自學(xué)it吧論壇訂單實(shí)做1step建立結(jié)帳頁(yè)

1、在購(gòu)物車按下 確認(rèn)結(jié)帳 按鈕后可以顯示結(jié)帳明細(xì)， 并且可以讓消費(fèi)者輸入寄送地址目標(biāo)8-1 Step 1 :建立結(jié)帳頁(yè)修改 app/ views/ carts/ index. html. erbStep 1 :建立結(jié)帳頁(yè) routinggit checkout - b story 5Step 0 :步驟db/ migrate/( 一堆數(shù)字) _create_orders. rbclass Create Orders Active Record: Migration 5 . 0 def changecreate_table : orders do |t|+t.eger : total, defau
