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.

start\_form\_tag was removed from rails over a year ago. Use form\_tag  
instead.

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 %\>

\<% end %\>
