ruby on rails - Error: undefined method `each' for nil:NilClass -

i'm getting error: undefined method `each' nil:nilclass when trying render choose_album_to_add.html.erb :

<table class="table_">   <thead>     <tr>       <th>album</th>     </tr>   </thead>    <tbody>     <% @albums.each |album| %>       <tr>         <td><%= album.name %></td>       </tr>     <% end %>   </tbody> </table>  <br> 

my users_controller.rb

def choose_album_to_add        @albums = album.all end 

what wrong? edit

as asked, i'm sure view file choose_album_to_add.html.erb in /app/views/users . , i've route this:

match '/addalbum/:id', to: 'users#choose_album_to_add', via: 'get'

of course, i'm typing /addalbum/45 on browser, , routes properly. view loaded sure, problem instance vars declared on controller can't accessed on view . =[

i've scaffolded 4 resources , they're working fine following conventions of declaring instance variables , using in views. know there alternative ways ( passings locals ) want job way.

the log console when tryng access

when run album.all on console get:

which 2 tuples inserted via rest methods generated scaffold.

any appointments more? thanks

your method def choose_album_to_add private - move definition above private statement.

since choose_album_to_add action has public method used view. think proved method wasn't being called when tried set @albums = 1 , didn't make difference.
