我正在尝试在我的简单Rails应用程序上进行设计;
1。我希望当user_signout退出时,它将重定向到主页(根)。!
2。用户创建自己的产品时,转到products.index时,它将显示用户创建的所有产品,并且以特定用户身份登录后,该人将在上看到自己创建的产品用户仪表板。(当前添加的产品将自动添加到产品索引页面)
非常感谢!

从正式的设计指南中退出后重定向:
简而言之,将其添加到您的应用程序控制器中:
class ApplicationController < ActionController::Base
...
...
private
# Overwriting the sign_out redirect path method
def after_sign_out_path_for(resource_or_scope)
root_path
end
end

关于问题1:
检查@Mark答案
关于问题2:
假设您有恋爱关系
# app/models/user.rb
class User < ApplicationRecord
has_many :products
end
# app/models/product.rb
class Product < ApplicationRecord
belongs_to :user
end
在user#show
实现中添加
# app/controller/users_controller.rb
def show
...
@products = current_user.products
...
end
现在,在users/show
视图中,您可以为用户的产品循环@products
。
<h1>User products</h1>
<table>
<tr>
<th>Name</th>
<th>Description</th>
<th>Condition</th>
</tr>
<% @products.each do |product| %>
<tr>
<td><%= product.name %></td>
<td><%= product.description %></td>
<td><%= product.condition %></td>
</tr>
<% end %>
</table>
