前台提交查询条件,下载符合条件的EXCEL数据文件,后端视图中使用 xlwt 库来返回,如:
objs = Units.objects.all() # 创建 Workbook 时,如果需要写入中文,请使用 utf-8 编码,默认是 unicode 编码。 wb = xlwt.Workbook(encoding=‘utf-8‘) ws = wb.add_sheet(‘配件价格‘) ws.write(0, 0, ‘配件编号‘) ws.write(0, 1, ‘配件名称‘) ws.write(0, 2, ‘配件价格‘) ws.write(0, 3, ‘商场‘) excel_row = 1 for obj in objs: ws.write(excel_row, 0, obj.unitid) ws.write(excel_row, 1, obj.unitname) ws.write(excel_row, 2, obj.price) ws.write(excel_row, 3, obj.marketid) excel_row = excel_row + 1 # ------ 开始:这段代码可以用下面注释段替代,都是本应保存为文件格式的改成保存为数据流,以便返回前端下载 response = HttpResponse(content_type=‘application/vnd.ms-excel‘) response[‘Content-Disposition‘] = ‘attachment; filename=example.xls‘ wb.save(response) return response # ------ 结束 """ sio = StringIO.StringIO() wb.save(sio) response = HttpResponse(sio.getvalue(),content_type=‘application/vnd.ms-excel‘) response[‘Content-Disposition‘] = ‘attachment; filename=test.xls‘ return response """
