I am building a function to generate a docx report when a sales order is created. So far, I have found an amazing python module to achieve this (docx). To achieve this, I am hooking to the create() function. However, I cant find a way to access the sales order lines inside the create function. Here is my code:

    def create(self, cr, uid, vals, context=None):
        if vals.get('name', '/') == '/':
            vals['name'] = self.pool.get('ir.sequence').next_by_code(
                cr, uid, 'sale.offer') or '/'
            order_lines = vals.get('order_line')# How do I get things like order item names and quantities
        return super(sale_offer, self).create(cr, uid, vals, context=context)

Any ideas will be highly appreciated.
