What I want to do is check if current user already have a shop or not, if current user has a shop I want to show him link to his shop otherwise a button to add a shop. How can i do this in rails using the if statement.

Answer 1

Possible you would use erb syntax:

<% if current_user&.shop_id %>
  <%= link_to "/shop/#{current_user.shop_id}" %>
<% else %>
  <%= link_to "/add-shop" %>
<% end %>

Answer 2

You can use present? method.

current_user.shop.present?

it returns true if there is any ActiveRecord Data available. please also note the comment on this answer. from @obermillerk

Answer 3

you can use any?

current_user.shop.any?

Returns true if there are any records
