Hello, I am trying to create an on_change method that uses an id of a many2one field. When I change the value of the many2one field, it doesnt pass in the id as the parameter like i need it to. Here is an example of my code

def on_change_sql_min_max_ver(self, cr, uid, prod_ver_id, context=None):
    sql_ver_dictionary = {}
    prod_ver_rec = self.pool.get('product.version').browse(cr, uid, prod_ver_id)
    sql_ver_dictionary['sql_min_ver'] = prod_ver_rec.sql_min_ver
    sql_ver_dictionary['sql_max_ver'] = prod_ver_rec.sql_max_ver
    return {'value': sql_ver_dictionary }

Here is the xml field

<field name="product_version_id" on_change="on_change_sql_min_max_ver(product_version_id)"/>

Does anyone know why the Id wouldnt be passed in when I change the many2one field? When I run this code this is the error that I see, and I know its because the Id is not being passed in

Your method syntax is wrong. You need to add ids parameter in your method.

def on_change_sql_min_max_ver(self, cr, uid, ids, prod_ver_id, context=None):

ids contains list of ids if your record exist in database (It is saved and you are updating the field), if you are creating a new record then ids will contains blank list.

Try adding an "ids" parameter in your function definition: 

def on_change_sql_min_max_ver(self, cr, uid, prod_ver_id, context=None):

to

def on_change_sql_min_max_ver(self, cr, uid, ids, prod_ver_id, context=None):
