How is your Order class setup? Does it have a provider method? In other words, does this return true in script/console: Order.new.respond\_to? provider Hallik Papa wrote: ---

If you are wanting something with the same functionality that is not designed around a specific object, you can use text\_field\_tag along with auto\_complete\_field. William Pratt wrote: ---

Ok, here is the basic deal. The code you are using requires your Order object to have a provider method. This would be either a column in the table, an association, or possible a custom method. Based on the method you are using for autocomplete, you don’t want to use text\_field\_with\_auto\_complete, you need to use a combination of text\_field\_tag and auto\_complete\_field.

Now you can enter Ruby expressions in the context of your Rails environment: > > Order.new.respond\_to? :provider =\> false (note that respond\_to? takes a symbol, so you need ":provider", not "provider") Learn the console. Love it. :~) HTH ---

That was my bad. I should have explained the console better. Btw, respond\_to? will attempt to convert it’s argument to a symbol, so anything responding to to\_sym should work: > > User.new.respond\_to? ‘login’ =\> true > > User.new.respond\_to? :login =\> true -Bill Bob Showalter wrote: ---

Right, but    User.new.respond\_to? login isn't correct, and that's what he was using. ---
