Re: Accessing a python function from a blog post stored in the db?

Won't this force my blog posts to all be the same. i.e. Text then a image scroller?
How would I handle the case where a blog post was Text, image scroller, text, image scroller?

It sounds like your implementation is a little skewed.
If a blog post is made of multiple resources (summary, body, multiple image collections, etc.) You should probably have a model or models with the appropriate fields/relationships.  That way your template can house all of the template language, and you build a single, user facing blog post from the elements in the blog post model(s).
This also gives you the benefit of making the various resources available in other ways (eg. Show all my image collections, share collections, etc) as well as change your layout in the future without having hard-coded template calls in your content.

Thanks. I look forward to trying this soon.

I feel like I may be trying to swim against the current with this. Is this a problem with the way that I have decided to implement my blog or are these workarounds typical for django applications?

Yes. You will need to write a custom template tag to parse the
contents of the object as a template, render it within the current
context and return the generated data.

Writing a custom template tag:

https://docs.djangoproject.com/en/1.6/howto/custom-template-tags/#writing-custom-template-tags

Rendering templates to string:

https://docs.djangoproject.com/en/1.6/ref/templates/api/#rendering-a-context

Your content.html would then look something like this, assuming you
called the custom tag 'render':

{% for each in entries %}
<p>{% render each.entry %}</p>
{% endfor %}

Beware the massive security holes if you allow users to generate
content that your site then renders as a template.

Cheers

Tom
