I don’t know how to specify the path to the function, more precisely speaking the class

class MovieDetailView(DetailView):
    model = Movie
    template_name = 'movie_detail.html'
    context_object_name = 'detail'
    pk_url_kwarg = 'movie_id'

urlpatterns = [
    path('index/', views.MovieListView.as_view()),
    path('movie_detail/<int:pk>', views.MovieDetailView.as_view(), name='detail')
AttributeError: Generic detail view MovieDetailView must be called with either an object pk or a slug in the URLconf.

{% extends ‘base.html’%}
{% block content %}

{% endblock content%}

class MovieDetailView(DetailView):
model = Movie
template_name = ‘movie_detail.html’
context_object_name = ‘detail’
pk_url_kwarg = ‘movie_pk’
there is a video preview in html, there is a link to the video when I view the code through the browser, but the video does not start

If I didn’t understand your question, it may help if you provided more details about exactly what you’re trying to do.

Side note: When posting code, templates, tracebacks, etc, enclose the code between lines of three backtick - ` characters. This means you’ll have a line of ```, then your code (or traceback or template or whatever) then another line of ```. (I’ve fixed your original post above.)

What is the name of the FileField within the Movie model that stores the movie? It’s that attribute on which you use the .url reference, which you appear to have.

Ahh… You have:

But your url is defined as:

The name for the kwarg in the class must match the name of the parameter in the url.
