=head1 NAME

SL::DB::GLTransaction: Rose model for GL transactions (table "gl")

=head1 FUNCTIONS

=over 4

=item C<post>

Takes an unsaved but initialised GLTransaction object and saves it, but first
validates the object, sets certain defaults (e.g. employee), and then also runs
various checks, writes history, runs DATEV check, ...

Returns C<$self> on success and dies otherwise. The whole process is run inside
a transaction. If it fails then nothing is saved to or changed in the database.
A new transaction is only started if none are active.

Example of posting a GL transaction from scratch:

my $tax_0 = SL::DB::Manager::Tax->find_by(taxkey => 0, rate => 0.00);
my $gl_transaction = SL::DB::GLTransaction->new(
taxincluded => 1,
description => 'bar',
reference => 'bla',
transdate => DateTime->today_local,
)->add_chart_booking(
chart => SL::DB::Manager::Chart->find_by( description => 'Kasse' ),
credit => 100,
tax_id => $tax_0->id,
)->add_chart_booking(
chart => SL::DB::Manager::Chart->find_by( description => 'Bank' ),
debit => 100,
tax_id => $tax_0->id,
)->post;

=item C<add_chart_booking %params>

Adds an acc_trans entry to an existing GL transaction, depending on the tax it
will also automatically create the tax entry. The GL transaction already needs
to have certain values, e.g. transdate, taxincluded, ...

Mandatory params are

=over 2

=item * chart as an RDBO object

=item * tax_id

=item * either debit OR credit (positive values)

=back

Optional params:

=over 2

=item * dec - number of decimals to round to, defaults to 2

=item * source

=item * memo

=item * project_id

=back

All other values are taken directly from the GL transaction.

For an example, see C<post>.

After adding an acc_trans entry the GL transaction shouldn't be modified (e.g.
values affecting the acc_trans entries, such as transdate or taxincluded
shouldn't be changed). There is currently no method for recalculating the
acc_trans entries after they were added.

Return C<$self>, so it allows chaining.

=item C<validate>

Runs various checks to see if the GL transaction is ready to be C<post>ed.

Will return an array of error strings if any necessary conditions aren't met.
