Question

I am creating an application to display articles. In my model, I have a TextField that will contain the content of the article.

Now I would like to be able to render another application within my article. Let say I have a poll application and I would like to display a poll in the middle of the article. How can I do that ?

I tried by putting a {% render_poll 42 %} within the post but, as expected, it just display that within the generated page.

Should I create some kind of tag (like let say [poll=42]) and parse it before displaying the rendered html page ? (I use the markdown library, maybe I could extend it.) How can I do that to stay in a nice “django friendly” way ? I want that, when in the admin panel, I can easily insert poll (or other apps) within an article.

You could compile the TextField string as a template. Ie.:

from django.db import models
from django.template import Template, Context


class YourModel(models.Model):
    body = models.TextField()

    def render_body(self, context=None):
        template = Template(self.body)
        context = context or {}
        context['object'] = self
        return template.render(Context(context))

Then in the actual template, you could use {{ your_model.render_body }} rather than {{ your_model.body }}.
