Ruby on Rails中的自动保存选项

Question

Is there a way to turn OFF autosave in Rails? I don't want modifications to an association to automatically save to the database UNTIL I call save on the parent object.

some_parent.some_children << child #should not save, just adds to the association!

some_parent.save #now parent and children are saved!

It this possible or am I barking up the wrong tree?

Answer 1

I think this may be close enough to provide some help.

some_parent.some_children.build({:child_attr1 => 'child_val1'})
some_parent.save # should save the new child as well

Answer 2

我认为您只需要声明带有autosave的some_children关联：false
