How can I change a body tag ID based on the page title in rails? -
using ruby on rails (5) want use if statement change id of body tag based on view rendering. want use background image on home page only, , not on other. want fill screen, if put on page it's self comes border. want attache body tag in application.html.erb view id tell css load background image. can't :title tell erb there , make statement true.
i using provide on view page so:
<% provide(:title, "home") %> then in application.html.erb page trying use if statement put in body tag or without css id background image based on provided :title, so:
<!doctype html> <html> <head> <title><%= yield(:title) %></title> ... </head> <% if :title == "home" %> <body id="home-background"> <% else %> <body> <% end %> but doesn't seem work. title 'yield' , display in address bar, not in if statement. have tried put yield(:title) in variable , rails didn't that. first solo rails project, , know should possible, can't find how correctly, appreciated.

###application.html.erb <body> <div class="<%= @title=="user" ? 'user_wrapper' : 'default_wrapper' %>"> </div> </body> ##css .user_wrapper{ background: url(user_background.jpg) no-repeat center center fixed; } .default_wrapper{ background: url(default_background.jpg) no-repeat center center fixed; } hope helps.. :)
