Any efficient way to avoiding two forloops in django - django

Question

Any better or efficient way to this in django
{% for list1item in list1 %}
{% for list2item in list2 %}
{% if forloop.counter == forloop.parentloop.counter %}
{{ list1item }} {{ list2item }}
{% endif %}
{% endfor %}
{% endfor %}
I want to do something like this, but not working.
{% for list1item in list1 %}
{% with forloop.counter as i %}
{{ list2.i }}
{% endwith %}
{% endfor %}
Updated! Actually here is the story!
this is my forms.py
from django import forms
from .models import MedicalRecords
class UpdateMedicalRecordForm(forms.ModelForm):
class Meta:
model = MedicalRecords
fields = ("title", "file", "doctor")
widgets = {
"title": forms.Textarea(attrs={"rows": "", "class": "form-control"}),
}
I want a list of each medicalrecord form with It's instance so I'm using [UpdateMedicalRecordForm(instance=x) for x in medicalrecords] to create form for each medicalrecord.
my view.py is as
...
medicalrecords = get_list_or_404(MedicalRecords,somefilterings..)
forms = [UpdateMedicalRecordForm(instance=x) for x in medicalrecords]
...
then in template to access each form of medical record I'm using
<form method="POST" enctype="" class="">
<div class="modal-body">
<div class="form-group">
{% csrf_token %}
{% for form in forms reversed %}
{% if forloop.counter == forloop.parentloop.counter %}
{{ form.as_p }}
{% endif %}
{% endfor %}
</div>
<div class="submit-section text-center">
<button type="submit" class="btn btn-primary submit-btn">Submit</button>
<button type="button" class="btn btn-secondary submit-btn" data-dismiss="modal">Cancel</button>
</div>
</div>
</form>

Actually you can create a custom template tag in order to make your solution working :
# templatetags/custom_tags.py
from django import template
register = template.Library()
#register.filter
def get_index(obj, index):
"""
Try to get value from a list object with an index given in parameter.
Return an empty string if index doesn't exist
"""
try:
return obj[index]
except IndexError:
return ""
Then in your template you can do :
{% load custom_tags %}
{% for list1item in list1 %}
{{ list2|get_index:forloop.counter }}
{% endfor %}
But after reading your update, I believe you can find something cleaner for your use case.
