I have a table that is defined as has\_many and the child table is  
defined as has\_one. I can create new children with ease and do almost  
everything else I want to do with it except for one thing. I have a  
form and within that form I have text boxes to update a column in the  
the children objects (multiple). In that same form I want to also  
update columns and attributes of the parent. Does anyone have an  
example to have a single button form that updates multiple tables/  
models? Or can you point me to the right tutorial? Agile Web  
Development mentions passing an array to the update method but there  
is no example.

Thanks

Andrew

To clarify here is some code that I have tried:

My controller has this action:

def update\_radio\_buttons  
@field = Field.find(params[:id])  
@field.update\_attributes(:field\_text =\> params[:field\_text],  
:required =\> params[:required])  
for @value in @field.values  
value\_text = “:valuetext\_#{@value.id}”  
@temp = params[value\_text]  
@value.update\_attribute(:value\_text =\> @temp)  
end  
# more stuff here  
end

view:

my view looks sort of like this (i condensed the partials and some of  
the other stuff going on on the page to save some space here)

\<%= form\_remote\_tag( :update =\> ‘FieldDesignArea’,  
:url =\> { :action =\> ‘update\_radio\_buttons’, :id =\>  
@field.id }) %\>  
Field:  
  
\<%= text\_area\_tag(:field\_text, @field.field\_text) %\>  
  
  
Values:

  
\<% for @value in @field.values %\>  

  

 \<% end %\> 

The error that I get when I run this code after making a change is  
the following:

wrong number of arguments (1 for 2)

and the parameters look like this:

Parameters: {“commit”=\>“Udate”, “valuetext\_58”=\>“huh”,  
“valuetext\_71”=\>“Choice”, “id”=\>“106”, “required”=\>“1”, “\_”=\>"",  
“field\_text”=\>“New Field Is here”}

So that is in a nut shell what I am trying to do. Any help would be  
greatly appreciated.

I copied a directory of views and noticed that the  
Scaffold.CSS stylesheet didn’t add to my pages. Is  
there a way to manually link to a style sheet?
