Question

我有一个包含3个字段的模型示例。

class Example(models.Model):
      name = models.CharField(max_length=200, null=False, blank=False)
      number = models.CharField(max_length=200, null=False, blank=False)
      address = models.CharField(max_length=200)`

我有一个Post API（其余框架）。这将有多个对象。我想解析这个数组并将每个对象存储在我的数据库中。这是Views.py

class PostExample(APIView):
    def post(self, request, format=None):
        example_records = request.POST["example_data"]
        print example_records

这里“example_data”是键，值将是一个数组。示例值：

[
  {
    "name": "test",
    "address": "address",
    "number": 123456789
  },
  {
    ...
  }
]

我无法遍历“example_records”。 “example_records”打印数组但无法从中获取每个对象。如何实现这个??

Answer 1

您可以在此处使用Sub Compare() 'Set primary Workbook 'Find last cell Dim WS As Worksheet Dim LastCellRowNumber As Long Set WS = ThisWorkbook.Sheets("Sheet1") LastCellRowNumber = WS.Cells(WS.Rows.Count, "A").End(xlUp).Row 'MsgBox (LastCell.Row) 'Adding Index Column WS.Columns("A:A").Insert Shift:=xlToRight WS.Range("A2:A" & LastCellRowNumber).Formula = "=G2&H2" 'adding headers WS.Range("AG1").Value = "Resale" WS.Range("AH1").Value = "Cost" WS.Range("AI1").Value = "disti" 'open company quotes Dim wbCompQuotes As Workbook Set wbCompQuotes = Workbooks.Open ("R:\company\DATA\company quotes.xlsx") 'find last cell' Dim wsQuoteSum As Worksheet Dim LastCellRowNumberq As Long Set wsQuoteSum = wbCompQuotes.Worksheets("Quote Summary") LastCellRowNumberq = wsQuoteSum.Cells(wsQuoteSum.Rows.Count, "A").End(xlUp).Row 'MsgBox (LastCell.Row) wsQuoteSum.Columns("A:A").Insert Shift:=xlToRight wsQuoteSum.Range("A2:A" & LastCellRowNumberq).Formula = "=J2&B2" Dim i As Long For i = 2 To LastCellRowNumber WS.Range("AG" & i) = Application.VLookup(WS.Range("A" & i), wsQuoteSum.Range("A2:AS" & LastCellRowNumberq), 17, False) WS.Range("AH" & i) = Application.VLookup(WS.Range("A" & i), wsQuoteSum.Range("A2:AS" & LastCellRowNumberq), 19, False) WS.Range("AI" & i) = Application.VLookup(WS.Range("A" & i), wsQuoteSum.Range("A2:AS" & LastCellRowNumberq), 20, False) Next i End Sub模块。首先将json字符串数据转换为example_records对象，然后解析json，最后遍历所有。

Example value

然后您可以通过传递相应的import json data = '''{"Example value":[{"name":"test1","address":"address1","number":123456789},{"name":"test2","address":"address2","number":123456789}]}''' jobject = json.loads(data) for val in jobject['Example value']: print(val) {'address': 'address1', 'name': 'test1', 'number': 123456789} {'address': 'address2', 'name': 'test2', 'number': 123456789}来简单地提取values，例如：

key

Answer 2

request.POST是POST期间收到的原始数据，它是一个json字符串。您可以按照某些用户的建议使用json模块，但Django Rest Framework可以为您完成工作：{{3}}。这就是使用像DRF这样的框架的重点。

class PostExample(APIView):
    def post(self, request, format=None):
        example_records = request.data["example_data"]
        for record in example_records:
            ...

Django Parse发布请求数据（JsonArray）
