Let's say I have an index view with this kind of hierarchy...
Raw
gistfile1.txt
= render sidebar #no caching
= render partial:patrol, collection:@patrols #has a cache key for patrol
= render partial:users, collection:patrol.users #has a cache key for user
Raw
rake output
rake cache_digests:nested_dependencies TEMPLATE=manage/manage/index
[
"manage/manage/sidebar", #Didn't expect this because I don't cache it (yet)
{
"manage/manage/users": [
{
"manage/manage/patrol": [ #Expected this
"manage/manage/user", #Expected this
"manage/manage/add_new_member" #Expected this
]
},
"manage/manage/add_new_member" #Expected this
]
}
]
I sort of expected it to only list the dependencies for which I had set up cacheing, rather than all the dependencies it could figure out.

The second file is just pseudo-code to show the index page's rendering hierarchy. I added comments to show what I expected and didn't expect as output. I hope this makes sense.

Now that I understand that the rake task shows all the view dependencies whether or not the partials are cached, it makes sense and I think the rake task is correct. I was just wondering if the rake task should be explained in a way that people will not be confused as I was.

Ah, I see. Yeah, there's no way of doing that. This just shows the nested dependencies between templates. That's by design. Feel free to see if you can improve the message, though.
