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(<a
href="/projects/1"><img alt="Show"
src="/images/icons/show.png?1285276800" /></a>
CODE:
--Here is my app/views/projects/index.html.erb
<title> <p> Projects </p></title>
<%= render @projects %>
--app/views/projects/_projects.html.erb
<div class="project">
<%= project_title_links(project) %>
</div>
--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 On Jan 3, 2011, at 10:10 PM, Ravi Kukreja wrote:> Hello: > I am learning to use Helpers in Rails 3. > I have a project model with ''Name'' attribute in it.

Thanks for your response. I tried adding .html_safe to the following, but its still outputting the same. --app/views/projects/_projects.html.erb <div class="project"> <%= project_title_links(project).html_safe %> </div> -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

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 cheers sameera On Jan 3, 11:10 pm, Ravi Kukreja <li...-fsXkhYbjdPsEEoCn2XhGlw@public.gmane.org> wrote:> Hello: > I am learning to use Helpers in Rails 3. > I have a project model with ''Name'' attribute in it.

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
