ruby-on-rails - rails console - 运行一段代码

Question

我了解如何在 Rails 控制台中运行一段简单的代码。说

 Swimming::Student.create(:name="Jerry")

我如何运行一大段代码(很多行)

 Swimming::Student.all.each{ |student|
     student.attended = flase
     student.save
 }

Answer 1

如您所料，只需按回车键:

$rails c

2.0.0p0 :001 > Student.all.each do |student| #enter
2.0.0p0 :002 >     puts student #enter
2.0.0p0 :003?> end #enter
# here comes the output
