get data from two fields in module Sale and display it in a custom field in the same module

Question

I need to fetch data from two fields from sales module:
amount_total = fields .Monetary(string="Total", store=True, compute='_compute_amounts', tracking=4)  and
date_order = fields .Datetime()  Then translate the data to text into another module and display it
"on the fly"
in another custom made one (test). And it should be done in one custom module, no additional modules is allowed.
test = fields .Char(string="test", default=lambda x : random .randint(1, 10), states= readonly_fields_states )  T

Hi,
We will use compute method for setting the value to the field, At first we need to fetch the sale order that we want to get the amount_total and date order from, to do that we will use the 'search' method and specify the domain for the record,
Try this code in the custom module:
test = fields.Char( compute = 'compute_test' )
def  compute_test ( self ):
"""Enter your domain in place of 'your_domain' """
for rec in self:
record = rec.env[ 'sale.order' ].search([your_domain])
amount_total = rec
