I’ve been working with a tutorial over on [railsforum.com](http://railsforum.com) on creating  
variable numbers of models in one form.

I have a script model that has one or many script\_metadatas.

My code is the following:

1. 
# scripts\_controller.rb
2. def new
3. 

```
@script = Script.new

```

4. 

```
@script.script_metadatas.build

```

5. end
6. 
7. def create3
8. 

```
@script = Script.new(params[:script])

```

9. 

```
params[:script_metadatas].each_value { |script_metadata|

```

@script.script\_metadatas.build(script\_metadata) }  
10. if @script.save  
11. redirect\_to :action =\> ‘index’  
12. else  
13. render :action =\> ‘new’  
14. end  
15. end  
16.  
17. def add\_script\_metadata  
18. @script\_metadata = Script\_metadata.new  
19. end  
20.  
21. # scripts/new.rhtml  
22. \<% form\_for :script, :url =\> { :action =\> ‘create3’ } do |f| %\>  
23.

Description: \<%= f.text\_field :description %\>

  
24. 
## Script\_metadatas
  
25. 
  
26. \<% @script.script\_metadatas.each\_with\_index do |script\_metadata,  
index| %\>  
27. \<%= render :partial =\> ‘script\_metadata\_fields’, :locals =\> {  
:script\_metadata =\> script\_metadata, :index =\> index } %\>  
28. \<% end %\>  
29. 
  
30. \<%= render :partial =\> ‘add\_script\_metadata\_link’, :locals =\> {  
:index =\> @script.script\_metadatas.size } %\>  
31. 

\<%= submit\_tag ‘Create Script’ %\>

  
32. \<% end %\>  
33.  
34. #scripts/\_script\_metadata\_fields.rhtml  
35. 
  
36. \<% fields\_for “script\_metadatas[#{index}]”, script\_metadata do |f|  
%\>  
37. 

38. \<%= f.text\_field :meta\_key %\>  
39. \<%= link\_to\_remote ‘remove’, :url =\> { :action =\>  
‘remove\_script\_metadata’, :index =\> index } %\>  
40.

  
41. \<% end %\>  
42. 
  
43.  
44. # scripts/\_add\_script\_metadata.rjs  
45. 
  
46. \<%= link\_to\_remote ‘Add Another Script\_metadata’, :url =\> {  
:action =\> ‘add\_script\_metadata’, :index =\> index } %\>  
47. 
  
48.  
49. # scripts/add\_script\_metadata.rjs  
50. page.insert\_html :bottom, :script\_metadatas, :partial =\>  
‘script\_metadata\_fields’,  
51. :locals =\> { :script\_metadata =\> @script\_metadata, :index =\>  
params[:index] }  
52.  
53. page.replace :add\_script\_metadata\_link, :partial =\>  
‘add\_script\_metadata\_link’, :locals =\> { :index =\> (params[:index].to\_i

- 
  1. }

  1. 
  2. 
# scripts/remove\_script\_metadata.rjs
  3. page[“script\_metadata\_#{params[:index]}”].remove

The problem being, when I click on the button that calls  
‘add\_script\_metadata.rjs’ nothing happens and I don’t get another row to  
input another set of metadata.

Can anyone suggest why this is?

This is the kinda problem where the right debugging tool will pay  
huge dividends.

(if you haven’t) pickup firebug[1] - using it you can watch the http  
request/response; then tail your development log. These 2 bits of  
info will tell you more symptoms. You’ll likely solve your problem,  
if not you’ll have more info for us to help you out.

Thanks for the reply, Jodi.

I’ve just downloaded and installed the firebug plugin. Having never used  
it could you point me in the right direction as to under which tab I  
should be looking?

P.S. The script is now working as it should - in IE only…

I have one line for script name, description, path.

Then underneath it one line for metadata name and metadata value with an  
‘add another’ button to add more metadata name/value pairs.

When multiple name/value pairs are input, IE stores all of them in the  
database. Wheras Firefox only stores the very first pair. Can you  
suggest why this is?
