You forgot to update Strong params in section 6.4 (deleting comments)

This is your final code:

class CommentsController < ApplicationController

def create
@post = Post.find(params[:post_id])
@comment = @post.comments.create(params[:comment])
redirect_to post_path(@post)
end

def destroy
@post = Post.find(params[:post_id])
@comment = @post.comments.find(params[:id])
@comment.destroy
redirect_to post_path(@post)
end

end

It should be:

class CommentsController < ApplicationController

def create
@post = Post.find(params[:post_id])
@comment =
@post.comments.create(params[:comment].permit(:commenter,
:body))
redirect_to post_path(@post)
end

def destroy
@post = Post.find(params[:post_id])
@comment = @post.comments.find(params[:id])
@comment.destroy
redirect_to post_path(@post)
end

end
