Is it possible to insert a 'row' into a view composed of multiple tables with a common auto-increment primary key?

Question

I've been reading up more about views in MySQL (not being my strongpoint), but I'm now wondering if anyone has an example of how to insert a row into a view composed of more than one table, where there is a supertype and subtype relationship?

For example, the 'party model' hierarchy, showing roles of employer and staff:

      party
    _ _ | _ _
   |         |
employer   staff

The tables for which (simplified):

party                             employer               staff
--------------------------------  ---------------------  -----------------
party_ID INT auto_increment (PK)  party_ID INT (FK)      party_ID INT (FK)
party_name VARCHAR                tax_reference VARHCAR  job_title VARCHAR
etc...                            etc...                 etc...

I know I can create a view to deal with just the relationship concerned:

CREATE VIEW staff_view AS SELECT party.party_ID, etc... FROM party INNER JOIN staff

When I add a member of staff, I want to create a record in the party table, then reference the auto-increment party_ID in the staff table. I can't see how to perform an insert in one statement, something like:

INSERT INTO staff_view (party_name, job_title, etc...) VALUES ('John Doe', 'CEO', etc)

I know I can acheive this programatically, but I am hoping there's a way to do it directly in the database and maintain the referential integrity. How would you approach this issue?
