Question

I have two related models:

class Package(models.Model):
    package_name = models.CharField(max_length=64)
    ptype = models.CharField(max_length=16)

class Extra(models.Model):
    package = models.ForeignKey(Package, related_name='package')
    data = models.DecimalField(max_digits=8, decimal_places=2, blank=True, null=True)
    information = models.CharField(max_length=1024, blank=True)

view.py:

def show_package(request):
    list = get_list_or_404(Package, ptype='sometype')
    return render(request, 'table.html', {'list': list})

and template:

{% for row in list %}
<table class="provider_list">
 <tr>
     <td>{{ row.package_name}}</td>
     <td>{{ row.ptype }}</td>
</tr>
</table>
{% endfor %}

How can I add an additional table (from Extra model) next to the prelated table?

Like:

<table>
{% for extra_row in extra_list %}
<tr>
    <td>{{ extra_row.data }}</td>
    <td>{{ extra_row.information }}</td>
</tr>
{% endfor %}
</table>

Thanks.

try this:

{% for package in list %}
    <table class="provider_list">
        <tr>
             <td>{{ package.package_name}}</td>
             <td>{{ package.ptype }}</td>
             <td>
                <!-- fetch the related data -->
                <table>
                {% for extra in package.extra_set.all %}
                    <tr>
                        <td>{{ extra.data }}</td>
                        <td>{{ extra.information }}</td>
                    </tr>
                {% endfor %}
                </table>
             </td>
        </tr>
    </table>
{% endfor %}
