I have something like:
{% for mother in mothers_list %}
{% for father in fathers_list %}
{% Child.objects.get(mother=mother, father=father) as child %}
child.name
Unfortunately, I can't call a function with parameters from the template, so this line
{% Child.objects.get(mother=mother, father=father) as child %}
wont work. Any ideas of how how can I get the Child object each time?
you can write a custom template tags for this and this will be like:
In your project/templatetags/custom_tags.py:
from django.template import Library
register = Library()
@register.filter
def mother_father(mother_obj, father_obj):
// Do your logic here
// return your result
In template you use template tags like:
{% load custom_tags %}
{% for mother in mothers_list %}
{% for father in fathers_list %}
{{ mother|mother_father:father }}
Read https://docs.djangoproject.com/en/dev/howto/custom-template-tags/ and write a custom tag.
You could do this processing in the view function.
In views.py:
children_list = []
for mother in mothers_list:
for father in fathers_list:
try:
child = Child.objects.get(mother=mother, father=father)
except Child.DoesNotExist:
child = None
children_list.append(child)
Then in your template:
{% for c in children_list %}
{{ c.name }}
