Useful Code Snippets

Here are some helpful code snippets – how to check if a user is logged in, how to display conditional content based on the type of user or if they are logged in, etc.

Testing for a logged-in user in a view

Add comment

<% if logged_in? %> <% else %>

You must be logged in to comment.

<% end %>

Conditional partials

<% if logged_in? %> <%= render(:partial => “shared/sideNavUser”) %> <% else %> <%= render(:partial => “shared/sideNavLogin”) %> <% end %>

Testing for a logged-in user in a view (alternative)

I have had issues with using the ’@’ instance variable notation inside of views. So, for example, @current_user never seems to work for me. However, ‘self’ works instead. So, I use the following snippet inside views:

Welcome user

<% if logged_in? %>

Welcome, <%= self.current_user.login %>

<% else %> <% end %>

Alternate for current user

current_user

(or whatever your accounted model is named) should work.
So, if your model is

Member

, there should be a

current_member
