Get Item data in sub-item view

[DerAlSem]

Hi,

I've list of features.

class Feature < ActiveRecord::Base
 has_many :assets, dependent: :destroy
end

and assets, that belongs to feature:

class Asset < ActiveRecord::Base
  belongs_to :feature
  validates :feature_id, presence: true
end

i have one sample feature in db, and a link to show assets for this feature:

<td><%= link_to 'Show Assets', assets_path %></td>

Now, when i follow the link, list of assets is shown. Actually it is empty, as there are no assets in database. I need to show what feature this assets are belongs to (there're no assets, but that shouldn't make any difference).

I've tried with this:

<h1>Listing Assets for <%= asset.feature.try(:engtitle) %></h1>

getting 

undefined local variable or method `asset' for #<#<Class:0xb4ce52e8>:0xb55c4440>

and this

<h1>Listing Assets for <%= @feature.try(:engtitle) %></h1>

raising exception, but there's definitely engtitle for this feature in database.

What am i doing wrong?

Thanks

<h1>Listing Assets for <%= asset.feature.try(:engtitle) %></h1>

If there are no assets, what is `asset` set to? Clearly it's set to nil right now, but what did you think it should be set to, and why?

<h1>Listing Assets for <%= @feature.try(:engtitle) %></h1>





What is the exception being raised here?

Please show the controller so we can tell what is being set up for the view.
