Adding onto end of many in 1-m CMP/CMR

[cyates]

Hi,

I have a User which has many activities, each activity is owned by one user.

Using CMR to manage this relationship I am having to do User.getActivities().add(ActivityLocal.create(blah,blah)).

Does this mean that every time I add an activity every other activity is being loaded from the database (for that user)?

This seems very inefficient. Is there another way? I simply want to insert a new row into the activities table.

Thanks

That is the way it works now. I remember there is a reason for this, but can't remember the reason right now; I'm still a little tired.

Hard night/day?

Yep I closed 3 bugs last night at about 2 am.

Ok now I remember. You call User.getActivities() which causes the load. The code assumes that if you are getting the collection you plan on using it, which looks like a bad assumption in the light of this code.

When I rewrite this code next time, I'll think about your code. In the mean time, can you set the relation the other way arround:

ActivityLocal.create(blah,blah).setUser(user);

That should not cause a load, but I can't be certain.

OK. Hadn't thought of that :)

Thanks
