I trying to achieve something like as below :-
<%= link_to "<%= user.email %>", users_path %>
So that each user's email id is to be used as a hyper link to their user profile page.
How to achieve this ? I'm using rails 3.0.1.
Thanks in Advance
Don is close, but users_path is (i presume) the index action of a UsersController, so you don't need (and in fact shouldn't pass) user into the helper.
link_to is actually a helper method, which accepts a few arguments. The first argument is the text of the link itself (what goes in between <a> and </a>). You don't need to use the ERB syntax you are trying to use, just pass whatever text you want (user.email, or user.name, whatever).
<%= link_to user.email, user_path(user) %>
h(user.email) instead of user.email
users_path goes to an #index action, so this answer actually will link everybody's email address to the (presumably) "all users" page. Furthermore, pace Don below, user_path(user) is a synonym for user in this example, so the whole thing can be simplified as <%= link_to user.email, user %>.
Try the following, since you want a link to a user and not the index of all users
<%= link_to user.email, user_path(user) %>
