We need to provide a way to render each type of content. Edit the models.py file of the courses application and add the following render() method to the ItemBase model:
from django.template.loader import render_to_stringfrom django.utils.safestring import mark_safeclass ItemBase(models.Model): # ... def render(self): return render_to_string('courses/content/{}.html'.format( self._meta.model_name), {'item': self})
This method uses the render_to_string() function for rendering a template and returning the rendered content as a string. Each kind of content is rendered using a template named after the content model. We use self._meta.model_name to generate the appropriate template name for each content model ...
