Error with jbuilder 0.8.2 : "missing attribute: photo_updated_at"

[youboox]

Hi,

After updating my Rails 3.1 to 3.2 i have this error in one of my jbuilder partial :

Failure/Error: get :show, :id => @user.to_param, :format => :json
ActionView::Template::Error:
missing attribute: photo_updated_at
# ./app/views/api/user_ipads/_user_ipad.json.builder:11:in block in _app_views_api_user_ipads__user_ipad_json_builder__4322258879011176669_70322613825420' # ./app/views/api/user_ipads/_user_ipad.json.builder:1:in_app_views_api_user_ipads__user_ipad_json_builder__4322258879011176669_70322613825420'
# ./app/views/api/user_ipads/show.json.jbuilder:1:in _app_views_api_user_ipads_show_json_jbuilder___1496169294239287635_70322552739840' # ./spec/controllers/api/user_ipads_controller_spec.rb:56:inblock (4 levels) in <top (required)>'

This is very strange since my model has the photo_updated_at column, and i can access it without problem outside the jbuilder partial. Here is the line that create the issue :

Line 11 : json.photo @user_ipad.photo.url

json.user_ipad do |json|
json.id @user_ipad.id
json.is_premium @user_ipad.is_premium
json.email @user_ipad.email
json.authentication_token @user_ipad.authentication_token
json.pseudo @user_ipad.pseudo
json.first_name @user_ipad.first_name
json.last_name @user_ipad.last_name
json.male @user_ipad.male
json.birthday @user_ipad.birthday
json.photo @user_ipad.photo.url

end

Do you have any idea where it could come from ?

Thanks,
Vincent

I don't see it in your code example. I don't think this relates to jbuilder itself. But if you can replicate it in a failing test, please reopen.
