Reverse not found

[toneldaclan]

This code works well:

def detail(request, entity_group_id):

    entity_group = get_object_or_404(EntityGroup, pk=entity_group_id) # noqa

    entity_list = entity_group.members.order_by('name')

    context = {

        'entity_group': entity_group,

        'entity_list': entity_list,

    }

    return render(request, 'core/detail.html', context)

When I converted it to a Generic View, a Reverse not found error occured

class DetailView(generic.DetailView):

    model = EntityGroup

    template_name = 'core/detail.html'

    def get_context_data(self, **kwargs):

        context = super(DetailView, self).get_context_data(**kwargs)

        context['entity_group'] = EntityGroup

        context['entity_list'] = EntityGroup.members

        return context

This is mu models.py

class Entity(models.Model):

    is_person = models.BooleanField(default=True)

    person = models.ForeignKey(Person, on_delete=models.PROTECT, null=True) # noqa

    company = models.ForeignKey(Company, on_delete=models.PROTECT, null=True) # noqa

    name = models.CharField(max_length=30)

    def __str__(self):

        return self.name

    @property

    def title(self):

        return self.name

    class Meta:

        verbose_name_plural = 'entities'

class EntityGroup(models.Model):

    name = models.CharField(max_length=20)

    is_individual = models.BooleanField(default=True)

    members = models.ManyToManyField(Entity, through='Membership')

    def __str__(self):

        return self.name

    @property

    def title(self):

        return self.name

class Membership(models.Model):

    entity_group = models.ForeignKey(EntityGroup, on_delete=models.PROTECT, null=False) # noqa

    entity = models.ForeignKey(Entity, on_delete=models.PROTECT, null=False)

    def __str__(self):

        return self.entity_group.name + '-' + self.entity.name

    @property

    def title(self):

        return self.entity_group.name + '-' + self.entity.name

    class Meta:

        unique_together = ("entity", "entity_group")
