Weird problem with RUBY and AJAX (form_remote_tag and submit_tag)
Hello,
I am trying to implement the depot sample application of "Agile
programming with rails", everrithing goes good until came to AJAX
stuff,
When I changed the button_to for submit_tag I have no HTML code
generated for invoking the action using AJAX, I read the
troubleshooting section and everything is OK, any Idea of what could be
happening?
The code in index.rhml is
<% form_remote_tag :url => {:action => :add_to_cart, :id =>
product
} do %>
<%= submit_tag "Add to Cart" %>
<% end %>
and the resulting form has nothing, just a couple of blank lines in the
place that should show the button.
Thank you

In general, you use <% for "figuring things out", like setting a variable to the result of a calculation, and you use <%= for lines where you want the stuff in there to create some output into the html stream. jp -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I stopped reading when I "saw" the missing You are using form_remote_tag the way one would use form_for. form_remote_tag doesn''t use a do/end block. Try form_remote_for. jp -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Otherwise everything inside your form block will dissapear. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
