• Django 批量导入文件


    1. 按照xlrd软件

    pip3 install xlrd
    

    2. POST提交文件获取数据

    方法一:写入硬盘,xlrd读取xlsx文件获取文件数据

        def batch_view(self,request):
            if request.method=="GET":
                return render(request,'batch_view.html')
            else:
                from django.core.files.uploadedfile import InMemoryUploadedFile
                file_obj = request.FILES.get('xsfile')
    
                with open('customers.xlsx', mode='wb') as f:
                    for chunk in file_obj:
                        f.write(chunk)
    
                import xlrd
                workbook = xlrd.open_workbook('customers.xlsx')
                sheet = workbook.sheet_by_index(0)
                maps = {
                    0: 'qq',
                    1: 'name',
                    2: 'gender',
                    3: 'education',
                    4: 'graduation_school',
                }
                for index in range(1,sheet.nrows):
                    row = sheet.row(index)
                    # {'name':"吧唧",'qq':9898}
                    row_dict = {}
                    for i in range(len(maps)):
                        key = maps[i]
                        cell = row[i]
                        row_dict[key] = cell.value
                    print(row_dict)
                    # 自动获取ID
                    # 录入客户表
                    # 录入客户分配表
    
                return HttpResponse('上传成功')

    方法二:不写入硬盘,写入内存,xlrd从内存中读取数据

        def batch_view(self,request):
            if request.method=="GET":
                return render(request,'batch_view.html')
            else:
                from django.core.files.uploadedfile import InMemoryUploadedFile
                file_obj = request.FILES.get('xsfile')
    
                from io import BytesIO
                f = BytesIO()
            
                for chunk in file_obj:
                    f.write(chunk)
                import xlrd
    
                workbook = xlrd.open_workbook(file_contents=f.getvalue())
                # getvalue()方法用于获得写入后的str。
                sheet = workbook.sheet_by_index(0)
                maps = {
                    0: 'qq',
                    1: 'name',
                    2: 'gender',
                    3: 'education',
                    4: 'graduation_school',
                }
                for index in range(1,sheet.nrows):
                    row = sheet.row(index)
    
                    row_dict = {}
                    for i in range(len(maps)):
                        key = maps[i]
                        cell = row[i]
                        row_dict[key] = cell.value
                    print(row_dict)
                #     # 自动获取ID
                #     # 录入客户表
                #     # 录入客户分配表
    
                return HttpResponse('上传成功')    

    打印数据:

    1 {'qq': 6515616.0, 'name': '内瑟斯', 'gender': '', 'education': '', 'graduation_school': ''}
    2 {'qq': 6515623.0, 'name': '武器大师', 'gender': '', 'education': '', 'graduation_school': ''}
    3 {'qq': 24674335.0, 'name': '迦娜', 'gender': '', 'education': '', 'graduation_school': ''}

    3. xlsx文件测试数据

        def batch_view(self,request):
            if request.method=="GET":
                return render(request,'batch_view.html')
            else:
                from django.core.files.uploadedfile import InMemoryUploadedFile
                file_obj = request.FILES.get('xsfile')
    
                # with open('customers.xlsx', mode='wb') as f:
                #     for chunk in file_obj:
                #         f.write(chunk)
                #
                from io import BytesIO
                f = BytesIO()
                for chunk in file_obj:
                    f.write(chunk)
                import xlrd
    
                workbook = xlrd.open_workbook(file_contents=f.getvalue())
                sheet = workbook.sheet_by_index(0)
                maps = {

                    sale_id = AutoSale.get_sale_id()
                    if not sale_id:
                        return HttpResponse("没有客户顾问无法分配")
                    row = sheet.row(index)  # 这是通过行数获取行的内容
                    dict_obj = {}  # 字典
    
                    row_dict = {}
                    for i in range(len(maps)):  # 这是获取列的数量
                        key = maps[i]       # 这是键
                        cell = row[i]       # 这是获取空格的对象
                        row_dict[key] = cell.value
                    print(row_dict)
                    try:
                        with transaction.atomic():
                            dict_obj['consultant_id'] = int(sale_id.decode('utf-8'))
                            ctime = datetime.datetime.now().date()
                            course_list = []
                            course_list.extend(dict_obj.pop('course').split(','))
                            print('course_list', course_list)
                            obj = models.Customer.objects.create(**dict_obj)

                            print('走到这里没')

                    except Exception as e:

                        AutoSale.rollback(sale_id)
                    message.send_message('自动发送', '很,兴奋代码自动发送邮件,', 'xxxx@qq.com', '大毛')
    
                return HttpResponse('上传成功')
