Auto_complete_with_index_for


#1

I have a crude hack to allow auto_complete to work with indexed text
fields. I needed it for a timecard entry form with an arbtirary
number of records which can be added/changed/delete willy-nilly by
users. One of the fields is a perfect candidate for autocomplete
since it references a database object with a large number of choices
and long descriptions. Using a select list is extremely ugly in this
case.

I copied the code for text_field_with_auto_complete out of

/usr/local/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_view/helpers/java_script_macros_helper.rb

and hacked it, putting the result in

app/helpers/application_helper.rb

as text_field_with_index_auto_complete. All it does differently is
not output the index in the name of the method to be called.

I copied the code for auto_complete_for out of

/usr/local/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/macros/auto_complete.rb

and pasted it right back in as auto_complete_with_index_for. It just
ignores the index in the parameter. Everything else is the same.

I will probably submit a bug report and a patch eventually, but in the
meantime, I would like to know if I can put the new
auto_complete_with_index_for somewhere local to my application, or
does it have to live in the rails source?

Thanks!

Hey, answered my own question. I copied the relevant bits of
/usr/local/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/macros/auto_complete.rb
into environment.rb. Cool beans.

If anyone wants magic auto completion for indexed fields (a la render
:partial) then let me know.
