Hi, I'm trying to use Data Mapper 0.10.2 in a rails 2.3.5 app with a
few legacy tables. I have a few reserved words as column names, I
only need access to a few columns so listed them as 'property,' and
class works fine in script/console, and in unit tests. When I try to
load a URL for a controller action, I get an unusual error:
---
Showing app/views/things/index.html.erb where line #13 raised:
undefined method `thing__path' for #<ActionView::Base:0x7f17e23a8af8>
Extracted source (around line #13):
10: [td]<%=h thing.name %>[/td]
11: [td]<%= link_to 'Show', thing %>[/td]
12: [td]<%= link_to 'Edit', edit_thing_path(thing) %>[/td]
13: [td]<%= link_to 'Destroy', thing, :confirm => 'Are you
sure?', :method => :delete %>[/td]
14: [/tr]
15: <% end %>
16: [/table]

'Thing' is a simple AR scaffold class I made for this example:
---
create_table "things", :force => true do |t|
t.string "name"
t.datetime "created_at"
t.datetime "updated_at"
end
---
My Data Mapper class (app/models/user.rb):
---
require 'dm-core'
DataMapper.setup(:default, FILTERED)
class User
include DataMapper::Resource
storage_names[:default] = 'user'
property :user_id, Serial
property :company, String
end
---
my controller (app/controllers/things_controller.rb):
---
def index
@things = Thing.all
# load one DataMapper object
@user = User.first
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @things }
end
end
---
I have been able to reproduce this in passenger 2.2.11, and WEBrick
(script/server). If I comment out the User.first line and restart
controller action works. If I put it back action breaks.
/things/show/1 or /new works fine, seems to have something to do with
routes generated by map.resources?
