Hey guys. Just did the admin addition to the recipe app.
I don’t see the “Destroy” or “Delete” on the recipe page.
Here is my code!
app/views/recipes/show.html.erb:
<div class="recipe-show">
<div class="container">
<h2><%= @recipe.name %></h2>
<img class="arrow" src="http://s3.amazonaws.com/codecademy-content/courses/rails-auth/img/arrow.svg" width="80" height="40">
<div class="img_container">
<%= image_tag @recipe.image %>
</div>
<div class="recipe-info">
<p class="ingredients"><%= @recipe.ingredients %></p>
<p class="instructions"><%= @recipe.instructions %></p>
</div>
<!-- Add links here -->
<% if current_user && current_user.admin? %>
<p class="recipe-delete"><%= link_to "Delete", recipe_path(@recipe), method: "delete" %><p>
<% end %>
<% if current_user && current_user.editor? %>
<p class="recipe-edit">
<%= link_to "Edit Recipe", edit_recipe_path(@recipe.id) %>
</p>
<% end %>
</div>
</div>
app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.

def current_user
@current_user ||= User.find(session[:user_id]) if session[:user_id]
end
def require_user
redirect_to '/login' unless current_user
end
def require_editor
redirect_to '/' unless current_user.editor?
end
def require_admin
redirect_to '/' unless current_user.admin?
end
end

class RecipesController < ApplicationController
before_action :require_user, only: [:show, :edit, :update, :destroy]

before_action :require_admin, only: [:destroy]
def show
@recipe = Recipe.find(params[:id])
end
def edit
@recipe = Recipe.find(params[:id])
end
def update
@recipe = Recipe.find(params[:id])
if @recipe.update(recipe_params)
redirect_to @recipe
else
render 'edit'
end
end
def destroy
@recipe = Recipe.find(params[:id])
@recipe.destroy
redirect_to root_url
end
private
def recipe_params
params.require(:recipe).permit(:name, :ingredients, :instructions)
end
end
