前端导出Excel和后台导出Excel表

import csv
from django.http import HttpResponse
from django.contrib.auth.models import User
def export_users_csv(request):
    response = HttpResponse(content_type='text/csv')
    response['Content-Disposition'] = 'attachment; filename="users.csv"'
    writer = csv.writer(response)
    writer.writerow(['Username', 'First name', 'Last name', 'Email address'])
    users = User.objects.all().values_list('username', 'first_name', 'last_name', 'email')
    for user in users:
        writer.writerow(user)
    return response

将数据导出到XLS文件

如果您确实需要导出到.xls文件，请使用这个方法。你将能够添加格式为粗体字体、字体大小、定义列大小等。

首先，安装xlwt模块。最简单的方法是使用pip。

pip install xlwt

import xlwt
from django.http import HttpResponse
from django.contrib.auth.models import User
def export_users_xls(request):
    response = HttpResponse(content_type='application/ms-excel')
    response['Content-Disposition'] = 'attachment; filename="users.xls"'
    wb = xlwt.Workbook(encoding='utf-8')
    ws = wb.add_sheet('Users')
    # Sheet header, first row
    row_num = 0
    font_style = xlwt.XFStyle()
    font_style.font.bold = True
    columns = ['Username', 'First name', 'Last name', 'Email address', ]
    for col_num in range(len(columns)):
        ws.write(row_num, col_num, columns[col_num], font_style)
    # Sheet body, remaining rows
    font_style = xlwt.XFStyle()
    rows = User.objects.all().values_list('username', 'first_name', 'last_name', 'email')
    for row in rows:
        row_num += 1
        for col_num in range(len(row)):
            ws.write(row_num, col_num, row[col_num], font_style)
    wb.save(response)
    return response

修改模板后导出Excel表

  response = HttpResponse(content_type='application/vnd.ms-excel')
    response['Content-Disposition'] = 'attachment;filename=统计报表.xlsx'.encode(encoding="utf-8")

    workbook = load_workbook('faultStatistics/统计报表模板.xlsx')
    workbook.guess_types = True  # 猜测格式类型
    ws = workbook.active

    # 修改项目名称
    project = TProject.objects.filter(id=project_id).first()
    ws['A1'] = project.project_name

    # 按设备名统计故障数
    devices = TDevice.objects.filter(project_id=project_id).values_list("name", flat=True)
    data_device_list = []
    for name in set(devices):
        device_ids = TDevice.objects.filter(name=name).values_list("id", flat=True)
        count = TAlarm.objects.filter(device_id__in=device_ids).count()
        data_device_list.append({"name": name, "num": count})

    for index, item in enumerate(data_device_list):
        ws['A' + str(index + 4)] = item.get("name")
        ws['B' + str(index + 4)] = item.get("num")

    # 按厂家统计故障数
    factorys = TDevice.objects.filter(project_id=project_id).values_list("factory", flat=True)
    data_factory_list = []
    for factory in set(factorys):
        device_ids = TDevice.objects.filter(factory=factory).values_list("id", flat=True)
        count = TAlarm.objects.filter(device_id__in=device_ids).count()
        data_factory_list.append({"factory": factory, "num": count})
    for index, item in enumerate(data_factory_list):
        ws['D' + str(index + 4)] = item.get("factory")
        ws['E' + str(index + 4)] = item.get("num")

    # 工程故障总数/已报修次数
    alarm_years = TAlarm.objects.filter(project_id=project_id).values_list("create_date", flat=True)
    alarm_years = set([date.year for date in alarm_years if date is not None])
    data_fault_by_year = []
    for year in list(alarm_years):
        fault_total_num = TAlarm.objects.filter(project_id=project_id).filter(create_date__year=str(year)).count()
        fault_repair_num = TAlarm.objects.filter(project_id=project_id).filter(create_date__year=str(year)).exclude(
            status="UNSOLVED").count()
        data_fault_by_year.append({'year': str(year), 'total_num': fault_total_num, 'repair_num': fault_repair_num})
    for index, item in enumerate(data_fault_by_year):
        ws['G' + str(index + 4)] = item.get("year")
        ws['H' + str(index + 4)] = item.get("total_num")
        ws['I' + str(index + 4)] = item.get("repair_num")

    # 当年设备故障比率
    fault_rate_list = TAlarm.objects.filter(project_id=project_id).values("alarm_type").annotate(
        count=Count('alarm_type'))
    fault_rate_list = fault_data_by_alarm_type(fault_rate_list)
    fault_total_num = sum([item.get("value") for item in fault_rate_list])
    for index, item in enumerate(fault_rate_list):
        ws['K' + str(index + 4)] = item.get("name")
        ws['L' + str(index + 4)] = item.get("value")
        ws['M' + str(index + 4)] = item.get("value") * 100 / fault_total_num

    # 写出到IO
    output = BytesIO()
    workbook.save(output)
    # 重新定位到开始
    output.seek(0)
    response.write(output.getvalue())
    return response
