Rails 4 - HTML in Helper Returning a Hash

Question

Trying to create a simple helper that returns this to my view:

<hr id="effects">

The helper I created looks like this:

def bar(id)
  content_tag(:hr, id: id)
end

When I call

<%= bar("effects") %>

The helper correctly displays the <hr> but the id is being displayed directly to the page like {:id=>"effects"}

I am assuming I am doing this wrong, but can't seem to find anything that can help me. I appreciate any help.

Answer 1

content_tag(name, content_or_options_with_block = nil, options = nil, escape = true, &block)

the second param is content, you can try

def bar(id)
  content_tag(:hr, "", id: id)
end

Answer 2

As per the documentation

def bar(id)
  content_tag(:hr, "", id: id)
end

However, I wonder why you have created a helper method for this. You can do it directly on views (its recommended also).
