Hi all,

I have a model Post and a model User. The post has a user\_id foreign  
key. What is the best way (railsway) to get all the posts from 1 user?  
Like  
user = User.find(id)  
posts = user.Node.find()

This doesn’t work?

Thank,  
Stijn

hi! try this

in model “Post” add the following line:  
belongs\_to :user, :class\_name =\> ‘User’, :foreign\_key =\> ‘user\_id’

in model “User” add this  
has\_many :posts, :class\_name =\> ‘Post’

then you can do  
user = User.find(id)  
posts = user.posts

user has\_many :posts  
post belongs\_to :user

user = User.find(id)  
posts = user.posts
