Hi all,
I am teaching myself rails and I can''t figure out why the following
code does not work: ''say'' part works, but nothing shows up for
''get_new'' part.
Here is my chat_controller.rb file:
class ChatController < ApplicationController
def index
end
def say
@line = params[:say_so]
end
def get_new
end
end
---------------------------------------------------------------------------------------------------------------------
Here is my index.rhtml file:
<%= form_remote_tag :update => "put_here", :url => {:action
=> ''say''}
%>
<%= text_field_tag ''say_so'' %>
<p id="put_here"> </p>
<%= submit_tag ''Say'' %>
<%= end_form_tag %>
<%= periodically_call_remote :url => {:action =>
''get_new'' }, :update
=> ''put_there'', :frequency => 2.0 %>
<p id="put_there"> </p>
-----------------------------------------------------------------------------------------------------------------------
say.rhtml and get_new.rhtml files are simply:
<%= @line %>
-----------------------------------------------------------------------------------------------------------------------
