updating child components via a parent method

[jacksund]

Branching from #662

I have a question about going one step beyond your example in the docs -- Can force_render be applied to a list of children components? I'm struggling to get this to work as expected. For example say I add the following method & html to the table component:

# method added to TableView

def begin_edit_all(self):
    for child in self.children:
        if hasattr(child, "is_editing"):
            print("child set to editting")
            child.is_editing = True
            # child.force_render = True  # doesn't trigger refresh
    # self.force_render = True # doesn't trigger refresh

<button unicorn:click="begin_edit_all"
        type="button">
    Edit All
</button>

My attempts to force_render child components fail. And as a more complex example, using filter + begin_edit_all applies to all books rather than those that have been filtered:

Here are the files for this example:
mysite_example3.zip

A more realistic example of this would involve a table where you want to apply a status to all child components. For example, we could have a list of tasks that are filtered down and then you apply a set_status_complete to these filters items - that updates the table + status column.

Hi,

I can confirm that I am also witnessing the behaviour you've described.

I would also highlight an even simpler case taken from the example in the documentation. It seems that setting the value of children from the parent doesn't produce the desired effect:

    def load_table(self):
        self.books = Book.objects.all()

        for child in self.children:
            if hasattr(child, "is_editing"):
                child.is_editing = True # This is not having any effect whatsoever
