我正在尝试在 Property#show 视图中添加租户用户。我有一个表格，如下所示：

<%= form_for(@property.tenants) do |f| %>
   <div class="field">
    <%= f.label :name %><br />
    <%= f.text_field :name %>
  </div>
  <div class="field">
    <%= f.label :email %><br />
    <%= f.text_field :email %>
  </div>
  <div class="select">
  <%= f.select :type, [['Landlord'],['Tenant']] %>
  </div>
  <%= f.submit "Add", %>  
<% end %>

租户模型如下：

class Tenant < User
  belongs_to :property
  def type
  "Tenant"
  end
end

属性模型如下：

class Property < ActiveRecord::Base
  attr_accessible :address, :bathrooms, :bedrooms, :postcode, :price
  belongs_to :branch
  belongs_to :user

  has_many :ownerships
  has_many :landlords, :through => :ownerships

  has_many :tenants
end

当我单击添加按钮时，我被神奇地重定向到根路径 (/)。我希望它为我在显示视图中查看的特定属性添加一个新租户，但它只是将我重定向到根路径。

在你的 properties_controller.rb,

def show
 @tenant = Tenant.new
end

你的 from 应该是：

<%= form_for @tenant do |f| %>

您还应该在提交表单时添加一个带有属性 ID 的隐藏字段。

然后为您的创建操作properties_controller.rb

def create
   tenant = Tenant.new(params[:tenant])
   tenant.property_id = params[:property_id] #This is from that hidden field with your property_id and this also assumes you have a column in your tenant table for property_id
   tenant.save

   #the shorter way would just be tenant = Tenate.create(params[tenant]) but I want to emphasize the property_id since this attribute is paramount to your property-tenant relationship
end

这应该有效地为新租户创建一个表单，并且当您创建实际租户记录时，您将使用新租户记录保存属性 ID。

另一方面，我建议根据 Rails 约定将其移至租户控制器，并将表单置于新操作下，因为您实际上是在创建新的租户记录。

我认为有几件事似乎不太正确。

尝试这个。

将 @tenant 实例变量添加到 Properties 控制器的 show 方法中。

def show
  ...
  @tenant = @property.tenants.build
end

并将 form_for 行修改为此。

<%= form_for @tenant do |f| %>
