Rails 求助，比较两个 array 并排除
我有两个资料表
分别是
array1 = [ x= 'blue', 'y'='car' ]
array2 = [ x= 'blue', 'y'='book' ]
array3 = [ x= 'blue', 'y'='pen' ]
array0 = [ x= 'blue', 'y'='car, house, egg, book, ,pen' ]
想要的结果是
arraywant = [ x= 'blue', 'y'=' house, egg']
请指点指点
你这里的 array 既不是 ruby 的数组也不是 hash 啊。我的大概思路：
ary=array0['y'].split ','
ary.delete array1['y'] if ary.inclued? array1['y']
ary.delete array2['y'] if ary.inclued? array2['y']
ary.delete array3['y'] if ary.inclued? array3['y']
arraywant={:x=>array0[:x],'y'=>ary.join(',')}
