templates block prepend and append

[Mateusz Harasymczuk]

I have recently fought with extending templates.

Plenty of my usecases are almost the same: append some html before or after admin templates blocks.

To do so, I have to take template, copy the contents and save modified file as a html in my templates dir.

What happens if django contrib.admin pages gets an update?

I have to take templates and do my job once again.

I suggest adding templatetag

- {% prepend "blockname" %}{% endprepend %}

- {% append "blockname" %}{% endappend %}

or "before/after" blocks

or even modification to extends

{% extends "admin/index.html" "after" "blockname" %}

What do you think?

{{ block.super }} sounds like what you want. If not, please let us know why.

This should solve my problems, therefore my question is no longer valid.

I missed that in the documentation.

Probably I should ask at django-users first.

Although

{% extends "admin/index.html" after "blockname" %}

would be a nice shorthand.

or 

{% from "admin/index.html" import "blockname" %}

to import only one block from a template file.

I liked his suggestion, I don't know if I'm using template tags correctly, but I'm writing a template tag {% load_comment comment_manager %} ,
"load_comment" renders a file "comments.html" and also needs a file "comment.js" and in any page that has comments, I have to add "comment.js" manually to my {% block js %}.
it was better if i could put something like this in my "comments.html" file

{% append_block js %}
< script src="..." ></script>
{% end_append_block %}
 
Best regards

Hi Jun,

I think this might do what you want:

{% block js %}{{ block.super }} <script src="..."></script> {% endblock %}

But, like the original poster said, please use django-users list for things like this.

Thanks,

Collin

I think it does not -- this, as he complained, needs to be put manually in
every page which uses his {% load_comment %} tag; IIUC, he's asking for a way
for his tag to do that for him.

I'm not sure that such a mechanism is feasible or even sensible within DTL,
but it's a valid issue for this list, unless I'm missing something.
