Reverse Query Through Django Template File - django

Question

models.py file
class Company(models.Model):
name = models.CharField(max_length=30)
def __str__(self):
return self.name
class Contact(models.Model):
first_name = models.CharField(max_length=20)
last_name = models.CharField(max_length=20)
company = models.ForeignKey(Company, on_delete=models.CASCADE)
def __str__(self):
return self.first_name
views.py file
class company_detail(DetailView):
def get(self, request, *args, **kwargs):
company = get_object_or_404(Company, pk=kwargs['pk'])
context = {'company': company}
return render(request, 'crm/company_detail.html', context)
company_detail.html file
{% extends 'base.html' %}
{% block content %}
<div id="container">
<ul>
<li>{{company.name}}</li>
</ul>
{% for company in object_list %}
{{ company.name }}
{% for Contact in company.contact_set.all %}
{{Contact.first_name}}
{% empty %}
<!-- no entries -->
{% endfor %}
{% endfor %}
</div>
{% endblock content %}
I'm trying to get the Contacts who are under that company to show up on the company_detail.html page. How do I reverse query it properly to show all Contacts under that company?
Thanks in advance

Answer 1

There is no object_list in your DetailView's context, only the object. You need to remove the for loop over object_list in the template
{% for contact in company.contact_set.all %}
{{ contact.first_name }}
{% empty %}
<!-- no entries -->
{% endfor %}
