Circumnavigating the Postgres ARRAYField inconvenience in DJANGO 1.9

Question

Here is the model field:

prices = ArrayField(models.DecimalField(max_digits=6, decimal_places=2), null=True)...

Values:

prices': [[Decimal('23.00'), Decimal('38.50')], [Decimal('11.06')], [Decimal('20.00')], [Decimal('3.95')], [Decimal('11.00')], [Decimal('1.77'), Decimal('31.34')], [Decimal('6.62'), Decimal('19.00')], [Decimal('20.60')].....]

My aim is to insert into the Postgres DB thusly:

models.DasModel.objects.create(
               somedate     = date,
               myprices     = prices,..)

I understand Postgres cannot accept such lists into an ArrayField but they must be of the form {val1, val2,...} The error I am getting is

DETAIL: "[" must introduce explicitly-specified array dimensions.

Is there an quick and easy way to do the conversion?

尝试使用-

prices = ArrayField(ArrayField(models.DecimalField(max_digits=6, decimal_places=2)), null=True)...
