I got a NoMethodError when i called <%= @post.admin_user.name %>, don't
know how to fix it.



Extracted source (around line #4):

    <h1><%= @post.title %></h1>
    <p><%= @post.body %></p>
    <small>Post created at <%= @post.created_at.strftime('%b %d. %Y')
%></small><br/><br/>
    <%= @post.admin_user.name %>
    <p>Category: <%= link_to @post.category.name,
category_path(@post.category.id) %></p>
    <%= link_to 'Edit Post', edit_post_path %> | <%= link_to 'Go Back',
posts_path %> |     <%= link_to 'Delete Post', @post, :confirm => "Don't
do
it man!", :method => :delete %>
    </div>

This is my posts_controller.rb



      class PostsController < ApplicationController
         def index
     @post = Post.all


      end

      def new
     @post = Post.new
     @category = Category.all
      end


      def create
      @post = Post.new(post_params)
       if @post.save
       redirect_to posts_path, :notice => 'Your post has been posted!'
       else
       render 'new'
       end
      end


      def post_params
          params.require(:post).permit(:title, :body, :category_id,
:admin_user_id, :admin_user, :name)
      end


      def edit
      @post = Post.find(params[:id])
      end

      def update
      @post = Post.find(params[:id])
      if @post.update_attributes(post_params)
         redirect_to post_path, :notice => 'Your post has been updated.'
         else
         render 'new'
        end
      end

      def show
      @post = Post.find(params[:id])
      @user = AdminUser.all
      end

      def destroy
      @post = Post.find(params[:id])
          @post.destroy
          redirect_to posts_path, :notice => 'Your post has been
deleted.'
       end




       end








This is my post.rb

    class Post < ActiveRecord::Base

      belongs_to :category

     belongs_to :admin_user


    end

My admin_user.rd

    class AdminUser < ActiveRecord::Base

      # :confirmable, :lockable, :timeoutable and :omniauthable
      devise :database_authenticatable,
