I want to define, and append to blocks defined in the base.html template.
Say I have the following template
<!DOCTYPE html>
<html>
<head>
<title>My Project</title>
{% block append_to_me %}{% endblock %}
</head>
<body>
{% block content %}{% endblock content %}
</body>
</html>
I would then use the following template for my views, my views render some wagtail components, and those components might want to use the append_to_me block.
This goes not only for the wagtail blocks, but also for plain django template tags
{% extends "base.html" %}
{% block content %}
<h2>Content for My App</h2>
<p>Stuff etc etc.</p>
{# I want it to not matter where I use this. #}
{% my_custom_tag %}
{% endblock content %}
Where {% my_custom_tag %} would do something like this:
@register.simple_tag(takes_context=True)
def my_custom_tag(context):
objects = Preload.objects.all()
for object in objects:
append_to_header_block(object.html)
Wagtail block example:
class MyBlock(blocks.StructBlock):
title = blocks.CharBlock()
content = blocks.RichTextBlock()
class Meta:
template = 'myapp/myblock.html'
myapp/myblock.html
{% add_to_header IMG "img/my-img.jpeg" %}
...
I also want to be able to keep the content of previous calls to the add_to_header function,
as to not overwrite the previous content.
I just cannot figure out how I would implement this, because there are a few issues:
- Order of evaluation, I am pretty sure the content of base.html gets rendered before any of the other templates.
- Maybe this can be fixed by somehow overwriting the
append_to_meblock from anywhere; and callingblock.superevery time? Somehow would be my question.
- Maybe this can be fixed by somehow overwriting the
- Wagtail blocks might not even know they are not used in base.html due to their versatility.
Any ideas as to how I would implement this? I am not even sure if this is possible, but I would love to hear your thoughts on this.
