I am very new to ruby, and trying to get auto complete / predictive text
working, but I am getting the error "undefined local variable or method
`providers'' "
Here is the first box in my view
[code]
<label for="">Provider:</label>
<div>
<%= text_field_with_auto_complete :orders, :provider,
{ :tabindex => 1,:size => 30, :maxlength => 100 },
{ :url => { :controller => :orders,
:action => :auto_complete_for_provider_name},
:indicator => ''ajax-prov-load-ind'',
:after_update_element =>
"function(element,value){$(''activation_customer'').enable();$(''activation_customer'').focus();}"
} -%>
<span style="display:none;"
id="ajax-prov-load-ind"><%= image_tag
''ajax-load-ind.gif'', :style =>
''vertical-align:middle;'' %></span> <a
href="#TB_inline?height=350&width=400&inlineId=add_provider&modal=true"
class="thickbox">Add Provider</a>
</div>[/code]
And here is the auto_complete_for_provider_name.rhtml, with the bold
line where it throws the error.
<ul>
[b]<% providers.each do |key, value| -%>[/b]
<li id="<%=h value -%>"><%=h key -%></li>
<% end -%>
</ul>
here is a snippit from orders controller,
def auto_complete_for_provider_name
@provider = params[:orders][:provider].downcase
@providers = Provider.call_provider_list_service(@provider)
render :partial => ''auto_complete_for_provider_name'',
:locals =>
{:providers => @providers}
end
end
[/code]

I am just lost. Can anyone tell me why I would get a undefined method

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:> I am just lost.

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.

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. You can read more about them here: http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html#M000610 http://api.rubyonrails.org/classes/ActionView/Helpers/JavaScriptMacrosHelper.html#M000576 Hallik Papa wrote:> William Pratt 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. >> > > This is working code in another page that I inherited to try and learn > Ruby.

Thank you. I didn''t know that a column in the table could be considered a method as well. That clears up so much.

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?
