In Sinatra, using erubis, the default setting for escape_html is true.
But sometimes I want to to unescape, because, I do not want to add too much escape_html. Don't repeat yourself. :)
helpers:
def raw(string)
CGI::unescape_html(string)
end
views:
<div class="body">
<%= raw "<h1>Thanks for help...</h1>" %>
</div>
does not work.
On
You can accomplish what you want this way:
Web.rb:
require 'sinatra'
require 'erubis'
set :erb, :escape_html => true
get '/hi' do
@model = Hash.new()
@model[:person] = "<b>World</b>"
erb :hello
end
Layout.erb:
<!DOCTYPE html>
<html>
<head>
<title><%= @title %></title>
</head>
<body>
<%== yield %>
</body>
</html>
Hello.erb:
<div>
<p>Hello, <%= @model[:person] %>!</p>
<p>Hello, <%== @model[:person] %>!</p>
</div>
Not sure about which version of Erubis you use, but it seems like it has a special kind of tag for that particular case: with two equals signs. So the line from your example might look like:
Calling to
CGI::unescapeshould not be necessary, because the string is initially not escaped. All you need is to prevent escaping, not undo it.But if your Erubis don't understand
<%==, or if you use ERB, not Erubis, then sorry, I don't know any other solution except of what you said: disable html escape for entire file and useheverywhere you do need escaping.FYI, in Rails for this also there are special helpers
rawandString#html_safe, but as I can see they are part of ActiveSupport and not available in Sinatra.
