PlaceOS::Model::Survey::Question

macro level key => type

Deserializes the given JSON in string_or_io into an instance of self, assuming the JSON consists of an JSON object with key root, and whose value is the value to deserialize. Will not deserialise from fields with mass_assign: false

class User < ActiveModel::Model
  attribute name : String
  attribute google_id : UUID, mass_assign: false
end

User.from_json(%({"main": {"name": "Jason", "google_id": "f6f70bfb-c882-446d-8758-7ce47db39620"}}), root: "main") # => #<User:0x103131b20 @name="Jason">

choices getter

choices setter

NOTE: use getter / getter! (not property / property!) so that the setter defined later in __create_initializer__ is the only setter on the field. Crystal's overload resolution silently fails to replace a property-defined setter with one of identical signature for generic types (e.g. Set(String)?, Array(String)?, String | Array(String)), although it does work for non-generic ones like String?. Defining the setter only once via __create_initializer__ ensures change tracking, sanitization, and custom setter blocks run uniformly across all types.

Returns a Tuple of the previous and the current value of an instance variable if it has changed

choices's default value

Include choices in the set of changed attributes, whether it has changed or not.

Reset changes for all attributes.

created_at getter

NOTE: use getter / getter! (not property / property!) so that the setter defined later in __create_initializer__ is the only setter on the field.

Saves the record to the database, raising an exception on failure.

For new records, performs an INSERT. For existing records, performs an UPDATE. Only updates changed attributes (dirty tracking).

Example

user = User.new(name: "John")
user.save! # => #<User id: 1, name: "John">

user.name = "Jane"
user.save! # Only updates 'name' column

Raises

• PgORM::Error::RecordNotSaved if record was destroyed
• PgORM::Error::RecordInvalid if validation fails
• PgORM::Error::RecordNotSaved if database operation fails
