关联数据库如何获取其外键？
我对默认控制器做了很多修改，现在我无法在创建时填充我的 user_id 。
我很好奇它是如何填充的。如果您有兴趣，请查看我的路线和模型关联，然后最后我将向您展示生成的参数。最终结果是没有添加 user_id 。
routes
resources :users do
resources :posts do
collection do
get :view
end
end
end
models
#Post.rb
belongs_to :user, :touch => true
#User.rb
has_many :posts
我导航到这个网址..
http://localhost:3001/users/1/posts/new
并放置我的帖子，params 返回这个：
{"commit"=>"save", "post"=>{"name"=>"hell hath no furry", "category"=>"vegan", "url"=>"www.reddit.com", "text"=>"", "is_link"=>"1"}, "authenticity_token"=>"aYnSLgJ9E6MaM6iSkRrCyyiMZj06oLdybTMkNqss8FA=", "utf8"=>"✓", "action"=>"create", "controller"=>"posts"}
这之前是有效的，不知道为什么它不再关联它们。
有什么想法吗？
I did a bunch of gutting to my default controllers and now I can't get my user_id to populate on create.
I was curious how that gets populated. If you're interested, take a look at my routes, and model assocations, and then at then end I'll show you the resulting params..The end result is no user_id being added.
routes
resources :users do
resources :posts do
collection do
get :view
end
end
end
models
#Post.rb
belongs_to :user, :touch => true
#User.rb
has_many :posts
I navigate to this url..
http://localhost:3001/users/1/posts/new
and place my post, and the params return this :
{"commit"=>"save", "post"=>{"name"=>"hell hath no furry", "category"=>"vegan", "url"=>"www.reddit.com", "text"=>"", "is_link"=>"1"}, "authenticity_token"=>"aYnSLgJ9E6MaM6iSkRrCyyiMZj06oLdybTMkNqss8FA=", "utf8"=>"✓", "action"=>"create", "controller"=>"posts"}
This was working before, not sure why its not associating them anymore.
Any ideas?

在您的 form_for 中，您是否传递了@user？
也许这会有所帮助：

In your form_for, are you passing in the @user?

嗯，我不喜欢回答自己的问题，但我找到了这个解决方案，并且想知道这是否是实现此目标的可接受的方式。
在我的
def create控制器中，我这样做：而不是这样：
Hmm I don't like answering my own questions, but I found this solution, and was wondering if this is an acceptable way of accomplishing this.
In my controller for
def create, I do this :instead of this :
