Passing a lot of variables into a mailer that I want to access from the view, so decided to dynamically set the instance variables from opts
Raw
opts_to_ivars.rb
class DynamicIvars
def greet(**options)
options.each { |k, v| instance_variable_set :"@#{k}", v }
p @hello
end
end
DynamicIvars.new.greet hello: "world"
# => "world"
