我想使用 line profiler 来分析我的 django 项目以显示代码性能的分析。

我正在关注这些链接：

1. http://djangotricks.blogspot.in/2015/01/performance-bottlenecks-in-django-views.html

2. https://github.com/dcramer/django-devserver

但这对我不起作用。我收到有关开发服务器的错误，如下所示：

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/.virtualenvs/test/lib/python3.4/site-packages/django/core/management/__init__.py", line 350, in execute_from_command_line
    utility.execute()
  File "/.virtualenvs/test/lib/python3.4/site-packages/django/core/management/__init__.py", line 342, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)
  File "/.virtualenvs/test/lib/python3.4/site-packages/django/core/management/__init__.py", line 195, in fetch_command
    klass = load_command_class(app_name, subcommand)

我有一个名为的模型Container，其中包含字段received和name。我用来django-filter过滤这些字段。过滤后得到结果：

<list.filters.AdvancedSearchListFilter object at 0x7f68cd698828>

这是我的filter课程：

class AdvancedSearchListFilter(django_filters.FilterSet):

    field-1 = django_filters.DateFromToRangeFilter(label='Received Date Range')

    class Meta:
        model = Container
        fields = ['field-1', 'field-2']

如何获得过滤后的结果？

我正在使用Django过滤器通过在我的应用程序中给出日期范围进行搜索.

class AdvancedSearchListFilter(django_filters.FilterSet):
    received = django_filters.DateFromToRangeFilter(label='Received Date Range')

    class Meta:
        model = Container
        fields = ['received']

那么这个过滤器将创建我正在搜索To和From date range.SO的位置,因为我想放置一个占位符来显示日期格式,如'yyyy/mm/dd'.我怎样才能做到这一点？
