How to access an attribute of an object using a variable in django template?

Question

How can I access an attribute of an object using a variable? I have something like this:

{% for inscrito in inscritos %}
   {% for field in list_fields_inscrito %}
      {{inscrito.field}} //here is the problem
   {% endfor %}
{% endfor %}

For example Inscrito have: inscrito.id, inscrito.Name and inscrito.Adress and I only want to print inscrito.id and inscrito.Name because id and Name are in the list_fields_inscrito.

Does anybody know how do this?

You can write a template filter for that:

myapp/templatetags/myapp_tags.py

from django import template

register = template.Library()

@register.filter
def get_obj_attr(obj, attr):
    return getattr(obj, attr)

Then in template you can use it like this:

{% load myapp_tags %}

{% for inscrito in inscritos %}
   {% for field in list_fields_inscrito %}
      {{ inscrito|get_obj_attr:field }}
   {% endfor %}
{% endfor %}
