I'm trying to create a sequense the prefix of sequence based on another field named country_of_origin , but it doesn't work
The code:

    
    
        Item Sequence
        product.template.sequence
         
        5
        
    
    

python code:

class ProductTemplate(models.Model):

_inherit = 'product.template'country_of_origin=fields.Char(string="Origin Country")
automatic_item_number=fields.Char(string="Item Number")
@api.model
def create(self,vals_list):
        #vals_list['admission_code']=self.env['ir.sequence'].next_by_code('product.tempate.sequence')
vals_list['automatic_item_number']=self.env['ir.sequence'].next_by_code('product.template.sequence')
    result = super(ProductTemplate, self).create(vals_list)
    print(self.automatic_item_number)
    return result
