Hello everyone,

I have 2 invoice lines with different taxes.

Line 1: account.tax(1)

Line 2: account.tax(1, 2)

I need to compare two many2many fields (related to account.tax) and return the exact taxes on each record on the loop.

I am trying:

domain = [('my_many2many_field_ids', '=', 'invoice_line_tax_ids.ids')]
test_taxes = self.env['my_model'].search(domain, limit=1)

(Tried also with "=like" with no luck...)

The result is always the 2 records above.

I am expecting to have:

- If account.tax(1) on domain, returns only first record;

- If account.tax(1, 2) on domain, returns only second record;

Can anyone help me please?

Thank you in advance
