◆ __call()

core_competency\persistent::__call ( $method,
$arguments )
finalinherited

protectedinherited

Hook to execute before a delete.

This is only intended to be used by child classes, do not put any logic here!

Return values
void

Reimplemented in core_reportbuilder\local\models\report, mod_bigbluebuttonbn\recording, quizaccess_seb\seb_quiz_settings, tool_dataprivacy\contextlevel, tool_dataprivacy\purpose, and tool_dataprivacy\purpose_override.

◆ before_update()

core\persistent::before_update ( )
protectedinherited

Hook to execute before an update.

Please note that at this stage the data has already been validated and therefore any new data being set will not be validated before it is sent to the database.

This is only intended to be used by child classes, do not put any logic here!

◆ extract_record()

static core\persistent::extract_record ( $row,
$prefix = null )
staticinherited

Extract a record from a row of data.

Most likely used in combination with self::get_sql_fields(). This method is simple enough to be used by non-persistent classes, keep that in mind when modifying it.

e.g. persistent\extract_record($row, 'user'); should work.

Parameters
stdClass$rowThe row of data.
string$prefixThe prefix the data fields are prefixed with, defaults to the table name followed by underscore.
Return values
stdClassThe extracted data.

◆ from_record()

core\persistent::from_record ( stdClass $record)
finalinherited

Populate this class with data from a DB record.

Note that this does not use any custom setter because the data here is intended to represent what is stored in the database.

Parameters
stdClass$recordA DB record.
Return values
static

◆ get()

core\persistent::get ( $property)
finalinherited

Data getter.

This is the main getter for all the properties. Developers can implement their own getters (get_propertyname) and they will be called by this function. Custom getters can use raw_get to get the raw value. Internally this is not used by self::to_record() or self::from_record() because the data is not expected to be validated or changed when reading/writing raw records from the DB.

Parameters
string$propertyThe property name.
Return values
mixed

Parameters
string$aliasThe alias used for the table.
string$prefixThe prefix to use for each field, defaults to the table name followed by underscore.
Return values
stringThe SQL fragment.

◆ has_property()

Parameters
string$propertyThe property name.
Return values
boolean

◆ is_property_required()

staticfinalinherited

Returns whether or not a property is required.

By definition a property with a default value is not required.

Parameters
string$propertyThe property name.

finalinherited

Returns whether or not the model is valid.

Return values
booleanTrue when it is.

◆ properties_definition()

Get the properties definition of this model.

Return values
array

◆ properties_filter()

static core\persistent::properties_filter ( stdClass $record)
staticfinalinherited

For a given record, return an array containing only those properties that are defined by the persistent.

Parameters
stdClass$record
Return values
array

◆ raw_get()

core\persistent::raw_get ( $property)
finalprotectedinherited

Internal Data getter.

This is the main getter for all the properties. Developers can implement their own getters but they should be calling self::get() in order to retrieve the value. Essentially the getters defined by the developers would only ever be used as helper methods and will not be called internally at this stage. In other words, do not expect self::to_record() or self::from_record() to use them.

This is protected because it is only for raw low level access to the data fields. Note this function is named raw_get and not get_raw to avoid naming clashes with a property named raw.

Parameters
string$propertyThe property name.
Return values
mixed

◆ raw_set()

core\persistent::raw_set ( $property,
$value )
finalprotectedinherited

Data setter.

This is the main setter for all the properties. Developers can implement their own setters but they should always be calling self::set() in order to set the value. Essentially the setters defined by the developers are helper methods and will not be called internally at this stage. In other words do not expect self::to_record() or self::from_record() to use them.

This is protected because it is only for raw low level access to the data fields.

Parameters
string$propertyThe property name.
mixed$valueThe value.
Return values
$this

◆ read()

core\persistent::read ( )
finalinherited

Load the data from the DB.

Return values
static

◆ record_exists()

static core\persistent::record_exists ( $id)
staticinherited

Check if a record exists by ID.

Parameters
int$idRecord ID.
Return values
bool

◆ record_exists_select()

static core\persistent::record_exists_select ( $select,
array $params = null )
staticinherited

Check if a records exists.

