Flash and rails with HTML

Question

I'm trying to put a simple smiley into a flash message like so:

flash[:info] = "Please check your email to activate your account &#9786;"

from the controller

if @user.save      
   flash[:info] = "Please check your email to activate your account &#9786;"

How do I get ruby to execute this code, it worked right then as I typed the question, but on my rails app not so lucky. I am rendering my flash as a partial on the application.html.haml page that simply loops through the flash messages and displays the message.

_flash.html.haml:

-flash.each do |message_type, message|
    =content_tag(:div, message, class: "alert alert-#{message_type}")

You can use sanitize() to render html entity instead of escaping it:

=content_tag(:div, sanitize(message), class: "alert alert-#{message_type}", escape: false)

That looks like a view rendering to me – Spencer Hire May 02 '15 at 03:45

@SpencerHire: Well, in your view, sanitize your output (where you display your flash messages). – potashin May 02 '15 at 03:46
Thanks but, adding sanitize(render 'layouts/flash') in application.html.haml doesn't help. – Spencer Hire May 02 '15 at 03:51

@SpencerHire: not like this, exactly in the `layouts/flash` file, where you output you messages. – potashin May 02 '15 at 03:52
Yah, tried that in the flash partial also, no luck. – Spencer Hire May 02 '15 at 03:53

@SpencerHire: you are doing it wrong, just post your `layouts/flash` file in the question. – potashin May 02 '15 at 03:54

@SpencerHire: What is your rails version by the way? – potashin May 02 '15 at 03:54
Ok no worries, version = 4.2.0 – Spencer Hire May 02 '15 at 03:55
Thanks that worked :-), you wouldn't happen to know how to interploate link_to's into flash also? – Spencer Hire May 02 '15 at 03:58
