Question

我正在使用熊猫ExcelWriter和openpyxl在Django项目中创建Excel。如何在项目目录中设置特定路径以保存创建的Excel？谢谢，谢谢。

from pandas import ExcelWriter
df_view = obj_master.get_employee()
writer = ExcelWriter('PythonExportt.xlsx')
df_view.to_excel(writer, 'Sheet1')
writer.save()

Answer 1

使用./path/to/file声明本地路径

更新

或者，您可以在settings.py中定义路径，然后将其作为

导入到任何django文件中。

Settings.py：

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

在Django中的某个地方：

from django.conf import settings
def write_to_excel(dataFrame, sheetName): 
writer = pd.ExcelWriter(settings.BASE_DIR, engine='xlsxwriter')
dataFrame.to_excel(writer, sheetName='Sheet1')
writer.save()

Answer 2

最好的方法可能是将Pandas Excel流写入内存流，然后将其包装到HTTP响应中：

from pandas import ExcelWriter

XLSX_MIME = 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'

def some_excelfile_view(request):
    response = HttpResponse(content_type=XLSX_MIME)
    response['Content-Disposition'] = 'attachment; filename="PythonExport.xlsx"'

    # obtain obj_master
    # ...
    writer = pd.ExcelWriter(response, engine='xlsxwriter')

    df_view = obj_master.get_employee()
    df_view.to_excel(writer, 'Sheet1')
    writer.save()
    return response

然后，您可以使用映射到此url的{{1}}。如果用户随后访问该URL，它将为Excel文件执行文件下载。

Answer 3

获取项目目录的路径，而不受任何约束。 settings.py在BASE_DIR中具有项目目录的值，您应该导入它并保存文件

from myproject.settings import BASE_DIR
from pandas import ExcelWriter
import os

save_path = os.path.join(BASE_DIR, 'backup')

df_view = obj_master.get_employee()
writer = ExcelWriter('{}/PythonExportt.xlsx'.format(save_path))
df_view.to_excel(writer, 'Sheet1')
writer.save()
