The first argument to IS_IN_DB can be either a DAL object (i.e., just "db") or a Set object (which is what you want). The second argument must be a field (either a field object or the name in 'tablename.fieldname' form) -- it cannot be a Query object, as you are using. So, you want:
IS_IN_DB(db(db.Organization.organizationPrimaryTypeID == 1), 'Organization.id') This is explained in the book <http://web2py.com/books/default/chapter/29/07/forms-and-validators#Database-validators> . You might also want to include db.Organization._format as the third argument, so the labels in the select element will be based on the "format" attribute of the Organization table. Regarding your other initial attempts: - If you are going to use a lambda function as a validator, not that it must take a Field object as its first argument and the value to be validated as its second argument, and it must return a tuple, with the (possibly transformed) value as the first element, and either None or an error message as the second. - If you put IS_IN_DB in a list, you won't get a dropdown in forms. To use additional validators with IS_IN_DB but still get the dropdown, instead of putting it in a list, pass the additional validators as its "_and" argument (also documented in the book).
