excel 使用 Django xlwt 导出时出错

Question

我正在尝试使用 xlwt 库将信息从我的 Web 应用程序导出到 Excel 文件，但 urls.py

中出现以下错误

TypeError: export_excel_av_items() missing 1 required positional argument: 'request'

models.py:

class Stock(models.Model):
    id = models.AutoField(primary_key=True)
    name = models.CharField(max_length=30, unique=True)
    quantity = models.IntegerField(default=1)
    is_deleted = models.BooleanField(default=False)

    def __str__(self):
        return self.name

views.py:

def export_excel_av_items(request):
    response = HttpResponse(content_type='application/ms-excel')
    response['Content-Disposition'] = 'attachment; filename="available-items.xls"'
    wb = xlwt.Workbook(encoding='utf-8')
    ws = wb.add_sheet('Available Items')
    row_num = 0
    font_style = xlwt.XFStyle()
    font_style.font.bold = True

    columns= ['Name', 'Qty']

    for col_num in range(len(columns)):
        ws.write(row_num, col_num, columns[col_num], font_style)

    font_style = xlwt.XFStyle()

    rows = Stock.objects.all().values_list(
        'name', 'quantity')

    for row in rows:
        row_num += 1

        for col_num in range(len(row)):
            ws.write(row_num, col_num, str(row[col_num]), font_style)
    wb.save(response)

    return response

urls.py:

path('', views.StockListView.as_view(), name='inventory'),
path('new', views.StockCreateView.as_view(), name='new-stock'),
path('stock/<pk>/edit', views.StockUpdateView.as_view(), name='edit-stock'),
path('stock/<pk>/delete', views.StockDeleteView.as_view(), name='delete-stock'),
path('inventory/export-excel', views.export_excel_av_items(), name='export-excel'),

Answer 1

在 URL 中，你指向函数，你不调用它，所以下面一行

path('inventory/export-excel', views.export_excel_av_items(), name='export-excel'),

应

path('inventory/export-excel', views.export_excel_av_items, name='export-excel'),
