undefined method `start_form_tag'

I tried to generate a form using the Rails "start_form_tag", but got
the error message "undefined method `start_form_tag' for
#<ActionView::Base:0x47b4c70>". What could be missing here. Thanks for
help.

what is the version of Rails you are using?

start_form_tag was removed from rails over a year ago. Use form_tag
instead.

thanks!

If only "form_tag" is needed, how can one know where is the end of the
form? Rails seems to evolve so fast that a book from a year ago is
useless. Where can I get the update info of Rails? Thanks for help!

it's a helper that takes a code block
<%= form_tag '/path' do %>
  <!-- insert your form here -->
<% end %>
