items: [
%{title: "title1", code: "code1"},
%{title: "title2", code: "code2"},
%{title: "title3", code: "code3"}
]
},
%{
name: "name2",
items: [
%{title: "title4", code: "code4"},
%{title: "title5", code: "code5"},
%{title: "title6", code: "code6"},
%{title: "title7", code: "code7"},
%{title: "title8", code: "code8"}
]
}
]
|> ListToCsv.parse(header: [
{"名前", :name}, # simple get
{"アイテム#名", [:items, :N, :title]} # nested
{"アイテム#コード", [:items, :N, :code]},
{"item overflow?", [:items, &(length(&1) > 4)]} # function
], length: [items: 4])
=> [
["名前", "アイテム1名", "アイテム1コード", "アイテム2名",
"アイテム2コード", "アイテム3名", "アイテム3コード",
"アイテム4名", "アイテム4コード", "item overflow?"],
["name1", "title1", "code1", "title2", "code2", "title3", "code3", "", "",
"false"],
["name2", "title4", "code4", "title5", "code5", "title6", "code6", "title7",
"code7", "true"]
