Sorting an associated EmbeddedDocument

[overture]

Hi,

How can you sort on an assoicated EmbeddedDocument? For instance, if
I have a "Post" Document and a "Comment" EmbeddedDocument - how can I
sort the comments by "created_at".

I tried...

>> post = Post.first
>> post.comments(:order => "created_at")

...but it didn't seem to work. I'm sure I'm doing something stupid
but I can't work it out!

Thanks!
Phil

Do you have

timestamps!

set in your model? If not there is no created_at column.

Yeah, I have a created_at column.

I think you could do:

post.comments.sort_by(&:created_at)

And get the same result. But I don't know if that would be the best
way to do it.

Excellent! Thanks Gustavo, that seems like a really nice way to do
it. Also, to get descending order use:

post.comments.sort_by(&:created_at).reverse

Thanks!
