  28
  29 Koha::UploadedFiles - Koha::Objects class for uploaded files
  30
  31 =head1 SYNOPSIS
  32
  33     use Koha::UploadedFiles;
  34
  35     # get one upload
  36     my $upload01 = Koha::UploadedFiles->find( $id );
  37
  38     # get some uploads
  39     my @uploads = Koha::UploadedFiles->search_term({ term => '.mrc' });
  40
  41     # delete all uploads
  42     Koha::UploadedFiles->delete;
  43
  44 =head1 DESCRIPTION
  45
  46 Allows regular CRUD operations on uploaded_files via Koha::Objects / DBIx.
  47
  48 The delete method also takes care of deleting files. The search_term method
  49 provides a wrapper around search to look for a term in multiple columns.

  52
  53 =head2 INSTANCE METHODS
  54
  55 =head3 delete
  56
  57 Delete uploaded files.
  58 Returns true if no errors occur. (So, false may mean partial success.)
  59
  60 Parameter keep_file may be used to delete records, but keep files.

  64 sub delete {
  65     my ( $self, $params ) = @_;
  66     # We use the individual delete on each resultset record
  67     my $err = 0;
  68     while( my $row = $self->_resultset->next ) {
  69         my $kohaobj = Koha::UploadedFile->_new_from_dbic( $row );
  70         $err++ if !$kohaobj->delete( $params );
  71     }
  72     return $err==0;
  73 }
  74
  75 =head3 search_term
  76
  77 Search_term allows you to pass a term to search in filename and hashvalue.
  78 If you do not pass include_private, only public records are returned.
  79
  80 Is only a wrapper around Koha::Objects search. Has similar return value.

  90     }
  91     return $self->search(
  92         [ { filename => { like => '%'.$term.'%' }, %public },
  93           { hashvalue => { like => '%'.$params->{term}.'%' }, %public } ],
