如何解决Rails #show 页面仅反映第一个种子对象而不是所有种子对象？
我有一个显示页面连接到我的租赁对象。当迭代属于租赁的评论时，它只返回第一个评论对象。我有几个 Review 对象通过我的种子文件连接到每个 Rental ，但似乎无法让所有这些对象都反映出来。这是我的文件：
租金/show.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" %>
我的租赁控制器
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: "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,user_id: 1)
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.",user_id: 2)
Review.create(title: "I loved it,user_id: 3)
Review.create(title: "Sprawling Estate",body: "Plenty of space,landlord was very accomodating",user_id: 1)
Review.create(title: "Beautiful Trees in Backyard",body: "Beautiful trees in backyard although the owls made strange noises at night.",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.",user_id: 3)
puts "data loaded success"
我想要完成的是为每次租赁列出多条评论。这是我在rentals#show 页面上的截图与所有评论的截图：
非常感谢任何帮助！
解决方法
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" %>
并像这样更新控制器：
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
