Question

Here is the situation

• User has_many Posts
• User has_many Replies
• Post has_many Replies

Problem is when I add new reply using

@reply = current_user.posts.find(params[:post_id]).replies.new(params[:reply])

In the Replies it only saves the post_id and user_id is null, and if I used current_user.replies.new(params[:reply]) to save the post I get user_id but post_id becomes null

So how to add a reply to have reference for both post_id and user_id? Anyone got a clue!

Answer 1

Maybe your association like this:

User Model

has_many :posts
has_many :replies

Post Model

belongs_to :user
has_many :replies

Reply Model

belongs_to :post
belongs_to :user

So, you can find a post:

@post = Post.find(params[:post_id])

Add new reply to post:

@reply = @post.replies.build(params[:reply])
@reply.user_id = current_user.id
@reply.save
