default
value provided to attribute
without a block RB-W1014Attribute class methods that specify a :default
option whose value is an array, string literal or method call should do so by providing a lambda. All other values, such as string, symbol, integer and float literals as well as constants are acceptable as is.
This is so because if you don't provide a lambda, the default value provided will only be executed while the db migration is run and set as a constant value. When you provide a lambda, this default value is dynamic and gets set when you commit save the model to the database.
