Snippet List
If you need to use some source to construct your form (maybe some database info or some user input), or you use the same fields with the same functionality in various forms and need to write the same piece of code for each of them, then you are looking in the right place. With this snippet you won't have those issues any more. :P
This snippet present a way to wean the fields from the form.
The code is made using crispy-forms, but the same idea can be applied without using it.
Best luck!

A simple macro system that makes it possible to reuse previously defined
blocks, optionally with a custom context, similar to the macro
functionality in Jinja.
It requires some workarounds/hacks because we cannot reach
all the data from inside the django template system that we need, but it
seems to work pretty well so far. It is, however, also pretty untested at this point, so use at your own risk.
Examples:
base.html:
<!--
This is mandatory if you want to use the repeat-tag in
a template. It should as placed as earily as possible.
See below for how to mix with template inheritance.
-->
{% enablemacros %}
<!-- Note that {{ param }} does not exist. -->
{% block foo %}
A standard django block that will be written to the output.
{% if param %}{{ param }}{% endif %}
{% endblock %}
{% macro bar %}
Pretty much the same thing as a django block (can even be
overridden via template inheritance), but it's content
will NOT be rendered per default. Please note that it
ends with ENDBLOCK!
{% if param %}{{ param }}{% endif %}
{% endblock %}
<!-- Render foo for the second time -->
{% repeat foo %}
<!-- Render foo bar the first time -->
{% repeat bar %}
<!-- Render both blocks again, and pass a parameter -->
{% repeat foo with "Hello World" as param %}
{% repeat bar with "Hello World" as param %}
{% macro form %}do stuff with: {{ form }}{% endblock %}
{% for form in all_forms %}
{% repeat display %} <!-- will have access to {{ form }}
{% endfor %}
extend.html:
<!--
{% extends %} requires that it be the first thing in a template,
and if it is, everything except for block tags is ignored, so
{% enablemacros %} won't work. Instead, use:
-->
{% extends_with_macros 'base.html' %}
{% block foo %}
Will override "foo" in base.html
{% endblock %}
{% block bar %}
Will override the macro block "bar" in base.html. Whether
this is defined as block or macro doesn't matter.
{% endblock %}
Todo:
* This (both tags used) results in infinite recursion:
{% extends_with_macros "somefile" %}{% enablemacros %}
