   def reset_password_instructions(resource, opts={})
    @resource = resource

reset_password_instructions.html.erb

<p>Hello <%= @resource.email %>!</p>

<p>Someone has requested a link to change your password. You can do this through the link below.</p>

<p><%= link_to 'Change my password', edit_password_url(@resource, reset_password_token: @token) %></p>

<p>If you didn't request this, please ignore this email.</p>
<p>Your password won't change until you access the link above and create a new one.</p>

At this point, when user is created manually by admin, Password reset Link is going to the email address, which I can see using MailCatcher or letter_opener. http://ift.tt/1MG0D7C

I click on the link and it successfully took me to edit password page. When I submit form, ivalidation failed with Reset password token is invalid message.

What am I missing here....
