Hello all,
I've just started to play around on Ruby and have read some tutorials,
books, and Why's guide. I do understand syntax of coding, or at least
that within the controller, but I have limited web programming
experience, so the view is giving me some problems. So here is the
issue,
I have a database of wines, that i'd like to be able to select by the
producer, and then those the associated wines. I thought this would
work, but I keep getting the 'Couldn't find Wine with ID=Show' error.
Any help and or pointers on this would be great. Thanks a ton!
from view:
<% form_for @wines, :url => { :action => 'Show' } do |f| %>
Producer: <%= collection_select(:wine,:desc,@wines,:id,:desc,
options ={:prompt => "Select a producer"}) %>
<%= submit_tag 'Submit' %>
<% end %>
from controller:
def show
@wine = Wine.find(params[:desc])
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @wine }
end
end
