El contexto Django 1.11 TypeError debe ser un dict en lugar de un contexto

Question

Acaba de recibir el error de error de Sentry El TypeError context must be a dict rather than Context. en uno de mis formularios. Sé que tiene algo que ver con Django 1.11, pero no estoy seguro de qué cambiar para solucionarlo.

Línea ofensiva

message = get_template(''email_forms/direct_donation_form_email.html'').render(Context(ctx))

En Django 1.8+ , el método de render la plantilla toma un diccionario para el parámetro de context . El soporte para pasar una instancia de Context está en desuso , y da un error en Django 1.10+.

En su caso, solo use un dict regular en lugar de una instancia de Context :

message = get_template(''email_forms/direct_donation_form_email.html'').render(ctx)

Es posible que prefieras usar el render_to_string directo render_to_string :

from django.template.loader import render_to_string

message = render_to_string(''email_forms/direct_donation_form_email.html'', ctx)
