我明白如何在rails控制檯中運行一段簡單的代碼。說rails console - 運行一段代碼
Swimming::Student.create(:name="Jerry")
如何運行一個大的一段代碼(多線)
Swimming::Student.all.each{ |student|
student.attended = flase
student.save
}

只需點擊進入,你會期望:
$rails c
Loading development environment (Rails 3.2.13)
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
只需輸入它這樣。整個塊被執行,一旦完成
另外,分號:'Product.all.each {| P |把p; p.shown = true} – Narfanator
