Cant pass data to Chart.js with Django

Question

Im using bootstrap template for my website and have problem to pass data from view in django to html to chart.js

I tried to pass data like any other variable but it didnt worked. I cant see data

I have 2 charts one (pie) with predefined data set and second (doughnut) i want to pass data from view, neither shows after render.

What do i do wrong?

View.py

        ctx = {
            "tournament": tournament,
            "pairing": pairing,
            "players_points": players_points,
            "army_points": army_points,
            "teamB": teamB,
            "form": form,
            "green": green,
            "yellow": yellow,
            "red": red,
            "green_p": green_p,

            "red_p": red_p,
            "total": total,
            # "chart_data": chart_data,
            "chart_data": json.dumps(chart_data),
        }
