Text_field_with_auto_complete in a component?

Rails
1

Maybe this one is just way too esoteric to matter all that much, but
it’s bugging me. I’m doing a prototype for demonstration on Thursday,
and making heavy use of components (scalability/performance not a
concern, but rapid development of small contained pieces is). Here’s
my problem - it looks like a text_field_with_auto_complete doesn’t work
in a component, because of the changing controller.

I’ve got main/index.rhtml, from which I render component/index.rhtml.

In component/index.rhtml I have a text_field_with_auto_complete :person,
:name

When it runs, however, I get an error because Rails looks for the
auto_complete_for_person_name method on the main controller, rather
than the component controller. I mean, I can see why it does that,
I’m just trying to figure out a way around it. Best I can tell there’s
no :controller=>“component” option I can slap on the text field.

The strange thing is that if I do an Ajax update on the
component/index.rhtml page (sort of “portlet” style where just the div
updates), then the text_field_with_auto_complete works fine. So
something about the Ajax update changes the context under which the text
field is rendering, so that it knows it is now in the component/
controller instead of main/.

Anybody got any suggestions?

Pass :url in the rightmost options parameter:

def text_field_with_auto_complete(object, method, tag_options = {},
completion_options = {})

like this:

<%= text_field_with_auto_complete :user, :name, {}, :url => { … }
%>

That’s a regular :url option, you may assign a named route as well for
example.
