Django template with multiple models

Question

I have a template from which I need to render information from multiple models. My models.py look something like this:

# models.py
from django.db import models

class foo(models.Model):
    ''' Foo content '''

class bar(models.Model):
    ''' Bar content '''

I also have a file views.py, from which I wrote according to this Django documentation and the answer given here, and looks something like this:

# views.py
from django.views.generic import ListView
from app.models import *

class MyView(ListView):
    context_object_name = 'name'
    template_name = 'page/path.html'
    queryset = foo.objects.all()

    def get_context_data(self, **kwargs):
        context = super(MyView, self).get_context_data(**kwargs)
        context['bar'] = bar.objects.all()

        return context

and my urlpatterns on urls.py have the following object:

url(r'^path$',views.MyView.as_view(), name = 'name'),

My question is, on the template page/path.html how can I reference the objects and the object properties from foo and bar to display them in my page?

To access foos from your template, you have to include it in the context:

# views.py
from django.views.generic import ListView
from app.models import *
class MyView(ListView):
    context_object_name = 'name'
    template_name = 'page/path.html'
    queryset = foo.objects.all()

    def get_context_data(self, **kwargs):
        context = super(MyView, self).get_context_data(**kwargs)
        context['bars'] = bar.objects.all()
        context['foos'] = self.queryset
        return context

Now in your template you can access the value by referencing the key that you used when creating the context dictionary in get_context_data:

<html>
<head>
    <title>My pathpage!</title>
</head>
<body>
    <h1>Foos!</h1>
    <ul>
{% for foo in foos %}
    <li>{{ foo.property1 }}</li>
{% endfor %}
    </ul>

    <h1>Bars!</h1>
    <ul>
{% for bar in bars %}
    <li>{{ bar.property1 }}</li>
{% endfor %}
    </ul>
</body>
</html>

For the most simple cases, just use the common django templating language constructions, forloop-tag and {{}} variable notation:

{% for b in bar %}   # should be called 'bars' in the context, really
  {{ b }}            # will render str(b)
  {{ b.id }}         # properties, fields
  {{ b.get_stuff }}  # callables without parentheses
{% endfor %}

See the template language docs for more.
