我正在尝试从SQL Server中的表中获取数据并将其转换为JSON格式。我使用Marshmallow实现了对基本JSON格式的转换。我没有广泛使用JSON。要求是将其转换为分层JSON格式，如下所示：
必需的JSON格式：
{
"Year" : [{
"2016" : [{
"Q1" : [{
"Jan" : [{
"Week1" : [{
"Sunday" : [1,2,3],
"Monday" : [1,2,3],
"Tuesday" : [1,2,3],
"Wednesday" : [1,2,3],
"Thursday" : [1,2,3],
"Friday" : [1,2,3],
"Saturday" : [1,2,3]
}],
"Week2" : [{
"Sunday" : [1,2,3],
"Monday" : [1,2,3],
"Tuesday" : [1,2,3],
"Wednesday" : [1,2,3],
"Thursday" : [1,2,3],
"Friday" : [1,2,3],
"Saturday" : [1,2,3]
}],
"Week3" : [{
"Sunday" : [1,2,3],
"Monday" : [1,2,3],
"Tuesday" : [1,2,3],
"Wednesday" : [1,2,3],
"Thursday" : [1,2,3],
"Friday" : [1,2,3],
"Saturday" : [1,2,3]
}],
"Week4" : [{
"Sunday" : [1,2,3],
"Monday" : [1,2,3],
"Tuesday" : [1,2,3],
"Wednesday" : [1,2,3],
"Thursday" : [1,2,3],
"Friday" : [1,2,3],
"Saturday" : [1,2,3]
}],
}],
}],
}],
}],
}
我已经从表中读取数据，创建了一些函数并且已经实现了这种格式：
示例实现格式：
[{"sent_year": 2017, "sent_quarter": 4, "sent_month": "December", "sent_week": "Week5", "sent_day": "Sunday", "application_name": "App Two", "sent_score": "3"},
{"sent_year": 2017, "sent_quarter": 4, "sent_month": "December", "sent_week": "Week5", "sent_date": "Monday", "application_name": "App One", "sent_score": "1"},
{"sent_year": 2017, "sent_quarter": 4, "sent_month": "December", "sent_week": "Week5", "sent_date": "Tuesday", "application_name": "App Two", "sent_score": "3"},
{"sent_year": 2016, "sent_quarter": 4, "sent_month": "December", "sent_week": "Week5", "sent_date": "Wednesday", "application_name": "App One", "sent_score": "2"},
{"sent_year": 2016, "sent_quarter": 4, "sent_month": "December", "sent_week": "Week5", "sent_date": "Thursday", "application_name": "App Two", "sent_score": "1"},
{"sent_year": 2016, "sent_quarter": 4, "sent_month": "December", "sent_week": "Week5", "sent_date": "Friday", "application_name": "App One", "sent_score": "4"}]
由于这涉及基于价值的数据分组，我无法弄清楚如何继续。请帮忙。
