Rails
1

hi this is my htnl

<%= javascript_include_tag :defaults %> <%= form_tag nil, { :id => 'search_form' } %> <%= text_field 'recipe', 'name' %> <%= end_form_tag %>

<%= observe_form :search_form, :frequency => 0.5,
:update => ‘recipe’,
:url => { :action => ‘search_ajax’ } %>

below is the error i am getting
Action Controller: Exception caught

Showing room/search.html.erb where line #9 raised:

You have a nil object when you didn’t expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]

any idea

Also, always check your code, maybe even get your hands on a good
development environment:

    <%= observe_field(:search_name,:frequency =>

0.25,:ulr=>{:action=>‘search_ajax’},:with=>“prefix”,:update=>:room)%>

What’s an “ulr”? :slight_smile:
