OpenERP 7 : How can I make conditions for a field's default value?

问题

This is the second step of my question about setting a default date in create form, I move it here to clarify the two questions :

My mission also consisted in setting the requested_date field to Monday if it was initially set on Saturday or Sunday with the operation, so I made conditions in _defaults with the "isoweekday" method of Date, but it seems that _defaults doesn't support conditions :

_defaults = {
    'requested_date': (date.today() + timedelta(days=28)).strftime(DEFAULT_SERVER_DATE_FORMAT),
    if requested_date.isoweekday = 6
        'requested_date': (date.today() + timedelta(days=30)).strftime(DEFAULT_SERVER_DATE_FORMAT),
    if requested_date.isoweekday = 7
        'requested_date': (date.today() + timedelta(days=29)).strftime(DEFAULT_SERVER_DATE_FORMAT),
}

The computer terminal tells me that the syntax is invalid where I use "if", it is the first time I use conditions so maybe I just didn't write them like I have to.

This is the complete message I get :

For those who want to know, for the second part of my question (avoiding requested_date to be in week-end), I have written this function and it seems working (at least it still shows the date of 28 days after the creation), I don't have the means to test it but at least I don't have errors when I update the database with this or when I try to create the form where this field is :

def _set_requested_date(self, cr, uid, ids, context=None):
    requested_date = (date.today() + timedelta(days=28)).strftime(DEFAULT_SERVER_DATE_FORMAT),
    day = date.today()
    if day.isoweekday() == 6:
        requested_date = (date.today() + timedelta(days=30)).strftime(DEFAULT_SERVER_DATE_FORMAT),
    if day.isoweekday() == 7:
        requested_date = (date.today() + timedelta(days=29)).strftime(DEFAULT_SERVER_DATE_FORMAT),
    return requested_date

_defaults = {
    'requested_date': _set_requested_date,
}

Thanks to amccormack and no coder for their help !
