How to show value from currency in account_invoice?

Question

I try to put the value from currency "rate" to my account_invoice rows.
my field looks like this:

show_rate = fields.Char(related="res_currency.rate", store=True)

this gives me everytime an error with res_currency.
I want to see the "rate" field in my account_invoice rows. How can I manage that?

thank you

It's not fair to use related field here. Related field will write back the value to the currency table.
If you only need to see the value, you could use a functional field.
@api.one
@api.depends('currency_id', 'currency_id.rate')
def _compute_amount(self):
self.currency_rate = self.currency_id.rate
currency_rate = fields.Float('Currency Rate', compute='_currency_rate', store=True)
