Changes from parent to many childs

[Marenostrum81]

I have a parent that makes a few database queries.
In the parent template I add some child includes, for use the queries in some different ways (plot a graphic, calculations with pandas and make another table, etc)

Everything is working good, and doing this I only have to do a single query to the database, and not for every component.

But the problem is I cannot update the childs when the parent is updated.

I see is more normal to update the parent from the child in the docs, but I cannot figure how to do this updates when a change occurs in the parent.

What is the correct way to update more than one child when changes ocurrs in the parent?

In the table.py section of https://www.django-unicorn.com/docs/child-components/#multiple-children there is this code:

for child in self.children:
  if hasattr(child, "is_editing"):
      child.is_editing = False

Something similar to that is how I've handled changing a child from a parent.

Child components can sometimes be tricky to get working, but hopefully that is helpful!
