Hello, i have a problem, had a table called news and other called
news_images,
the first é for save news and other for save url for images associated
with news.
Make migrations for each table manual and db:migrate after that i run
scaffold for news, and generate model for news_image... put has_many
and belongs_to in file_column on news_image model and ok.... when i
try access page for new News i get this error:
ActionController::RoutingError in News#new
news_url failed to generate from
{:action=>"show", :controller=>"news"} - you may have
ambiguous
routes, or you may need to supply additional parameters for this
route. content_url has the following required parameters:
["news", :id] - are they all satisfied?
Extracted source (around line #5):
2:
3: <%= error_messages_for :news %>
4:
5: <% form_for(@news) do |f| %>
I don''t understand why, i don''t had any other route with same
name in
routes.rb, i can''t had tables with names like news?
Obrigado .

You aren''t defining @news in your edit method definition in your news controller On Jan 20, 2008 9:05 PM, Bregor <pipopolam-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> > Hello all! > > I still don''t understand, what to do in news/edit.html.erb > > when I try to get /news/1/edit (news with this id exists, of course) i > see following: > > > NoMethodError in News#edit > > Showing news/edit.html.erb where line #9 raised: > > You have a nil object when you didn''t expect it! > The error occurred while evaluating nil.to_sym > > Extracted source (around line #9): > > 6: <div class="errors"> > 7: <%= error_messages_for :news %> > 8: </div> > 9: <% form_for(@news) do |f| %> > > > > link to edit looks like: <%= link_to ''Edit'', > edit_news_instance_path(news), :class=>"button long" %> > > In routes.rb: > > map.resources :news, :singular => ''news_instance'' > > All other are works, except edit... > > > >-- Ryan Bigg http://www.frozenplague.net Feel free to add me to MSN and/or GTalk as this email. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Actually the problem is not that @news is not defined in the edit action (it might be an additional problem) The way I see it, he :singular option is only used to create the the url-generation methods for the resource (e.g. edit_news_instance_path, etc.) This option however is not used by the form_for @news call to deduct the name of the url-generation-method. It just gets the singular class name of the News class from the inflections, hence instead of edit_news_instance_path, edit_news_path is called, which, of course, does not exist. A workaround might be specifying the :url option in form_for, although I''ve had trouble with this, too, at least when using namespaced resources. I hope this helps On 20 Jan., 23:57, "Ryan Bigg" <radarliste...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> You aren''t defining @news in your edit method definition in your news > controller > > On Jan 20, 2008 9:05 PM, Bregor <pipopo...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > > > > > > Hello all! > > > I still don''t understand, what to do in news/edit.html.erb > > > when I try to get /news/1/edit (news with this id exists, of course) i > > see following: > > > NoMethodError in News#edit > > > Showing news/edit.html.erb where line #9 raised: > > > You have a nil object when you didn''t expect it! > > The error occurred while evaluating nil.to_sym > > > Extracted source (around line #9): > > > 6: <div class="errors"> > > 7: <%= error_messages_for :news %> > > 8: </div> > > 9: <% form_for(@news) do |f| %> > > > link to edit looks like: <%= link_to ''Edit'', > > edit_news_instance_path(news), :class=>"button long" %> > > > In routes.rb: > > > map.resources :news, :singular => ''news_instance'' > > > All other are works, except edit... > > -- > Ryan Bigghttp://www.frozenplague.net > Feel free to add me to MSN and/or GTalk as this email.--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
