Ruby on Rails 4 渲染部分不渲染

Question

几个月来我一直在尝试将旧的 Rails 2.X 网页升级到 Rails 4。我仍在为一些局部渲染视图而苦苦挣扎。所以我想我需要一些帮助。如果对某人有帮助，我已经保存了我所有的 upgrade notes。但是这个我想不通。

目前的问题是下面的代码只打印地址表（见评论）。

views/users/_seller.erb:

<table class="labels">
<tr>
  <td>{Seller type}</td>
  <td><%= seller.select(:stype, ["producer","distributor","store"]) %></td>
</tr>
(...)
<h3>{Store/Pickup address}</h3>
<% seller.fields_for :address do |address_fields| %>
<!-- THIS IS NOT RENDERED!! -->
<table class="labels">
<tr>
  <td>{Address Line 1}</td>
  <td><%= address_fields.text_field :line1 %></td>
</tr>
<!-- UP TO THERE IS NOT RENDERED!! -->
<% end %>

这个局部视图被调用： views/users/create_seller.html.erb:

<h1>{Before you sell a product, please enter your seller information}</h1>

<%= form_for @seller, :url => "/seller/create" do |f| %>
  <h2>form</h2>
  <% @seller.errors.full_messages.each do |msg| %>
     <p><%= msg %></p>
  <% end %>
  <%= render partial: "seller", locals: {seller:f} %>
  <%= f.submit "Submit" %>
<% end %>

如果你需要看我的模型。我认为它很好，因为它在旧版本中工作： models/seller.rb

class Seller < ActiveRecord::Base
  belongs_to :user

  belongs_to :address, :class_name => "Address", :foreign_key => 'address_id'
  accepts_nested_attributes_for :address, :allow_destroy => true
  belongs_to :shipping_address, :class_name => "Address", :foreign_key => 'shipping_address_id'
  accepts_nested_attributes_for :shipping_address, :allow_destroy => true
end

这是控制器代码

controllers/users_controllers.rb

def create_seller #get
  @user = @current_user
  @seller = Seller.new
  @seller.tax1 = 500
  @seller.tax1_name_fr = "TPS"
  @seller.tax1_name_en = "GST"
  @seller.tax2 = 950
  @seller.tax2_name_fr = "TVQ"
  @seller.tax2_name_en = "QST"
  @seller.build_address
  @seller.build_shipping_address
end

Answer 1

<% seller.fields_for :address do |address_fields| %>

应该是

<%= seller.fields_for :address do |address_fields| %>

请注意 <% 之后的“=”符号以显示输出我相信您已经意识到这一点，但是在 erb 标签中使用 = 符号是版本 2.xx[= 之后的重大变化13=]
