=head1 NAME
|
|
|
|
SL::DB::Part: Model for the 'parts' table
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
This is a standard Rose::DB::Object based model and can be used as one.
|
|
|
|
=head1 TYPES
|
|
|
|
Although the base class is called C<Part> we usually talk about C<Articles> if
|
|
we mean instances of this class. This is because articles come in three
|
|
flavours called:
|
|
|
|
=over 4
|
|
|
|
=item Part - a single part
|
|
|
|
=item Service - a part without onhand, and without inventory accounting
|
|
|
|
=item Assembly - a collection of both parts and services
|
|
|
|
=item Assortment - a collection of items (parts or assemblies)
|
|
|
|
=back
|
|
|
|
These types are sadly represented by data inside the class and cannot be
|
|
migrated into a flag. To work around this, each C<Part> object knows what type
|
|
it currently is. Since the type is data driven, there ist no explicit setting
|
|
method for it, but you can construct them explicitly with C<new_part>,
|
|
C<new_service>, C<new_assembly> and C<new_assortment>. A Buchungsgruppe should be supplied in this
|
|
case, but it will use the default Buchungsgruppe if you don't.
|
|
|
|
Matching these there are assorted helper methods dealing with types,
|
|
e.g. L</new_part>, L</new_service>, L</new_assembly>, L</type>,
|
|
L</is_type> and others.
|
|
|
|
=head1 FUNCTIONS
|
|
|
|
=over 4
|
|
|
|
=item C<new_part %PARAMS>
|
|
|
|
=item C<new_service %PARAMS>
|
|
|
|
=item C<new_assembly %PARAMS>
|
|
|
|
Will set the appropriate data fields so that the resulting instance will be of
|
|
the requested type. Since accounting targets are part of the distinction,
|
|
providing a C<Buchungsgruppe> is recommended. If none is given the constructor
|
|
will load a default one and set the accounting targets from it.
|
|
|
|
=item C<type>
|
|
|
|
Returns the type as a string. Can be one of C<part>, C<service>, C<assembly>.
|
|
|
|
=item C<is_type $TYPE>
|
|
|
|
Tests if the current object is a part, a service or an
|
|
assembly. C<$type> must be one of the words 'part', 'service' or
|
|
'assembly' (their plurals are ok, too).
|
|
|
|
Returns 1 if the requested type matches, 0 if it doesn't and
|
|
C<confess>es if an unknown C<$type> parameter is encountered.
|
|
|
|
=item C<is_part>
|
|
|
|
=item C<is_service>
|
|
|
|
=item C<is_assembly>
|
|
|
|
Shorthand for C<is_type('part')> etc.
|
|
|
|
=item C<get_sellprice_info %params>
|
|
|
|
Retrieves the C<sellprice> and C<price_factor_id> for a part under
|
|
different conditions and returns a hash reference with those two keys.
|
|
|
|
If C<%params> contains a key C<project_id> then a project price list
|
|
will be consulted if one exists for that project. In this case the
|
|
parameter C<country_id> is evaluated as well: if a price list entry
|
|
has been created for this country then it will be used. Otherwise an
|
|
entry without a country set will be used.
|
|
|
|
If none of the above conditions is met then the information from
|
|
C<$self> is used.
|
|
|
|
=item C<get_ordered_qty %params>
|
|
|
|
Retrieves the quantity that has been ordered from a vendor but that
|
|
has not been delivered yet. Only open purchase orders are considered.
|
|
|
|
=item C<get_taxkey %params>
|
|
|
|
Retrieves and returns a taxkey object valid for the given date
|
|
C<$params{date}> and tax zone C<$params{taxzone}>
|
|
(C<$params{taxzone_id}> is also recognized). The date defaults to the
|
|
current date if undefined.
|
|
|
|
This function looks up the income (for trueish values of
|
|
C<$params{is_sales}>) or expense (for falsish values of
|
|
C<$params{is_sales}>) account for the current part. It uses the part's
|
|
associated buchungsgruppe and uses the fields belonging to the tax
|
|
zone given by C<$params{taxzone}>.
|
|
|
|
The information retrieved by the function is cached.
|
|
|
|
=item C<get_chart %params>
|
|
|
|
Retrieves and returns a chart object valid for the given type
|
|
C<$params{type}> and tax zone C<$params{taxzone}>
|
|
(C<$params{taxzone_id}> is also recognized). The type must be one of
|
|
the three key words C<income>, C<expense> and C<inventory>.
|
|
|
|
This function uses the part's associated buchungsgruppe and uses the
|
|
fields belonging to the tax zone given by C<$params{taxzone}>.
|
|
|
|
The information retrieved by the function is cached.
|
|
|
|
=item C<used_in_record>
|
|
|
|
Checks if this article has been used in orders, invoices or delivery orders.
|
|
|
|
=item C<orphaned>
|
|
|
|
Checks if this article is used in orders, invoices, delivery orders or
|
|
assemblies.
|
|
|
|
=item C<buchungsgruppe BUCHUNGSGRUPPE>
|
|
|
|
Used to set the accounting information from a L<SL:DB::Buchungsgruppe> object.
|
|
Please note, that this is a write only accessor, the original Buchungsgruppe can
|
|
not be retrieved from an article once set.
|
|
|
|
=item C<get_simple_stock_sql>
|
|
|
|
Fetches the qty and the stock value for the current part for each bin and
|
|
warehouse where the part is in stock (or rather different from 0, might be
|
|
negative).
|
|
|
|
Runs some additional window functions to add the running totals (total running
|
|
total and total per warehouse) for qty and stock value to each line.
|
|
|
|
Using the LEAD(w.description) the template can check if the warehouse
|
|
description is about to change, i.e. the next line will contain numbers from a
|
|
different warehouse, so that a subtotal line can be added.
|
|
|
|
The last row will contain the running qty total (run_qty) and the running total
|
|
stock value (run_stock_value) over all warehouses/bins and can be used to add a
|
|
line for the grand totals.
|
|
|
|
=item C<items_lastcost_sum>
|
|
|
|
Non-recursive lastcost sum of all the items in an assembly or assortment.
|
|
|
|
=item C<get_stock %params>
|
|
|
|
Fetches stock qty in the default unit for a part.
|
|
|
|
bin_id and warehouse_id may be passed as params. If only a bin_id is passed,
|
|
the stock qty for that bin is returned. If only a warehouse_id is passed, the
|
|
stock qty for all bins in that warehouse is returned. If a shippingdate is
|
|
passed the stock qty for that date is returned.
|
|
|
|
Examples:
|
|
my $qty = $part->get_stock(bin_id => 52);
|
|
|
|
$part->get_stock(shippingdate => DateTime->today->add(days => -5));
