NoMethodError in Blog::PostsController#create

Question

Note: Rails newb here.

So, I recently created a Rails app with mongoid gem for use of MongoDB. I have a namespace route of :blog with a nest of resource of posts

Routes.rb:

Rails.application.routes.draw do
  namespace :blog do
    resources :posts
  end
end

The error comes from app/controllers/blog/posts_controller.rb:

Class Blog::PostsController < ApplicationController
  def create
   @post = Post.new(post_params)

  if @post.save
    redirect_to @post
  else
    render 'new'
  end
 end

 private
 def post_params
 params.require(:post).permit(:title, :body)
 end
end

I also have a 'post' model that comes with a title and body:

Class Post
 include Mongoid::Document
 field :title, type: String
 field :body, type: String
end

In new.html.erb:

<h1>Rails Sample Blog</h1>

<%= form_for @post, url: blog_post_path do |f| %>
  <div><%= f.label :title %><%= f.text_field :title %></div>
  <div><%= f.label :body %><%= f.text_area :body %></div>
<% end %>

Is there something I left out that I didn't catch? It's slowly haunting me.

Edit 2:

undefined method `post_url' for #<Blog::PostsController:0x007f3d19105ee8>

Answer 1

 app/controllers/blog/post_controller.rb:

Shouldn't this be posts_controller.rb?

Also

Class Blog::PostController < ApplicationController

should be

Class Blog::PostsController < ApplicationController

Answer 2

Try this:

 def create

 @blog = Blog.find(params[:blog_id])

 @post= @blog.posts.build(post_params)

(This assumes that you already added a column of blog_id and have your associations correct, although looking at your model it looks like you may have missing associations?)
