i would like to convert in my flask app an SQL query to an plotly pie chart
using pandas. this is my code :
def query_tickets_status() :
query_result = pd.read_sql ("""
SELECT COUNT(*)count_status, status
FROM tickets
GROUP BY status""", con = mydc_db)
return query_result
labels_statut = query_tickets_status['status']
values_statut = query_tickets_status['count_status']
fig = go.Figure(data=[go.Pie(labels=labels_statut, values=values_statut)])
graphSuppliers = json.dumps(fig, cls=plotly.utils.PlotlyJSONEncoder)
return render_template('admin/dashboard.html', graphSuppliers = graphSuppliers)
this is my template file.
<html>
<body>
<h1>Your Plotly Chart</h1>
<div id='chart' class='chart'></div>
</body>
<script src='https://cdn.plot.ly/plotly-latest.min.js'></script>
<script type='text/javascript'>
var graphs = {{graphSuppliers | safe}};
Plotly.plot('chart',graphs,{});
</script></html>
but I get this error :
TypeError: 'function' object is not subscriptable
