Introduction to Django Family Tree Development

Building a family tree web application with Django requires careful planning of data models, user relationships, and genealogy-specific features. This comprehensive tutorial will guide you through creating a professional genealogy platform.

Setting Up Your Django Family Tree Project

Start by creating a new Django project specifically designed for genealogy data management:

django-admin startproject family_tree_project
cd family_tree_project
python manage.py startapp genealogy

Essential Django Models for Family Trees

The foundation of any Django family tree application is a well-designed Person model with proper relationships:

class Person(models.Model):
    first_name = models.CharField(max_length=100)
    last_name = models.CharField(max_length=100)
    birth_date = models.DateField(null=True, blank=True)
    death_date = models.DateField(null=True, blank=True)
    gender = models.CharField(max_length=1, choices=[('M', 'Male'), ('F', 'Female')])
    father = models.ForeignKey('self', on_delete=models.SET_NULL, null=True, blank=True, related_name='children_as_father')
    mother = models.ForeignKey('self', on_delete=models.SET_NULL, null=True, blank=True, related_name='children_as_mother')
