ruby on rails - Get last occurence of nested array -

-

By querying two sections and applying the following methods: 

  .each_with_index. Chunk {| Enum, i | I get this structure:  
  [[False, [[# # Post ID: 1, Title: enum.is_a? (Note)}  
 
 "something", 0]]], [false, [[# # and #; Lit; Post ID: 2, Title: "Something", 1], [# & lt; Post ID: 3, Title: "Something", 2]]], [True, [ID # 1, Title: "Something", 3], [# & lt; Note ID: 77, Title: "Something", 4]]]]

In the scene, I have to know when I am on the last object, in this case the index status 4, I How do i

In this view, you could just do this: 

  array .flatten.last

which looks like this: 

  [1] PRI (main)> gt; [[False, [["1"]]], [false, [2]], ["post 3"]], [true, [1], ["note 77"]]]] .flatten Last = & gt; "note 77"

Thanks for the amendment Cary.

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 "...
