Managing simple models

Simple models have their own list of methods for managing data.

• getValue($field) - extract the field value, described in more detail in the section Data output in the template, or use getter
• setValue($field, $value) - set the field value for subsequent use and/or update
• getEnumTitle($field) - get the name (not the key) of the enum type field
• loadIntoRecord() - extract all fields into the Record class object, the process is described in the section Data output in the template
• update() - update data of a simple model, no new version is written
• combineEmails([$fields]) - takes all fields of the email type and glues them together separated by commas, in the optional parameter you can pass the names of the fields that need to be returned as an array, if the argument is not passed, all filled fields of the email type will be returned.
