Hello, when creating a new field and using the digits parameter to define a decimal precision, I get this error:

unknown parameter 'digits', if this is an actual parameter you may want to override the method _valid_field_parameter on the relevant model in order to allow it 

My code is:

energy_ceiling = fields.Monetary(string='Techo US$/MWh (MAX)', digits=dp.get_precision('cec_monetary'))

I added the decimal precision record with this code:

forcecreate="True" id="cec_values" model="decimal.precision">
    name="name">CEC Valores Contrato
    name="digits">4

I can see the record loaded on Odoo.

Please advice.
