Routing problem, I think

Rails
1

I’ve got a Rails app that brings up a Home page, which includes a
Vendor link. Clicking on that link I get
===========Web page start ========
NameError in VendorController#index
uninitialized constant VendorController
RAILS_ROOT: K:/_Projects/Ruby/_Rails_Apps/_EIMS/RTS
Application Trace | Framework Trace | Full Trace
Request
Parameters:
None
Show session dump
Response
Headers:
{“Content-Type”=>“”,
“Cache-Control”=>“no-cache”}
===========Web page end ========
I start up with http://localhost:3000, which references config
\routes.rb that contains (sans comments):
ActionController::Routing::Routes.draw do |map|
map.resources :vendor
map.root :controller => “home”, :action => “index”
map.connect ‘:controller/:action/:id’
map.connect ‘:controller/:action/:id.:format’
end

That combination brings up a webpage that includes a link named
Vendor, which is generated by the collective effect of:
• app\controllers\ app\controllers
class HomeController < ApplicationController
layout ‘standard’
def list
end
end
• app\views\home\ index.html.erb

<%= link_to ‘Vendor’, :controller=>‘vendor’, :action=>‘index’ %>
 

My machine is configured with:
Rails 2.3.5
Ruby 1.8.6
WinXP-Pro/SP3
Firefox 3.6
MySQL 5.0.37-community-nt
Mongrel

What’s in vendor_controller.rb ?

I think it is looking for vendors_controller.rb

The controller is always the plural of the model, unless specified.

Renaming your vendor_controller.rb file to vendors_controller.rb should
work.

Hi Frederick,

Thanks for looking into my problem. I trying hard to come up to speed
on Rails. I think my Ruby’s now adequate.

Best wishes,

What’s in vendor_controller.rb ?

\app\controllers\vendors_controller.rb

class VendorsController < ApplicationController

GET /vendors

GET /vendors.xml

def index
@vendors = Vendor.all

respond_to do |format|
  format.html # index.html.erb
  format.xml  { render :xml => @vendors }
end

end

GET /vendors/1

GET /vendors/1.xml

def show
@vendor = Vendor.find(params[:id])

respond_to do |format|

  format.xml  { render :xml => @vendor }
end

end

@vendor = Vendor.find(params[:id])
end

POST /vendors

def create
@vendor = Vendor.new(params[:vendor])

respond_to do |format|
  if @vendor.save
    flash[:notice] = 'Vendor was successfully created.'
    format.html { redirect_to(@vendor) }
    format.xml  { render :xml => @vendor, :status

=> :created, :location => @vendor }
else
format.html { render :action => “new” }
format.xml { render :xml => @vendor.errors, :status
=> :unprocessable_entity }
end
end
end

PUT /vendors/1

PUT /vendors/1.xml

def update
@vendor = Vendor.find(params[:id])

respond_to do |format|
  if @vendor.update_attributes(params[:vendor])
    flash[:notice] = 'Vendor was successfully updated.'
    format.html { redirect_to(@vendor) }
    format.xml  { head :ok }
  else
    format.html { render :action => "edit" }
    format.xml  { render :xml => @vendor.errors, :status

=> :unprocessable_entity }
end
end
end

DELETE /vendors/1

DELETE /vendors/1.xml

def destroy
@vendor = Vendor.find(params[:id])
@vendor.destroy

respond_to do |format|
  format.html { redirect_to(vendors_url) }
  format.xml  { head :ok }
end

end
end

Hi All,

I got the links working. I was just puttering around and all of a
sudden I got them working. If I can figure out what’s different now
compared to my failing version, I’ll report back.

I’m not confident I’ll be able to tell because I just keep hacking
until I get something working. II haven’t taken the time to get
subversion, etc., working.

Do it now, it will save time in the long run. It is difficult to
learn if you are not sure what you did to fix something. Most seem to
be using git now, it is my personal choice. It is trivially easy to
start a repository even when just playing with a new idea.

I’m on.

You’re kidding, right? Git in particular is very quick to set up. Do
it now and you’ll be better able to meet your deadline. There is no
excuse at all for not using version control at all times.
