This time i read scaffold tutorial very  carefully and finally try to
generate a form without using the scaffold(just used a controller and
view ).what i have done till now ,is as follow.Using rails 3.0.7.

                                 "rails generate controller posts
index"

  1) post_controller.rb

  class PostsController < ApplicationController
  def index
  @post=Post.new
  end
  def create
  @post = Post.new(params[:post])
  respond_to do |format|
  end
  end
  end

2)index.html.erb

 <h1>Posts#index</h1>
<p>Find me in app/views/posts/index.html.erb</p>
<%= link_to 'New Post', new_post_path%>
<%= form_for(@post) do |f| %>
 <div class="field">
    <%= f.label :name %><br />
    <%= f.text_field :name %>
  </div>
  <div class="field">
    <%= f.label :title %><br />
    <%= f.text_field :title %>
  </div>
  <div class="field">
    <%= f.label :content %><br />
    <%= f.text_area :content %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

                             i didnt create any model because i just
want to create a simple form first.so when i brower to "localhost:3000/
posts/index", it says

 "uninitialized constant PostsController::Post

Please somebody help to resolve it

Thanks
