私はうまくいくはずの単純な関連付けを試みています。http://ruby.railstutorial.org/chapters/および第 10 章のチュートリアルに従いました。
ここに私が書き留めたもの
モデル/顧客
class Customer < ActiveRecord::Base
has_many :posts, dependent: :destroy
attr_accessible :name, :email, :password, :password_confirmation
has_secure_password
モデル/役職
class Post < ActiveRecord::Base
belongs_to :customer
attr_accessible :description, :post_finish_at, :post_how, :post_location
コントローラー/顧客
class CustomersController < ApplicationController
before_filter :signed_in_customer, only: [:edit, :update]
before_filter :correct_customer, only: [:edit, :update]
def index
@customers = Customer.all
end
def show
@customer = Customer.find(params[:id])
@posts = @customer.posts
end ...
controller/post -- 部分クラス PostsController < ApplicationController を実行しているため、無関係である必要があります
# GET /posts
# GET /posts.json
def index
@posts = Post.all
respond_to do |format|
format.html # index.html.erb
format.json { render json: @posts }
end
end
# GET /posts/1
# GET /posts/1.json
def show
@post = Post.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: @post }
end
end
# GET /posts/new
# GET /posts/new.json
def new
@post = Post.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: @post }
end
end
# GET /posts/1/edit
def edit
@post = Post.find(params[:id])
end
# POST /posts
# POST /posts.json
def create
@post = Post.new(params[:post])
respond_to do |format|
if @post.save
format.html { redirect_to @post, notice: 'Post was successfully created.' }
format.json { render json: @post, status: :created, location: @post }
else
format.html { render action: "new" }
format.json { render json: @post.errors, status: :unprocessable_entity }
end
end
end
# PUT /posts/1
# PUT /posts/1.json
def update
@post = Post.find(params[:id])
respond_to do |format|
if @post.update_attributes(params[:post])
format.html { redirect_to @post, notice: 'Post was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @post.errors, status: :unprocessable_entity }
end
end
end
# DELETE /posts/1
# DELETE /posts/1.json
def destroy
@post = Post.find(params[:id])
@post.destroy
respond_to do |format|
format.html { redirect_to posts_url }
format.json { head :no_content }
end
end
end
ビュー/顧客/show.html.erb
<div class="posts">
<%= render 'posts/post'%>
</div>
ビュー/投稿/_post.html.erb
<li>
<%= @posts.each do |post| %>
<%= post.title %>
<% end %>
</li>
出力は次のようになります
- []
なんで?
ありがとう
