I have crated controller classified class ClassifiedController < ApplicationController def list @classifieds = Classified.find(:all) end def show @classified = Classified.find(params[:id]) end def new @classified=Classified.new end def create end def edit end def update end def delete end

end and created classified/new.rhtml

start_form_tag has been deprecated and subsequently removed. use form_tag instead:

<% form_tag :action => :foo, ... do %>     form elements here <% end>

While doing a tutorial on tutorialpoint, I had the same problem! I made the change, but I get another error :

NoMethodError in Book#new

Showing app/views/book/new.rhtml where line #4 raised:

undefined method `title' for #<Book id: nil, created_at: nil, updated_at: nil> Extracted source (around line #4):

1: <h1>Add new book</h1> 2: <%= form_tag :action => 'create' %> 3: <p><label for="book_title">Title</label>: 4: <%= text_field 'book', 'title' %></p> 5: <p><label for="book_price">Price</label>: 6: <%= text_field 'book', 'price' %></p> 7: <p><label for="book_subject">Subject</label>:

here is the new.rhtml file:

<h1>Add new book</h1> <%= form_tag :action => 'create' %> <p><label for="book_title">Title</label>: <%= text_field 'book', 'title' %></p> <p><label for="book_price">Price</label>: <%= text_field 'book', 'price' %></p> <p><label for="book_subject">Subject</label>: <%= collection_select(:book,:subject_id,@subjects,:id,:name) %></p> <p><label for="book_description">Description</label><br/> <%= text_area 'book', 'description' %></p> <%= submit_tag "Create" %> <%= end_form_tag %> <%= link_to 'Back', {:action => 'list'} %>

thanx indeed for your help!
