Answer 1

in the views.py we can add this

def job_at_company(request, slug):
    results = Jobs.objects.filter(company__slug=slug)

    context = {'items':results}

    return render(request, 'jobs.html',context)

Answer 2

Suppose you pass id in the url . The id is the primary key of the company. You would have to modify your url to accept id like -

url(r'^jobs/(?P<slug>[\w-]+)/(?P<pk>[\d]+)$', views.job_at_company, name='job_at_company')

And modify your views.py -

def job_at_company(request, slug, pk):
    jobs_qs = Jobs.objects.filter(company__id=pk)
    return render(request, 'jobs.html', {'jobs': jobs_qs})

And use it in your html like -

{% for job in jobs %}
    {{job.title}}
{% endfor %}
