Question

我试图将一个：name，：date对播放到我的rails app中的一个表（通过seed.rd）...不太确定如何做到这一点..我的尝试如下：

[[ "New Years Day", 2013/01/01 ][ "Easter", 2013/03/31]].each do |holiday|
  Holiday.create!({:name, :date => holiday})
end

Answer 1

选项1：

[{ :name => "New Years Day", :date => "2013/01/01" },{ :name => "Easter", :date => "2013/03/31"}].each do |holiday|
  Holiday.create!(holiday)
end

选项2：

[[ "New Years Day", "2013/01/01" ],[ "Easter", "2013/03/31"]].each do |holiday|
  Holiday.create!({:name => holiday[0], :date => holiday[1]})
end

选项3（实际上并不是一个好的选项，因为当你超越名字和日期时它会变脏）：

{ "New Years Day" => "2013/01/01" , "Easter" => "2013/03/31"}.each do |holiday|
  Holiday.create!({:name => holiday.first, :date => holiday.second})
end

将数据对播种到rails app
