Jinja2 and Django-unicorn

[bschollnick]

Folks,

I'm trying to get Django-unicorn to play nicely with Jinja2 templates (via Jinja2 and Django-Jinja.

This isn't so crazy as it sounds... But requires a couple of tags to be added to the Jinja2 environment.

e.g.

`
from django.templatetags.static import static
from django.urls import reverse
from django_icons.templatetags.icons import icon_tag
from jinja2 import Environment
from django_unicorn.templatetags.unicorn import unicorn_scripts, unicorn

def environment(**options):
env = Environment(**options)
env.globals.update({
'static': static,
'url': reverse,
'icon':icon_tag,
'unicorn':unicorn,
'unicorn_scripts':unicorn_scripts,
})
return env
`

when used in a jinja2 template, e.g.

`

{{ unicorn }}

<script src="https://use.fontawesome.com/releases/v5.3.1/js/all.js"></script> <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script> <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery.lazy/1.7.9/jquery.lazy.min.js"></script> <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery.lazy/1.7.9/jquery.lazy.plugins.min.js"></script> <title>{% block title %} {{ gallery_name }} {% endblock %}</title> `

I'm getting an error stating that it requires parameters.

Request Method:	GET
http://nerv.local:8888/albums/-these/2010-10-10?page=1&sort=0
4.1.4
TypeError
unicorn() missing 2 required positional arguments: 'parser' and 'token'

Which makes sense due to the parameters in the function...

But according to the documentation, unicorn doesn't have any parameters?

---

4. Add {% unicorn_scripts %} into the Django HTML template and make sure there is a {% csrf_token %} in the template as well.

{% load unicorn %}

{% unicorn_scripts %} {% csrf_token %} -----------

So what am I missing here? Did I misunderstand something?

Hmm, this is not something I've ever tried to do. :)

To answer your question, parser and token arguments are used for the unicorn function because it's a custom templatetag that jumps through a bunch of hoops to parse the args, kwargs, render the component (similar to how the include templatetag works if I remember correctly), etc. That all happens in render. For more details on how this works, check out Writing the compilation function in the docs.

I look forward to seeing if this is possible and what you come up with!
