I'm trying to create a Ruby gem that returns html mark up like so:
class Hola
def self.hi(name = "world")
"hello #{name}"
end
def self.hi_with_markup(name = "world")
"<strong>hello #{name}</strong>"
end
end
However, whenever I try to use it in a test.html.erb file like so:
<%= Hola.hi_with_markup(", please work!") %>
It returns the string with the tags printed instead of actually rendering the html. How can I fix this from the gem side?
Thanks!
In Rails 3 the default changed from "not" escaping HTML to escaping HTML (i.e. converting things like '>' to >) for any String deemed to be unsafe; which is generally any string that has the potential to have user characters, including the output of your gem. There are two ways around this raw() and .html_safe.
Here's a comprehensive answer: raw vs. html_safe vs. h to unescape html
The short answer is to do this:
<%= Hola.hi_with_markup(", please work!").html_safe %>
or
<%= raw(Hola.hi_with_markup(", please work!")) %>
Try this:
class Hola
def self.hi(name = "world")
"hello #{name}"
end
def self.hi_with_markup(name = "world")
"<strong>hello #{name}</strong>".to_html
end
end
