If this is line #5 (where the error was reported below), then admin_user is nil. > <p>Category: <%= link_to @post.category.name, > category_path(@post.category.id) %></p> If this is line #5, then category is nil. If this were me, I'd poke in the rails console and see what the record settings are, why either of those might be nil, and where they were supposed to be set for the post record. > <%= 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> > > > > Showing c:/Sites/blog/app/views/posts/show.html.erb where line #5 raised: > > undefined method `name' for nil:NilClass > > > --------------- > > 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 > # Include default devise modules.
