Rails - Apr 2008 - form_for question

I have a following snippt to make a form.


<% form_for :post, @post, :url => { :action => "create" } do
|f| -%>

<%- end ->


What does ":post" and "@post" do respectively?

If my understanding is correct, @post is there because I set "@post
Post.new" in the action. But I don''t know what ":post "
is for.

:post is the parameter that will be symbolic to f

another form format is

<% form_tag :action => "create" do %>

<%= text_field "post", "name" %>
OR
<%= text_field :post, "name" %>

<% end %>
<% end_tag %>

BUT HERE
> <% form_for :post, @post, :url => { :action => "create"
} do |f| -%>
> 
> <%- end ->
<%= f.text_field "name" %>

in your controller the input parameter will be
params[:posts] and its hash.
params[:posts]["name"]
params[:posts]["id"]

Like that.
