Couldn't find Model without an ID from application_controller.rb - ruby-on-rails

Question

I am trying to create a session for a model called Commuter by defining a helper method in application_controller.rb file. As follows.
application_controller.rb
helper_method :current_commuter
def current_commuter
#commuter ||= Commuter.find session[:cid]
end
After verifying the commuter's phone number I am trying to create a
login session.
commuters_controller.rb
def verify
#commuter = Commuter.where(phone_number: params[:phone_number]).first
if (#commuter && #commuter.authenticate_otp(params[:otp],drift:300))
#commuter.auth_active = true
if #commuter.save
#Removed from session after verified it
session[:phone_number] = nil
session[:is_verified] = nil
#signed in commuter after verified it
sign_in(:commuter, #commuter)
flash[:notice] = "Your mobile no is verified."
end
else
flash[:alert] = "You have entered wrong otp.Please check again."
end
puts "#{current_commuter.phone_number}"
redirect_to root_path
end
I put a puts to check if the current_commuter is working or not. It is when I checked on the console. Now when I added few links on a view file as follows:
app/views/bookings/outstation.html.erb
<%if current_commuter.present? %>
<li> <%= link_to "Dashboard", dashboard_commuters_path %> </li>
<li> <%= link_to "Logout", destroy_commuter_session_path, method: :delete%></li>
<%else%>
<li>
<a href="" data-toggle="modal" data-target="#signinmodal">
REGISTER | LOGIN
</a>
</li>
<%end%>
Now I am getting the following error:
ActiveRecord::RecordNotFound in BookingsController#outstation
Couldn't find Commuter without an ID

Answer 1

It looks to me like the error's thrown here:
def current_commuter
#commuter ||= Commuter.find session[:cid]
end
Are you calling this as a before_action?
Using find raises an error if a record's not found, so I'd suggest you're either not passing in an id in session[:cid], or what you are passing doesn't match a Commuter in your db.
You can use find_by_id to avoid throwing an error (it returns nil if the record's not found), or work around this to ensure the method's only called where it should be.
Does that help?
Edit: Based on your additional info, this could be coming from any of the finds in the bookings_controller. Same explanation as above though :)
