Python Django错误：NoReverseMatch_Python_Django

Python Django错误：NoReverseMatch

python django

Python Django错误：NoReverseMatch,python,django,Python,Django,我正在使用Django 1.10和python 3.4 精确的误差是 NoReverseMatch at /movies/movie/Twilight/ Reverse for 'movie-details' with arguments '(8,)' and keyword arguments '{}' not found. 1 pattern(s) tried: ['movies/movie/(?P<movie_id>\\d+)|(?P<movie_name>[a-z

我正在使用Django 1.10和python 3.4

精确的误差是

NoReverseMatch at /movies/movie/Twilight/
Reverse for 'movie-details' with arguments '(8,)' and keyword arguments '{}' not found. 1 pattern(s) tried: ['movies/movie/(?P<movie_id>\\d+)|(?P<movie_name>[a-zA-Z\\ ]+)/$']

这是指moviesrating/views.py中的函数view\u movie：

url/movies/movie/…的用途。。。如果要显示通过名称或id找到的电影，则特定的url模式来自此需求

关键是错误显示，即使没有找到反向匹配，它也会找到正确的url模式，因此我认为该模式不匹配。然后我尝试将行更改为：

{% url 'moviesrating:movie-details' movie.id %}
{% url 'moviesrating:movie-details' movie_id=movie.id movie_name=None %}
{% url 'moviesrating:movie-details' movie.id None %}
{% url 'moviesrating.views.view_movie' movie.id %}
{% url 'moviesrating.views.view_movie' movie_id=movie.id %}
{% url 'moviesrating.views.view_movie' movie_id=movie.id movie_name=None %}

但没有一个成功

在浏览器中查看链接（例如。http://localhost:8081/movies/movie/8)工作正常，所以不是那个页面导致问题

在这一点上，我真的无法理解这个问题，我已经按照中解释的段落阅读了很多已经提出的问题，但没有一个解决了我的问题

如果有什么不清楚或更多的信息是需要的，请让我知道，我会编辑后。谢谢

以下是错误的完整堆栈跟踪：
