Rails 3：在控制器内创建方法，Post.new 而不是 current_user.posts.build

我将此作为 PostsController 中的创建方法，

class PostsController < ApplicationController
    def create
        @user = current_user
        @post  = current_user.posts.build(params[:post])
        if @post.save
          flash[:success] = "Post created!"
          redirect_to root_path
        else
           @feed_items = current_user.feed.paginate(:per_page => "10", :page => params[:page])
          render 'pages/home'
        end
      end

我想稍微更改一下以设置 :user_id =>参数[:post][:user_id]。我正在尝试这个，但它不包括 current_user 所以我想知道这些创建方法有何不同，以及如何在 current_user.posts.build(params[:post]) 和 Post.new 中保持相同的功能？

def create
  @post = Post.new :user_id => params[:post][:user_id]
  @post.update_attributes params[:post] 
  if @post.save
    flash[:success] = "Post created!"
    redirect_to root_path
  else
    @feed_items = current_user.feed.paginate(:per_page => "10", :page => params[:page])
    render 'pages/home'
  end
 end  
end

I have this as my create method inside my PostsController

class PostsController < ApplicationController
    def create
        @user = current_user
        @post  = current_user.posts.build(params[:post])
        if @post.save
          flash[:success] = "Post created!"
          redirect_to root_path
        else
           @feed_items = current_user.feed.paginate(:per_page => "10", :page => params[:page])
          render 'pages/home'
        end
      end

I'd like to change it slightly to also set :user_id => params[:post][:user_id]. I'm trying this but it doesn't include the current_user so I am wondering how are these create methods different and how would I keep the same functionality in current_user.posts.build(params[:post]) with Post.new ?

def create
  @post = Post.new :user_id => params[:post][:user_id]
  @post.update_attributes params[:post] 
  if @post.save
    flash[:success] = "Post created!"
    redirect_to root_path
  else
    @feed_items = current_user.feed.paginate(:per_page => "10", :page => params[:page])
    render 'pages/home'
  end
 end  
end

在你的帖子模型中belongs_to：user

def create
  @post = Post.new(params[:post])
  @post.user = current_user
  if @post.save
    flash[:success] = "Post created!"
    redirect_to root_path
  else
    @feed_items = current_user.feed.paginate(:per_page => "10", :page => params[:page])
    render 'pages/home'
  end
 end  
end

in your post model belongs_to :user

def create
  @post = Post.new(params[:post])
  @post.user = current_user
  if @post.save
    flash[:success] = "Post created!"
    redirect_to root_path
  else
    @feed_items = current_user.feed.paginate(:per_page => "10", :page => params[:page])
    render 'pages/home'
  end
 end  
end
