Question

Я получаю:

django .urls.exceptions.NoReverseMatch: Реверс для 'company_delete' с аргументами '(' ',)' не найден. Попробован 1 шаблон (ов): ['company / (? P \ d +) / delete / $']

и в моей консоли он показывает:

- Не удалось загрузить ресурс: сервер ответил с состоянием 500 (Внутренняя ошибка сервера)

Мой views.py

def company_delete(request,pk):
    data = dict()
    company = get_object_or_404(Company,pk=pk)
    if request.method == "POST":
        company.delete()
        data['form_is_valid'] = True
        companies = Company.objects.all()
        data['company_list'] = render_to_string('company_list_2.html',{'companies': companies})
    else:
        context = {'company': company}
        data['html_form'] = render_to_string('company_delete.html',context,request=request)

    return JsonResponse(data)

мой urls.py

urlpatterns = [
    url(r'^company/$', views.company_list, name='company_list'),

Как говорят @ Иван Старостин просто поместите company.pk экземпляр c.pk в свой URL-адрес

<form method="post" data-url="{% url 'company_delete' company.pk %}" class="delete-form">
    ...
</form>
