Question

On every page we have a condition like this for guest user.

<% if not_guest? %> 
<% link_to "show", path %>
<% end %>

<% if not_guest? %> 
<% link_to "delete", path %>
<% end %>

<% if not_guest? %> 
<% link_to "edit", path %>
<% end %>

for which link should appear or not for guest user.

Are there any better ways to handle this scenario instead of writing the conditions for every link ?

Answer 1

Make a helper:

#helpers/application_helper.rb
def link_to_unless_guest(*args)
  if not_guest
    link_to(*args)
  end
end

Then call like

<% link_to_unless_guest "show", path %>
