Ok so I am making a directory, the flow of the directory should be category to state to county to city to zip. I cant get it to work so that when you click on a certain category it links to you all the states it has. so far this is what i have.
routes.rb
map.resources :categories, :has_many => :states map.resources :states, :has_many => :counties ...........
So they start off in the show action of the categories controller which is
categories_controller.rb
def show @categories = Category.find(:all) respond_to do |format| format.html # index.html.erb format.xml { render :xml => @categories } end end
here is my show view for categories
show.html.erb
<h1>Listing categories</h1> <table> <% for category in @categories %> <tr> <td> <%= link_to category.title, state_path(@state) %></td> </tr> <% end %> </table>
here is my states controller
states_controller.rb
def index @states = @category.states respond_to do |format| format.html # index.html.erb format.xml { render :xml => @states } end end
and here is my index view for states
index.html.erb
<h1>Listing States</h1> <table> <% for states in @categories.states %> <tr> <td><%= link_to state.title, county_path(@county)%></td> </tr> <% end %> </table>
now I can get to the categories view and see all the categories but when I click on a specific category to go to show all the states it has it throws a error. Any help would be greatly appreciated, thnks in advance.
