问题
My code:
class SaleOrder(osv.Model):
_inherit = 'sale.order'
_columns = {
'xx_delivery_date': fields.date(string='Delivery date'),
'xx_payment_method': fields.many2one('xx.payment.method',
string='Payment method'),
'xx_insurance_type': fields.many2one('xx.insurance.type', string='Insurance')
}
def _amount_insurance(self, cr, uid, val1, context=None):
val = 0.0
insurance_chosen = self.pool.get('xx.insurance.type').browse(cr, uid, insurance_percentage.id,context=context)
val = val1*insurance_chosen/100
return val
class InsuranceType(osv.Model):
_name='xx.insurance.type'
_columns = {
'name' : fields.char(size=128, string = 'Name'),
'sale_ids': fields.one2many('sale.order', 'xx_insurance_type', string = 'Sale orders'),
'insurance_percentage' : fields.float('Insurance cost in %')
}
I am trying to get the float from the 'insurance_percentage' field and add this percentage to val1.
At the moment my code results in
'Global name insurance_percentage not defined,
So I have to somehow tell the function to take the variable from the InsuranceType class but I don't know how to do this.
回答1:
For many2one field, we need to first take id of that record and than browse that record with id and take desire value from that.
Try with this code:
def _amount_insurance(self, cr, uid, ids, val1, context=None):
val = 0.0
for insurance in self.browse(cr, uid, ids,context=context):
if insurance.xx_insurance_type:
val = (val1 * (insurance.xx_insurance_type.insurance_percentage/100))
return val
