How to keep Django from escaping HTML in ModelAdmin

I have this class to configure django.contrib.admin for my Stream model.

class StreamAdmin(admin.ModelAdmin):
    def stream_title(instance):
        return instance.info.title

    def network_name(instance):
        return '<img src="%s" />' % instance.network.image_url

    fieldsets = (
        (None, {
            'fields' : ('name', 'network', 'score', 'custom_url')
        }),

    )

    list_display = ('name', stream_title, network_name, 'online', 'score')

    ordering = ('name', 'score')

The network_name function returns HTML, but it's escaped. How can I stop that?

Use allow_tags.

def network_name(instance):
    return '<img src="%s" />' % instance.network.image_url
network_name.allow_tags = True

You can use mark_safe:

from django.utils.safestring import mark_safe

class StreamAdmin(admin.ModelAdmin):
    ...

    def network_name(instance):
        return mark_safe('<img src="%s" />' % instance.network.image_url)

    ...

Try using safe filter at the template or even autoescape.

Using the autoescape tag you can set up a block like this:

{% autoescape on %}
    {{ model.network_name }}
{% endautoescape %}

<!-- or either -->
{{ model.network_name|safe }}
