Lets say I have a post, this post should have a certian amount of comments, and these comments should be created by certian users. So these are my datamapper models:
class User
include DataMapper::Resource
property :id, Serial
property :name, String,
property :password, String
has n, :post
end
class Post
include DataMapper::Resource
property :id, Serial
property :text, Text
property :created_at, DateTime
belongs_to :user
end
class Comment
include DataMapper::Resource
property :text, Text,
property :created_at, DateTime
belongs_to :post
belongs_to :user
end
So let's say user x creates a post and user y wants to create a comment to this post. How do I do this then? I need something like this:
user = User.get(sessions[:user_id])
post = Post.get(params[:post_id])
comment = post.user.Comment.new {
:text => "Bla",
[...]
}
[...]
comment.save
[...]
So basicly the Model Post should be associated with the Model Comment and the Model Post, how do I realize this?
