NameError, uninitialized constant States
I''m completely new to Ruby and Rails and could use some help resolving
an issue. I have a list method that is supposed to show the titles and
states(status) of requests, but I get an error from this piece of code:
<td><%= change.states.state %></td>
The error is:
c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:100:in
`const_missing'': uninitialized constant States
The states table contains an id and state field. The changes table
holds a foreign key named state_id that references the states table.
I want this code to simply display the text from the state field for
the specified change request.
Can anyone tell me what''s wrong?

In your Change model, do you have belongs_to :state ? From what I can tell, this is what you should have if your changes table has a fk field called state_id which links over to the states table''s id field. If these assumptions are correct, you would want to do <%change.state.state %> On 10/25/06, ryansv-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org <ryansv-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> > I''m completely new to Ruby and Rails and could use some help resolving > an issue.

Re: NameError, uninitialized constant States
I do have an entry in my Change model, but it says belongs_to:states. I also have an entry in the state model saying has_many:changes. When I try to use <%= change.state.state %> I get a no method found error, which is why I was trying <%= change.states.state %>. I have other tables with similar foreign key relationships and they all seem to work fine.

1) why do you post all your replies 3 times? :) 2) it has to be: belongs_to :state belongs_to are always singluar, has_many are always plural. like you would read it out loud: a change belongs to a state, and a state has many changes --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You should have "has_many :changes" in your State model (so it sounds like you have that part right), and "belongs_to :state" in your Change model (a State can have many Changes, but a Change belongs only to a single State). This will give you change.state.state in your controllers/views. The only other suggestion I would make would be to possibly change the name of your data column to "name" - state.state is kind of redundant, whereas state.name seems a little clearer. Comes down to personal preference and what makes sense to you, though. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

1) I think there''s a problem with my proxy server at work from where I''m posting. 2) The singular version worked. I guess I didn''t pay enough attention to the method parts.