Parameters
string$select
array$params
Return values
bool

◆ save()

core\persistent::save ( )
finalinherited

Saves the record to the database.

If this record has an ID, then self::update() is called, otherwise self::create() is called. Before and after hooks for create() or update() will be called appropriately.

Return values
void

◆ set()

core\persistent::set ( $property,
$value )
finalinherited

Data setter.

This is the main setter for all the properties. Developers can implement their own setters (set_propertyname) and they will be called by this function. Custom setters should call internal_set() to finally set the value. Internally this is not used self::to_record() or self::from_record() because the data is not expected to be validated or changed when reading/writing raw records from the DB.

Parameters
string$propertyThe property name.
Return values
$this
Exceptions
coding_exception

◆ set_desca()

core_competency\evidence::set_desca ( $value)
protected

Convenience method to set the description $a.

Parameters
mixed$value
Return values
mixed

◆ set_many()

core\persistent::set_many ( array $values)
finalinherited

Data setter for multiple properties.

Internally calls {

See also
set} on each property
Parameters
array$valuesArray of property => value elements
Return values
$this

◆ set_url()

core_competency\evidence::set_url ( $url)
protected

Convenience method handling moodle_urls.

Parameters
null | string | moodle_url$urlThe URL.

◆ to_record()

core\persistent::to_record ( )
finalinherited

Create a DB record from this class.

Note that this does not use any custom getter because the data here is intended to represent what is stored in the database.

Return values
stdClass

◆ update()

core\persistent::update ( )
finalinherited

Update the existing record in the DB.

Return values
boolTrue on success.

◆ validate()

core\persistent::validate ( )
finalinherited

Validates the data.

Developers can implement addition validation by defining a method as follows. Note that the method MUST return a lang_string() when there is an error, and true when the data is valid.

protected function validate_propertyname($value) { if ($value !== 'My expected value') { return new lang_string('invaliddata', 'error'); } return true }

It is OK to use other properties in your custom validation methods when you need to, however note they might not have been validated yet, so try not to rely on them too much.

Note that the validation methods should be protected. Validating just one field is not recommended because of the possible dependencies between one field and another,also the field ID can be used to check whether the object is being updated or created.

When validating foreign keys the persistent should only check that the associated model exists. The validation methods should not be used to check for a change in that relationship. The API method setting the attributes on the model should be responsible for that. E.g. On a course model, the method validate_categoryid will check that the category exists. However, if a course can never be moved outside of its category it would be up to the calling code to ensure that the category ID will not be altered.

Return values
array|trueReturns true when the validation passed, or an array of properties with errors.

◆ validate_actionuserid()

core_competency\evidence::validate_actionuserid ( $value)
protected

Validate the action user ID.

Parameters
int$valueA user ID.
Return values
true|lang_string

◆ validate_contextid()

core_competency\evidence::validate_contextid ( $value)
protected

Validate the context ID.

Parameters
int$value
Return values
true|lang_string

◆ validate_desca()

core_competency\evidence::validate_desca ( $value)
protected

Validate the description $a.

Parameters
string$value
Return values
true|lang_string

◆ validate_descidentifier()

core_competency\evidence::validate_descidentifier ( $value)
protected

Validate the description identifier.

Only validate string existence during create. If the string is removed later on we should not prevent this model from being updated. Alternatively we could check if the string has changed before performing the check but this overhead is not required for now. An evidence should usually never be updated anyway.

Parameters
string$value
Return values
true|lang_string

◆ validate_grade()

core_competency\evidence::validate_grade ( $value)
protected

Validate the grade.

For performance reason we do not validate that the grade is a valid item of the scale associated with the competency or framework.

Parameters
int$valueThe value.
Return values
true|lang_string

◆ validate_usercompetencyid()

core_competency\evidence::validate_usercompetencyid ( $value)
protected

Validate the user competency.

Parameters
int$value
Return values
true|lang_string

◆ verify_protected_methods()

core\persistent::verify_protected_methods ( )
finalprotectedinherited

This function is used to verify that custom getters and setters are declared as protected.

Persistent properties should always be accessed via get('property') and set('property', 'value') which will call the custom getter or setter if it exists. We do not want to allow inconsistent access to the properties.
