AWDWR (latest) searc example with REST

Rails
1

There’s an example in the book that presents a search form , listing
users
and their favorite languages below it. Using the search form text field
you
can filter the list by their favorite language.

I did the demo from the book using the same schema and it works.
However, I’m trying to implement this same thing in my app which uses
REST
controllers, and am running into an error when loading the search form.
The
error is:

ActiveRecord::RecordNotFound in PositionsController#show
Couldn’t find Position with ID=search_position

I’m assuming the issue is in the search action in the controller. The
list.rhtml should return all the positions. It all looks pretty
straight
forward.
In the controller:

def search
unless params[:search].blank?
@position_pages, @positions = paginate :positions,
:per_page => 10,
:order => order_from_params,
:conditions => Position.conditions_by_like(params[:search])
logger.info @positions.size
else
list
end

render :partial => 'search', :layout => false
end

I’m showing the get/show in the controller - though I’m not sure if or
why
it would intefere with the search action.
def show
@position = Position.find(params[:id])

respond_to do |format|
  format.html # show.rhtml
  format.xml  { render :xml => @position.to_xml }
end

end

I was having a problem like this recently. I believe it’s a problem in
your routing, because params[:search] is returning ‘search_position’
instead of the value you want. Have a look at the params that are being
received by your action when you call the URL.

Not entirely sure what I’m seeing in the log but this is the select
statement going out:
Parameters: {“action”=>“show”, “id”=>“search_position”,
“controller”=>“positions”}
e[4;36;1mUser Columns (0.000000)e[0m e[0;1mSHOW FIELDS FROM
userse[0m
e[4;35;1mUser Load (0.000000)e[0m e[0mSELECT * FROM users WHERE
(users.id = 11 ) LIMIT 1e[0m
e[4;36;1mPosition Columns (0.000000)e[0m e[0;1mSHOW FIELDS FROM
positionse[0m
e[4;35;1mPosition Load (0.000000)e[0m e[0mSELECT * FROM positions
WHERE
(positions.id = 0) e[0m

In the def index action I am filtering show by user. I guess at this
point
that is just an aside since /positions will return all the records of
that
user and I also can remove that condition. Which didn’t help.
What I see here is the odd statement "WHERE (positions.id = 0)

Not sure how the routing would effect things. Currently my routes.rb
are
fairly simple.

map.resources :users, :sessions, :companies
map.resources :positions, :member => {:description => :get}

else
@position = Position.find(params[:id])

What I’m seeing here ( i think) is that even though it should be
accessing
the search action in the controllers, it’s calling the get / show
action.
Hence the problem with the id issue.
Anyone ?
This might be a routing issue though right now nothing I’ve tried in
routes.rb is helping.

I took the whole code and moved it out of my restful controller, since I
can’t quite figure out how to make it work in there. However now that
it
has it’s own controller, I’m getting a nil error. Here is the code:

Controller code:
class PositionController < ApplicationController
def search
unless params[:search].blank?
@position_pages, @position = paginate(:positions,
:per_page => 10,
:order => order_from_params,
:conditions => Position.conditions(params[:search]))
logger.info @positions.size
else
list
end
render :partial => ‘search’, :layout => false
end
end

The search view
<%= start_form_tag(‘javascript:void%200’) %>

Listing users <%= text_field_tag 'search', @search %>

<%= observe_field :search,
:frequency => 0.5,
:update => ‘ajaxWrapper’,
:complete => “Element.hide(‘spinner’)”,
:before => “Element.show(‘spinner’)”,
:with => “‘search=’ +
encodeURIComponent(value)”,
:url => {:action=>‘search’, :only_path =>
false}
%>

<%= end_form_tag %>
<%= render :partial=>'search' %>

the _search partial

<%= javascript_include_tag :defaults %>

<% for position in @positions %> <----- this is where I’m getting the
nil
object. Makes no sense.

<% end %>

<%= link_to ‘Previous page’,
{ :page => @position_pages.current.previous } if
@position_pages.current.previous %>
<%= link_to ‘Next page’,
{ :page => @position_pages.current.next } if
@position_pages.current.next %>
