Re: [Rails] Join table query error

The code in your view should be:

<% @pictures.each do |picture| %>

    <%= image_tag(picture.image %>
<% end %>

without @

Hi,
I'm learning Rails and am getting an error following a query.  I think
I'm missing something simple and would appreciate guidance.

In controller:
[code]@pictures = Question.find(session[:question_id]).pictures # Query
through the join table[/code]

@picture :
[#<Picture id: 44, title: "", remote_image_url: nil, contributor: "",
created_at: "2013-04-10 11:16:34", updated_at: "2013-04-10 11:16:34",
gallery_id: nil, image: "pict4.png">, #<Picture id: 46, title: "",
remote_image_url: nil, contributor: "", created_at: "2013-04-12
23:39:18", updated_at: "2013-04-12 23:39:18", gallery_id: nil, image:
"pict2.jpg">]

In view:
<% @pictures.each do |picture| %>
<%= image_tag(@picture.image %>
<% end %>

Error: undefined method `image' for nil:NilClass

Thanks
