Description:

I'm trying to load a static image within an HTML() section of a crispy layout, using something like:

HTML("""
  <img src="{{ static('image.jpg') }}">
""")

Crispy is being rendered with Jinja2, using:

@pass_context
def crispy(context, form):
    return render_crispy_form(form, context=context)

This throws the following exception:

   File "/var/www/html/project/jinja2.py", line 20, in crispy
     return render_crispy_form(form, context=context)

     raise TemplateSyntaxError("Could not parse the remainder: '%s' "

Thanks so much!

As I understand it, crispy-forms is all based upon DTL, and it would be quite a large job to create Jinja2 versions of these templates as well.

I think the recommendation here would be to create a jinja2 version of the template packs, and that they could sit as their own series of packages.
