When using with Rails, nil is being sent to partials, causing "ActionView::Template::Error: Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id " #71

This is easier to show than describe, but after updating Jbuilder from 0.4.3 to 0.8.2, we are seeing errors where an instance variable that's being used in a template tries to render partials, even when it's nil.

I'm unable to repeat this issue with straight Jbuilder - it's only happening when used with Rails as far as I can tell, so this may need to be fixed on the Rails side. Jbuilder is the only thing I'm changing to cause these, however.

I will try to come up with a broken example app later, but I'm stuck in meetings for awhile and wanted to report this before I forgot.


# user.json.jbuilder
json.(@user, :id, :name)

# @friends is nil
json.friends @friends do |json, friend|
  json.partial! :partial => 'users/friend', :locals => {:friend => friend}

# _friend.json.jbuilder
json.(friend, :id, :name)



Seeing this too...
