Detailed Description

Class represents a grading form definition used in a particular area.

General data about definition is stored in the standard DB table grading_definitions. A separate entry is created for each grading area (i.e. for each module). Plugins may define and use additional tables to store additional data about definitions.

Advanced grading plugins must declare a class gradingform_xxxx_controller extending this class and put it in lib.php in the plugin folder.

See gradingform_rubric_controller as an example

Except for overwriting abstract functions, plugin developers may want to overwrite functions responsible for loading and saving of the definition to include additional data stored.

Reimplemented in gradingform_guide_controller, and gradingform_rubric_controller.

◆ has_active_instances()

gradingform_controller::has_active_instances ( )

Returns true if there are already people who has been graded on this definition.

In this case plugins may restrict changes of the grading definition

Return values
boolean

◆ is_form_available()

gradingform_controller::is_form_available ( )

Is the grading form defined and ready for usage?

Return values
boolean

◆ is_form_defined()

gradingform_controller::is_form_defined ( )

Is the form definition record available?

Note that this actually checks whether the process of defining the form ever started and not whether the form definition should be considered as final.

Return values
boolean

◆ is_own_form()

gradingform_controller::is_own_form ( $userid = null)

Is the grading form owned by the given user?

The form owner is the user who created this instance of the form.

Is the grading form saved as a shared public template?

Return values
boolean

◆ load_definition()

gradingform_controller::load_definition ( )
protected

Loads the form definition if it exists.

The default implementation just tries to load the record from the {grading_definitions} table. The plugins are likely to override this with a more complex query that loads all required data at once.

Reimplemented in gradingform_guide_controller, and gradingform_rubric_controller.

◆ render_grade()

gradingform_controller::render_grade ( $page,
$itemid,
$gradinginfo,
$defaultcontent,

Return values
string

Reimplemented in gradingform_guide_controller, and gradingform_rubric_controller.

◆ render_preview()

gradingform_controller::render_preview ( moodle_page $page)
abstract

Returns the HTML code displaying the preview of the grading form.

Plugins are forced to override this. Ideally they should delegate the task to their own renderer.

Parameters
moodle_page$pagethe target page
Return values
string

Reimplemented in gradingform_guide_controller, and gradingform_rubric_controller.

◆ set_grade_range()

gradingform_controller::set_grade_range ( array $graderange,
$allowgradedecimals = false )
final

Sets the range of grades used in this area.

This is usually either range like 0-100 or the scale where keys start from 1.

Typically modules will call it: $controller->set_grade_range(make_grades_menu($gradingtype), $gradingtype > 0); Negative $gradingtype means that scale is used and the grade must be rounded to the nearest int. Positive $gradingtype means that range 0..$gradingtype is used for the grades and in this case grade does not have to be rounded.

Sometimes modules always expect grade to be rounded (like mod_assign does).

Parameters
array$graderangearray where first key is the minimum grade and the last key is the maximum grade.
bool$allowgradedecimalsif decimal values are allowed as grades.

◆ sql_search_from_tables()

static gradingform_controller::sql_search_from_tables ( $gdid)
static

Prepare the part of the search query to append to the FROM statement.

Parameters
string$gdidthe alias of grading_definitions.id column used by the caller
Return values
string

Reimplemented in gradingform_guide_controller, and gradingform_rubric_controller.

◆ sql_search_where()

static gradingform_controller::sql_search_where ( $token)
static

Prepare the parts of the SQL WHERE statement to search for the given token.

The returned array cosists of the list of SQL comparions and the list of respective parameters for the comparisons. The returned chunks will be joined with other conditions using the OR operator.

Parameters
string$tokentoken to search for
Return values
array

Reimplemented in gradingform_guide_controller, and gradingform_rubric_controller.

◆ update_definition()

gradingform_controller::update_definition ( stdClass $definition,
$usermodified = null )

Saves the defintion data into the database.

The implementation in this base class stores the common data into the record into the {grading_definition} table. The plugins are likely to extend this and save their data into own tables, too.

Parameters
stdClass$definitiondata containing values for the {grading_definition} table
int | null$usermodifiedoptional userid of the author of the definition, defaults to the current user

Reimplemented in gradingform_guide_controller, and gradingform_rubric_controller.
