I'm using the friendly_id gem. I also have my routes nested:
# config/routes.rb
map.resources :users do |user|
user.resources :events
end
So I have URLs like /users/nfm/events/birthday-2009
.
In my models, I want the event title to be scoped to the username, so that both nfm
and mrmagoo
can have events birthday-2009
without them being slugged.
# app/models/event.rb
def Event < ActiveRecord::Base
has_friendly_id :title, :use_slug => true, :scope => :user
belongs_to :user
...
end
I'm also using has_friendly_id :username
in my User model.
However, in my controller, I'm only pulling out events pertinent to the user who is logged in (current_user):
def EventsController < ApplicationController
def show
@event = current_user.events.find(params[:id])
end
...
end
This doesn't work; I get the error ActiveRecord::RecordNotFound; expected scope but got none
.
# This works
@event = current_user.events.f开发者_JAVA百科ind(params[:id], :scope => 'nfm')
# This doesn't work, even though User has_friendly_id, so current_user.to_param _should_ return "nfm"
@event = current_user.events.find(params[:id], :scope => current_user)
# But this does work!
@event = current_user.events.find(params[:id], :scope => current_user.to_param)
SO, why do I need to explicitly specify :scope if I'm restricting it to current_user.events anyway? And why does current_user.to_param need to be called explicitly? Can I override this?
I had the exact same problem with friendly_id 2.2.7 but when I updated to friendly_id 3.0.4 in my Rails 2.3.5 app, everything works. I have test all 4 find invocations you mentioned in my app and they work.
Something to take note of are a few API changes that may affect you. The ones I ran into were:
:strip_diacritics
has been replaced with:strip_non_ascii
.I decided to switch to Stringex's
String#to_url
instead by overridingnormalize_friendly_id
resource.has_better_id?
is now!resource.friendly_id_status.best?
resource.found_using_numeric_id?
is nowresource.friendly_id_status.numeric?
