Update or modify object field value using self.pool in python

Question

Below is my code for field on_change
My form view xml
<field name="x_project_id" on_change="onchange_project(x_project_id,partner_id)" string="Project" />
Python code is below:

def onchange_project(self, cr, uid, ids, project_id, client_id, context=None):
if project_id:
obj		= self.pool.get('res.partner').browse(cr,uid,project_id,context=context)
val1	= obj.name
val2	= obj.x_project_value

Is there any way I can update res.partner by using similar to below
self.pool.get('res.partner').update(

If you wanted to update a record of particular model you can call write method. here is the sample code
partner_obj = self.pool.get('res.partner')
partner_obj.write(cr, uid, partner_ids, {'name': 'new_name'}, context=context)
when you write onchange method as per odoo v7 it should return  dictionary . i.e.
def onchange_project(self, cr, uid, ids, project_id, client_id, context=None):
'''your code'''
return {'value': {'field': 'my value'}}
