There''s some cut-and-paste involved from previous, sorta working
versions. I''m looking at line #29, and don''t understand it.
What does tag.name mean? The current Tag object? the name field for
that object? Something else?
I''m getting the following error:
NoMethodError in Feeds#show
Showing app/views/feeds/show.rhtml where line #29 raised:
undefined method `name'' for #<Tag:0xb7179e4c
@attributes={"tag"=>"tag
one", "id"=>"1"}>
Extracted source (around line #29):
26: (None)<p>
27: <% else %>
28: <% for tag in @feed.tags %>
29: <%= tag.name %>
30: <%= link_to ''Remove'', { :action =>
''remove_tag'',
31: :id => @feed, :which_tag => tag.id },
32: :confirm => ''Are you sure?'', :post => true %>
http://localhost:3000/feeds/show/1
The code is at:
http://strawr.googlecode.com/svn/trunk/app/views/feeds/show.rhtml
Thanks,
Thufir

Hi, tag object doesn''t have attribute called name and it doesn''t have name method so you must be getting error you might replace tag.name with tag.tag Thufir wrote:> There''s some cut-and-paste involved from previous, sorta working > versions.

I wish that I''d simply written the view, but that probably wasn''t the case :( -Thufir --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

That view for the has_many_through is working. However, I would like to add CRUD functionality: thufir@arrakis ~/strawr $ thufir@arrakis ~/strawr $ tail app/controllers/feeds_controller.rb -n 20 def add_some_tags @feed = Feed.find(params[:id]) @unused_tags Tag.find(:all) - @feed.tags if @unused_tags.any? @tags_to_add = @unused_tags.select { |tag| (@params[''tag''+tag.id.to_s][''checked''] == ''1'')} @tags_to_add.each { |tag| @feed.tags << Tag.find_or_create_by_tag(params[:which_tag])} end if @tags_to_add.any? and @feed.save flash[:notice] = ''Tags have been added!'' end redirect_to :action => ''show'', :id => @feed end end thufir@arrakis ~/strawr $ In the show I need to add a form to call this method? thanks, Thufir --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

That view for the > has_many_through is working.I forgot that I had installed a plug-in. Ok, my show does now display the "add tag" button (but only if there are tags not associated with that feed.) However, clicking on the button results in: ActiveRecord::HasManyThroughCantAssociateNewRecords in FeedsController#add_some_tags Cannot associate new records through ''Feed#memberships'' on ''#''. Both records must have an id in order to create the has_many :through record associating them. RAILS_ROOT: ./script/../config/.. The feeds/show.rhtml is at http://strawr.googlecode.com/svn/trunk/app/views/feeds/show.rhtml I fixed the naming conventions; the model''s look good; the streamlined plugin has now given a "remove" CRUD interface, which is nice, and works. Is it because I''m using deprecated code in the controller, perhaps? All data was entered during the migration (from db/migrate/00#_<foo>.rb and so forth). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
