Hello,  
I’m setting a checkbox values based on the return of a model field  
method. The way the method is set up - it only gets called when a  
checkbox value is set.

Here’s the model code:

```auto
  def within=(new_within)
     @within = new_within == "1" || new_within == true || new_within ==
'true' || new_within == 'on'
  end
```

I would like that method to be called even when the checkbox is not set.

Thanks for any help anyone can provide.

Clem C

Could you provide me the check box script in view?

you can put additional params in form\_tag

example :

\<% from\_tag bla…bla…, :within =\> true %\>

…

\<% end\_from\_tag %\>

I hope it can answer yours. it will be directly executed each time the  
form\_tag is run. What do you want this ‘def within’ is run for every  
time model is used or only in form\_tag?

Here’s the checkbox code:

\<input style=“height:13px;” id=“\<%= search\_obj %\>\_within” name=“\<%=  
search\_obj %\>[within]” type=“checkbox” \<%=  
!last\_search[:within].to\_s.blank? ? “checked=‘true’” : “” %\> value=“1”/\>

Also, here’s the form\_remote\_tag code:

\<%= form\_remote\_tag(:url =\> {:controller =\> ‘main’, :action =\> action},  
:html =\> { :id =\> “#{search\_obj}\_form”, :action =\> url\_for(:controller  
=\> ‘main’, :action =\> action) } ) %\>

I would like to have the def within to be run everytime the form\_tag is  
called.

I tried putting the :within =\> true in the form\_remote\_tag and had no  
results.

Thanks again for your help.
