將用戶正則表達式匹配輸入數據庫查詢

Question

class Database
  include Cinch::Plugin

  DB = SQLite3::Database.new('development.sqlite3')
  match /(select .* from gears where .* like .*)/i 

  def execute(m)
    @db = SQLite3::Database.new('development.sqlite3')
    #m.reply @db.execute("select * from gears where lab like 'Primary'") 
  end
end

IRC機器人的這一部分。 我正在嘗試將用戶輸入的匹配正則表達式直接輸入到@ db.execute，以執行查詢。 任何幫助或建議以不同的方式將不勝感激。

遵循以下原則應該可以：

def execute(m)
  @db = SQLite3::Database.new('development.sqlite3')
  input = m.input # or however you're getting the input into this function
  regex = /(select .* from gears where .* like .*)/i 
  db_query_string = regex.match(input).to_s
  m.reply @db.execute(db_query_string) 
end
