[web2py] start date to end date and verifying form

[Andrew Evans]

Hello I am having a seemingly difficult time with this :-)

and I am hoping some one can aid in solving this :-)

I am trying to make an item reserved from start-date to end-date any ideas 
*cheers here is my code

This my latest attempt googled and found this function

import datetime

def daterange( start_date, end_date ):
    if start_date <= end_date:
        for n in range((end_date - start_date).days + 1):
            yield start_date + datetime.timedelta(n)
    else:
        for n in range((start_date - end_date).days + 1):
            yield start_date - datetime.timedelta(n)

then in my web2py code I have

@auth.requires(auth.has_membership('second_year') or 
auth.has_membership('admin'))
def second_year_checkout():
    check_id = request.args(0)
    check = db(db.product.id == check_id).select()
    project_date = db(db.checkout.id>0).select()
    for valid in check:
        db.checkout.product.default=valid.id
        form = SQLFORM(db.checkout)
        if form.process().accepted:
            for project in project_date:
                start = project.date_in
                end = project.date_out
                for date in daterange(start, end):
                    if date:                    
                        session.flash = 'form accepted'
                        return dict(redirect(URL('default', 'next')))
                    else:
                        return dict(redirect(URL('error','availability')))
        elif form.errors:
            response.flash = 'form has errors'
        else:
            response.flash = 'please fill the form' 
            return dict(form=form)

*cheers and ty

Andrew
