Rails：當我點擊編輯在我的部分它總是編輯相同的編號

Question

我是一個新手，你可能會從我的文件中看到，我不完全知道我在做什麼:(。我有一個用戶和一個項目模型，一個項目屬於一個用戶，一個用戶有很多項目 我已經創建了一個用戶資料頁面，顯示屬於該用戶的所有項目，我想給用戶一個機會編輯或刪除他的個人資料直接刪除項目目前刪除似乎工作和編輯只適用於用戶第一次點擊「顯示」，然後編輯項目，但當用戶點擊編輯他的個人資料，項目爲被編輯是不是一個點擊。

這是我的個人資料視圖（views/users/show）：

<% provide(:title, @user.name) %> 
    <div class="row"> 
     <aside class="col-md-4"> 
     <section class="user_info"> 
      <h1> 
      <%= @user.name %> 
      </h1> 
     </section> 
     </aside> 
     <div class="col-md-8"> 
     <% if @user.projects.any? %> 
      <h3>Projects (<%= @user.projects.count %>)</h3> 
      <ol class="projects"> 
      <%= render @projects %> 
      </ol> 
      <%= will_paginate @projects %> 
     <% end %> 
     </div> 
    </div> 

這是_project部分與編輯聯繫：

<li id="project-<%= project.id %>"> 

    <span class="title"> 
     Title: <%= project.title %></span><br> 
    <span class="status"> 
    <span class="user"> 
     Submitted By: <%= link_to project.user.name, project.user %></span><br> 
    <span class="description"> 
     Description: <%= project.description %></span><br> 
    <span class="status"> 
     Status:<%= project.status %></span><br> 
    <span class="p_type"> 
     Type: <%= project.p_type %></span><br> 
    <span class="timestamp"> 
    Updated: <%= time_ago_in_words(project.updated_at) %> ago. 
    <% if current_user?(project.user) %> 
     <%= link_to "delete", project, method: :delete, 
             data: { confirm: "You sure?" } %> 
     <%= link_to "edit", edit_project_path %> 
     <%= link_to "New Project!", new_project_path %> 
    <% end %> 
<!-- <%= link_to "show", project, method: :get %> --> 
    </span> 
</li> 

這是我的項目控制器：

class ProjectsController < ApplicationController 
    before_action :logged_in_user, only: [:create, :edit, :destroy] 
    before_action :correct_user, only: [:edit, :destroy] 

    def index 
    @projects = Project.paginate(page: params[:page]) 
    end 

    def show 
    @project = Project.find(params[:id]) 
    end 


    def new 
    @project = Project.new 
    end 

    def create 
     @project = current_user.projects.build(project_params) 
    if @project.save 
     flash[:success] = "Project created!" 
     redirect_to root_url 
    else 
     @feed_items = [] 
     render 'new' 
    end 
    end 

    def edit 
    @project = Project.find params[:id] 
    end 

    def update 
    @project = Project.find params[:id] 
    @user = User.find(params[:id]) 
    if @project.update(project_params) 
     flash[:success] = "Project updated" 
     redirect_to user_path(@user) 
    else 
     render 'edit' 
    end 
    end 

    def destroy 
    @project.destroy 
    flash[:success] = "Project deleted" 
    redirect_to request.referrer || root_url 
    end 


    private 

    def project_params 
     params.require(:project).permit(:description, :title, :status, :p_type) 
    end 

    def correct_user 
     @project = current_user.projects.find_by(id: params[:id]) 
     redirect_to root_url if @project.nil? 
    end 
end 

我的項目模型：

class Project < ApplicationRecord 
     belongs_to :user 
     default_scope -> { order(updated_at: :desc) } 
     validates :user_id, presence: true 
     validates :description, presence: true, length: { maximum: 250 } 
     validates :title, presence: true, length: { maximum: 60 } 
     validates :p_type, presence: true 
     validates :status, presence: true 
    end 

我的路線文件：

Rails.application.routes.draw do 

    root 'static_pages#home' 

    get '/help', to: 'static_pages#help' 
    get '/about', to: 'static_pages#about' 
    get '/contact', to: 'static_pages#contact' 
    get '/signup', to: 'users#new' 
    get '/login', to: 'sessions#new' 
    post '/login', to: 'sessions#create' 
    delete '/logout', to: 'sessions#destroy' 

    resources :users 
    resources :account_activations, only: [:edit] 
    resources :password_resets,  only: [:new, :create, :edit, :update] 
    resources :projects 

end 

最後，如果有幫助，當我做編輯操作，這是跟蹤：

也增加了編輯表單

<% provide(:title, "Edit Project") %> 
<h1>Update your Project</h1> 

<div class="row"> 
    <div class="col-md-6 col-md-offset-3"> 
    <%= form_for(@project) do |f| %> 
     <%= render 'shared/error_messages', object: f.object %> 

     <%= f.label :title %> 
     <%= f.text_field :title, class: 'form-control' %> 

     <%= f.label :p_type %> 
     <%= f.select :p_type, ([['QuickWin', 'QuickWin'], 
     ['Project', 'Project']]) %> 

     <%= f.label :status %> 
     <%= f.select :status, ([['Not Yet Started', 'Not Yet Started'], 
      ['In Progress', 'In Progress'], ['In Testing', 'In Testing'], 
      ['On Hold', 'On Hold'], ['Launched', 'Launched']]) %> 

     <div class="field"> 
     <%= f.text_area :description, placeholder: "Briefly summarise the purpose of this project..." %> 
     </div> 

     <%= f.submit "Save changes", class: "btn btn-primary" %> 
    <% end %> 

    </div> 
</div> 

預先感謝您的幫助！

Answer 1

在以下行缺少什麼記錄，你想改變：

<%= link_to "edit", edit_project_path %> 

添加到「edit_project_path」項目參考：

<%= link_to 'edit', edit_project_path(project) %> 

我希望這可以幫助您。

關於錯誤呼叫@user = User.find（[：ID] PARAMS） 「找不到用戶與 'ID'= 424」 您的評論...

當你點擊提交時，你在控制器projects_controller.rb上發送一個PUT動作，用帶有Project對象的params來更新方法。

在您的projects_controller.rb中，您的方法'update'接收一個Project對象。

這裏PARAMS必須顯示爲

params = { ... project:{:title => '...' , :ptype => ..}, 'id' => XXX } 

這個 '身份證' 是project.id！

projects_controller。RB文件

def update 
    @project = Project.find params[:id] 
    @user = User.find(params[:id]) <= you try to find a User with project.id 

我想你想找到的用戶在這個「項目」加盟。

@user = @project.user
