html - 从 All_Users 页面链接到用户配置文件、路由

Question

尝试使我的 all_users 页面呈现拥有帐户的所有用户的列表 - 然后每个列表项将是指向该用户的个人资料页面的链接。我的页面正确呈现用户名，但它们没有指向其用户页面。他们的用户页面应该是/user/username，但是链接指向/username，这显然会产生错误。我真的非常非常感谢您的帮助。 Stack Overflow 确实令人难以置信。

型号:

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
     attr_accessible :email, :password, :password_confirmation, :remember_me, :username
     has_many :items

  validates_presence_of :username
  validates_uniqueness_of :username

  def to_param
    username
  end

end

Controller :

class UsersController < ApplicationController
  def show
    @user = User.find_by_username(params[:id])
  end
  def index
@user = User.find(:all)
  end
end

所有用户查看:

<div class="well">
  <h1>All users</h1>

  <% @user.each do |user| %>
    <%= link_to user.username, public_profile_path(user.username) %><br/>
  <% end %>
</div>

路线:

Scratch::Application.routes.draw do

  resources :items

  devise_for :users
  match 'users/:id' => 'users#show'
  match '/users', :to => 'users#index', :as => "all_users", :via => "get"
  match ':username' => 'users#show', via: :get, as: :public_profile

  root :to => 'static_pages#home'
  get "about" => "static_pages#about"
end

match '/username/:name' => 'users#show', via: :get, as: :public_profile
