Title Body

I'm writing a form which is dealing with multiple models. Some examples of how to do this use ActionView::Helpers::FormHelper::label , and some use ActionView::Helpers::FormTagHelper::label_tag , and I don't really understand the difference. In my particular case, both seem to result in the same output: <% form_for :post, :url => { :action => 'create' } do %> <%= label_tag 'post_type' %> <%= text_field :post, :post_type %> <%= label :post, :parent_post_id %> <%= text_field :post, :parent_post_id %> ... Renders: <label for="post_type">Post type</label> <input id="post_post_type" name="post[post_type]" size="30" type="text" /> <label for="post_parent_post_id">Parent post</label> <input id="post_parent_post_id" name="post[parent_post_id]" size="30" type="text" /> The label helper would seem to be more useful, because presumably there are some extra things it can do because it knows the model and property it's labelling, but I can't find anything to back that up. Is there a practical difference between the two? When should I use one helper instead of the other?
