Hola Vijay, agradezco tu respuesta,
Tienes razon, los campos los puse en None porque el erro me lo genera el
campo de articulo=articulo_data
Articulo_Consolidacion.objects.create(*articulo=articulo_data, *tag=taglist,
tono=array_tono, tema__id= temalist )
Aun no entiendo bien como funciona los set, te agradecería si me regalaras
un ejemplo.
Adicional no se si es correcto o se puede guardar un array o lista al
momento de hacer el save, en el caso de taglis y temalist.
Agradezco mucho tu ayuda.
