Deleting Nested Reviews Deletes the whole Post Created - ruby-on-rails

Question

I am setting a nested review scaffold inside the Post scaffold however, when i try to delete a review that is nested inside the show page in the Post, The whole post is deleted. how can i delete only the reviews without the post?
here's my code:
posts_controller.rb
class PostsController < ApplicationController
before_action :set_post, only: [:show, :edit, :update, :destroy]
before_action :authenticate_user! , except: [:index,:show]
before_filter :check_user, only: [:edit,:update,:destroy]
# GET /posts
# GET /posts.json
def search
if params[:search].present?
#posts = Post.search(params[:search])
else
#posts = Post.all
end
end
def index
if params[:tag]
#posts = Post.tagged_with(params[:tag])
else
#posts = Post.all
end
end
# GET /posts/1
# GET /posts/1.json
def show
#reviews = Review.where(post_id: #post.id)
end
# GET /posts/new
def new
#post = Post.new
end
# GET /posts/1/edit
def edit
#post = Post.find(params[:id])
end
# POST /posts
# POST /posts.json
def create
#post = Post.new(post_params)
#post.user_id = current_user.id
respond_to do |format|
if #post.save
format.html { redirect_to #post, notice: 'Post was successfully created.' }
format.json { render :show, status: :created, location: #post }

format.html { render :new }
format.json { render json: #post.errors, status: :unprocessable_entity }
end
end

Update:
i tried changing the code as suggested in the destroy method and in the Reviews Controller and the Post Show page but still getting the error. Here's the error i am getting :

Answer 1

Look like a typo, change:
<p><%= link_to 'Destroy', #review, method: :delete, data: { confirm: 'Are you sure?' } %></p>
to:
<p><%= link_to 'Destroy', review, method: :delete, data: { confirm: 'Are you sure?' } %></p>
and change your reviews controller destroy:
def destroy
#review.destroy
redirect_to :back
end
