var = self.search(cr, uid, ids, context)

will print the ids of the record.

if the ids is a list of ids then you have to write

var = self.browse(cr, uid, ids[0], context)

if ids is just a number representing an id of a record in the table related to the class, the id field, then this expression should work

As per your comment " i want to get the id of a current view which is not saved yet. "  I think you're working within the create method, in this case you have to call :

new_id = super(your_class,self).create(cr,uid,ids,context=context)

you can then use this new_id in your expression

var = self.browse(cr, uid, new_id, context)

print var.project

and it will work

What about the active_id???

var = self.browse(cr, uid, ids[0], context)
print var.project

May be this will help you.

var[0].project 

or

for var in self.browse(cr, uid, ids, context) :

    print var.project
