【问题描述】：

当我尝试运行时出现此错误

File "/home/normsoftware/WORK/JVB/healthtracker/quicklook/urls.py", line 39, in <module>
    url(r'^users/print$',views.export_users_xls(),name="Exceldata"),
TypeError: export_users_xls() missing 1 required positional argument: 'request'

views.py

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 = ['first', 'last',]

    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 = Registration.objects.all().values_list('first', 'last')
    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

所有行缩进都是正确的

urls.py

url(r'^users/print$',views.export_users_xls(),name="Exceldata"),

【问题讨论】：

去掉urls.py中views.export_users_xls()中的括号。

标签： django python-3.x django-templates django-views django-excel

【解决方案1】：

将您的网址更改为： url(r'^users/print$',views.export_users_xls ,name="Exceldata")

如您所见，我没有执行 export_users 函数（因此请删除括号），请参见以下示例： https://docs.djangoproject.com/en/2.0/topics/http/urls/#example
