用於將model例項轉換為dict

1 from django.forms.models import model_to_dict
2 di = model_to_dict(order, exclude=［'create_time', 'update_time'］)

原始碼函式宣告：def model_to_dict(instance, fields=None, exclude=None):
其中引數instance是物件例項，fields是指定需要哪些欄位，exclude是指定排除哪些欄位，exclude比fields優先順序高。

model_to_dict的一個應用

 1 def
 
 case_set_new(req):
 2     if req.method == 'GET':
 3         case_sets = models.CaseSet.objects.filter(is_delete=False)
 4         data = []
 5         for c in case_sets:
 6             d = model_to_dict(c)
 7             data.append(d)
 8         response = {'code': 0, 'msg': '新增成功', 'data': data}
 
 9         return JsonResponse(response, json_dumps_params={'ensure_ascii': False})  # 漢字不轉義
10     elif req.method == 'POST':
11         name = req.POST.get('name')
12         desc = req.POST.get('desc')
13         if name.strip() and desc.strip():
14             models.CaseSet.objects.create(name=name, desc=desc)
 
15             data = {'code': 0, 'msg': '新增成功'}
16         else:
17             data = {'code': -1, 'msg': '引數錯誤'}
18         return JsonResponse(data)  # 通過JsonResponse類返回json字串
19     elif req.method == 'PUT':
20         pass
21     elif req.method == 'DELETE':
22         pass
