Rails:在视图中显示来自不同模型的表单 [英] Rails: Show form from different model in a view

问题描述

我有一个 location 模型和一个 post 模型.我想允许用户从 location 模型的 index 页面创建新的 posts.我怎么做?我尝试将 post new.html.erb 渲染为 location index.html.erb 中的一部分，但是这会导致错误，因为 post new.html.erb 引用了 @post 变量.

I have a location model and a post model. I want to allow the user to create new posts from the index page of the location model. How do I do that? I tried rendering the post new.html.erb as a partial in location index.html.erb, but this leads to errors as post new.html.erb references the @post variable.

我应该如何做到这一点?

How should I accomplish this?

推荐答案

尝试这样的事情

LocationController

def index
  @location = Location.find(:all)
  @post = Post.new
end

现在你的位置视图可以访问实例变量@post.使用该渲染部分

Now ur location view would have access to the instance variable @post. Render a partial using that

render :partial => 'posts/post', :object => @post
