One day you don't know what to do anymore. The future is so unpredictable. Too much choices. You must make the decission.

Yes, the pain is real. The fear is real. You want to run away from it. Why should you suffer from those horrible feelings? You can find other thing to do, the "easier" things.

But don't.

Because each time you let them scare you aways, you learned nothing. You are not improved. You are not lived.

   title = models.CharField(max_length=255)

class Child(models.Model):
   parent = models.ForeignKey(Parent, on_delete=models.CASCADE, related_name="children")
   content = models.TextField(null=True, blank=True)

For example, we want to search keyword in childs content, and we want to do it quick! You can do like this, but that not quick enough for me. Maybe because I have too damn much data. But there are other way. First we need to add this line to settings.py

settings = [
    # ...
    "django.contrib.postgres …
