I considered adding this feature when I addressed your earlier post, but the
problem is that the user() method (i.e., the objects_by_map get_set_on_save
method) accepts arguments in the following forms:
* A single undef arg
* A list containing any combination of the following:
- An object of the appropriate class
- A reference to a hash containing method name/value pairs
- A scalar primary key value
It's that last one that causes problem. The arguments you suggested look
like two scalar primary key values, "with_map_records" and "1".
So, asking that map records be included on a per-method-call basis is
probably out. But if you *always* want map records with your m-to-m
objects, just add to the relationship's manager_args:
relationships =>
[
users =>
{
type => 'many to many',
map_class => 'ProjectUserMap ',
manager_args => { with_map_records => 1 },
},
...
]
Even if you only want the map records sometimes, asking for them always
shouldn't add much overhead. Map records tend to be small.
