I would like to check if the id of a model exists in another attribute of another table.
E.g.: I have inserted a new entry in '1st_model', which id is '1'. When I go and see the form view of this entry, a function must be able to check if there is a value '1' in the field 'example' of the table '2nd_model' (example=1 is True)..
Is it possible to write such a function?
