Resource routing error with the route equipment/new

Rails
1

I’m having an issue with resource routing after running a “ruby
script/generate scaffold equipment” command. I did not make any changes
to the equipment model/controller/views after running this.

The full command I ran (all one line) …

ruby script/generate scaffold equipment
name:string description:text contact:text keywords:string
created_at:datetime created_by:integer
updated_at:datetime updated_by:integer

IN config/routes.rb I have the following placed above the default routes
…

map.resources :equipment

–

The following routes work (I added ID#1 directly into the database) …
/equipment
/equipment/1
/equipment/1/edit

The following route fails …
/equipment/new

–

When going to /equipment/new …

ActionController::RoutingError in Equipment#new
Showing equipment/new.html.erb where line #5 raised:
equipment_url failed to generate from {:controller=>“equipment”,
:action=>“show”} - you may have ambiguous routes, or you may need to
supply additional parameters for this route. content_url has the
following required parameters: [“equipment”, :id] - are they all
satisfied?

Extracted source (around line #5):
2:
3: <%= error_messages_for :equipment %>
4:
5: <% form_for(@equipment) do |f| %>
6:


7: Name

8: <%= f.text_field :name %>

I’ve tried adding the following to inflections.rb (one at a time, not
simultaneously) even though I think ‘equipment’ is already in the
standard rails inflections code, and nothing changed …

Inflector.inflections do |inflect|
inflect.uncountable %w( equipment )
end

Inflector.inflections do |inflect|
inflect.irregular ‘equipment’, ‘equipment’
end

–

I also tried changing routes.rb to the following, which caused
equipment/new to work but the other three routes to fail …

map.resources :equipment, :singular => :equipment_instance

–

Any ideas on what could be happening?

THANKS!

Running “rake routes” showed something odd. Instead of “equipment”, the
plain GET route is shown as “equipment_index”. Is there any way to
override/fix this?

      equipment_index GET    /equipment

{:action=>“index”, :controller=>“equipment”}

Nevermind, it has to be ‘equipment_index’ because the plain ‘equipment’
is being used by the ‘show’ action.

And now my first lesson in named resource routes is complete :slight_smile:

David,
I am having the same issue. Do you mind providing the code you used to
fix this issue?

Thanks,
John
