Question

I want to know that is there any rel attribute in <%= link_to_peramlink %> like tag in html has.

For example:
in html
my link

I have <%= link_to_permalink article,”con”, nil, “my link”, “5m” %> in rails. Is there any rel attribute in that?

Answer 1

link_to_permalink is not a standard Rails helper. A simple:

<%= link_to article.title, article %>

(you might have to adjust article.title) will get you a link to the article, assuming something like resources :articles is defined in routes.rb.

Setting a rel attribute is trivial:

<%= link_to article.title, article, :rel => 'nofollow' %>

or other attributes:

<%= link_to article.title, article, :rel => 'nofollow', :class => 'my-css-class' %>

Finally, I don’t know what your link_to_permalink helper does, but you can use to_param to make seo-friendly permalinks: see here. (This is the “Rails Way,” if you know what I mean.)
