So I've got some objects that I'm passing as a collection:
所以我有一些作为集合的对象:
@things = Thing.all
And in my view:
在我看来:
<%= f.input :things, :collection => @things, :as => :check_boxes %>
Is there any way to specify which of the objects should already be checked when the view is loaded?
在加载视图时，是否有方法指定应该检查对象的哪一个?
Thanks!
谢谢!

In your controller's "new" action, you want to initialise the form object with the values you want by default:
在控制器的“新”操作中，您希望在默认情况下初始化表单对象:
def new
@post = Post.new
@post.things = [@one_thing, @another_thing]
end
This can also be done as an after_initialize hook in the model itself.
这也可以作为模型本身的after_initialize钩子来完成。
