Hi guys, I''m part way through a RoR application, for some reason whenever I add new controllers (using scaffold) I get an uninitialized constant [name of controller] error. The first few controllers work fine, the only thing I can see that I''ve changed is the layout file (but scaffold creates a new layout for each controller so can''t see that being the problem). You can all probably tell I''m new to rails so hoping this is some newb error... the failing controllers can be found at http://spotter.derbyproject.com/exercises/list http://spotter.derbyproject.com/updates/ and working ones are here http://spotter.derbyproject.com/users Just for clarity, Ive been adding controllers as I go, but the last two added have given this error straight after running scaffold (I haven''t made any changes to them). thanks! -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

good call... sorry mate
line 11-13 look like this
def list
@exercises_pages, @exercises = paginate :exercises, :per_page => 10
end
which is the same as was generated for the previous controllers.
The page should be generating a list of exercises currently in the
database, it might be worth pointing out that exercises/new works, so
seems to be just the list method.
cheers.

I''m going to guess that it''s the latter. paginate is being smart and assuming that if you say exercises, then the name of the model is the singular (ie exercise). I''ll further guess that the difference is that when you created the scaffold you''ve recently been using the plural form, whereas you should be using the singular.

I guess I paid the price for being a little too cocky after i set up the first few controllers. Cheers!

I have the following models:
class Entity < ActiveRecord::Base
...
has_many :locations, :dependent => :destroy,
:include => :sites
has_many :sites, :through => :locations
class Site < ActiveRecord::Base
has_many :locations
has_many :entities, :through => :locations
class Location < ActiveRecord::Base
belongs_to :entities
belongs_to :sites
In views/entities/index.html.erb I have this:
<% if entity.locations.empty? -%>
<%= link_to ''Add Locations'',
new_entity_locations_path(entity) -%>
<% else -%>
<%= link_to ''Edit Locations'',
entity_locations_path(entity)
-%>
<% end -%>
And in entities_controller.rb I have this:
10 def index
11 @entities = Entity.find(:all)
12
13 respond_to do |format|
14 format.html # index.html.erb
15 format.xml { render :xml => @entities }
16 end
17 end
When I look at views/entities/index I get this error:
uninitialized constant Location::Sites
...
64: <% if entity.locations.empty? -%>
65: <%= link_to ''Add Locations'',
new_entity_locations_path(entity) -%>
66: <% else -%>
...
app/controllers/entities_controller.rb:13:in `index''
I am evidently overlooking something obvious but for the life of me I
cannot see what. Another pair of eyes is most welcome.

If I use the plural forms then I get this message instead, but at exactly the same places: uninitialized constant Location::Sites I cannot see what it is that I am doing wrong here. entity.locations is the collection of locations relating to entities, that might be empty, while location.site should be the the site related to a location in that collection. I cannot tell where this Sites is coming from. I have checked site.rb and the class name is defined as this: class Site < ActiveRecord::Base has_many :locations has_many :entities, :through => :locations SO, what is going on? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If so then why?Yes. it''s a problem because you''re saying ''when you load location, also load the association sites". But location doesn''t have an association called sites (it does have one called site) Fred --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
