860 SL::ReportGenerator.pm: the kivitendo way of getting data in shape
864 my $report = SL::ReportGenerator->new(\%myconfig, $form);
865 $report->set_options(%options); # optional
866 $report->set_columns(%column_defs);
867 $report->set_sort_indicator($column, $direction); # optional
868 $report->add_data($row1, $row2, @more_rows);
869 $report->generate_with_headers();
871 This creates a report object, sets a few columns, adds some data and generates a standard report.
872 Sorting of columns will be alphabetic, and options will be set to their defaults.
873 The report will be printed including table headers, html headers and http headers.
877 Imagine the following scenario:
878 There's a simple form, which loads some data from the database, and needs to print it out. You write a template for it.
879 Then there may be more than one line. You add a loop in the template.
880 Then there are some options made by the user, such as hidden columns. You add more to the template.
881 Then it lacks usability. You want it to be able to sort the data. You add code for that.
882 Then there are too many results, you need pagination, you want to print or export that data..... and so on.
884 The ReportGenerator class was designed because this exact scenario happened about half a dozen times in kivitendo.
885 It's purpose is to manage all those formating, culling, sorting, and templating.
886 Which makes it almost as complicated to use as doing the work by yourself.
892 =item new \%myconfig,$form,%options
894 Creates a new ReportGenerator object, sets all given options, and returns it.
896 =item set_columns %columns
898 Sets the columns available to this report.
900 =item set_column_order @columns
902 Sets the order of columns. Any columns not present here are appended in alphabetic order.
904 =item set_sort_indicator $column,$direction
906 Sets sorting of the table by specifying a column and a direction, where the direction will be evaluated to ascending if true.
907 Note that this is only for displaying. The data has to have already been sorted when it was added.
909 =item add_data \@data
911 =item add_data \%data
913 Adds data to the report. A given hash_ref is interpreted as a single line of
914 data, every array_ref as a collection of lines. Every line will be expected to
915 be in a key => value format. Note that the rows have to already have been
918 The ReportGenerator is only able to display pre-sorted data and to indicate by
919 which column and in which direction the data has been sorted via visual clues
920 in the column headers. It also provides links to invert the sort direction.
924 Adds a separator line to the report.
926 =item add_control \%data
928 Adds a control element to the data. Control elements are an experimental feature to add functionality to a report the regular data cannot.
929 Every control element needs to set IS_CONTROL_DATA, in order to be recognized by the template.
930 Currently the only control element is a colspan element, which can be used as a mini header further down the report.
934 Deletes all data added to the report, but keeps options set.
936 =item set_options %options
938 Sets options. For an incomplete list of options, see section configuration.
940 =item set_options_from_form
942 Tries to import options from the $form object given at creation
944 =item set_export_options $next_sub,@variable_list
946 Sets next_sub and additional variables needed for export.
948 =item get_attachment_basename
950 Returns the set attachment_basename option, or 'report' if nothing was set. See configuration for the option.
952 =item generate_with_headers
954 Parses the report, adds headers and prints it out. Headers depend on the option 'output_format',
955 for example 'HTML' will add proper table headers, html headers and http headers. See configuration for this option.
957 =item get_visible_columns $format
959 Returns a list of columns that will be visible in the report after considering all options or match the given format.
961 =item html_format $value
963 Escapes HTML characters in $value and substitutes newlines with '<br>'. Returns the escaped $value.
965 =item prepare_html_content $column,$name,@column_headers
967 Parses the data, and sets internal data needed for certain output format. Must be called once before the template is invoked.
968 Should not be called externally, since all render and generate functions invoke it anyway.
970 =item generate_html_content
972 The html generation function. Is invoked by generate_with_headers.
974 =item generate_pdf_content
976 The PDF generation function. It is invoked by generate_with_headers and renders the PDF with the PDF::API2 library.
978 =item generate_csv_content
980 The CSV generation function. Uses XS_CSV to parse the information into csv.
986 These are known options and their defaults. Options for pdf export and csv export need to be set as a hashref inside the export option.
988 =head2 General Options
992 =item std_column_visibility
994 Standard column visibility. Used if no visibility is set. Use this to save the trouble of enabling every column. Default is no.
998 Output format. Used by generate_with_headers to determine the format. Supported options are HTML, CSV, and PDF. Default is HTML.
1000 =item allow_pdf_export
1002 Used to determine if a button for PDF export should be displayed. Default is yes.
1004 =item allow_csv_export
1006 Used to determine if a button for CSV export should be displayed. Default is yes.
1010 The template to be used for HTML reports. Default is 'report_generator/html_report'.
1012 =item controller_class
1014 If this is used from a C<SL::Controller::Base> based controller class, pass the
1015 class name here and make sure C<SL::Controller::Helper::ReportGenerator> is
1016 used in the controller. That way the exports stay functional.
1026 Paper size. Default is a4. Supported paper sizes are a3, a4, a5, letter and legal.
1028 =item orientation (landscape)
1030 Landscape or portrait. Default is landscape.
1034 Default is Verdana. Supported font names are Courier, Georgia, Helvetica, Times and Verdana. This option only affects the rendering with PDF::API2.
1038 Default is 7. This option only affects the rendering with PDF::API2.
1048 The paper margins in cm. They all default to 1.5.
1052 Set to a true value if the pages should be numbered. Default is 1.
1056 If set then the resulting PDF will be output to a printer. If not it will be downloaded by the user. Default is no.
1074 Character to enclose entries. Default is double quote (").
1078 Character to separate entries. Default is semicolon (;).
1082 Character to escape the quote_char. Default is double quote (").
1086 End of line style. Default is Unix.
1090 Include headers? Default is yes.
1094 Character encoding. Default is UTF-8.
