How to get in openerp all objects from a class?

问题

I need to get all objects from a class and iterate through them. I tried this, but without any results:

def my_method(self, cr, uid, ids, context=None):
    pool_obj = pooler.get_pool(cr.dbname)
    my_objects=pool_obj.get('project.myobject')
    #here i'll iterate through them...

How can I get in 'my_objects' variable all objects of class 'project.myobject'?

回答1:

You have to search with empty parameters to get all the ids of existing objects, like:

myobj = pool.get('project.myobject')
ids = myobj.search(cr, uid, [])

Then you can browse or read them passing an id or the list of ids.

回答2:

It seems you forget to import pooler.

from openerp import pooler

May it will help you.
