how to get parent model object based on child model filter in django

To get the parent model object based on a child model filter in Django, you can follow these steps:

Step 1: Import the required models and modules in your Django view or function.

from django.shortcuts import get_object_or_404
from app.models import ParentModel, ChildModel

Step 2: Use the child model's filter method to get the desired child object(s).

child_objects = ChildModel.objects.filter(<filter_conditions>)

Step 3: Iterate over the child_objects to access the parent object(s) using the foreign key relationship.

parent_objects = []
for child in child_objects:
    parent_objects.append(child.parent)

Alternatively, you can use a list comprehension to achieve the same result.

parent_objects = [child.parent for child in child_objects]

Step 4: You now have the parent objects based on the child model filter. You can use them as needed in your code.

for parent in parent_objects:
    # Do something with the parent object

Remember to replace "ParentModel" and "ChildModel" with the actual names of your parent and child models, respectively. Also, make sure to define the foreign key relationship between the parent and child models in your Django models.
