filter_attributes(*selected) click to toggle source

Filters attributes by selected attribute names @note In some cases we want to easily get subset of model attributes @note Hash#slice requires Ruby >= 2.5.0 @param [Symbol] selected attribute names @return [Hash] new hash with selected attributes

  # we should use getters instead of direct accessing attributes hash

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This was added for a ActiveRecord like feel but has been outdated by ActiveModel API using {#persisted?}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

# File lib/fog/core/attributes.rb, line 182
def new_record?
  Fog::Logger.deprecation("#new_record? is deprecated, use !persisted? instead [light_black](#{caller.first})[/]")
  !persisted?
end
persisted?() click to toggle source

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

@return [Boolean]

# File lib/fog/core/attributes.rb, line 170
def persisted?
  !!identity
