Help with JQuery autocomplete in rails3
I'm having difficulty setting up JQuery Autocomplete with Rails3. I don't get any errors, it just behaves like regular text box.
Here is what I have done:
First I installed autocomplete as explained here: http://github.com/crowdint/rails3-jquery开发者_如何学Go-autocomplete#readme
I have a model class which contains the model which will be in the lookup:
class NdbFoodDesController < ApplicationController
autocomplete :ndb_no, :long_desc
... some other functions
end
Then I added the function in the routes file:
resources :ndb_food_des do
get :autocomplete_ndb_no_long_desc, :on => :collection
end
Then in the view form I have added these lines:
<% f.fields_for :ingredients_recipes do |rif| %>
<% javascript_include_tag "autocomplete-rails.js" %>
<td>
<input type="text" autocomplete="/ndb_food_des/autocomplete_ndb_no_long_desc" id_element="#ndb_no">
</td>
<td>
<%= rif.autocomplete_field :long_desc, autocomplete_ndb_no_long_desc_ndb_food_des_path %>
</td>
<% end %>
Is there something I'm doing wrong?
- Javascript include tags must be loaded in the html hader (in your layout file)
- autocomplete_tag doesnt work, use text_field instead
Don't forget that you also need jquery installed since they are not included in rails, see http://asciicasts.com/episodes/205-unobtrusive-javascript for reference and an alternative search method.
If it still doesn't work check the output of the server-console, usually it tells you what doesn't fit.
A warning to new readers on this.. rails3-jquery-autocomplete (1.0.10) only supports autocomplete_field_tag. Older versions (0.6.0 was the default used in the rails3-jquery-autocomplete-app) support both. Be sure to check the version of the gem you are using.
