Answer 1

It would be better to use a ListView . You would need to tell Django what the relevant model for your view is, ie:

class HomePageView(ListView):
    model = Pricingservice
    template_name = 'pages/home.html'

And then in your template, you can use:

{% for pricingservice in pricingservice_list %}
{{ pricingservice.pricing }}
{% endfor %}

I am not sure exactly how your two models differ, but maybe it would be better to merge them?

Answer 2

Try this solution:

class HomePageView(ListView):
    model = Pricing
    template_name = 'pages/home.html'

And then try this template:

{% for pricing in object_list %}
    {{pricing.plans}}<br>
    {% for service in pricing.pricingservice_set.all %}
        {{ service.services }}<br>
    {% endfor %}
{% endfor %}

Please add some styling yourself. :)

Answer 3

try this

views.py

class HomePageView(TemplateView):
    template_name = 'pages/home.html'
    
    def get_context_data(self, **kwargs):
        context = super(HomePageView, self).get_context_data(**kwargs)
        context['Pricing'] = Pricing.objects.all()
        return context

class PricePageView(ListView):
    model = Pricingservice
    template_name = 'pages/home.html'

urls.py

path('', HomePageView.as_view(), name='home'),
path('price/', PricePageView.as_view(), name='price'),

template.html

{% for pricingservice in Pricingservice_list %}
                    <ul>
                        <li>{{ pricingservice }}</li>
                
                    </ul>
                    {% endfor %}

am not sure this will work but try this if that answer does not work for you
