Rails - Sep 2007 - What is difference between form_for and form_tag?

Hello!

The many answers of this question are not appropriated for me.
What is the BIG difference between form_for and form_tag?

In several web pages, i read like below...
form_for method is used for specificated wrapped model object,
and form_tag is just output the <form> tag.
It''s not clear to me...

Isn''t it equal that source using form_for or form_tag?

Please, any feedback to me.
Thanks!

Rucy.

You would use form_for for a specific model when you want to create a 
new row, like this


<% form_for :person, @person, :url => { :action => "update" }
do |f| %>

then in here you can use the f object to create input field.

    First name: <%= f.text_field :first_name %>
    Last name : <%= f.text_field :last_name %>
    Biography : <%= f.text_area :biography %>

<% end %>

Form_tag create basically just <form ...></form>, can be used to
create
multi form or whatever speciale thing you want to create.


<% form_tag ''/posts'' do -%>
  <%= text_field_tag "post", "first_name" %>
<% end -%>
