[EP-tech] How to delete succeeds-field?
Hi Thomas and Yuri,
I think the following fix to line 1744 of
/opt/eprints3/perl_lib/EPrints/DataObj/EPrint.pm for EPrints 3.4.2 will
resolve your main problem:
if( *defined $parent &&* $parent->get_value( "eprint_status" ) eq
"archive" )
This is inside the code block for the in_thread function.? It changes:
sub in_thread
{
??? my( $self, $field ) = @_;
??????? if( $self->later_in_thread( $field )->count > 0 )
??????? {
??????????????? return 1;
??????? }
??????? if( $self->is_set( $field->name ) )
??????? {
??????????????? my $parentid = $self->get_value( $field->name );
??????????????? my $dataset = $self->{session}->dataset( "eprint" );
??????????????? my $parent = $dataset->dataobj( $parentid );
??????????????? if( $parent->get_value( "eprint_status" ) eq "archive" )
??????????????? {
??????????????????????? return 1;
??????????????? }
??????? }
}
To:
sub in_thread
{
??? my( $self, $field ) = @_;
??????? if( $self->later_in_thread( $field )->count > 0 )
??????? {
??????????????? return 1;
??????? }
??????? if( $self->is_set( $field->name ) )
??????? {
??????????????? my $parentid = $self->get_value( $field->name );
??????????????? my $dataset = $self->{session}->dataset( "eprint" );
??????????????? my $parent = $dataset->dataobj( $parentid );
??????????????? if( defined $parent && $parent->get_value(
"eprint_status" ) eq "archive" )
??????????????? {
??????????????????????? return 1;
??????????????? }
??????? }
}
I further tested with deleting the middle item (151) of three items where:
152 -succeeds-> 151 -succeeds-> 98
This breaks the chain which means neither 152 nor 98 displays the
"Available Versions of this Item" section on their abstract pages but
the fix to try to tie the chain together back together felt like
something overly complicate to implement and may deal with this case but
might break in other scenarios yet to be considered.? So as deletion of
151 does not leave anything horribly broken with the fix I have
introduced in 3.4.3, I thought it best to leave this along.? In
combination with the improvement to prevent previously live items from
being fully deleted, the chances of this breaking horribly in future is
much more limited.? Although retiring 151 as opposed to completely
deleting it, will have the same effect on the "Available Versions of
this Item" sections for 152 and 98.

David Newman
