Link_to displaying html instead of link

Rails
1

Hello:
I am learning to use Helpers in Rails 3.
I have a project model with ‘Name’ attribute in it. I want to display
all the Projects with a ‘Show’ link next to it. The Problem is instead
of displaying a link for ‘Show’ it is displaying the html(Show

CODE:
–Here is my app/views/projects/index.html.erb

Projects

<%= render @projects %>

–app/views/projects/_projects.html.erb

<%= project_title_links(project) %>

–app/helpers/people_helper.rb

module PeopleHelper
def project_title_links(project)
content_tag :h1 do
[ project.title,
link_to_icon(‘show’, project)
].join(’ ')
end
end
end

–app/helpers/application_helper.rb

module ApplicationHelper

def link_to_icon(icon_name, url_or_object, options={})
link_to(image_tag(“icons/#{icon_name}.png”),
url_or_object,
options)
end

end

helpers are automatically scrubbed in rails 3. Try adding .html_safe to
the return value

Thanks for your response. I tried adding .html_safe to the following,
but its still outputting the same.

–app/views/projects/_projects.html.erb

<%= project_title_links(project).html_safe %>

Hi Ravi,

Its because with rails3 they have implemented script safety by
default. If you want to print html/script codes you need to
explicitly declare it. try this

<%= raw project_title_links(project) %>

should work

Although this will work, it seems like bad form to do this for helpers
in the view.
IMO, if the helper is intended to return renderable html, it should.
Simply add .html_safe to
the end of .join() in your helper --> .join(’ ').html_safe

Hope this helps
