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

Thanks. I believe this is what I am looking for. However I am still running into an issue w/ the fact that I am pulling my blog entries from the db. This is causing the template to interpret the {% image_slider %} as a string.

From view.py:
def blog(request):
    entries = Project.objects.filter(destination="blog").order_by('-creation_date')
    return render(request, 'content.html', {"entries": entries,
                                               "page_title": "Blog",
                                               "description": "Blog"})

And in content.html:
{% for each in entries %}
<p>{{ each.entry }}</p>
{% endfor %}

And a blog entry:
Hello! Check out this collection of images. {% image_slider %} And this collection! {% image_slider %}


I don't want to hard code the inclusion tag in the content.html. Instead I want to call it from the blog post. Is this possible?

This sounds like a good fit for an inclusion tag. Since you need a bit of markup around the images for the slider functionality, it'd be nice to keep that markup in a separate template so you could use the image slider in multiple places like, say, a post detail page as well as a dashboard. Then, anytime you wanted to create image slider, in your template you could simply do something like:

{% load image_extras %}

...

{% image_slider post.image_set %}

...

Hi. I am looking for some advice on the best way to approach the following:

I am pulling my blog posts out of my db. Inside of the posts I want to use an image scroller ( http://cssdeck.com/labs/css3-image-slider ), but I don't want to write all of the boilerplate surrounding each image every time.

The idea I have is a template filter.... but that just seems wrong. What's the proper way to handle this?

Ideally, I would just add some bit in my post like css_slider({loc: loc_pic_1, desc: "blah blah"}, {loc: loc_pic_1, desc: "blah"}...)
