Django 1.11: JSONField loaded as string during migration's RunPython

[hector...@unholster.com]

Hello,

We are moving to Django 1.11, but we have some models with JSONField fields, which are being used on some custom migration functions (called with RunPython). We're getting the following kind of errors:

    _ForecastType = apps.get_model('forecast', 'forecasttype')
    for forecast_type in _ForecastType.objects.all():
>     hours = forecast_type.params['reception_hours']
E     TypeError: string indices must be integers

so Django is not properly loading the field during the migration. What should we do to fix it?

Thanks very much for any help,
Hector.
