Rails - Jun 2006 - Framework question about FormHelper ...

Hello,

I don''t understand how formhelper works (In a Framework point of view)
...
For example if I use the chek_box formhelper

1/ check_box("puppy", "gooddog", {}, "yes",
"no") will call @puppy.gooddog
BUT, how it is possible since the check_box has only a string parameters 
not instance object ?

2/ if you create your own helper which generate html identically as the 
check_box("puppy", "gooddog", {}, "yes",
"no") do
( <input type="checkbox" id="puppy_gooddog"
name="puppy[gooddog]"
value="yes" />
    <input name="puppy[gooddog]" type="hidden"
value="no" />)

=>Why  you cannot  get the paramater value  in your controller  ?  
params[:puppy][:gooddog] never return yes ...


thanks
