How to use authentication logic to create two different link_to locations (Ruby on Rails & Devise)-CodePudding

First post on StackOverflow. :) Am new to Ruby on Rails (and coding in general), and I am struggling the most with understanding documentation. So I am sure this answer is out there somewhere, but if it is, I didn't find/understand it.

I am trying to create two options:

Click on logo before login- route to root_path
Click on logo after login- route to alerts_path

This solution below works, but there must be a better, more tidy and concise way to write it instead of repeating all of that code???

<% if user_signed_in? %>
  <%= link_to alerts_path, class: "d-flex flex-row navbar-brand", input_html: {data: {bs_toggle: "offcanvas", bs_target: "#offcanvas"}} do %>
    <%= cl_image_tag("ouicity_logo_j5rhro") %>
    <h2 id="logo" >ouicity</h2>
  <% end %>
<% else %>
  <%= link_to root_path, class: "d-flex flex-row navbar-brand", input_html: {data: {bs_toggle: "offcanvas", bs_target: "#offcanvas"}} do %>
    <%= cl_image_tag("ouicity_logo_j5rhro") %>
    <h2 id="logo" >ouicity</h2>
  <% end %>
<% end %>

CodePudding user response：

A possible simple refactor (DRY code) is too just add logic for the url change (using the ternary operator):

<%= link_to user_signed_in? ? alerts_path : root_path, class: "d-flex flex-row navbar-brand", input_html: {data: {bs_toggle: "offcanvas", bs_target: "#offcanvas"}} do %>
  <%= cl_image_tag("ouicity_logo_j5rhro") %>
  <h2 id="logo" >ouicity</h2>
<% end %>

You can eventually extract this logic to a helper to keep your view simpler:

def logo_path
  user_signed_in? ? alerts_path : root_path
end

<%= link_to logo_path, ...
