Question

Here is the relevant line from my rake routes:

 client_note GET    /clients/:client_id/notes/:id(.:format)      notes#show

When I try passing in the objects like <%= client_note_path([client, @notes.first]) %>> I get:

No route matches {:action=>"show", :controller=>"notes", 
:client_id=>[#<Client id: 5, ... , #<Note id: 9, ...]}

Which made me think to try a client ID. So, I tried: <%= client_note_path([client.id, @notes.first]) %>

which gives me:

No route matches {:action=>"show", :controller=>"notes", :client_id=>[5, 
#<Note id: 9,content: "He just bought a brand new bobcat, be sure to charg...", 
client_id: 5, created_at: "2012-06-11 16:18:16", 
updated_at: "2012-06-11 16:18:16">]}

Which, made me want to try just passing in a client ID. <%= client_note_path(client.id) %>

No route matches {:action=>"show", :controller=>"notes", :client_id=>5}

Still not what I’m looking for. I want to be able to show an individual note which can normally be found at a url like looks like: http://localhost:3000/clients/2/notes/3/

What object(s) does it expect?

root to: 'clients#index'

match '/signup',  to: 'users#new'
match '/signin',  to: 'sessions#new'
match '/signout', to: 'sessions#destroy', via: :delete

Additional Info:

Changing the line to <%= client_note_path(client, @notes.first) %> results in:

No route matches {:action=>"show", :controller=>"notes", :client_id=>#<Client id: 6, 
company_name: "John and Sons Roofing", contact_name: "John Wonder", phone_number: "1-    
555-283-9999", email_address: "[e-mail]", street_address: "13 Oak Street", city:
"Oakville", state: "Iowa", zip: "53457", image_location: "http://image-
location.com/image/john.jpg", created_at: "2012-06-11 16:18:16", updated_at: "2012-06-11    
16:18:16", url: "www.johnroofing.com">, :id=>nil}

Which gives me an id of nil. But, I have <%= @notes.first.blank? ? "No Notes" : @notes.first.content%> and that returns the notes content, so I don’t understand why it doesn’t work. Also, let’s try it with id, just for fun! <%= client_note_path(client.id, @notes.first.id) %>

And now we get: Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id. Looking into the DB, the ID of the note is 9 and 5 for the client.

Answer 1

I believe your issue is that you are putting the objects into an array as a single parameter rather than just passing two parameters. The proper way is

client_note_path(client, @notes.first)

Note that you can pass in the object itself (as shown), or the id of the object for either or both.
