Rails - Jan 2006 - How do you deal with non-model property form values

I have a User ActiveRecord model that has email and password properties.  I
want to build a login for that has a "remember me" option.  My view
looks
like this:

<% @page_title = "Login" -%>
<%= error_messages_for ''user'' %>
<%= form_tag %>
<table>
  <tr>
    <td align="right" width="1%"
nowrap="nowrap"><label class="required"
for="user_email">Email</label>:</td>
    <td><%= text_field("user", "email")
%></td>
  </tr>
  <tr>
    <td align="right" width="1%"
nowrap="nowrap"><label class="required"
for="user_password">Password</label>:</td>
    <td><%= password_field("user", "password")
%></td>
  </tr>
  <tr>
    <td align="right"><input type="checkbox"
id="remember"
name="remember"/></td>
    <td><label for="remember">Automatically log me in on
this
computer</label></td>
  </tr>
  <tr>
    <td>&nbsp;</td>
    <td><input type="submit" value="Login"
/></td>
  </tr>
</table>
<%= end_form_tag %>

I would like to use the check_box FormHelper method, but remember is not a
property of the User object, and I would rather not add it, since it
doesn''t
real make sense.  What''s the best way to handle this?

Hi Paul ~

You can pass it back in a separate hash.  So you could set name
extradata[remember], then access it separately from your user items in the
form.

params[:extradata][:remember]

Hope this helps,

Use check_box_tag() and an instance variable that isn''t  in your User
object. Like Ben says, it will still be accessible from params. In general,
all the form helpers with _tag endings are useful for instance variables
that are bookkeeping and not part of your real model.

Ok, so I did this in my index.rhtml:

<%= check_box("form","remember") %>

And then my controller method looks like this:

  def index
    if request.get?
      @user = User.new
    else
      @user = User.new(params[:user])
      logger.info(params[:form][:remember])
      flash[:notice] = "Invalid username/password"
    end
  end

when i submit the form, the form.remember value of 1 prints out, if I check
the remeber checkbox.  But when the form renders again, the checkbox is
unchecked.  Shouldn''t check_box handle setting the value of the
checkbox
correctly?  I also tried check_box_tag, but neither one sets the value of
the checkbox correctly.

That looks for an instance variable called @form with a method called 
''remember''.  What you probably want, judging by your
controller code, is:

<%= check_box_tag(''form[remember]'',
params[:form][:remember]) %>

And then remember to default it on the first time in your action.

Yeah, I just set it to do this:

<%= check_box_tag("remember",1,params[:remember]) %>

I was using :form because that was Ben''s suggestion (he actually
suggested
using :extradata).  That seems unnecessary.  So I removed that hand modified
the controller to just call params[:remember].

Thanks for your help everyone
