801 $report->set_sort_indicator($column, $direction); # optional
802 $report->add_data($row1, $row2, @more_rows);
803 $report->generate_with_headers();
805 This creates a report object, sets a few columns, adds some data and generates a standard report.
806 Sorting of columns will be alphabetic, and options will be set to their defaults.
807 The report will be printed including table headers, html headers and http headers.
811 Imagine the following scenario:
812 There's a simple form, which loads some data from the database, and needs to print it out. You write a template for it.
813 Then there may be more than one line. You add a loop in the template.
814 Then there are some options made by the user, such as hidden columns. You add more to the template.
815 Then it lacks usability. You want it to be able to sort the data. You add code for that.
816 Then there are too many results, you need pagination, you want to print or export that data..... and so on.
818 The ReportGenerator class was designed because this exact scenario happened about half a dozen times in kivitendo.
819 It's purpose is to manage all those formating, culling, sorting, and templating.
820 Which makes it almost as complicated to use as doing the work for yourself.
826 =item new \%myconfig,$form,%options
828 Creates a new ReportGenerator object, sets all given options, and returns it.
830 =item set_columns %columns
832 Sets the columns available to this report.
834 =item set_column_order @columns
836 Sets the order of columns. Any columns not present here are appended in alphabetic order.
838 =item set_sort_indicator $column,$direction
840 Sets sorting ot the table by specifying a column and a direction, where the direction will be evaluated to ascending if true.
841 Note that this is only for displaying. The data has to be presented already sorted.
843 =item add_data \@data
845 =item add_data \%data
847 Adds data to the report. A given hash_ref is interpreted as a single line of data, every array_ref as a collection of lines.
848 Every line will be expected to be in a kay => value format. Note that the rows have to be already sorted.
849 ReportGenerator does only colum sorting on its own, and provides links to sorting and visual cue as to which column was sorted by.
853 Adds a separator line to the report.
855 =item add_control \%data
857 Adds a control element to the data. Control elements are an experimental feature to add functionality to a report the regular data cannot.
858 Every control element needs to set IS_CONTROL_DATA, in order to be recongnized by the template.
859 Currently the only control element is a colspan element, which can be used as a mini header further down the report.
863 Deletes all data filled into the report, but keeps options set.
865 =item set_options %options
867 Sets options. For an incomplete list of options, see section configuration.
869 =item set_options_from_form
871 Tries to import options from the $form object given at creation
873 =item set_export_options $next_sub,@variable_list
875 Sets next_sub and additional variables needed for export.
877 =item get_attachment_basename
879 Returns the set attachment_basename option, or 'report' if nothing was set. See configuration for the option.
881 =item generate_with_headers
883 Parses the report, adds headers and prints it out. Headers depend on the option 'output_format',
884 for example 'HTML' will add proper table headers, html headers and http headers. See configuration for this option.
886 =item get_visible_columns $format
888 Returns a list of columns that will be visible in the report after considering all options or match the given format.
890 =item html_format $value
892 Escapes HTML characters in $value and substitutes newlines with '<br>'. Returns the escaped $value.
894 =item prepare_html_content $column,$name,@column_headers
896 Parses the data, and sets internal data needed for certain output format. Must be called once before the template is invoked.
897 Should not be called extrenally, since all render and generate functions invoke it anyway.
899 =item generate_html_content
901 The html generation function. Is invoked by generate_with_headers.
903 =item generate_pdf_content
905 The PDF generation function. It is invoked by generate_with_headers and renders the PDF with the PDF::API2 library.
907 =item generate_csv_content
909 The CSV generation function. Uses XS_CSV to parse the information into csv.
915 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.
917 =head2 General Options
921 =item std_column_visibility
923 Standard column visibility. Used if no visibility is set. Use this to save the trouble of enabling every column. Default is no.
927 Output format. Used by generate_with_headers to determine the format. Supported options are HTML, CSV, and PDF. Default is HTML.
929 =item allow_pdf_export
931 Used to determine if a button for PDF export should be displayed. Default is yes.
933 =item allow_csv_export
935 Used to determine if a button for CSV export should be displayed. Default is yes.
939 The template to be used for HTML reports. Default is 'report_generator/html_report'.
941 =item controller_class
943 If this is used from a C<SL::Controller::Base> based controller class, pass the
944 class name here and make sure C<SL::Controller::Helper::ReportGenerator> is
945 used in the controller. That way the exports stay functional.
955 Paper size. Default is a4. Supported paper sizes are a3, a4, a5, letter and legal.
957 =item orientation (landscape)
959 Landscape or portrait. Default is landscape.
963 Default is Verdana. Supported font names are Courier, Georgia, Helvetica, Times and Verdana. This option only affects the rendering with PDF::API2.
967 Default is 7. This option only affects the rendering with PDF::API2.
977 The paper margins in cm. They all default to 1.5.
981 Set to a true value if the pages should be numbered. Default is 1.
985 If set then the resulting PDF will be output to a printer. If not it will be downloaded by the user. Default is no.
1003 Character to enclose entries. Default is double quote (").
1007 Character to separate entries. Default is semicolon (;).
1011 Character to escape the quote_char. Default is double quote (").
1015 End of line style. Default is Unix.
1019 Include headers? Default is yes.
