I am trying to figure how to break up a Get into 2 seperate views. Scenario, user goes to index page and sees list of their posts with links to show, edit, destroy. Cool and working well. However in the show portion there is not enough room to display all the information. So in the show.rhtml page I have 90% of the information, then I want to put a link at the bottom to take them to the rest of the post information. Not sure how to do this restful proper. TIA Stuart
I'm trying to creating a route for this option. I have map.resources :positions, :collection => {:description => :show}
I believe that I need to create an action in the positions controller called description and then the helper url , should be description_position_path. However I'm getting an exception:
NoMethodError in Positions#show Showing app/views/positions/show.rhtml where line #73 raised: You have a nil object when you didn't expect it! The error occurred while evaluating nil.to_sym
Not sure if this is the right approach and i'm doing something wrong or this is the wrong approach completely. Stuart
I guess it's getting closer to figuring this out but I can still use some help. Trying to create an action in my restful controller so I can display more "show" information.
In my routes.rb - map.resources :positions, :collection => {:description => :get}
In the "show.rhtml" , I've added a link to see the additonal information - <%= link_to 'Show', description_positions_path %>
In the action Description - def description @position = Position.find(params[:id]) respond_to do |format| format.html format.xml {render :xml => @position.to_xml } end end
Leaving it like this allow me to load the first show page but when I hit the description link - I get Couldn't find Position without an ID
yet if I go back to my link and do <%= link_to 'Show', description_positions_path(position) %> Then it won't load the show.rhtml and gives me the error of undefined variable or method.
Anyone help ? Stuart
Bump ...
Don't be mad.
use :member
map.resources :positions, :member => {:description => :get}
and:
<%= link_to 'Show', description_positions_path(position) %>
use :member
map.resources :positions, :member => {:description => :get}
and:
<%= link_to ‘Show’, description_positions_path(position) %>
Nope, when I try to do this I get NameError in Positions#show Showing app/views/positions/show.rhtml where line #73 raised: undefined local variable or method `position' for #<#<Class:0x6483738>:0x6482c40>
I don't get it , I've read the documentation 12x now so it looks like this would work.

But this link does work: <%= link_to "Preview Description", :controller => 'positions', :action => 'description', :id => @position.id %>
And gives me a url of /positions/22;description , which I think looks right ? Stuart
sorry, I believe it is singular:
<%= link_to 'Show', description_position_path(position) %>
Nope, dont be sorry. Actually the plural version renders a path but without an id produce a "stack too deep" error, with (position) it returns the same no method error.

Clearly, I’m still learning how this stuff works, too. I just looked at my links and I actually don’t use the named routes for this sort of example.
We’re all still learning this stuff :). However I think that the way I crafted the link is acceptable. I did find it on one of the restful pages.
