Free Previews

My friends, I have something exciting (and completely unnecessary) in the works.

To pave the way for all the stuff I want to say about that, I've added previewing to my blog.

First, I added a preview field to BlogPost: 

preview = models.TextField(_('preview'), blank=True)

This required another evolution of the db: 

MUTATIONS = [
    AddField('BlogPost', 'preview', models.TextField, initial='')
]

Then I added some logic to the body outputting part of my blogpost item template: 

{% if preview and blogpost.preview %}
    {{ blogpost.preview|markdown }}
    <p><a href="{{ blogpost.get_absolute_url }}">More...</a></p>
{% else %}
    {{ blogpost.body|markdown }}
{% endif %}

Then I just had to set preview to True in all the blog listing views. Here's how the home view looks (the rest are similar: 

def home(request):
    return date_based.archive_index(
        request,
        BlogPost.objects.all(),
        date_field='pub_date',
        template_name='blog/home.html',
        template_object_name='blogpost_list',
        extra_context={'preview': True}
        )
