A little detail would help (ie what doesn’t work if you just bung a
link_to_remote in your form ?)

why not use form_remote_for ?
gives you an ajax call to and the form_for stuff

anyway, please give us more details, what you want to
do, and/or what exactly your problem is.

for link_to_remote it doesn’t matter, if it’s within a form
or not and it’ll display & work as everywhere else.
so if you have problems, they’re specific to your code.

The problem here is that the id of your username textfield isn’t
username (it will be something like user_username). Check your html.

Hi
Actually i work user avilability check.ie) the newuser choose the
username and check whether his username already available or not.

my form looks:-

 <% form_for :user,@user, :url => {:controller => 'account', :action

=> ‘signup_new’} do |f| %>

Choose Username : <%= f.text_field 'username', :class => "text-n", :tabindex => 2 %> <% link_to_remote "check",url => {:controller => 'account',:action =>'Available'},:with => "'user_name='+$F('username')",:complete => 'alert(request.responseText)'

In controller:

def Available
@u= User.find_by_username(params[:user_name])
if @u !=nil
if request.xhr?

      render(:text => "User Name Already exist" , :layout => false)
    else
     render(:text => "User Name doesn't exist ",:layout => false )

  end
end

end

 If i use form_tag it works fine (ie.Alert box popup with ajax

response message)…If I use form_for_remote,form_remote_for the ajax
call doesn’t made this is my exact problem. I need use the form which
involves model also.
