How Can I Filter A Query By A Foreign Key?

I'm trying to get a list of 'Peliculas' filtered by their 'Director' in my DirectorDetailView I can't find the correct syntax to do this. Django Version: 2.1.4 #MODEL DIRECTOR cl

Solution 1:

You don't need to do this in the view at all; you do it in the template.

{{ director.nombre }}
{% for pelicula in director.pelicula_set.all %}
  {{ pelicula.titulo }}
  {{ pelicula.sinopsis }} # etc
{% endfor %}

You can delete the get_context_data method completely.
