Django admin后台上传excel，并保存数据到数据库

models.py

class ImportFile(models.Model):
    file = models.FileField(upload_to='media')

admin.py

from .models import ImportFile
@admin.register(ImportFile)
class ImportFileAdmin(admin.ModelAdmin):
    list_display = ('file', )
    
    # 重写save_model
    def save_model(self, request, obj, form, change):
        res = super(ImportFileAdmin, self).save_model(request, obj, form, change)
        import_user(self, request, obj, change)
        return res

appmul下新建utils.py 内容如下

from openpyxl import Workbook, load_workbook
import datetime
from birthapp import models


def import_user(self, request, obj, change):
    # 拿到上传文件的obj最相应逻辑处理，obj相当于 models.objects.表.get(id=id)
    print(obj.file.path)
    wb = load_workbook(filename=obj.file.path)
    E = wb.active
    print("E:", type(E))
    # ws = wb.get_sheet_names()
    # ws = wb.get_sheet_by_name(ws[0])
    # print("ws:", ws, type(ws))
    print("行数：", E.max_row)
    print("列数：", E.max_column)
    # a = str(E.cell(row=2, column=5).value)  # 将excel中 1行2列 对应的数据传给a
    # print(a)
    # 找到第五列的所有手机号
    for row in range(3, E.max_row+1):
        phone = E.cell(row=row, column=5).value
        if not phone:
            continue
        birth = E.cell(row=row, column=6).value
        if birth:
            birth_flag = 1
        else:
            birth = E.cell(row=row, column=7).value
            print("农历：", birth, type(birth))
            if birth:
                birth_flag = 2
            else:
                continue
        print("第n行数：", row, "手机号：", phone, "生日：", birth, "标记", birth_flag)
        try:
            month = birth.split("月")
            day = month[1].replace("日", '')
            birth = datetime.date(2021, int(month[0]), int(day))
            models.Employee.objects.filter(mobile=phone).update(birth=birth, birth_flag=birth_flag)
        except Exception as e:
            print("error:", e)
