I an new-ish to Django, and I ask this to hear from more experienced users
whether this would work at all, and whether it would be considered a good
or bad practice.
Goal: given an object and an integer index, retrieve the sub-object at that
index within the incoming object.
Method: Write a custom tag. Provide the tag with the larger object, and
the integer index. Return the sub-object at that index (or whatever
field(s) are needed).
Usage:
{% for i in metarange %} {% graphobject_get_by_index graphobject {{ i }}
%} {% endfor %}
In this particular case, there is an issue about whether the sub-object can
be null, for some definition of null. There are various ways to deal with
that.
Again, I am new-ish to Django. Is there a similar approach in which
'get_by_index' is a method on class Graphobject, such that this would work?
{% graphobject.get_by_index {{ i }} %}
Thanks for any explanation about these approaches.
