new_record?() click to toggle source

Returns true if a remote resource has not been assigned an identity.

This was added for a ActiveRecord like feel but has been outdated by ActiveModel API using {#persisted?}

@deprecated Use inverted form of {#persisted?} @return [Boolean]

Returns true if a remote resource has been assigned an identity and we can assume it has been persisted.

@return [Boolean]
