ruby on rails - Unique locale yml path for /new and /edit when using partial -

-

I use partial _form for both new and edit Action / scene

I have this form: t (". Change_image")

The missing path path generated by the rail is the following 

  Translation is unavailable: en.users.form.change_image

but I have to do different text in en.yml if this new or edit , which means "add image" and "change image".

Do i have unique locale path action and partial? Such as 

  en: user: new: change_image:

< P> The current partially skips the key if the key starts with a period, then you have to use the full path in the t () . E.g., 

  t ("user. {{Params [: verb}}. Change_image")

c# - WPF Expander overlay used in ItemsControl -

-
I've been searching for a while, but all the solutions I can only deal with parts of my issue. With an item control, which includes the expansion, upon expansion, the content of the extensioner should be shown as an item which is overlapping the other item in the item control and not taking them down. The following XAML-code is actually a big problem: the content of the expansion does not overlap other objects but is hidden behind them, I think it is because of ZIndex because the following in ItemsControl Items are added after expander content. I managed to set a single spreader's ZIndex 99 style triggers, but it appears to be very complicated and error-prone solution any thoughts? & lt; Window x: orbit = "wpfTest.MainWindow" xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns: x = "http://schemas.microsoft.com/winfx/2006/ Xaml "title =" main window "height =" 350 "width =" 525 "...
