def get_query_all(dic=None,values=None):
    res = oneModel.objects.filter(**dic).values(*values)
    return res

1. 多級搜尋: 將搜尋項以字典格式傳入filter,注意解包 **
2. 得到所需的列:將所需列以列表形式傳入values,得到一個字典列表[obj1,obj2,obj3]

實現下載功能:

obj = get_query_all(dic, header)
buf = BytesIO()     # from io import BytesIO
import openpyxl
appeal_wb = openpyxl.Workbook(encoding='utf-8',write_only=True)
ws = appeal_wb.create_sheet()
ws.append(list(header_dic.values()))
for row in obj:
    ws.append(list(row.values()))
appeal_wb.save(buf)
file = buf.getvalue()
response = HttpResponse(content_type='application/vnd.ms-excel')
response['Content-Disposition'] = 'attachment;filename=' + 'RebatePool' + '.xls'
response.write(file)
return response
