Rails production error ActiveRecord::RecordNotFound (Couldn't find Person without an ID)

Question

I have very strange error only in Rails production environment. In development works good. The logs show error in this line in my index.html.erb file.

This is the production log error:

ActiveRecord::RecordNotFound (Couldn't find Person without an ID):
  app/views/seeds/index.html.erb:71:in `block in _app_views_seeds_index_html_erb__4016841983995682700_31529840'
  app/views/seeds/index.html.erb:61:in `each'
  app/views/seeds/index.html.erb:61:in `_app_views_seeds_index_html_erb__4016841983995682700_31529840'
  app/controllers/seeds_controller.rb:17:in `index'

The line in my seed index file is this one:

<td><%= Person.find(seed.person_id).name %></td>

Before this line I query other data in the same way with foreign key and it works. When I check the sql table I see that the Seeds table has the person_id value.

Moreover, when I query the same thing via the rails console in production environment i receive the result without any problems. But when I load the page it shows me "The page you were looking for doesn't exist." and the production.log shows the error above... Any ideas what might be wrong?

Sorry guys after a whole day of coding by brain was not to good. The point is that in the middle of the table I had a NULL object for person and that was causing the error... Thank you for your time
