Constructors
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">
Class methods
Returns all attribute keys.
Changefeed at row (if id passed) or whole table level.
Returns a ChangeFeed instance which can be used to invoke async callbacks via on or
use blocking Iterator via each method.

api_key_id getter
api_key_id 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
api_key_id's default value
Edges authenticate with an X-API-KEY
Include api_key_id in the set of changed attributes, whether it has changed or not.
Generate code to apply default values
Assign to multiple attributes.
Assign to multiple attributes via HTTP::Params.
Assign to multiple attributes from a model object
Assign each field from JSON if field exists in JSON and has changed in model
Uses the YAML parser as JSON is valid YAML
Returns a Hash of all attribute values
Returns a NamedTuple of all attribute values.

Reset changes for all attributes.

Include online in the set of changed attributes, whether it has changed or not.
Returns a Hash of all attributes that can be persisted.
Reset each attribute to their previous values and clears all changes.
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::RecordNotSavedif record was destroyedPgORM::Error::RecordInvalidif validation failsPgORM::Error::RecordNotSavedif database operation fails
