Ruby on Rails form_remote_tag missing template

Question

I'm using form_remote_tag(:url => {:controller => "home", :action => "search"}, :update => "mydiv"). When I click submit on the form "mydiv" is populated with the error "Template is missing. Missing template home/search.erb in view path app/views". I've tried multiple render options in def search, but they all result in the same error.

It looks like the search method is trying to use it's default render even though I'm specifying what I want.

I've tried:
render 'index'
render :text => 'Return this from my method!'

Is my url incorrect? Is it not submitting back to my home controller's search method?

Answer 1

Try

render :action => 'index'

this will use "index.rhtml" or "index.html.erb".

Answer 2

The form_remote_tag needs prototype to function. Make sure you are including the :defaults for your javascript libraries namely prototype.

<%= javascript_include_tag :defaults %>

Answer 3

I will try to explain why it said search.erb is not found, lets take create action for a some model, if there is some error in my create action they it will throw missing template create.html.erb file, since you have some error in your create action rails will try to render the create.html.erb in the page. Hope I explained it clearly.

In an ajax action you can't use redirect_to or render options directly. try using this in your search action

render :update do |page|
  page.replace_html "ur_div_id","partial"
end
