使用带有Rails 4.0的friendly_id 5.0 stable
,我得到了一个未找到记录的异常错误:
迁移:
class AddSlugToUsers < ActiveRecord::Migration
def change
add_column :users, :slug, :string
add_index :users, :slug
end
end
控制器:
class UsersController < ApplicationController
load_and_authorize_resource
before_filter :authenticate_user!
def index
authorize! :index, @user, :message => 'Not authorized as an administrator.'
@users = User.all
end
def show
#@user = User.find(params[:id])
@user = User.friendly.find(params[:id])
end
def update
authorize! :update, @user, :message => 'Not authorized as an administrator.'
@user = User.find(params[:id])
if @user.update_attributes(params[:user], :as => :admin)
redirect_to users_path, :notice => "User updated."
else
redirect_to users_path, :alert => "Unable to update user."
end
end
def destroy
authorize! :destroy, @user, :message => 'Not authorized as an administrator.'
user = User.find(params[:id])
unless user == current_user
user.destroy
redirect_to users_path, :notice => "User deleted."
else
redirect_to users_path, :notice => "Can't delete yourself."
end
end
end
数据:
INSERT INTO
users(id,email,encrypted_password,reset_password_token,reset_password_sent_at,remember_created_at,
sign_in_count,current_sign_in_at,last_sign_in_at,current_sign_in_ip,last_sign_in_ip,
created_at,updated_at,first_name,last_name,alias,bio,slug)
VALUES
(10,'me1@example.com','$2a$10$MYHASG','',null,null,0,null,null,'','',
Invalid Date,Invalid Date,'greek','god','tool','','tool');
如果我将ID放入网址
,它就有效 http://0.0.0.0:3000/users/10
但使用slug
时不起作用 http://0.0.0.0:3000/users/tool
答案 0 :(得分:6)
最快的解决方法是使用:readme中使用:finders addon来使用旧的4样式查找器。
然后您将通过“普通”find()方法进行友好ID访问。
示例:
friendly_id :foo, use: [:slugged, :finders] # you can now do MyClass.find('bar')
