TypeError: no implicit conversion of Symbol into Integerが解決できません

Question

１月の配列から特定の日付のレコードのみを取得したいのですが、

] pry(#<Users::ReceptionsMonthController>)>[:receptions][:date_of_use]["2021-04-07"]
TypeError: no implicit conversion of Symbol into Integer

が出てしまいます。
恐れ入りますが、解決策を教えていただけますでしょうか。
宜しくお願い致します。

Answer 1

(#<Users::ReceptionsMonthController>)>[:receptions] は配列になっていますから、この直後の[] 中身は整数（もしくはto_iで整数になるもの）でなければなりません。なのに[:date_of_use]ですからそのエラーです。
必ず月初めから日付順に並んでいるのなら
(#<Users::ReceptionsMonthController>)>[:receptions][6]
それが保証できないなら
(#<Users::ReceptionsMonthController>)>[:receptions]find{|c| c[:date_of_use] == "2021-04-07" }
