Ruby on rails 未定义的方法`user'；在岗位上>；显示视图

当我尝试加载表单时，在posts>show中获取此错误

该表单供用户相互发送消息。感谢您的反馈

谢谢

NoMethodError in Posts#show

ROUTES.RB

Mysalary::Application.routes.draw do

resources :users do
 resources :messages
   end

resources :profiles
resources :pages
resources :posts

get "pages/home"
get "pages/about"
get "pages/legal"
get "pages/feedback"

root :to => 'posts#new'

end

后期模型

class Post < ActiveRecord::Base
attr_accessible :title, :job, :location, :salary

validates :title, :job, :location, :salary, :presence => true 
validates :salary, :numericality => {:greater_than_or_equal_to => 1} 

default_scope :order => 'posts.created_at DESC'
end

class Posttrue
验证：salary，：numerical=>{：大于或等于1}
默认范围：order=>'posts.created_at DESC'
结束

错误是在

Post

模型上没有方法

user

。它直接指向第一行

<%= form_remote_tag (:update => 'message', :url => {:controller => 'main', :action => 'send_message', :user_id => @post.user.id}) do %>

'message'，：url=>{:controller=>'main'，：action=>'send_message'，：user_id=>@post.user.id}）do%>

我得说

---

@post.user.id

是您的问题陈述，该模型没有方法

user

，但如果不查看post模型，就很难确定

我想你错过了添加关系

class Post < ActiveRecord::Base
  belongs_to :user
end

class Post

我在上面添加了post模型。那么，我可以用belowns\u to:user来解决这个问题吗？或者还有其他问题吗？@hikmatyar是的，应该可以解决这个问题，不要忘记将

has\u many:posts

添加到用户模型中。

<%= form_remote_tag (:update => 'message', :url => {:controller => 'main', :action => 'send_message', :user_id => @post.user.id}) do %>

class Post < ActiveRecord::Base
  belongs_to :user
end
