
+Doesn't work for recursive items.

+
+* assortment items

+
+which parse $::form and automatically create an array of objects.
+
+These inits are used during saving and each time a new element is added.
+
+=over 4
+
+=item C<init_makemodels>
+
+Parses $::form->{makemodels}, creates an array of makemodel objects and stores them in
+$self->part->makemodels, ready to be saved.
+
+Used for saving parts and adding new makemodel rows.
+
+=item C<parse_add_items_to_objects PART_TYPE>
+
+Parses the resulting form from either the part-picker submit or the multi-item
+submit, and creates an arrayref of assortment_item or assembly objects, that
+can be rendered via C<render_assortment_items_to_html> or
+C<render_assembly_items_to_html>.
+
+Mandatory param: part_type: assortment or assembly (the resulting html will differ)
+Optional param: position (used for numbering and listrow class)
+
+=item C<render_assortment_items_to_html ITEM_OBJECTS>
+
+Takes an array_ref of assortment_items, and generates tables rows ready for
+adding to the assortment table.  Is used when a part is loaded, or whenever new
+assortment items are added.
+
+=item C<parse_form_makemodels>
+
+Makemodels can't just be overwritten, because of the field "lastupdate", that
+remembers when the lastcost for that vendor changed the last time.
+
+So the original values are cloned and remembered, so we can compare if lastcost
+was changed in $::form, and keep or update lastupdate.
+
+lastcost isn't updated until the first time it was saved with a value, until
+then it is empty.
+
+Also a boolean "makemodel" needs to be written in parts, depending on whether
+makemodel entries exist or not.
+
+We still need init_makemodels for when we open the part for editing.
