未定义的方法`microposts’

它以前工作但为什么现在不是? 我试图只通过signIn用户创建一个post。或者是我的路由问题? 我的路由是资源:用户做资源:微博结束

微博控制器

def create @micropost = current_user.microposts.build(params[:micropost]) if @micropost.save flash[:success] = "Post created!" redirect_to @micropost else render 'new' end end 

new.html.erb

    f.object %>  current_user.id %> 


30, :cols=> 30 %>


微博模型

 class Micropost  'microposts.created_at DESC' attr_accessible :title,:content,:category validates :user_id, :presence => true validates :title, :presence => true, :length => {:maximum =>500} validates :content, :presence => true, :length => {:maximum =>3000} validates :category, :presence => true end 

迁移微博

 class CreateMicroposts < ActiveRecord::Migration def self.up create_table :microposts do |t| t.string :title t.string :content t.string :user_id t.string :category t.timestamps end add_index :microposts, [:title, :created_at, :category] end def self.down drop_table :microposts end end 

您的用户模型需要:

 has_many :microposts
