用户无法访问我的ruby应用程序中的其他用户

Question

我环顾四周，发现只有一个问题就像我问的问题一样，其中的信息对我的问题没有帮助。我遇到的问题是我的用户，我有几个用户。您可以导航到显示每个用户的页面，每个用户都可以单击。但是，当我登录用户说Profile（1）并且我想访问Profile（2）页面时，它只会加载Profile（1）的凭据。年龄，生物和图片。我的问题在这里？这可能是一个简单的修复，如果是这样，那么请提前感谢您的帮助！

这是列出所有用户的页面index.html.erb，

.CancelAsync()

以下是用户show.html.erb的个人资料页面，

<div class="all_users">
  <div class="container">
    <p id="notice"><%= notice %></p>

    <h1>Listing Users</h1>

    <table>
      <thead>
        <tr>

          <th colspan="3"></th>
        </tr>
      </thead>

      <tbody>
        <% @users.each do |user| %>
        <ul class="media-list">
          <li class="media">
            <div class="media-left">
              <%= link_to image_tag user.profile_picture.url(:thumb) %>
              </a>
            </div>
            <div class="media-body">
              <h4 class="media-heading">Name: <%= link_to user.first_name, dashboard_path %></h4>
              <p>Age: <%= user.age %></p>
              <p><%= user.bio %></p>
           </div>
          </li>
        </ul>
          <tr>
            <td><%= link_to 'Show', user %></td>
            <td><%= link_to 'Edit', edit_user_path(user) %></td>
            <td><%= link_to 'Destroy', @user, method: :delete, data: { confirm: 'Are you sure?' } %></td>
          </tr>
        <% end %>
      </tbody>
    </table>

    <br/>

    <%= link_to 'New User', new_user_path %>
    <%= link_to 'Login', login_path %>
  </div>
</div>

这是我的users_controller.rb，

这是我的用户模型user.rb，

class UsersController < ApplicationController
  before_action :set_user, only: [:show, :edit, :update, :destroy]
  after_action :signed_in_after_register, only: :create 

  def index
    @users = User.all
    @user = User.find(session[:user_id])
  end

  def dashboard 
    @user = User.find(session[:user_id]) unless session[:user_id] == ""
    redirect_to login_path, notice: "You're not logged in" unless @user 
    @posts = @user.posts.order("created_at DESC").limit(3)
    @comment = Comment.new 
    @post = Post.new 
  end 

  def newsfeed
    @user = User.find(session[:user_id]) unless session[:user_id] == nil
    redirect_to login_path, notice: "You're not logged in" unless @user 
    @posts = @user.posts.order("created_at DESC").limit(3)
  end

  def nav
     @user = User.find(session[:user_id])
  end
  def posts
     @user = User.find(session[:user_id])
     @posts = @user.posts
  end

  def destroy
    @user = User.find(session[:user_id]) unless session[:user_id] == ""
    redirect_to login_path, notice: "You're not logged in" unless @user 
  end

  def welcome
    @user = User.find(session[:user_id]) unless session[:user_id] == ""
    redirect_to login_path, notice: "You're not logged in" unless @user 
  end

  def show
    @user = User.find(params[:user_id]) unless session[:user_id] == ""
    redirect_to login_path, notice: "You're not logged in" unless @user 
    @posts = @user.posts.order("created_at DESC").limit(3)
    @comment = Comment.new 
    @post = Post.new 
  end

  def new
    @post = Post.new(params[:post_id])
    @user = User.new
  end

  def edit

  end

  def create
    @user = User.new(user_params)

     respond_to do |format|
      if @user.save
        format.html { redirect_to dashboard_path, notice: 'User was successfully created!' }
        format.json { render :show, status: :created, location: @user }
      else
        format.html { render :new }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
   end
  end

  def update

    respond_to do |format|
      if @user.update(user_params)
         format.html { redirect_to dashboard_path, notice: 'User was successfully updated.' }
        format.json { render :show, status: :ok, location: @user }
      else
        format.html { render :edit }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
    end
  end

  def destroy
    @user.destroy
    respond_to do |format|
      format.html { redirect_to users_url, notice: 'User was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private
    def set_user
      @user = User.find(params[:id])
    end
    def signed_in_after_register 
      session[:user_id] = @user.id 
    end

    def user_params
      params.require(:user).permit(:first_name, :last_name, :bio, :password, :password_confirmation, :email, :age, :profile_picture, :post, :body)
    end
end

我尝试输入User.find（params [：user_id]）并收到以下错误

class User < ActiveRecord::Base
    has_secure_password
    validates :first_name, :last_name, :email, presence: true, uniqueness: true 
    validates_inclusion_of :age, in: 10..100
    validates :password, presence: true 
    has_many :posts
    has_attached_file :profile_picture, :styles => { :medium => "300x300>", :thumb => "100x100>" }, 
    :default_url => "app/assets/images/missing.png", 
    :path => ":rails_root/public/system/:class/:attachment/:id_partition/:style/:filename" 
    validates_attachment_content_type :profile_picture, :content_type => /\Aimage\/.*\Z/

编辑：这是我的路线文件，

ActiveRecord::RecordNotFound in UsersController#show 
Couldn't find User with 'id'=

Answer 1

您点击哪个链接查看用户的个人资料？

<h4 class="media-heading">Name: <%= link_to user.first_name, dashboard_path %></h4>

或：

<td><%= link_to 'Show', user %></td>

如果是第一个，为什么要链接到dashboard_path？似乎应该链接到user_path(user)对吗？

也可能有助于向我们展示您的路线档案。
