Can't access Rails association in view

I'm struggling to get an association to work properly in Rails. I'm just learning the language, so any help is really appreciated.

I have:

class Feedback < ActiveRecord::Base
    belongs_to :section
end


class Section < ActiveRecord::Base
    has_many :questions
    has_many :feedbacks
end

My 'feedbacks' table has a 'section_id' column.

Then in my /show.html.erb in sections I have:

<% @section.feedback.each do |feedback| %> 
  <%= feedback.name %> 
<% end %>

And I get the following error:

undefined method `feedback' for #<Section:0x007fa70dd2dc58>
Did you mean?  feedbacks
               feedbacks=

What have I done wrong?

Did you try making the feedbacks plural?

<% @section.feedbacks.each do |feedback| %>

Here's the link to has_many association.

Note that you pluralized it properly in the model definition.

Since you are working with a has_many association, when referring to the associated class, you should always use the plural tense. In this case, feedbacks instead of feedback. Note that this is only true for this direction. If you were to try and find a feedback's section you would keep it singular: @feedback.section.
