How can I check if user is signed in with rails devise?

Question

I am trying to add the header to my rails application based on authenticating the user. So here I am checking that if the user has logged in or signed in and then adding login/logout link based on that.

But I am getting the following error:

application.html.erb:16: syntax error, unexpected tSYMBEG, expecting keyword_do or '{' or '(' ...roy_user_session_path, method :delete );@output_buffer.safe_

Here's what I have tried:

<% if user_signed_in? do %> 
    <%= link_to "Log out", destroy_user_session_path, method :delete %>
<% else %>
    <%= link_to "login", new_user_session_path %>
<% end %>

How can I resolve this?

Answer 1

First of all remove do from this line, you don't need that

<% if user_signed_in? %>

Secondly add : after method , it's a key value pair

<%= link_to "Log out", destroy_user_session_path, method: :delete %>

Hope that helps!

You are making a syntax error in method delete. Copy the below code

<% if user_signed_in? %>
    <%= link_to "Log out", destroy_user_session_path, :method=>'delete'%>
<% else %>
    <%= link_to "login", new_user_session_path %>
<% end %>
