I have an error in my nifty_scaffold... For some reason (didn't change any standard code, checked the routes.rb, ...), creating a new nutrition won't work.
Could anyone explain me how and what the solution is?
I think i have included all necessairy code...
The error in detail is: undefined method `generated_methods' for nil:NilClass
Route contains:
map.resources :nutritions
View: New
<% title "New Nutrition" %>
<%= render :partial => 'form' %>
<p><%= link_to "Back to List", nutritions_path %></p>
View: _form
<% form_for @nutrition do |f| %>
<%= f.error_messages %>
<p>
<%= f.label :name %><br />
<%= f.text_field :name %>
</p>
<p>
<%= f.label :description %><br />
<%= f.text_area :description %>
</p>
<p>
<%= f.label :ammount %><br />
<%= f.text_field :ammount %>
</p>
<p>
<%= f.label :unit %><br />
<%= f.text_field :unit %>
</p>
<p>
<%= f.label :kcal %><br />
<%= f.text_field :kcal %>
</p>
<p>
<%= f.label :protein %><br />
<%= f.text_field :protein %>
</p>
<p>
<%= f.label :carb %><br />
<%= f.text_field :carb %>
</p>
<p>
<%= f.label :fat %><br />
<%= f.text_field :fat %>
</p>
<p>
<%= f.label :type %><br />
<%= f.text_field :type %>
</p>
<p>
<%= f.label :class %><br />
<%= f.text_field :class %>
</p>
<p><%= f.submit "Submit" %></p>
<% end %>
And my nutrition controller
def new
@nutrition = Nutrition.new
#raise @progress.inspect (debug porpose, didn't help)
end
And this is the full Trace
