rails: link_to / form_for doesn't work for singular resource

For anyone landing here via google, this is what got implemented: http://edgeguides.rubyonrails.org/routing.html#singular-resources

In short, add something like resolve('User') { [:user] } after you define the singular resource in routes.rb, where ‘User’ is the class name and :user is the resource name.

To anyone stumbling upon this issue, the workaround is quite simple. Given:

resource :billing_info

You generate the form_for call like this:

= form_for @billing_info, url: billing_info_path do |f|

Not sure if it can help to fix the overall problem but I helped myself the following way, since https://github.com/rails/rails/issues/1769#issuecomment-9556381 did not work properly for my new action

form_for(@equipment, :url=> {:action=> (@equipment.new_record? ? 'create' : 'update')}) do |f|

EDIT: slightly modified to make it work also when validation errors come up.

Couldn’t this be fixed in the latest rails implementation by changing the behavior of form_with?

In case anybody is looking for a workaround:

class Company < ActiveRecord::Base
  model_name.instance_variable_set(:@route_key, 'company')
end

Yeah, it does handle both :create and :update actions.

Yep, here too, my first time with singular resource, lost 3h coz i was blaming myself like a first

i think this bug should be written in rails guides somewhere.

for anyone using a singular resource, they will eventually find themselves on this bug page. better to announce first
