/**
|
|
* Base "abstract" class creating reports on your data.
|
|
*
|
|
* Creating reports
|
|
* ================
|
|
*
|
|
* Creating a new report is a matter overloading a few key methods
|
|
*
|
|
* {@link title()}: Return the title - i18n is your responsibility
|
|
* {@link description()}: Return the description - i18n is your responsibility
|
|
* {@link sourceQuery()}: Return a DataObjectSet of the search results
|
|
* {@link columns()}: Return information about the columns in this report.
|
|
* {@link parameterFields()}: Return a FieldSet of the fields that can be used to filter this
|
|
* report.
|
|
*
|
|
* If you can't express your report as a query, you can implement the this method instead:
|
|
*
|
|
* // Return an array of fields that can be used to sort the data
|
|
* public function sourceRecords($params, $sort, $limit) { ... }
|
|
*
|
|
* The $sort value will be set to the corresponding key of the columns() array. If you wish to
|
|
* make only a subset of the columns sortable, then you can override `sortColumns()` to return a
|
|
* subset of the array keys.
|
|
*
|
|
* Note that this implementation is less efficient and should only be used when necessary.
|
|
*
|
|
* If you wish to modify the report in more extreme ways, you could overload these methods instead.
|
|
*
|
|
* {@link getReportField()}: Return a FormField in the place where your report's TableListField
|
|
* usually appears.
|
|
* {@link getCMSFields()}: Return the FieldSet representing the complete right-hand area of the
|
|
* report, including the title, description, parameter fields, and results.
|
|
*
|
|
* Showing reports to the user
|
|
* ===========================
|
|
*
|
|
* Right now, all subclasses of SS_Report will be shown in the ReportAdmin. However, we are planning
|
|
* on adding an explicit registration mechanism, so that you can decide which reports go in the
|
|
* report admin, and which go elsewhere (such as the side panel in the CMS).

* @package cms

|
* @subpackage reports
