<p>i'm having a problem to create a text_field without a method association. Maybe i even don't need it :-)</p>

<p>I have two radio_buttons associated to the same method:</p>

<pre><code>&lt;%= radio_button :comment, :author, "anonymous" %&gt; Anonymous &lt;br&gt;
&lt;%= radio_button :comment, :author, "real_name" %&gt; Name &lt;br&gt;
</code></pre>

<p>What i would like to do is to have an text_field which when the user click on the radio_button "real_name" i can verify the value in this new text_field. </p>

<p>Basically my Controller would be something like:</p>

<p>@comment = Comment.new(params[:comment])</p>

<p>if @comment.author == "real_name"
 @comment.author = "value-from-the-new-textfield
end</p>

<p>There is any way to do it?</p>

<p>Regards,</p>

<p>Victor</p>

If you want to generate a text_field without an associated object/method, use
```
text_field_tag
```
