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 %\> &nbsp;&nbsp;\<!-- insert your form here --\> \<% end %\> check out the API (you can also download a nice version from [http://www.railsbrain.com/](http://www.railsbrain.com/)
