Rails #show 页面只反映第一个种子 object 而不是所有种子对象？

Question

我有一个显示页面连接到我的租赁 object。 在遍历属于租赁的评论时，它只返回第一个评论 object。 我有几个 Review 对象通过我的种子文件连接到每个 Rental，但似乎无法让所有对象都反映。 这是我的文件：

出租/展示.html.erb

<h2> Rental Show Page </h2>

<div class="table-responsive">
<table class="table">
<tbody>
<tr>
<td> <strong> Street Address: </strong> </td>
<td> <%= @rental.street_add %> </td>
</tr>
<tr>
<td><strong> City: </strong></td>
<td><%= @rental.city %></td>
</tr>
<tr>
<td><strong> State: </strong></td>
<td><%= @rental.state %></td>
</tr>
<tr>
<td><strong> Owner: </strong></td>
<td><%= @rental.owner %></td>
</tr>
 </tbody>
</table>

<li><%= link_to 'Edit', rental_path(@rental) %> </li>
<li><%= button_to 'Delete', rental_path(@rental), method: :delete, data: {confirm: "Are you sure?"} %></li>
<li><%= link_to 'Home', rentals_path %></li>

<h1> Reviews </h1>
<% @rental.reviews.each do |reviews| %>
<%= link_to "#{@review.title}", rental_review_path(@rental), class: "btn btn-danger" %>
<% end %>



<h2>Add a review:</h2>
<%= link_to "Add a Review", new_rental_review_path(@rental), class: "btn btn-danger" %>

我的出租屋 Controller

class RentalsController < ApplicationController
 
    def index 
        @rentals = Rental.all
    end
    
    def show
        @review = Review.new
        @review = Review.find_by(id: params[:id])
        return if @rental = Rental.find_by(id: params[:id])
        redirect_to root_path, notice: "Rental is not available"
    end 

    def new
        @rental = Rental.new
    end

    def edit
        @rental = Rental.find_by(id: params[:id])
    end
    
    def create
        @rental = Rental.new(rental_params)
        if @rental.save
          redirect_to @rental, notice: "Your rental has been succesfully added."
        else 
            render :new
        end 
    end

    def update
        @rental = Rental.find_by(id: params[:id])
        @rental.update(rental_params)
        redirect_to @rental, notice: "Your rental has been succesfully updated."
    end
    
    def destroy
        @rental = Rental.find_by(id: params[:id])
        @rental.destroy
        redirect_to root_path
    end 
    
    
    private

    def rental_params
        params.require(:rental).permit(
            :street_add,
            :city,
            :state,
            :owner,
        )
    end

end

还有我的种子文件：

Rental.create(street_add: "1428 Elm Street", city: "Springwood", state: "Ohio", owner: "Fred D. Krueger")

Rental.create(street_add: "112 Ocean Avenue", city: "Amityville", state: "NY", owner: "Butch DeFeo")

Rental.create(street_add: "8601 N Thorne Ln SW", city: "Lakewood", state: "WA", owner: "Kirtland Cutter")


User.create(username: "AAA", email: "test@test1.com", password: "123456")

User.create(username: "BBB", email: "test@test2.com", password: "1234567")

User.create(username: "CCC", email: "test@test3.com", password: "12345678")


Review.create(title: "Weird Dreams, Nice Lawn", body: "Open kitchen space, large green lawn. Had very strange dreams while living here.", rating: 3, rental_id: 1, user_id: 1)

Review.create(title: "Tenant Left Items", body: "Loved the master bedroom, but wasn't thrilled that the tenant left behind items.", rating: 2, rental_id: 2, user_id: 2)

Review.create(title: "Beautiful Furnished Basement", body: "Basement was fully furnished and was able to convert it into an office space. Loved the quiet neighborhood.", rating: 5, rental_id: 3, user_id: 3)

Review.create(title: "Very Cold", body: "The house was next to impossible to heat and was cold even in the summer. Heating costs were through the roof.", rating: 2, rental_id: 2, user_id: 2)

Review.create(title: "I loved it, husband didn't", body: "While I loved the quaint house, my husband was adamant that he didn't. (Something about voices). Great price for the location.", rating: 4, rental_id: 3, user_id: 3)


Review.create(title: "Sprawling Estate", body: "Plenty of space, landlord was very accomodating", rating: 5, rental_id: 1, user_id: 1)

Review.create(title: "Beautiful Trees in Backyard", body: "Beautiful trees in backyard although the owls made strange noises at night.", rating: 3, rental_id: 2, user_id: 2)

Review.create(title: "Stains Under All Rugs", body: "I noticed the rugs were placed oddly, and when lifted to clean the floors revealed large rust stains. We had someone out twice to clean them but they weren't able to be removed. Faucets produced rust colored water as well.", rating: 2, rental_id: 3, user_id: 3)

puts "data loaded success"

我想要完成的是为每个租金列出多个评论。 这是我的租金#show 页面的屏幕截图与所有评论的屏幕截图：

很感谢任何形式的帮助！

更新：我能够通过更新显示页面以反映 link_to 来找到解决方案：

<h2> Rental Show Page </h2>

<div class="table-responsive">
<table class="table">
<tbody>
<tr>
<td> <strong> Street Address: </strong> </td>
<td> <%= @rental.street_add %> </td>
</tr>
<tr>
<td><strong> City: </strong></td>
<td><%= @rental.city %></td>
</tr>
<tr>
<td><strong> State: </strong></td>
<td><%= @rental.state %></td>
</tr>
<tr>
<td><strong> Owner: </strong></td>
<td><%= @rental.owner %></td>
</tr>
 </tbody>
</table>

<li><%= link_to 'Edit', rental_path(@rental) %> </li>
<li><%= button_to 'Delete', rental_path(@rental), method: :delete, data: {confirm: "Are you sure?"} %></li>
<li><%= link_to 'Home', rentals_path %></li>

<h1> Reviews </h1>
<% @rental.reviews.each do |reviews| %>
<li><%= link_to "#{reviews.title}", rental_review_path(@rental, reviews), class: "btn btn-danger" %></li>
<% end %> 

<h2>Add a review:</h2>
<%= link_to "Add a Review", new_rental_review_path(@rental), class: "btn btn-danger" %>

并像这样更新 controller：

class RentalsController < ApplicationController
 
    def index 
        @rentals = Rental.all
    end
    
    def show
        @review = Review.find_by(id: params[:id])
        return if @rental = Rental.find_by(id: params[:id])
        redirect_to root_path, notice: "Rental is not available"
    end 

    def new
        @rental = Rental.new
    end

    def edit
        @rental = Rental.find_by(id: params[:id])
    end
    
    def create
        @rental = Rental.new(rental_params)
        if @rental.save
          redirect_to @rental, notice: "Your rental has been succesfully added."
        else 
            render :new
        end 
    end

    def update
        @rental = Rental.find_by(id: params[:id])
        @rental.update(rental_params)
        redirect_to @rental, notice: "Your rental has been succesfully updated."
    end
    
    def destroy
        @rental = Rental.find_by(id: params[:id])
        @rental.destroy
        redirect_to root_path
    end 
    
    
    private

    def rental_params
        params.require(:rental).permit(
            :street_add,
            :city,
            :state,
            :owner,
        )
    end

end
