Rails layout not changing between actions
Question
I'm programming a Rails application. I want to use an specific style in the whole HTML tag in the index page, but the rest of the pages should follow the application layout. So, in my controller I have:
def index
render layout: 'index_layout'
end
# All other actions follow this scheme
def any_other_action
end
The index layout has an specific piece of code that changes the styling:
<!-- Index layout -->
<html id="index_html">
...
<!-- Application layout (goes normally) -->
<html>
...
However, when I change from window to window through a link_to tag in Rails, the layout is not being refreshed and the view remains with the id assigned in the previous page, for example, if I go from index to any other page, the html tag has the id index_html, and vice versa. However, if I perform a full refresh (by pressing F5 key), the layout is rendered properly. I tested in Mozilla Firefox and Chrome, in order to check if this was a browser peculiar issue, but the results are the same.
My server produces this output when I request index page, after I navigate to any other page through link_to tag and then reload this new page:

Can anyone give me some lights about what could be failing? My intuition is something about cache, but I can't find any answer that can help me. My Ruby version is 2.5.1 and my rails version is 5.1.6

我认为获取Ur客户布局的最简单方法是创建一个布局，其中控制器的名称为文件夹名称，索引为index.html.erb以反映Ur的操作。

1)
before_action custom_layout, only: :index
def custom_layout
render 'layouts/index_layout'
end
2)
layout :layout_by_resource
def layout_by_resource
if true #just check as you want here. controller/path/actions etc...
"index_layout"
else
"application"
end
end

I post this expecting this will be helpful for anyone with the problem I presented
The issue was the turbolinks gem. It appears that when you create a link with this gem, it reloads only the body of the page. For this reason, the html tag wasn't changed when redirected through a link but it was when refreshed. All I had to do was to add in my link tags the next code:
<%= link_to about_us_path, data: {turbolinks: false} %>
And so, the layout is fully redrawn, applying the desired changes.
Thanks to all for their answers!
