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

\<% form\_for @wines, :url =\> { :action =\> ‘show’ } do |f| %\>  
The action name is ‘show’ not ‘Show’

The ‘show’ action is for displaying the details of one item, yet you  
have @wines (a collection) in your form\_for.

\<% form\_for @wine do |f| %\>

This syntax would take care of everything for showing the detail view  
via the ‘show’ action.

In your case it sounds like you might be trying to make a search form.  
If that’s the case you probably shouldn’t be using form\_for anyway, but  
rather form\_tag.

Have you read though the Rails Guide on form helpers?
