How to pass content block to catalog.irender

[stfnx]

Hi,

first of all I have to say that JinjaX is a really cool approach and I really like it!

I have a base.jinja template, which other templates extend ({% extends "base.jinja" %}). Classic approach, but its not possible to use the <Contextbar> syntax in a classic template. Instead I have to use {{ catalog.irender("Contextbar") }}, which works fine for several scenarios.

But now I need to pass content to the Contextbar component. I tried

{{ catalog.irender("Contextbar", _content=self.contextbar()) }}

which kind of works, but if the child template (that extends base.jinja) doesn't define the contextbar block I get an error: jinja2.exceptions.UndefinedError: 'jinja2.runtime.TemplateReference object' has no attribute 'contextbar'

My next guess was:

{% block contextbar %}{% endblock contextbar %}
{{ catalog.irender("Contextbar", _content=self.contextbar()) }}

But this renders the block twice: Once before the component and once inside the component.

Ideally I want to use the <Contextbar> syntax. Here its straightforward to pass content. But then I would need to turn my base.jinja template into a JinjaX component. Then I couldn't use {% extends "base.jinja" %} anymore and I really can't think of a workaround for this. How does a full JinjaX approach without classic templates look like?

Thanks!

And as always I find a solution literally the second after I submit this post...

{% if self.contextbar %}
  {{ catalog.irender("Contextbar", _content=self.contextbar()) }}
{% endif %}

But still, I'd prefer the <Contextbar> syntax.
