AttributeError: 'WSGIRequest' object has no attribute 'is_ajax' in Django 4 + highcharts

I'm trying to configure the display of graphs in Django using highcharts and I encounter this error:

AttributeError: 'WSGIRequest' object has no attribute 'is_ajax'

Code:

views.py

import random

from django.shortcuts import render
from highcharts.views import HighChartsBarView


class BarView(HighChartsBarView):
    title = 'Example Bar Chart'
    subtitle = 'my subtitle'
    categories = ['Orange', 'Bananas', 'Apples']
    chart_type = ''
    chart = {'zoomType': 'xy'}
    tooltip = {'shared': 'true'}
    legend = {'layout': 'horizontal', 'align': 'left',
              'floating': 'true', 'verticalAlign': 'top',
              'y': -10, 'borderColor': '#e3e3e3'}

    @property
    def series(self):
        result = []
        for name in ('Joe', 'Jack', 'William', 'Averell'):
            data = []

        for x in range(len(self.categories)):
            data.append(random.randint(0, 10))
        result.append({'name': name, "data": data})
        return result

index.html

$('#container').highcharts(data);
});
});
</script>
</head>
<body>
<div id="container" style="height: 300px"></div>
</body>
</html>

I have no idea how to fix it

Solution

  • Django-braces does not support officially django4+ : https://pypi.org/project/django-braces/

    Ths issue has already been fixed in the github, but not yet released. https://github.com/brack3t/django-braces/issues/288

    You can install the github version with pip :

    pip install git+https://github.com/brack3t/django-braces.git

    I hope there is just this compatibility problem with django 4+ and it will be work
