Strong_parameters issue with embedded documents in MongoDB using Rails 4 and Mongoid 4.0.0

I'm just trying to set up a blog with Rails using MongoDB for my persistence layer. As part of that I'd like to embed comments in my posts but every time I do, it fails calling ActiveModel::ForbiddenAttributesError, which I know has to do with the strong_parameters gem in Rails. this is what my controller looks like

class CommentsController < ApplicationController

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

  private
    def comment_params
    params.require(:comment).permit(:by, :published_on, :body)
  end
end

Can anyone see where I'm going wrong?

You can't just pass the params hash like you do. You must use the return value of the permit method instead. Like this:

@comment = @post.comments.create!(comment_params)
